Box Blight by Ingrid Goodbody

Published in RHSI Journal Autumn 2022

Box Blight
I live in a Georgian House in Old Connaught, near Bray. I have a garden circa one acre and a walled front garden with a pedestrian entrance. When we moved to this house in 1988 with our young family, I became interested in box hedging and planned out the front garden. I propagated all the plants from a box bush I rescued from a house in Shankill which was demolished in the early 1990s to make way for the M11. Over the next 20 years I propagated more than 130m of box and planted the front garden first

I became inspired with the success of the box hedging and expanded into the back garden. I was aware of box blight but naively thought that as I had never used imported plants in the hedging, that my hedges were not vulnerable. Also, to my shame, I never fed the plants, and assumed my homemade compost was enough.
I have been careful to have the box cut by professionals and up to last December, 2021 all was well.
Just before Christmas, I noticed a large area of discoloured leaves on the top of the hedging leading up to the back door.

I immediately examined the rest of the box hedging and noticed some discolouration in other areas but it looked more like rust. I contacted the gardening advisory section available to RHS members, in Wisley, and asked for help. It was not an option to send diseased leaves and branches to the UK, but I sent photographs. One of the scientists replied very quickly to say it looked like box blight, probably Volutella buxi which is the less serious box blight and has been present in the UK and Ireland for many years. This fungus spreads in wet humid conditions and indeed we did have an exceptionally warm late autumn in 2021. Pinkish spores appear on the underside of the leaves, and are carried in water splashes to new sites. Fallen leaves carry the disease over the winter and new spores are produced in the spring. Volutella enters the plant through clipping cuts and other forms of damage to the leaves and stems.
The other box blight Cylindrocladium buxicola is more serious and has been present in the UK and Ireland since the mid-1990s. The leaves develop dark brown spots which enlarge to affect leaf tissues. Patches of greyish fungal growth appear on the underside of the leaves and spores are soon released to spread infection. Black streaks appear on the stems. The spores are capable of penetrating the leaf surface, so wounding via pruning cuts is not necessary for infection to occur. The infected leaves easily fall off the plant and the stems are typically left bare. Cylindrocladium requires moist conditions to thrive, so the spores die in dry conditions. Live spores have been found in decomposing leaves after one year, so it is important to remove any debris, burn if possible, and never put clippings on the compost heap.
From looking at the original photographs, the scientists thought there might be some evidence of caterpillars of the moth Cydalima perspectalis. It was thought by enlarging my photos, that there might be evidence of chewed leaves. I could find no caterpillars and was most distressed at this point having watched Monty Don in the gardens of the Adriatic, where the wonderful ancient parterres of box have been totally devastated by the caterpillars defoliating the plants.
I was advised that the way to deal with this disease is to remove the box hedging and replant with something else. However, I found it difficult to even think of destroying twenty years of work so I decided to try to manage the disease.
It is difficult to completely eliminate box blight, but it is possible to reduce the impact of the disease with good management.
The priority is to remove as much inoculum (infected material which could be carrying spores) from the hedge as possible.
My most infected hedge was removed and as I cannot burn material, it was sent off to the council green waste facility Green King on the way to Gorey, where the temperatures are extremely hot, and will kill off any spores.
The rest of the hedging was cut by 1/3, to healthy tissue, by professional topiary cutters, with sharp sterilised clippers. This removes the inoculum, and also creates a more open structure. All the cuttings were removed from the centre of the hedge which was now very bare, and from underneath as well. This was a monumental job and very hard on my hands and arms. It was advised to sterilise clippers and secateurs between use on healthy and diseased areas. This should be carried out in dry conditions. Clothes should be washed immediately.

It is advised to reduce humidity in box hedging by removing overhanging vegetation, and not applying overhead watering.
I used TopBuxus health mix which is a foliar feed and can be used frequently during the year March to December
I used TopBuxus XenTari as a foliar spray against the Box moth caterpillar. It is indicated three times a year to coincide with the moth laying the eggs and the eggs hatching. It is a biological insecticide and contains a natural potent strain of Bacillus thuringiensis which controls the caterpillars. It is not harmful to humans, wildlife or beneficial insects such as bees for pollination, or insect predators. I also got Pheromone traps for the moths which are indicated in May, and end of July.
The cut box hedging has recovered amazingly well and all the cut bare stems in the middle have healthy new growth. I have found no moths in the Pheromone traps. I have found no caterpillars so far.
Photo 4 – View of regeneration of growth after the hedge was cut by 1/3

But … after the extremely wet weather we had at the end of the dry spell from July to August 2022, I have noticed some discoloured leaves again now in mid-September, which is discouraging.
I have been advised not to have the hedge cut again until the Spring by the RHS gardening advice section to give the recent regrowth time to mature.
Photo 5 – Encouraging growth over the summer in the front garden
I have been actively looking for alternatives to Buxus sempervirens but have found nothing which can compare. I have another box hedge of a different species, which has a more open growing habit, and can be moved to the front garden if necessary if my management of the present box does not work. I know there is a section in Wisley where there are trials on alternatives to box, and I hope to go over there myself in the Spring.
I hope this has been of some use to those of you who are quaking in your boots at the prospect of your beautiful box hedges and topiaries succumbing to diseases of box. Box blight can be managed fairly successfully but is it worth the scratches, effort time and expense?
The jury is out!!!

September Gardening: Preparing for a Blooming Spring

As the days begin to shorten and the first hints of autumn color the landscape, gardeners are already looking ahead to the vibrant displays of spring. September is the ideal time to start planning and planting bulbs that will burst into bloom after the winter months. Ireland’s mild climate offers perfect conditions for a wide variety of spring-flowering bulbs, and with a little forethought and preparation now, your garden can be a riot of color come March and April.

Why September?

September is the ideal time to start planning and purchasing your spring bulbs. As the summer draws to a close, garden centers are fully stocked with a wide variety of bulbs, giving you the best selection to choose from. Shopping early ensures you can pick the healthiest bulbs and secure those in-demand varieties before they sell out. It’s also the perfect month to carefully plan your garden’s layout, considering color schemes, bloom times, and planting combinations. By purchasing and planning in September, you’ll have everything ready to plant at the optimal time, setting the stage for a spectacular spring display.

Choosing the Right Bulbs
Ireland’s temperate climate, with its mild winters and cool summers, is perfect for many types of spring bulbs. Here are some top recommendations:

Daffodils (Narcissus): These hardy bulbs thrive in Ireland’s climate and are one of the first to bloom in spring. Varieties such as ‘February Gold’ and ‘Tête-à-Tête’ are particularly reliable.
Tulips: While tulips prefer well-drained soil, they do well especially if planted in a sunny, sheltered spot. Look for varieties like ‘Red Riding Hood’ or ‘Queen of Night’ for a stunning display.
Crocuses: These small but vibrant flowers are perfect for naturalizing in lawns or under trees. The early-flowering Crocus ‘Tommasinianus’ is a good choice for our climate.
Hyacinths: With their intoxicating fragrance, hyacinths are a must for any garden. They prefer a sunny location and well-drained soil. The ‘Blue Jacket’ variety offers striking deep blue blooms.
Snowdrops (Galanthus): Snowdrops are a beloved harbinger of spring, often flowering as early as January. They prefer shaded areas and moist, well-drained soil but these are best planted in the green.

Where to Buy and What to Look For
When purchasing bulbs, quality is key. Look for firm, healthy bulbs without any signs of mold or rot. Reputable garden centers and online suppliers provide the best quality. It’s also worth seeking out local garden clubs or markets where you might find unique or heritage varieties.

Planting Tips: Timing and Techniques
Timing
Daffodils and Crocuses: These should be planted first, ideally in late September, as they require a longer period to establish.
Tulips: Plant tulip bulbs later in October or even early November to avoid the risk of fungal diseases like tulip fire, which can be more prevalent in warm, wet conditions.
Planting Depth and Spacing
Daffodils: Plant at a depth of about three times the height of the bulb (usually 10-15cm deep) and space them 10-15cm apart.
Tulips: Plant deeper, around 15-20cm, and space them 10cm apart for a dense display.
Crocuses: These can be planted around 5-8cm deep and 5cm apart, ideal for creating naturalized drifts.
Creative Planting Ideas: The Bulb Lasagna
One of the most effective ways to maximize the impact of your spring bulbs is by planting a bulb lasagna. This method involves layering different types of bulbs in a single container or bed, ensuring a continuous display of blooms throughout the spring.

How to Plant a Bulb Lasagna:

Choose a large container or deep bed: Ensure it has good drainage.
Layer 1: Start with late-flowering bulbs like tulips, planting them at the deepest level (15-20cm).
Layer 2: Add a layer of compost, then plant mid-season bulbs like daffodils or hyacinths at around 10-15cm.
Layer 3: Finally, cover with more compost and plant early-flowering bulbs like crocuses at a depth of 5-8cm.
Top Layer: Add a final layer of compost and consider planting winter pansies or other hardy annuals to provide color through the winter until the bulbs emerge.
This technique not only saves space but ensures a succession of blooms, creating a dynamic display from early spring to late May.

Final Tips for Success
Watering: After planting, water the bulbs well to help them settle in. During the winter, the natural rainfall in Ireland is usually sufficient, but ensure the soil remains moist.
Mulching: Apply a layer of mulch to protect the bulbs from frost and to keep the soil temperature stable.
Labeling: If you’re planting a variety of bulbs, consider labeling them so you remember what’s where—this is especially useful when it comes to future garden planning.

By taking the time in September to plan and plant your spring bulbs, you’ll set the stage for a glorious display that will bring joy and color to your garden when the long winter finally comes to an end. Happy planting!

Glenarm Castle Walled Garden

Partner Garden Visit

Glenarm Castle Walled Garden
Now an RHSI Partner Garden, the four-acre Glenarm Castle Walled Garden sits within the large estate of the Earl and Countess of Antrim on the far northeast coast of our island. A visit with a gardening friend on a recent glorious day confirmed the well-held view that this is a complete jewel of a garden. Absolutely worth our three-hour drive from Dublin! The little seaside village of Glenarm nestles into the Antrim coast and is reached once off the main motorways, via quiet rural roads with breathtaking scenery. Just above the village, parking is in the castle grounds along with several good eating choices for teas or lunch. There is also a lovely welcome centre and several artisan shops to visit. Thence to the Walled Garden….

This is accessed through a small and very pretty enclosed Kitchen Garden where a select and very healthy-looking collection of vegetables are presented in raised beds surrounded by low espaliered fruit. Artichokes, cabbages, lettuces, beans, potatoes and onions mingle with tall obelisks of sweet pea whilst against a nearby whitewashed wall fig trees with nasturtiums at their feet bask in the sun.

A gate from this area magically opens through to the south facing aspect of what is known as the older, lower part of the walled garden. At this point we were met by Jordan McWhirter, head gardener, who very kindly accompanied us for most of our visit and filled us in on much of the garden’s background. Regarded as one of the finest walled gardens on the island, it dates from around 1820. A large yew circle and several mature trees date from then, but otherwise the present design and planting has been continuously evolving since only the mid-1990s.

The immediate stunning vista ahead on entering through this gate is along a grass path between double herbaceous borders leading to an arch opening into the 200yr old yew circle. On both sides a glorious jostling mix of veronicas, stachys, verbenas, phlox, penstemons, cardoons and perovskia provide a gradually fading blur of pastel shades.

Whilst along the south wall there is an extremely long glasshouse used for growing exotic soft fruits and for propagating. Further along the wall is the hot border, famed in late summer for its vibrant mix of deep colours with splashes of yellow – dahlias, alstroemerias, crocosmias, monardas, astilbes, salvias and roses all providing this rich tapestry.

A further mixed border of shrubs and herbaceous planting runs along the west facing wall. An L shaped run of pleached limes adds superb definition to this part of the garden. New exotic plantings are now being tried on the north facing wall….

The remaining upper part of the garden is divided into a series of ‘rooms’ bordered by neatly clipped high beech hedging. So easy to wander and get delightfully lost – in a room with a classical column in the centre surrounded by a series of box balls, or another with a series of small pictorial meadows in jewel- like colours each surrounding a fruit tree, or another with a beautifully crafted central wooden obelisk, or yet another with a grass mound aptly described by garden writer Jane Powers as being like a “vast grassy blancmange”. I can vouch for the tremendous view of the whole garden and magnificent surrounding parkland from the top!

And finally, a pretty double rill runs from the western, uppermost part of the garden down to a small rectangular pond with water lilies.

There is so much to see and love about this beautifully planted and superbly maintained garden. The associated cafes and small artisan shops are both welcoming and excellent, and the Antrim scenery en route is magnificent. What other reasons are needed to make a trip before summer’s end? And if a day trip sounds too much, the Glens of Antrim are as spectacular and beautiful as you’ll find anywhere in which to spend a few days exploring. You might even try staying in one of the stylish Ocean View Pods in the castle grounds!

Seed Saving: A Guide to Annual and Perennial Plants

Seed saving is a timeless and sustainable practice that allows gardeners and conservationists to preserve plant diversity and ensure a continual supply of their favourite plants. This article will delve into the intricacies of saving seeds from plants, with a focus on different types of seed heads, collection methods, and storage tips. We’ll also provide examples of perennials from which seeds can be saved this August.

Types of Seed Heads
Perennial plants produce a variety of seed heads, each requiring different methods for effective seed collection.

Here are the main types:
1. Pods: Plants like lupins and columbines produce seeds in pods. These should be collected once the pods turn brown and start to dry out but before they split open and release the seeds.
2. Capsules: Foxgloves and poppies produce seeds in capsules. Wait until the capsules are dry and brown, then gently shake them to release the seeds.
3. Umbels: Plants such as dill and fennel form umbrella-like clusters of small flowers that turn into seeds. These can be harvested when the seeds darken and begin to dry.
4. Achenes: Coneflowers and sunflowers produce achenes, which are small, dry fruits containing the seed. Harvest when the flower heads dry out and the seeds are easily dislodged.

Collecting Seeds
The timing and method of seed collection are crucial for ensuring viability. Here are the steps for collecting seeds from perennial plants:
1. Timing: Harvest seeds when they are fully mature. This is usually indicated by a change in colour (often to brown or black) and a dry texture.
2. Tools: Use clean scissors or pruners to cut seed heads. Collect in dry weather to prevent mould.
3. Cleaning: Remove chaff (non-seed material) by hand or using screens. For seeds in pods or capsules, gently crush and sift to separate seeds.
4. Drying: Spread seeds on a screen or paper in a warm, dry place. Ensure they are completely dry before storing to prevent mould.
Storing Seeds

Proper storage is essential to maintain seed viability. Follow these guidelines:
1. Containers: Use airtight containers like glass jars or sealed plastic bags to protect seeds from moisture and pests.
2. Environment: Store seeds in a cool, dark, and dry place. A refrigerator is ideal, maintaining a consistent temperature and humidity.
3. Labelling: Clearly label containers with the plant name, variety, and collection date to keep track of your seed inventory.

Seed Viability
Different seeds have varying lifespans. For example
• 1-2 years: Echinacea, lupin
• 3-4 years: Black-eyed Susan, coneflower
• 5+ years: Peony, delphinium

The following guide covers both annual and perennial plants, providing more instructions on how to collect and store seeds. Let’s explore five additional perennials to add to your seed-saving repertoire.

Annuals to Collect Seeds From

1. Marigold (Tagetes spp.)
• When to Collect: When flower heads are fully dried and brown.
• How to Collect: Dry the heads on the plant, then pull them apart to reveal needle-like seeds. Dry thoroughly before storing.
2. Sunflower (Helianthus annuus)
• When to Collect: When the back of the flower head turns brown and seeds are plump.
• How to Collect: Hang the head to dry, rub seeds off, and ensure they dry further before storing.
3. Zinnia (Zinnia spp.)
• When to Collect: When heads are dry and brittle.
• How to Collect: Dry on the plant, pull heads apart to access seeds, and dry seeds on paper towels.
4. Nasturtium (Tropaeolum majus)
• When to Collect: When seeds turn from green to brown.
• How to Collect: Collect seeds naturally as they fall, dry thoroughly before storing.
5. Cosmos (Cosmos spp.)
• When to Collect: When heads are fully dry and brown.
• How to Collect: Dry on the plant, remove long, thin seeds, and allow to air dry.

Perennials to Collect Seeds From
1. Echinacea (Coneflower)
• When to Collect: When heads dry and seeds darken.
• How to Collect: Let heads dry on the plant, then gently shake or rub to release seeds. Dry further if necessary, before storing.
2. Rudbeckia (Black-eyed Susan)
• When to Collect: When flower heads are dry and seeds are easily dislodged.
• How to Collect: Allow heads to dry on the plant, then break apart to collect seeds. Ensure seeds are dry before storing.
3. Lupinus (Lupin)
• When to Collect: When pods turn brown.
• How to Collect: Collect pods before they split open, dry them, and then shell out the seeds. Dry seeds completely before storing.
4. Aquilegia (Columbine)
• When to Collect: When capsules dry out.
• How to Collect: Harvest dried capsules, gently crush them to release seeds, and spread seeds to dry.
5. Digitalis (Foxglove)
• When to Collect: When capsules are brown and dry.
• How to Collect: Collect capsules, shake them to release seeds, and allow seeds to dry further if needed.

General Tips for Seed Saving
• Timing: Collect seeds when they are fully mature to ensure high viability.
• Cleaning: Remove plant debris and chaff to prevent mold and pests.
• Drying: Ensure seeds are completely dry before storing. Spread them on a screen or paper towel in a warm, dry place.
• Storage: Store seeds in airtight containers in a cool, dark, and dry place. Label with the plant name, variety, and collection date.
By saving seeds from both annuals and perennials, you contribute to biodiversity and enjoy a sustainable garden.

Happy seed saving!

Rethinking Pest Management

In the quest for a flourishing garden, understanding the factors that impact plant health and employing sustainable pest management practices are crucial. This comprehensive guide delves into the nature of pests, the detrimental effects of traditional pest control, and the benefits of Integrated Pest Management (IPM). By embracing eco-friendly solutions, gardeners can protect the natural balance of their ecosystems, ensuring robust plant growth and environmental health.

What is a Pest?
A pest is any living organism that causes damage to plants, animals, or the environment. Pests can include plants (weeds), vertebrates, invertebrates, nematodes, and pathogens that cause diseases. However, pests are not the only threat to garden health; abiotic factors like fire, excessive or insufficient water, wind, heat, humidity, cold, nutrient deficiencies, improper pH, high soil salinity, improper pesticide use, soil compaction, and pollution also play significant roles in plant stress and damage.

The Environmental Impact of Traditional Pest Control
Traditional pest control methods often rely on synthetic pesticides, which pose significant environmental risks. These chemicals can persist in the environment, contaminating soil, water, and non-target organisms. For instance, pyrethroids, a common class of synthetic pesticides, are highly toxic to aquatic life, affecting insects, crustaceans, and fish at the bottom of the food chain. Similarly, neonicotinoids, systemic pesticides, infiltrate plant tissues and remain active for extended periods, harming beneficial insects like bees and contaminating soil and water.

The consequences of using such chemicals are far-reaching. They disrupt food webs by killing non-target organisms, reduce biodiversity, and contribute to pesticide resistance. This disruption can cascade through the ecosystem, affecting predators and other species that rely on the targeted pests, ultimately destabilizing the entire garden ecology.

Integrated Pest Management (IPM)
Integrated Pest Management (IPM) is a holistic approach to pest control that emphasizes understanding the ecosystem and using a combination of methods to manage pests sustainably. The IPM process involves five key steps:

Inspection: Regularly monitor plants to identify potential pest issues early.
Identification: Accurately identify pests to understand their life cycles and behavior.
Evaluation: Assess the severity of the pest problem and its impact on the garden.
Action Steps: Implement appropriate control measures, prioritizing eco-friendly solutions.
Monitoring: Continuously monitor the effectiveness of control measures and adjust as necessary.

By focusing on these steps, IPM aims to reduce pest problems through preventive measures and targeted actions, minimizing the need for chemical interventions.

Eco-Friendly Pest Management Solutions
Eco-friendly pest management emphasizes preventive and non-toxic methods to protect plants and promote a healthy garden ecosystem. Here are some effective strategies:

Cultural Controls: Improve garden health by planting the right plant in the right place, using compost to amend soil, feeding plants organically, and mulching to protect soil. These practices create a resilient garden less susceptible to pests.

Mechanical/Physical Controls: Use traps, barriers, and exclusion techniques to physically manage pests. Examples include using netting to protect crops from birds or fencing to keep out larger animals.

Biological Controls: Introduce beneficial organisms that prey on pests. For instance, ladybugs can control aphid populations, and nematodes can target soil-dwelling pests.

Shovel Control: Remove and replace plants that consistently suffer from pest issues or show signs of stress.

Chemical Controls: As a last resort, use eco-friendly or non-toxic pesticides with caution, ensuring they target specific pests without harming beneficial organisms.

Maintaining Natural Balance in the Garden
A balanced garden ecosystem relies on the interactions between various organisms, from plants and insects to birds and microorganisms. Protecting this natural balance is essential for a thriving garden.

Food Webs and Ecological Balance

In a healthy garden, food webs illustrate the complex relationships between predators and prey. For example, aphids (herbivores) feed on plant sap, while ladybugs (predators) consume aphids. Disrupting this balance, such as by using broad-spectrum pesticides, can lead to unintended consequences. Pesticides can kill not only pests but also their natural predators, leading to pest population explosions and further ecological imbalance.

Chemical Transfer in the Food Chain

When synthetic pesticides are used, they can accumulate in the tissues of plants and animals. Predators consuming contaminated prey can suffer from bioaccumulation, where toxic substances build up in their bodies over time. This process can affect higher trophic levels, including birds, mammals, and even humans, posing significant health risks.

Conclusion
By adopting Integrated Pest Management and eco-friendly solutions, gardeners can foster a sustainable and balanced ecosystem. This approach not only protects plant health but also preserves the broader environment, ensuring clean water, healthy soil, and diverse wildlife. Embracing these practices contributes to a resilient garden where nature’s intricate web of life can thrive, creating a bountiful and beautiful space for all to enjoy.

Happy Gardening
