Your Garden In July
July is the height of summer and while it’s a beautiful month to enjoy your outdoor space, there’s still plenty to be getting on with to keep things looking their best.
Here are some of the essential jobs to focus on this month:
Deadheading & Cutting Back
Keep your borders looking fresh by regularly deadheading flowering plants like roses, cosmos, and delphiniums. This not only tidies up the display but encourages more blooms well into August.
Cut back early-flowering perennials like hardy geraniums and alchemilla to promote fresh foliage and even a second flush of flowers.
Water Wisely
With longer, warmer days, watering becomes key. Focus your efforts on newly planted trees, shrubs, and anything in pots or containers. Water early in the morning or late in the evening to reduce evaporation and ensure the water reaches the roots where it's needed most.
Consider mulching borders to help lock in moisture and suppress weeds.
Time To Trim
Now’s a great time to give your hedges a light trim to keep them in shape. It’s also the perfect moment to prune wisteria, cutting back whippy green shoots to five or six leaves encourages flower bud formation for next year.
Lavender can be harvested for drying. Cut the stems when the flowers have just opened and hang them upside down in a cool, dark, well-ventilated space to preserve their scent.
Harvest & Enjoy
Make the most of your edible garden - July is a generous month! Pick strawberries, raspberries, courgettes, salad leaves, and herbs regularly to keep them cropping.
Keep an eye on tomatoes, pinching outside shoots and making sure they stay well-fed and watered to avoid blossom end rot.
Support Pollinators
Choose nectar-rich plants like echinacea, verbena bonariensis, and lavender to support bees and butterflies through the warmer months. Allow a few herbs like mint and oregano to flower. Your local pollinators will thank you!

July is a crucial month for gardeners. It is time to start thinking about setting up your garden for autumn as well as ensuring you keep on top of summer maintenance. Here are some essential tasks you should focus on: 1. Plant Autumn Bulbs July is the perfect time to plant autumn-flowering bulbs. These bulbs will add vibrant colours to your garden as summer blooms start to fade. • Nerines: These stunning bulbs are known for their clusters of bright, spider-like flowers that appear in late autumn. They prefer being slightly crowded, so plant them in groups for the best display. • Colchicum (Autumn Crocus): Colchicums bring a burst of color to the garden when many other plants are winding down. Ensure they are planted deep enough, around 4-6 inches, to protect them from late summer heat. • Sternbergia: Known as winter daffodils, Sternbergia bulbs produce bright yellow flowers that can light up a garden in autumn. These bulbs thrive in sunny, well-drained locations. 2. Support Tall Plants and Climbers Summer doesn’t necessarily always mean sunshine! Rainfall and wind can wreak havoc on tall plants and climbers. Ensure they are well-supported to prevent damage. • Tall Perennials: Plants like delphiniums, hollyhocks, and sunflowers can be particularly vulnerable to wind and rain. Use sturdy stakes and ties to support these plants. Place the stakes early in the season and tie the plants loosely to avoid constricting growth. Bamboo canes are an ideal choice for supporting tall perennials. • Climbing Plants: Climbers such as clematis, wisteria, and climbing roses need secure supports to withstand bad weather. Check trellises, arbours, and other supports to make sure they are in good condition. Use soft ties to secure the stems to their supports without damaging them. 3. Keep an Eye Out for Pests Summer gardens can attract a variety of pests that can cause significant damage if not managed promptly. Vigilance and early intervention are key to maintaining a healthy garden. • Common Pests: Look out for pests such as lily beetles, snails, aphids, and vine weevils. Regularly inspect your plants, especially the undersides of leaves, where pests often hide. • Natural Remedies: Encourage beneficial insects like ladybirds and lacewings, which are natural predators of many garden pests. You can also use homemade sprays, such as a mix of water and mild soap, to deter aphids. 4. Watering Proper watering is crucial in July as the summer heat can quickly dry out the soil. Different plants have varying water needs, so it’s important to keep this in mind. • Thirsty Plants: Water plants such as celery, beans, peas, courgettes, pumpkins, and tomatoes regularly. These plants need consistent moisture to produce healthy fruits and vegetables. • Fruit Trees and Bushes: Water fruit trees and bushes deeply. After watering, lay a thick mulch of garden compost around their base to hold in moisture and prevent weeds from competing for water. • Watering Tips: Water early in the morning or late in the evening to minimize evaporation. Use a soaker hose or drip irrigation system to deliver water directly to the root zone, reducing water waste and promoting deep root growth. 5. Deadhead Plants Deadheading is an essential task to keep your garden looking vibrant and to encourage more blooms throughout the summer. • Bedding Plants: Remove spent flowers from bedding plants regularly. This not only keeps the plants looking neat but also prevents them from setting seed, which encourages them to produce more flowers. • Repeat-Flowering Perennials: Deadhead repeat-flowering perennials such as roses and geraniums to stimulate the production of new blooms. Use sharp pruners to make a clean cut just above a healthy leaf or bud. • Containers and Hanging Baskets: Don’t forget to deadhead plants in containers and hanging baskets . By focusing on these tasks in July, you'll not only ensure your garden thrives through the summer but also sets the stage for a beautiful autumn. Happy gardening!
