As the warm summer days approach, your garden bursts with life and potential. June is a crucial time for gardeners to ensure their plants thrive throughout the season. With a wide array of tasks to undertake, this article will guide you through the essential activities to prioritise in your garden this June. From watering strategies to pest control and plant maintenance, let’s dive into the June gardening checklist.
Watering and Irrigation:
Check your plants daily and water them when the soil feels dry. Pay particular attention to newly planted fruit trees and shrubs that are still establishing their root systems. To save time and reduce water consumption, consider installing an automated drip irrigation system, especially for larger gardens. This efficient method delivers water directly to the plant’s roots, minimising waste and maximising moisture absorption.
Hardening off Bedding Plants:
Prepare any remaining half-hardy bedding plants for outdoor planting by hardening them off gradually. Move them to a sheltered spot outdoors during the day, gradually exposing them to outdoor conditions. This acclimatisation process helps them adjust to temperature and sunlight variations, ensuring a smoother transition when planted in their final positions.
As the sun intensifies, protect your greenhouse from overheating by using blinds or applying shade paint to the glass. On warm days, open vents and doors to promote air circulation and prevent excessive heat buildup. This careful management creates an optimal growing environment for your greenhouse plants.
Maintaining a weed-free garden is crucial during June. Regularly weed your flower beds and vegetable patches to eliminate competition for water, light, and nutrients. Taking preventative measures now will save you time and effort in the long run, allowing your plants to flourish.

Managing Hardy Annuals:
Thin out crowded drifts of hardy annual plants, giving them room to breathe and grow. Removing excess foliage allows the remaining plants to receive ample sunlight, water, and nutrients, resulting in stronger and more vibrant blooms.
Dividing Bulbs and Tubers:
Lift and divide clumps of Snowdrops, Bluebells, and other bulbous plants as their foliage begins to turn yellow. This process promotes healthier growth and rejuvenates the plants by preventing overcrowding. Replant the divided sections in suitable areas to enhance floral displays in the coming seasons.
Hanging Baskets and Containers:
Harden off and relocate hanging baskets and container plants from the greenhouse to their final outdoor positions. Trim back any excessive growth to encourage bushier and healthier development. By providing adequate space and support, you ensure these vibrant displays become stunning focal points in your garden.
Continue watering your flowering Rhododendrons, utilising rainwater whenever possible. These moisture-loving plants require consistent hydration to maintain their stunning blooms. By watering at the base of the plants, you minimise the risk of fungal diseases.
Pinch out the tips of fuchsia plants to encourage a bushier habit and increase flower production. Regularly removing the growing tips promotes branching and ensures a compact, attractive appearance. The resulting profusion of vibrant flowers will delight both you and visiting pollinators.
Prune and deadhead repeat-flowering Roses to encourage continuous blooming. For non-repeat varieties, consider leaving the seed heads intact to add an elegant touch to your garden. Regular deadheading promotes stronger flowering and prevents energy from being wasted on seed production.
Stake tall perennial plants to protect them from wind damage. This precautionary measure prevents their stems from bending or breaking under the weight of flowers or during summer storms. Use suitable stakes and ties to secure the plants without causing damage.
Training Climbing Plants:
As new shoots emerge, use soft ties to train climbing plants along trellises or supports. This method ensures they grow in the desired direction, preventing tangling and promoting an aesthetically pleasing appearance.
Pruning Evergreen Clematis:
After they finish flowering, prune evergreen Clematis plants. Remove any overcrowded or dead sections to encourage healthy growth. Proper pruning also helps maintain an appealing shape and ensures optimal blooming in the next season.
As potato plants grow, continue to earth them up by drawing soil around the stems. This technique promotes the formation of additional tubers and prevents sunlight from reaching the developing potatoes, which can cause greening and make them inedible.
Raise the blades on your lawn mower during dry spells to reduce stress on the grass. Adequate height helps retain moisture and encourages healthier growth. Keep new lawns well-watered to establish strong root systems, and if necessary, consider reseeding any sparse areas.
The warm weather of June often leads to rapid weed growth in lawns. Apply specific lawn weed killers to tackle unwanted invaders effectively. These targeted treatments help maintain a healthy and weed-free lawn.
Keep your lawn looking lush and green by feeding it with suitable lawn fertiliser. Choose a balanced formula that provides essential nutrients for optimal growth. Follow the manufacturer’s instructions to ensure proper application.
Edging and Maintenance:
Recut lawn edges or install lawn edging to enhance the appearance of your garden and facilitate future maintenance. Well-defined edges create neat boundaries and prevent grass from encroaching onto flower beds and walkways.
Patio Plant Care:
In hot weather, water your patio perennials and hanging baskets thoroughly, ensuring they receive sufficient hydration. Utilise water butts whenever possible to conserve water resources. Additionally, begin feeding your potted plants with a balanced liquid fertiliser every two to four weeks to maintain their health and productivity.
Vigilantly inspect the underside of leaves for aphids, and promptly remove them by hand or use an appropriate insecticide to prevent infestation. Early intervention protects your plants from damage and reduces the likelihood of aphid populations multiplying.
Evergreen Hedge Pruning:
Clip evergreen hedges, such as Privet, Box, and Yew, while they’re actively growing. Regular pruning maintains their shape, density, and overall health. Trim lightly to encourage a dense growth habit and promote strong, vibrant foliage.
Greenhouse Plant Care:
Check your greenhouse plants daily and water them if the soil feels dry. Proper watering is crucial for maintaining optimal growing conditions and preventing stress on your delicate greenhouse specimens.
To keep your compost healthy and aerated, turn the contents of your compost bins every month. This simple task promotes decomposition and helps produce nutrient-rich compost for future use in your garden.
Flowering Shrub Pruning:
Prune any flowering shrubs that have finished blooming. Remove spent flowers and any dead or diseased branches to encourage healthy growth and prepare the shrubs for next year’s display.
Regularly hoe your garden borders to keep weeds at bay. This quick and effective method disrupts weed growth and prevents them from taking over your flower beds. Hoeing also helps to aerate the soil and improve moisture penetration.
Summer Bedding Planting:
Take advantage of the warmer weather and plant out your summer bedding. Whether it’s vibrant annuals or fragrant perennials, introducing new plants adds colour and variety to your garden.
June offers an abundance of gardening tasks to ensure your garden thrives throughout the summer. By following this comprehensive checklist, you can prioritise essential activities such as watering, plant care, pest control, and maintenance. Taking these measures will reward you with a beautiful and flourishing garden, providing a delightful sanctuary for you to enjoy during the long, sun-filled days of summer.
