David's Tips For July
Houseplant of the month
Crassula ovata (Jade Plant)
A much-loved houseplant, the Jade plant is valued for its thick, glossy leaves and sculptural shape. Native to South Africa and Mozambique, it thrives in bright, rocky conditions, storing ample water in its plump leaves and stems. As a houseplant, it brings bold greenery to sunny windowsills and desks.
Otherwise known as the ‘money tree’ or ‘friendship tree’, Crassula ovata is linked with prosperity and luck in Asian cultures. Often given as a gift for new homes or businesses, it is thought to bring positive energy when placed near doorways or shared living spaces.
These succulents suit the warm, bright conditions of July. Place them in a sunny position such as a south or west-facing window. Allow the compost to dry out fully between waterings and avoid soggy roots during hot spells.
To keep the growth compact, pinch out tips or prune leggy stems. Cuttings root easily in compost, making this plant simple to propagate to keep or share. Popular varieties include ‘Hummel’s Sunset’, with golden-edged leaves, and ‘Minor’, a compact form ideal for smaller spaces.
With its easy care habit and steady growth, the Jade plant brings structure and symbolism to the home all year round.
Outdoor plant of the month
Verbena bonariensis
With tall, slender stems topped by clusters of lavender-purple flowers, Verbena bonariensis adds height, movement and colour to any summer border. It’s native to South America and is a magnet for butterflies and bees, offering a long season of nectar from July into autumn.
Its airy form makes it ideal for planting among other perennials without blocking views. It weaves gracefully through beds and borders, adding a light touch of colour without overpowering other plants. The flowers also hold up well in arrangements, making them a great choice for cut flower gardens.
Verbena prefers a sunny, open spot with free-draining soil. Once established, it copes well with dry weather and poor soils. In July, keep newly planted specimens well-watered until roots have settled. Removing spent flowers encourages more blooms and can prolong flowering into early autumn.
Whilst technically a short-lived perennial, Verbena bonariensis often self-seeds in ideal conditions. Seedlings can be lifted and replanted where needed in spring. Leave a few seedheads standing for winter interest and wildlife shelter.
Look out for varieties such as ‘Lollipop’, which stays more compact and is perfect for pots or front-of-border planting. Whether in large drifts or subtle accents, Verbena brings elegant energy to the summer garden.
Gardening job for the month
Deadhead to extend the flowering season
With the garden bursting into full bloom, regular deadheading is a simple but essential task to keep things looking their best. By removing faded flowers, you redirect the plant’s energy away from seed production and back into new growth and more blooms..
In July, focus on fast-growing summer favourites like cosmos, dahlias, marigolds, sweet peas and roses. Most respond with a fresh flush of flowers within days. Bedding plants and hanging basket displays also benefit, maintaining their impact through the busiest months of the season.
Check for aphids on new growth and remove them by hand or with a quick blast of water from a hose. Encourage natural predators like ladybirds by avoiding chemicals and planting pollinator-friendly flowers nearby.
Use clean, sharp pruners or snips and remove the entire faded flower head, including any seed pods or stems below. For multi-flowered spikes like delphiniums or salvias, cut back to a healthy leaf joint to encourage side shoots.
Deadheading is also a good opportunity to check for pests or signs of disease. Removing affected flowers promptly helps prevent problems from spreading and keeps plants in top condition.
Aim to deadhead little and often. Just a few minutes each day can make a big difference. With this quick and rewarding task, you will enjoy longer displays, healthier plants and a garden that stays vibrant well into autumn.
