How to grow courgettes
Courgette plants are easy to grow and fruit abundantly – expect to pick three or four a week in good weather. These plants like to spread out, so give them about a square metre/yard each, or grow in large containers or growing bags if you’re short of space.
Courgettes are easy to grow from seed. They are best started off indoors in pots, but you can also sow them outdoors in the spot where they are to grow. For earlier crops or in cold regions, sow seeds indoors from mid- to late April at 18–21°C (65–70°F). Sow seeds individually on their side, 1.5cm (½in) deep, in 7.5cm (3in) pots of compost.
In late May or early June, prepare your sowing site by digging in lots of home-made compost or well-rotted manure, to about the depth and width of a spade’s blade. Then sow two or three seeds in the centre, 2.5cm (1in) deep. Cover with a cloche, jar or plastic, and leave the covering in place for two weeks, or as long as possible, after germination. If more than one seed germinates, remove the smaller, weaker seedlings to leave just the strongest one.
Clematis – Gardeners’ World 2022 episode 13
The ‘Queen of Climbers’, clematis produce masses of flowers in a wide variety of shapes and colours. With careful selection, it’s possible to enjoy their blooms throughout the year, and with plants suited to growing on walls and fences, up obelisks and pergolas, into trees, in containers and even in a mixed border, it is easy to see why these versatile plants are one of the most popular in gardens.
Most clematis grow best in a sunny or part-shaded position, but there are plants available to suit any aspect. Consider the conditions in your garden and choose a plant that will thrive there, whether that’s a shady wall or a particularly hot and sunny one.
Clematis is a genus of about 300 species within the buttercup family, Ranunculaceae. Their garden hybrids have been popular among gardeners, beginning with Clematis × jackmanii, a garden standby since 1862; more hybrid cultivars are being produced constantly. They are mainly of Chinese and Japanese origin. Most species are known as clematis in English, while some are also known as traveller’s joy, a name invented for the sole British native, C. vitalba, by the herbalist John Gerard; virgin’s bower for C. terniflora, C. virginiana, and C. viticella; old man’s beard, applied to several with prominent seedheads; leather flower for those with fleshy petals; or vase vine for the North American Clematis viorna.
Growing irises is easy and provides some of the earliest blooms in the garden; later-flowering varieties compliment summer-flowering plants. Whether in containers or in the open garden, they are hardy and provide colour year after year.
Growing irises from bulbs is easy and provides some of the earliest blooms in the garden; later flowering varieties compliment summer flowering plants. Whether in containers or in the open garden, they are hardy and provide colour year after year.
Early flowerers are diminutive plants with yellow, blue or white flowers. Summer varieties can have flowers in all colours. Unlike other irises, the bulbs have narrow, grassy leaves. These irises grow in any soil that drains freely, in full sun at flowering time. Early types do well under deciduous trees and among shrubs that provide shelter in summer.
