How to grow lathyrus

Discover how easy Lathyrus are to grow. Whether raising sweetly-scented annual sweet peas or cultivating perennial peas, this page will help you get started. When choosing between sweet peas and perennial Lathyrus, the main decision is whether or not scent is important to you. Then work out whether you’d prefer an annual or perennial. There are plenty of colour options too, as well as both climbing and more bushy types.

Most sweet peas (Lathyrus odoratus) are highly scented, so choose these if you love a fragrant garden and sweet-smelling blooms to pick for indoors. Perennial Lathyus are generally unscented but Lord Anson’s blue pea (Lathyrus nervosus) is an exception.

How to grow tulips

Planted as bulbs, tulips provide spring flowers in dazzling colours and flower shapes. Grow them in borders, rock gardens and containers before summer flowers appear. Specialist tulips related to wild species often multiply in gardens.

Flowering in spring, this type are seen growing in gardens and parks as temporary displays of seasonal colour (bedding) in borders and containers. They have large colourful flowers, upright stems and wide strappy leaves. There is a wide range of flower colour to choose from; including white-cream, yellow-orange, blue-purple, red-pink, even greens and dark black-purple. Flower shape adds to this diversity, with single-, double-, lily-flowered, viridiflora, fringed and parrot forms. Different tulip cultivars flower from early to late spring, so careful planning can give a succession of colour before summer flowers begin.

A wide selection of border tulips can be bought as dry bulbs from nurseries and garden centres in autumn. They are sold loose or in labelled packs. Choose firm bulbs, which show no signs of mould. The papery brown skin sometimes falls off, but this won’t affect flowering. Buying around 25 to 50 bulbs for every sq m (yd) of garden you want to plant will ensure a really good flowering display (using 25 or less is possible, it’s just you ideally need to underplant with forget-me-not, pansies, wallflowers or primroses so that it doesn’t look gappy). For containers, around 12 would be enough for a 45cm (18in) wide pot, but you can increase this to 20 bulbs for a fuller display.

If you miss out on buying and planting bulbs in autumn, gardening retail outlets and supermarkets often have bulbs grown in containers available in spring. Ideally buy these before they come into full flower.

Citrus – Gardeners’ World 2022 episode 8

Citrus are not hardy in Britain but can be grown in pots outdoors in summer and brought inside for winter. Of all citrus, most gardeners grow lemons; kumquats are the most cold tolerant; others, like limes and grapefruits, need more warmth. The fragrant flowers can appear all year round, but are especially abundant in late winter. Fruit ripens up to 12 months later, so they often flower and fruit at the same time.

Citrus in pots can be put outdoors in summer, in a sheltered sunny position, but only when temperatures increase, from mid-June until late September. Keep some fleece handy in case of sudden cold nights in early summer. Low temperatures will inhibit flowering and may cause damage or even death.

A minimum winter night temperature of 10°C (50°F) is needed for lemons and limes. Calamondin oranges need a minimum winter night temperature of 13°C (55°F).

Kumquats are unusual citrus, as the fruits are eaten whole – including the skin. Plants are naturally very bushy and highly productive. They can tolerate winter temperatures down to 7°C (45°F) – among the hardiest of all citrus.
