Cut perennials such as Penstemons, Gaura and Verbena Bonariensis down to new shoots on last years growth.

Once tomato seedlings have their first true leaves, plant into individual pots. Handle the seedlings by the leaves and not the stem. Plant them deeply, with the seed leaves resting on the surface of the potting compost.

Trim Lavender, take out old flower stems and shorten shoots by 1″ if not done last autumn.

Late in the month begin sowing under glass crops such as runner beans, pumpkins and squashes to plant out after the last frost in May.

Plant chitted potato tubers this month, starting with first earlies through to main crops at the end of the month.

Apply a spring lawn feed. Use a combined product moss killer, weed killer and fertilizer, use a spreader.

Plant summer flowering bulbs, corms and tuberous plants including Dahlias, Canna and Gladiolus directly into containers and borders at the end of this month.

Renovate overgrown and badly shaped evergreen shrubs this month. Camelllias, Hollies, Euonymus and Laurel tolerate pruning to near ground level in one go. Most other evergreens are best renovated over a few years.

Sow vegetables direct, including beetroots, carrots, Lettuce, Leeks, Radish, Turnips, Spring Onions, Peas and Perpetual spinach.

Apply a layer of mulch to your borders. Use organic matter, such as well rotted manure, garden compost or mature wood chippings. Mulching helps retain moisture, suppress weeds and improve soil texture.
