April (to return to May, click on the iris to the right).

Ensure vegetable and flower seedlings are pricked out before they get too leggy; they can then be potted on individually as soon as they are large enough. As it gets warmer make sure young plants have adequate moisture, especially under glass; check seedlings daily as they dry out very quickly.

Apple blossom

As daffodils fade, remove both the flower & the seed growing behind it, so nutrients are not wasted on producing seed. Do not cut back or tie up the leaves, as they are essential to feed the bulbs for next year. Where naturalised in grass, leave at least 6 weeks after flowering before mowing. Also apply a high-potassium liquid feed, such as tomato fertiliser, after flowering, but before the leaves start to yellow.

It’s better to put supports for taller perennials in place now; the plants can then grow through them, masking the supports. Try criss-crossing strings between canes. Newly cut hazel or willow shoots woven together can make attractive supports.

Now you still have time to plant asparagus crowns in well prepared soil. Asparagus is not difficult to grow and will provide you with fresh spears through late spring/early summer for many years to come.

Continue to deadhead winter-flowering pansies and other winter bedding. Pansies will carry on into the spring and even to early summer, if attended to frequently.

Feed roses and shrubs to give them a good start to the new growth season.

Tie in climbing and rambling roses. Bringing main stems down towards the horizontal will encourage the formation of flowering side shoots. For roses growing up a column, spiral main stems around it.

Top up pots & tubs with fresh compost. If there is not much room, remove old compost and replace with new to a depth of 5cm (2in). Pot on plants showing signs of being pot-bound, checking whether they are indeed pot-bound or perhaps suffering from some other problem, such as vine weevil.

Sow new lawns or over-seed dead patches from mid-April to early May. If the soil is very wet or cold, delay until the weather improves. Prepare the ground by cultivating, levelling and lightly firming.
