When pruning perennials some plants benefit from having their flowering shoots thinned out. Although this results in fewer blooms, they are larger and of better quality.

Delphiniums, lupins and phlox all benefit from this process. Divide herbaceous perennials when they are too large for their allotted space, are flowering poorly or have lost their shape.

Bamboos and clumps of bulbs or rhizomes can be divided in the same way. When transplanting the divisions make sure they have roots, shoots, and are given adequate water to settle into their new positions.

Sweet Peas

Sweet peas can be sown outside this month. Plant out autumn-sown sweet peas that have been raised in pots, and prepare your wigwam supports for them to climb, using a light twine to tie the plants in.

If you started sowing early in March, or even February, you may have modules of young hardy annuals now ready for planting out.

Hanging Baskets

Towards the end of the month, in mild areas, you may be able to plant up hanging baskets for the summer. When planting hanging baskets use slow-release fertiliser and water-retaining gel.

April jobs

Spring is finally in evidence as daffodils and flowering trees start to bloom.

Expect the inevitable April showers this month but with sunny days too, when you can turn your attention to the lawn. It is an exciting month, with indoor-sown seeds well into growth, and also time to start sowing outdoors. Just watch out for frosts.
