"If we had no winter, the spring would not be so pleasant" - Anne Bradstreet
If you’re still waiting for the ground to warm up you could be cutting back winter shrubs, tidying, weeding and pruning. Large flowering clematis, roses, dogwood, buddleia and willow will all benefit from being cut back. The soil in borders you dug over in the autumn will have benefitted from the heavy frosts and can be worked over with a spade or fork to create a fine tithe, with plenty of compost added ready for planting.
Weather permitting, start transplanting herbaceous plants whose clumps you have separated to gain the healthy young outer growth. Lilies and other summer flowering bulbs can be planted in the ground or containers, and sweet peas can be sown outside. Those you may have sown last autumn should be kept in a sunny position in the greenhouse until they are ready for planting out.
Sow hardy annuals for a continuous display in the summer. Annuals sown in the heated green house will bear you flowers by May. You can succession plant cut flowers for the summer in late March onwards and perennials such as delphiniums and hollyhocks will add more, tall, colour to your border display.
When you’re planting summer flowering bulbs make sure the soil is prepared and allows good drainage so they are not sitting in water and rotting. Plant herbaceous perennials, geraniums, Oriental poppies, Agapanthus to Verbenas and anything from A to Z you fancy in between.
