Tasks for spring and the month of April
It’s time to plant your gladioli and acidantheras. Also a good time to thin the roots of any herbaceous perennials. Sow hardy annuals in situ and prick off those sown earlier. Remove any dead flowers from narcissus and any other spring flowers.
As the weather is now milder, sow lawn seed, but make sure you use protective netting to deter the birds. Mow your lawn at a medium height, making sure your mower has been cleaned and that the blades are sharp.
Have a general tidy up and remove all dead leaves and debris from your borders.
Apply mulch to roses and give lavender a final trimming and don’t be afraid to be brutal, as this encourages much more vigorous growth, same applies to rosemary.
Remove any winter-flowering heathers, solanums and remove dead flowers from rhododendrons.
Prune early flowering shrubs such as ribes, forsythia, Philadelphus and Weigela. If the threat of frost has passed, it’s time to remove all dead blooms from Hydrangeas. You will soon be able to sow foxgloves, wallflowers and sweet William.
Prune newly planted bush fruits. Use nets to protect flowers on fruit trees just in case we experience a frost. If the weather is dry then water the newly planted fruits and spray against pests and diseases (do not spray if the trees are in full flower).
If you have a greenhouse then sow seeds of outdoor tomatoes, melon and courgettes. You should space out growing plants and watch for pests and diseases. Bedding plants should be moved into cold frames.
If you have a vegetable patch then you should start successional sowing of radish, lettuce, peas and beans. You should also sow your main crop of carrots.
Cauliflower and calabrese (broccoli) should be planted out raised in cold frames. You can plant late potatoes earth up the early ones.
