The small seedlings that appear in the trays are the result of the weather conditions that give them the light and warmth and help them to become stronger. Some hardy annuals can now be sown directly outside in the place you want them to grow for the summer display. Be careful to keep a straight row when you sow so you can be able to distinguish the flowers from the weeds that are also starting their growth period.
You can plant gladioli corms, dahlias tubers and chrysanthemums outside, in groups of one variety for a better display. You can start dividing large and congested clumps of decorative grasses or spreading perennials and you can remove the winter protection from the containers.
You can start the clippings on the new growth of the decorative hedges, doing this for maintenance or to give them a new look by creating topiary. Also remember to prune back the flowering shoots of forsythia as soon as its flowers have faded.
Now is a perfect time for a general fertilization and weed-killing using general fertilizer and mulch of bark or compost. For having good crops this year, give some extra attention to your fruiting trees by helping them with a good fertilizer and spreading mulch of compost around them to conserve soil moisture and keep the weeds down. Plant disease-resistant varieties and protect the rest of the others by spraying them with a systemic fungicide.
Mid spring is the time to start the sowing in the vegetable garden too, sow or plant directly outside: herbs, lettuce, broad beans, onion, peas, salads, potatoes or carrots under cloches.
