The seeds you started in Feb/March can be transplanted into the garden this month.
Onions and their relatives can be either transplanted and / or direct sown early on as can lettuce and other hardy greens. Peas, beets, spinach, carrots, turnips and radishes can be direct sown throughout the month. Potatoes can go in mid month. The first week of the month is not too late to start tomatoes, peppers and eggplants planted out in late May. Late April is the time to start cucumbers and squash and melons to be transplanted into the garden a month later. Cabbages, broccoli,kale, etc…can be started inside anytime and direct sown mid-month on.
If you have a cold frame it can be put to good use to move the plants you have started in the house to the frame opening up space to start more tender vegetables and to harden off more cold tolerant vegetables before they are transplanted into the ground.
