Other summer flowering bulbs that can be planted now include anemones, ranunculus and calla lilies. All three plus gladiolas, begonias and dahlias will freeze if left in the ground over winter. They should be dug in the fall in early October and stored in dry vermiculite in a cool, dark location.
Virtually all of these bulbs can be purchased as already growing plants in pots in May. However, the cost will be higher than if you buy them as bulbs.
Late April is also a good time to plant vegetables grown from roots or bulbs such as onion sets and asparagus.
Onions are hardy to frost. Potato tuber sprouts can be damaged by frost, but it takes about three weeks for them to emerge from the soil. So they can be planted in early to mid-May
This is also a good time to plant fruits like strawberries, raspberries, currants and bare-root fruit trees. Bare-root fruit plants are cheaper than potted plants, which will be available later. They also get a better start when the weather and soil are cooler.
