Onion maggots, thrips
Start seeds indoors in February, for transplanting into the garden later in the spring; or sow directly outdoors from mid April.
Performs well planted in clusters of 4-5. Bend over any flower stalks that start to grow so the plant’s energy goes into building the bulb. Keep a clean garden; thrips live in weeds from previous years.
