I water them one time after about 8 weeks, then wait to see which ones start to grow. If they are not growing by around 12 weeks, I water them again, and move them to either a warm room or put them under my grow lights. I don't have enough grow lights for all of them. Some of them I take to work to be under the office lights. I usually wait until after they bloom to fertilize. And then I either use a mild fertilizer at each watering, or put a slow release granular fertilizer on them. I fertilizer them until around August. If I have bulbs I store in the fridge, I just bring them out any time between 8-12 weeks, a few at a time, pot them up and move to a warm spot. But if they start to leaf out in the fridge, I bring them right out and pot them. Do not put citrus fruit in the fridge if you keep bulbs in there!
