I do this by mulching with a layer of shredded leaves. The worms break down the leaves over the summer and make worm casings to feed my bulbs. If I think about it, I'll put some bone meal under the leaves to provide phosphorus. But if I forget, I don't worry about it. So, don't worry.
Experts say gardeners are healthier and live longer than average.
Don't ruin these extra years by worrying about the garden. Enjoy it, smell the flowers and eat the vegetables. Your heart and your loved ones will thank you for it. I always try to get more than I paid for. I just got back from the nursery.
