Answer: Moss is a symptom of acidic, compacted soils with too much moisture and too much shade. Improving all or most of these conditions should alleviate the moss problem. Bulbs can become over crowded after a few years and need to be dug and replanted so they have adequate elbow room. You can solve both problems at once. Wait until the foliage of your spring blooming bulbs dies down naturally then dig the bulbs, spread 4-5 inches of compost, aged manure or other organic matter over the entire bed and dig it in to a depth of 8-10 inches. Then level the bed and replant your bulbs, giving each about 4-6" inches of space. Next spring your bulbs will grow beautifully and the bed should not have any moss at all.
Good luck with your garden!
