A lot of bulbs are showing this autumn partly to do with the weather and partly because they have not been planted deep enough. Yes add more compost to your container and next year plant at least twice and preferably three times the depth of the bulb. Oh and to answer the second part of your question once the bulb has sprouted it can't pull back into the soil.

Tulips are traditionally left to October/November before planting because they tend to start growing early and are then chopped down by an early frost. I agree with the advice given above.

I have muscari, crocus and little daffs all beginning to sprout. I will heap more compost on, but I suspect they will sort themselves out. They usually do.

Every year our trilliums put their noses up in autumn they survive everything the weather can throw at them and are always fine.

thankyou to all i have planted about 1000 bulbs and i am pleased to hear that they will ok sonia
