Hi everyone;
I want to build a garden over my front lawn that is basically just moss and clover but it has crocus' already planted that come up each spring. I was planning to put a load of topsoil on in a mound in the centre and just start planting as there is not much soil, just 6 inches enough for city regulations for planting a lawn. My question is regarding the crocus. They are well established and I really don't want to move them but I am wondering if they will still come up through the new garden or would that be too deep for them to come up through? really don't want to have to try and dig them all out of the lawn??? will they come up?

Sounds to me like it would be too deep.

So are you planning on covering your whole lawn with topsoil? Planting depth for crocuses is usally 3-4 times the length of the bulbs, but as they are already established they might well come through.

I need dig out my tulips bulb just I'm not sure when do have to wait to ripe or is ok rite after bloom stop ?

A lot of people move bulbs "" in the green"". If you need to get them moved now, then go ahead and move them.
