I have recently bought a house and I was planning a small tulip patch. I dug my ideal area on the backyard, 6" deep, just to discover I had chosen the spot where an old foundation had been covered with soil :(. It is right at the 6" depth that the tulips need to be planted at.
Can I plant them on top of this concrete foundation, maybe less deep (5" or so) with a bit of soil under them (1")? Or should I just get over it and choose a different spot?
How about daffodils?
