Some perennials have such tough, thick roots that your bulbs may not be able to find their way up through them. And even if they can, this method only works well up to a point. The point being when it's time to dig and divide your perennials. Then you'll be cutting into your bulbs at the same time, ruining many of them. You can still do it, if you don't mind the somewhat time consuming task of digging the bulbs out by hand. I'm sure there are more and better ways of handling this than mine, but I try to plant bulbs exactly halfway between perennial clumps in groups, so that they are easier to locate. You can also underplant deciduous shrubs, which aren't dug around so often, with bulbs.

If you don't want to plant all your bulbs in the ground this fall, pot them up. I wouldn't advise you to hold them out of the ground for a whole year. Even the toughest ones will dry up and die. Better to pot them up and sink them, pots and all, into the ground. It will be easy to find them next year that way, and they may even increase for you.

No, it won't work. Sorry, but bulbs are living things, even if they are storage units; they will only last so long without earth, air, and water. They don't last foever!

Pot them up or plant them, and you can take a fork and divide some and put them where you want them when the time comes.

Donnabaskets and Hopflower,
Thank you for setting me straight. Let's hope lavender is one of the perennials that the bulbs can get through. I've got a hillside of lavender planted with bulbs. I'll just wait until next fall to plant more between new perennials.

Thankyou
