Frilly
I have KY clay and I had to use lots of organic matter (bags of compost, peat, greensand, gypsum, etc...) and work it into the soil of the beds I was going to plant the 1946 bulbs. I used a shovel to dig out 10 inches deep to make trenches ('the Rita way') for the Darwins and some of the other tulips and 6 inches down for the single lates and others that won't come back.
I topped the beds with wood mulch or aged shredded leaves.
I'll add more compost (I get the bags at the local Worm's Way store) next year when I need to plant daffs and tulips, since I know I'll need it.
The one bed that was the easiest was a smaller one that I topped a ton of bagged compost on last year or earlier this year. It was the softest, most workable and had lots of earthworms!
I even dug some trenches in Nov., when the soil was warm and 'diggable' and planted tulips in Dec. when the ground was frozen and snowy. But that is something I don't want to have to do again. I bought 232 late in Nov. (100 on sale from Brent & Becky).
I want to make sure I order early from now on and get them all planted sometime before Thanksgiving from now on.
