Re: CULT: Heavying Up Too Light "Soil"

I don't know whether either of the following are of any use to you, but the 
two methods I have used are:

1. before filling the area with soil, line with a thick layer of newspaper, 
and pads of alfalfa hay, about 3" thick. The hay breaks down in a short 
time, and the irises put their roots down into this yummy mix, which retains 
more moisture than the soil above.

2. add 1:6 well rotted mushroom compost, to the soil, and dig in well. This 
is fairly alkaline, so not suitable for all irises.

Cheers, Jan
