What kind of soil do glads require ?
Glads do well in a wide variety of soil types. A moderate amount of humus is desirable-however, if you work hay, straw, leaves, manure, etc. into the soil, do it well in advance of planting-to be safe, let us say at least six months. If you’ve grown a good vegetable garden, follow pretty much the same program and you should have excellent results. Glads like a pH of 6.2-6.5.
