Information
What kind of location do gladiolus grow in
Try to pick a spot with as near full sunlight as possible-performance will vary indirectly with the amount of shade. Poor performance can be expected with 50% shade. Select a location that provides good drainage.
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.
 treatment
As a precautionary measure a preplanting dip is advisable, a good fungicide, such as captan, mixed with an all purpose garden insecticide will do. Follow directions on the package (bottle) for best results.
