I bought some Gladiolus communis sp. byzantinus on sale. This is my first time trying to grow glads; the depth to plant is listed as 6-10" deep, spacing varies 3-5". What would be the best depth for a silty clay loam with a fragipan at about 10 inches; should I plant them a bit shallower since the clay should keep the stalks more upright than a sandier soil?
I also have voles. Are the corms particularly tasty to voles? If so, what would be options on protection? I already have 2 cats and snakes from the woods working on the problem and don't want to poison them. My property is bordering woods so total eradication is not likely.
