Sulphate-of-Iron Solution
Sulphate-of-Iron Solution.
This is only used as a winter dressing, and the ingredients are—
Sulphate of iron | 5lb. |
Sulphuric acid | ½lb. |
Boiling water | 1gal. |
Place the sulphate of iron in a wooden vessel, and pour the acid over it with care; then add the water very slowly; when dissolved stir up, and it is ready for use. About 2 gals, required for one acre of vines. After pruning gather up and burn all the prunings. Then paint the vines thoroughly with the mixture while warm. If heavy rains wash the mixture off a day or two after application another dressing must be made to insure success.
