The hot and humid weather has brought on a problem for the cucumbers and squash vines in the garden. Powdery Mildew, a common problem in this area, has attacked the plants causing the leaves to whiten and die. Some gardeners simply do not plant squash any more due to the heartbreak this disease can cause.
Since we are trying to solve these problems organically, we searched for an answer to our problem and found milk. Yes, spraying a 1 part skim milk to 9 parts water on all leaf surfaces once a week (after removing all infected leaves) is supposed to retard the spreadof the disease. Also, increasing air circulation by removing leaves and/or staking the plants should help.
