We've been down in Auckland for a couple of days and before I left I gave the plants in the greenhouse a good water and left it open so my little ones wouldn't cook.
Was so excited to come back and check on them and to my horror it turns out we have powedery mildew starting on the cucumbers. I don't think the humidity and lack of airflow in the greenhouse helps.
Luckily it's only just started. The most infected leaves have been removed and disposed of and then the plants given a good copper spray last night. Today I planted some out as I figure the air will do them some good. Fingers crossed we have this under control. Haven and I do love our cucumbers.
