The experiment: to grow tomatoes on my balcony during a Sydney winter using seeds scraped from a store-bought tomato. (Although we’re well into spring now.)
Oh dear, things are looking worrying. Last evening it was very windy so I moved the pots to the balcony floor, which meant that this morning I was able to look down on the leaves. Powdery mildew is rampant!
So off I went to Google again to see what is suggested. And would you believe it — milk! Diluted 1:4 or 1:5, and sprayed on the leaves weekly. So I have diligently done so. As for the pot that is being “watered” with milk, I can’t say that those two plants look any better or any worse than the three plants getting more conventional fertiliser. It’s the middle pot in the photo of all three pots at the top.
Now the race is on: will any tomato ripen and be edible before all the plants die from the bottom up?
