Inspired by your guide on turning some lawn area into a productive garden by using the lasagne gardening method, we have tomatoes, squash and zucchini underway. The problem is, my zucchinis have been getting a lot of flowers, but the fruit themselves don't develop past a certain point - the end goes soft and they fall off which is a big disappointment. The weather on the north west coast has been cold and humid, and we've been getting a lot of mildew and mold, could that be the problem? Would appreciate your help!

It's great to hear you've converted some of your lawn into a productive garden. The lasagna method is an excellent choice for building healthy soil.

The zucchini issue you're describing is a frustratingly common one, especially here in the Pacific Northwest, but the good news is that there's a very straightforward solution.

While the mildew is a nuisance, it's not the direct cause. The core of the problem is a lack of pollination. Zucchini plants produce separate male and female flowers, and they rely on pollinators like bees to transfer pollen between them. Our cool, damp weather significantly reduces bee activity, so the female flowers (the ones with the tiny fruit at their base) are being aborted by the plant because they haven't been fertilized.

The solution is to take on the role of the pollinator yourself through a simple technique called hand-pollination. It's highly effective.

Here’s the procedure:

  1. Timing is Key: Perform this in the morning when the flowers are fully open and pollen is most viable.
  2. Identify the Flowers: Locate an open male flower (on a long, thin stem) and an open female flower (which has the small embryonic zucchini at its base).
  3. Collect and Transfer Pollen: Carefully detach a male flower and peel back the petals to expose the pollen-heavy anther. Gently brush this anther against the stigma in the center of the female flower. A small, soft paintbrush can also be used to transfer the pollen.

Once pollinated, the small fruit at the base of the female flower will begin to develop into a full-sized zucchini.

Regarding the mildew, that is a secondary issue caused by the same humid conditions. The best way to manage it is to water the soil directly, keeping the leaves as dry as possible, and ensure the plant has good air circulation.

Implementing this technique should resolve the issue and lead to a successful harvest. Hope this helps!
