Squash and zucchini - succession planting

[hendi_alex]

We use the same approach to squash as we do with cucumbers. Always plant some seeds for replacement plants when the older plants are still young and vigorous. You never know when a problem might take out an older plant, plus even if they stay healthy, the plants will get tired and production will slow. At least that is true in places with hot, humid summers.

I've pulled all of my oldest crookneck plants. Repaced them with these three zucchini which were planted in the middle of the corn rows when the corn was ripening.

Also planted one of the lovely yellow zucchini as a replacement. These are simply beautiful and really add to the color of any dish with zucchini.

So far have only planted one replacement crookneck, as we have had a constant supply for the past couple of months.

I'm happy for some tips on growing zucchini! I've got two plants and have gotten 5 fruits so far, and only one female flower since then (a week?). I was hoping for this mythical zucchini "glut", but it is eluding me so far!

We had a month long cool spell with low bee activity in the early spring. Also, I only had one zucchini to survive the early planting. My squash were very eratic during the first couple of months, very often producing unpollinated fruit that rotted and fell from the plant. That single zucchini didn't produce a single fully pollinated fruit. I finally gave up and yanked it from the ground. So far this younger batch of plants is doing very well and providing a steady stream of zucchini.

We're pretty far north and summer is just getting underway. Zuchinni plants are getting bigger but the regular ones have yellow spotting on the leaves. The yellow variety does not have any spotting-any clues?
