Pictures 1 and 2 are a view of the plants showing the new growth on the LT and roots on RT. After a section produces veggies I cut back all the leaves pushing the plant energy towards new growth. Leave a few leaves around new growth to provide the shade it needs.
Pictures 3 and 4 continue on the same line. Showing the old places that produced veggies and how the new growth keeps going. Picture 4 with my hand in it shows where the root decided to produce 2 new growth sections. Zucchini plants will develop multiple new growth sections at the same time. Currently I have 1 plant that has started 5 new growth sections. Again prune off leaves that do not have veggies growing underneath.
Pictures 5-7 show new growth sections; roots are behind the new growth. Picture 5 shows a close up of new growth w/ baby zucchinis (3) and new flowers and leaves growing. Picture 6 shows new growth from previous week with a full grown zucchini. As part of pruning if you see smaller leaves that when grown will stunt the growth of a zucchini go ahead and prune it. You can see in this picture that I pruned a few things around this zucchini to let it grow. Picture 7 shows new growth of squash. New growth for both plants grows upward until it reaches a certain size then lays back down on the ground.
This may seem like a lot of information or even a lot of hard work but it's not really. We ended up doubling the amount of produce we got this year. We had neighbors who's plants started producing the same week as ours and we are still going where theirs has ended.
