GIANT plants, but almost no veggies? Need pollination?

GIANT plants, but almost no veggies? Need pollination?

Post  npars on 8/4/2011, 2:37 pm

I planted 2 tomato plants, and 1 zucchini and 2 cucumbers. The tomato plants are just gigantic about the biggest I've ever seen - about 6 feet tall and 2-3 feet across, and very thick with branches and leaves. However, there are almost no tomatoes! I think I found only about 5 on each plant. (I had one extra tomato plant that I just stuck in a planter in regular soil - and though it's a sparse, spindly thing, it has more tomatoes than the super large plants.)

The zucchini is also looking great, and has a few flowers (a few of which have fallen off now), but has no sign of any zucchinis on it. The cucumber plant has maybe 1 teeny tiny one on it.

Am I not doing something that I should be? Are the plants getting pollinated, or am I supposed to do something with that myself? Or should I have been thinning out the tomatoes so that more energy goes into the fruit and not into leaves?

I have fairly fine bird netting (4' high) around the garden too to keep out animals (but the top is mostly open). Might this keeping out bees and bugs needed for pollination?

sounds like you soil has to much nitrogen.
or not enough phosphorus.

I've heard that you should keep your tomatoes pruned back so that there's just one main vine, and then cut off all the suckers. That way it spends its energy on making tomatoes rather than leaves. However, I'm pretty sure that same advice doesn't apply to zucchini or cucumbers!

So I think I have to agree with Jcpen about the overabundance of nitrogen. The weather might also have something to do with it. What's your weather like? And can I ask where up north you are? It might just be too early for you Smile

Thanks for the answers so far. I hadn't thought of too much nitrogen as a culprit. I used a good bit of composted manure in the soil mix, so maybe I had too much of that? I'm up in Wisconsin, so it may be a bit early to have ripe tomatoes, but there should at least be lots of green ones by now.

If there is too much nitrogen in the soil, how does one counteract that?

Well if it was me, knowing that we in the north have about 6 weeks until frost, I would stress the plants a bit. Lop off the top growing tip and lop off a bunch of lowest leaf branches. Be careful and double check that what you want to cut off has no flower buds. This should send a signal to the plant that conditions are not good (stress) and it better hurry up and reproduce. They should put out flowers pretty quickly.
This is just my opinion. Welcome to the Forum!
