Truss size

Posted by lane5 7 (My Page) on

So what factors influence truss size the most? This year I have several plants (growing in 5 gallon pots) with absolutely huge trusses (at least according to my past experiences). The two in particular are Kosovo and Pink Brandywine. One of the Kosovo trusses has two growing tips eventually coming off it.

This year I'm using Miracle Grow potting mix. I'm also pruning virtually all the suckers to keep them to a single stem. I'm curious what factors (pruning, fertilizer ratios) might impact the number of fruits per truss, and I'm wondering if I'm going to compromise the size/quality too much by letting all the pollinated flowers develop. I hate to lose fruit by thinning the truss, but I also don't want 20 golf ball sized Kosovos that aren't very good. I also assume that the growing tips coming off the truss are going to sap a lot of energy that could go into the fruit.

See the pics. In the first one, that's all one giant truss, including 2 tips marked.

RE: Truss size

Hi Lane -
We experienced the same situation back in the first week of May (huge trusses with growing tips) - with the same questions. I can't address the question as to why we had growing tips (we also prune suckers) but we pruned off the growing tips and took the risk of possible small fruit and let the trusses do their thing.

Here are examples of how the cluster look today. Most of the blossoms set fruit - some of the clusters had 8-12 blossoms. The fruit size appears to be developing fine - but you can make the decision to prune blossoms based on our plants if you like. Based on the size of our fruit - I would recommend that you let them grow.

RE: Truss size

The number of fruits/truss is contolled genetically according to each specific variety.

Not all blossoms on a truss will set fruits, just an internal control.

I never prune suckers , many reasons why I don't, and after growing now about 3,600 different varieties i just let the plants do their own thing.

If I were growing for fruit size for competition, for example, which I don't, I'd leave only a fruit or two on each truss, but that's the only time I'd do that, and as I said, I don't do it.
