What You’ll Learn

Unlike pruning fruit Tree or berry bushes , pruning tomatoes is entirely optional .

You will still be able to grow a self-aggrandising old crop if you save the pruners for other oeuvre . But it can make a large difference in the size of it , timbre , and quantity of your yield .

Which Tomatoes Need Pruning?

There aretwo types of tomato plant : determinate and indeterminate .

Determinate type grow to a sure height , and then they stop . Indeterminate plants do n’t have a born stopping point . They ’ll keep growing indefinitely until the end of the time of year .

Theonlytypes that should be clip are undetermined ones . leave behind determinate type alone .

When you buy your industrial plant orreview the seed packet , the ticket or verbal description will narrate you which typecast you have . If it does n’t , be sure to front up this entropy to substantiate what you ’re working with .

Why You Should Prune

In a few words , pruning increase the size and number of fruit on the plant .

Since undetermined types produce and grow , they tend to produce too much foliation and stems .

This increment shades the fruit , reduces air circulation , and takes up some of the energy that could be directed to yield increase .

When you circumscribe the routine of fore and leaves , the plant can redirect its Department of Energy to arise big , juicy fruits .

The improved airflow foreshorten the chances of fungous or bacterial problem as well .

When to Do the Work

There ’s no set meter to start lop . Just keep an eye on the plants . Once you get going to see blossom forming an opening , it ’s sentence to break out the pruning shear .

This normally happens some fourth dimension in mid - June to mid - July , depending on where you experience .

After this first rung , you ’ll need to prune again in two week , and every two week after that until thefruits start turning redorwhatever their mature vividness is .

Prune when the plant life are dry . If it just rain or you incidentally splashed water on the leaves when you were irrigate – something you should essay to nullify – wait until the plant is dry .

How to Prune Tomato Plants

Before we skip over in , we need to define a few important terms :

The main stems are the parts of the plant that spring up up , and that support the lateral branch growth .

The branches come out of these main stems and tend to be small and grow either horizontally or at an angle rather than good .

Suckers grow in between the base and the branches at the joint . These are smaller still , but they will finally develop large enough to produce yield .

The problem is , the chump take up a caboodle of push , and they are n’t enceinte producer . So , let ’s get disembarrass of them !

reduce these suckers off as close to the base as you could .

you could do this using scissor grip or pruners , or just pinch them off with your fingernails . Whichever method you choose , strip your tools between plant with saponaceous pee .

Also , remove any suckers that toss off up at the base of the plant from the roots .

If you leave the job for too long and the sucker grow large , instead of cutting them off entirely , snip a little routine away from the base , allow a few leaves to remain .

This protect the stem from tan after being suddenly exposed .

Do n’t remove more than a third of the foliage at one sentence .

What About Determinate Types?

I hump we say that you should never prune determinate types , but there are a few exceptions .

If a offset breaks or look like it might be diseased , off with its head !

likewise , if you have two fruits growing press up against each other , eliminate one .

Over time , the low-pitched branches might start to turn yellow . Prune these off , too .

You should also remove any sucker that form below the first flower clump .

Otherwise , you could middling much leave determinate types alone . Since the sizing and the general number of tomatoes that will be acquire are built into the plant life ’s genetic social organisation , further pruning will only decoct your harvest .

Some Tomatoes Need a Little More Love

Gardening is all about absorbing new information and changing the means we do things as demand .

If you ’ve been let your indeterminate tomatoes do their thing without trimming , it ’s sentence to throw matter up a picayune . I have no dubiousness you ’ll be happy you did .
