What is Pruning?
Pruning is a simple garden practice where you cut off the “deadweight” from the plant. That includes dead and dried leaves, stems, suckers, and any other parts of the plant that have signs of pest damage.
Don’t worry; pruning will not hurt your plant in any way. Instead, it will allow your plant to grow better. Furthermore, by cutting off the unwanted parts, you will give more space for new buds to grow.
That will further ensure your tomatoes are healthy and make them last for a long time as well.
What are Determinate Tomatoes?
Determinate tomatoes (also known as bush tomatoes) grow until they reach an average height of 3 or 4 ft. One way to identify determinate tomatoes is when the flowers of your plant start to bloom at the tip of its branch. That also means your plant has reached its full height.
Moreover, the fruit of determinate tomatoes starts to ripen at the same time. This trait is especially useful for people who grow tomatoes solely for the purpose of canning them.
Determinate tomatoes also do not take up a lot of space as they normally stop growing once they have reached the optimum height. That makes it a perfect choice for gardeners who are tight on space.
Determinate Tomatoes vs. Indeterminate Tomatoes: What is the Difference?
The main difference between determinate and indeterminate tomatoes is their growth rate and height.
While determinate tomatoes stop growing after reaching a certain height, indeterminate tomatoes continue their growth. That may not seem like a problem first, but when your tomato plant reaches a height of 6 to 20 ft tall, it can be quite overwhelming. However, this height also depends on your plant’s variety.
They tend to keep growing until they get hit with a cold, hard frost. These types of tomatoes are not completely undesirable as some gardeners use them by slicing them for salads.
If you would like to achieve a continuous harvest throughout the year, you might find indeterminate tomatoes a better choice.
How to Prune Determinate Tomatoes
Pruning is the practice of cutting off the suckers at the bottom of the tomato plant. It is done to allow for optimal airflow from the bottom of the plant, which will also help prevent plant diseases.
For determinate tomatoes, the shoots usually stop growing once they have set a new terminal bud. If you accidentally cut off too much of the plant, there is a chance you may have reduced the overall yield.
Usually, you should prune a few suckers at the bottom of the tomato plant (5 or 6) up till the first cluster of flowers. However, the sucker under this first cluster tends to grow an extremely strong shoot.
In fact, this sucker is what will help produce a lot of tomatoes. Therefore, it is best to leave this alone without pruning. However, be sure to remove everything below this shoot.
When Is the Best Time to Prune Determinate Tomatoes?
The best time to start pruning determinate tomatoes is when you can see the first flower cluster blooming. If you are to prune your plant before this, you might not correctly identify which suckers need pruning.
On the other hand, some people might prune it too late. By this time, the suckers have grown huge in size, and by pruning these, you will be creating lesions on the stem. It will further cause more damage to the plant as the lesions can cause infections.
If you ever find yourself in this situation, don’t panic! In order to reduce the chances of pathogen infection, you must let the lesions dry out naturally.
With all this in consideration, the best time to prune your determinate tomatoes is preferably the morning of a bright, sunny day.
Tools Needed to Prune Your Determinate Tomatoes
You do not need to have a wide range of specialized tools to start pruning. You also do not have to be an expert in handling these. That is because all you will be doing is cutting off a few suckers, a couple of dead leaves, and so on.
Most of the time, you can do this with just your hands. However, some people prefer using a few handy tools to keep the plant’s smell away from the hands. If you would like to use tools for pruning, here’s a list of what you will need.
- Micro-tip pruners
- Pruning shears/precision pruners (to cut the suckers, leaves, and stems)
And that’s it! Whichever tool you decide to use, be sure to clean them before you start pruning. This way, you will keep the plants healthy and also finish the process sooner.
