How To Care For Indeterminate Tomatoes

If you only plant one fruit or vegetable this year, make it a tomato! Most gardeners adore their tomato plants, and many of them cultivate multiple types at once.

Growing tomatoes, which range from sweet, snackable cherry tomatoes to large, juicy Beefeaters, could be the most satisfying plant you cultivate this year.

There are several tomato types to choose from that might be intimidating. The duration of your growing season is among the first things to think about.

Early ripening is a characteristic of determinate tomato cultivars. Indeterminate tomato varieties have a longer growing season and can provide fruit till frost.

The tomato you choose will also be determined by how you want to use it. If you plan on canning, choose a determinate variety that ripens at the same time every year.

An indeterminate tomato is great if you want fruit throughout the growing season.

Indeterminate tomatoes are enormous, robust yielders that bear fruit until frost, so they’re ideal if you want nonstop tomato activity but are willing to wait.

Because the fruit becomes heavy and weighs down the plant, these kinds must be staked to maintain the plants erect.

You’ll also have to pinch back the plant to compel it to concentrate on fruit production rather than leaves and stems.

To squeeze, check for fresh growth between the stalk and the mature stems along the main stalk. Just pinch off any new stems or leaves that emerge from the stalk.

Indeterminate types, which include most heirloom tomatoes, produce larger tomatoes. Notable indeterminate types include Beefmaster, Sweet Million, and Early Girl.

How To Care For Indeterminate Tomatoes

The following are various ways to care for indeterminate tomatoes:


Unpruned indeterminate tomatoes frequently produce fewer fruits that are smaller in size.

This is because the plant is constantly producing new vines, using less energy to produce the real tomatoes.

Pruning enhances fruit development while also making the plants more controllable and healthier by increasing ventilation and eliminating pest hiding spots.

Pinch off the small limbs that develop at the nook between a leaflet and the stem to trim suckers off indeterminate tomatoes.

Pruning and securing indeterminate tomato plants will be a sustained effort throughout the season, which can be stressful for novices or busy gardeners.


Indeterminate tomatoes want evenly moist soil, which is not the same as wet soil! Too much water will kill their roots or cause them to rot, which is the most dangerous thing a tomato can experience.

To avoid this, ensure that your garden soil drains rapidly enough so that your plant does not sit in a puddle after watering.

If the soil appears to be a touch too heavy, add some peat moss to help with drainage.

If your tomato plant is starting to look lanky, mound earth around the plant’s stalk.

Tomatoes will start growing roots from any part of the stalk that comes into contact with the soil, thus this will only serve to strengthen the plant’s root system and make it more secure.


Tomatoes, including indeterminate tomatoes, are voracious feeders and require fertilization to provide the maximum yields.

They may also be susceptible to a disease known as blossom end rot, which causes black, decaying bases on your tomatoes.

Some people suggest using Epsom salt to avoid blossom end rot, however, this might be deceptive.

Epsom salts can help your tomato plants, but it all depends on the chemistry of your soil. Epsom salts can exacerbate blossom end rot by preventing calcium absorption.

To get a suitable balance of calcium and magnesium in your soil, we suggest using Cal-Max. Start to use this early in the year, because once your plant has blossomed end rot, it’s impossible to cure.

Between organic and synthetic fertilizers, there is no fundamentally wiser choice.

Organic fertilizers are created from plant-based organic material that decomposes and feeds soil over time, but it’s difficult to determine exactly how the nutrients in the bag are broken down.

Synthetic fertilizers are designed to have a perfect balance of nutrients, making it simple and effective to provide the proper nutrients to your tomatoes.

To prevent over-applying, check the packaging instructions for whichever product you buy.

How Do You Prune And Stake Indeterminate Tomatoes?

When your tomato plant hits a height of 10 to 12 inches, start attaching it to the stake. Garden twine, strips of fabric, or even bits of pantyhose can be used to connect your stake.

Up the full length of the main trunk, stake your tomato plant per 8 inches or so.
