You likely want to grow juicy, tasty tomatoes in your garden every year because you love tomatoes and grow them at home. But is it a good idea to plant tomatoes every year in the same spot? Let’s look at the pros and cons of this idea.
The Case Against Planting Tomatoes in the Same Spot
There are a few key reasons why experts often recommend avoiding planting tomatoes in the same spot each year:
-
Soil-borne diseases Diseases like verticillium wilt fusarium wilt, corky root rot and root-knot nematodes can build up in the soil over time when tomatoes are continually grown in one spot. These nasty pathogens can seriously inhibit tomato plant health and productivity.
-
Nutrient depletion: Tomato plants are heavy feeders that take up lots of nutrients like nitrogen, phosphorus, potassium, and calcium. Growing tomatoes in the same soil year after year can deplete nutrients faster than they can be replaced. This can lead to deficiencies that cause yellowing leaves, poor growth, and low yields.
-
Imbalanced soil microbiome: The community of microbes in soil is essential for plant health. But continually growing the same crops can throw off the diversity and balance of beneficial bacteria, fungi, and other microorganisms in the soil.
The Case For Planting Tomatoes in the Same Spot
While rotating tomatoes is ideal, sometimes gardeners don’t have enough space for a proper rotation So can you successfully plant tomatoes in the same spot year after year? It is possible, but you have to take steps to maintain healthy soil
-
Add compost: Mixing compost into the soil – up to 20% by volume – can prevent many issues. The beneficial microbes in compost can protect against diseases. And compost replenishes nutrients that tomatoes remove from the soil.
-
Cover the soil with clear plastic during hot, sunny weather to expose it to the sun and kill soil pathogens. Do this before planting tomatoes to “reset” the soil.
-
Use resistant varieties: Choose tomato varieties labeled as V, F, N, or T, meaning they are resistant to verticillium wilt, fusarium wilt, nematodes, and tobacco mosaic virus.
-
When you can, rotate your crops. If you have room, plant nitrogen-fixing plants like beans or peas after the tomatoes to give the soil nutrients again. And wait one to three years before moving the tomatoes back to the same spot.
-
Add organic fertilizers: Add organic fertilizers like fish emulsion, compost, worm castings, and so on to your soil. to provide nutrients that tomatoes remove from the soil.
So with the right soil care and management, it is possible to successfully plant tomatoes in the same location for a few consecutive years. But a proper rotation is still ideal if space allows. Listen to your plants – if you see signs of disease or nutrient deficiencies, it’s time to move those tomatoes to a new home next season!
Frequently Asked Questions about Planting Tomatoes in the Same Spot
Here are answers to some common questions about repeatedly growing tomatoes in one location:
How many years in a row can you plant tomatoes in the same spot?
Most experts recommend rotating tomato plants to a new spot every 2-3 years. Planting in the same spot 3 years in a row is possible with careful soil management. Any longer than that, and disease risk increases.
Should you rotate tomato varieties instead of location?
Rotating varieties is not an effective replacement for rotating locations. Different tomato varieties are still susceptible to the same soil-borne diseases. It’s best to move plants to a new spot.
What are crop rotation best practices for tomatoes?
Ideally, follow tomatoes with peas, beans, or other nitrogen-fixing plants. Avoid planting heavy feeding crops like broccoli or cauliflower after tomatoes. Let the soil rest and grow cover crops or grass before rotating tomatoes back.
If tomato plants are showing signs of disease, can you plant tomatoes again in 3 years?
If plants show definite signs of soil-borne diseases, do NOT plant tomatoes or related crops like potatoes, peppers, or eggplant in that spot for at least 5 years, longer if possible. Solarize the soil and start over with clean soil or containers.
Is adding more compost enough to plant tomatoes in the same spot each year?
While compost is beneficial, adding compost alone is generally not enough to allow growing tomatoes in the exact same spot indefinitely. Compost helps but should be combined with solarization, rotation, resistant varieties, etc.
Conclusion
Rotating tomato planting locations every 2-3 years is a best practice to avoid depleting soils and building up diseases. But with careful soil management, it is possible to bend the rules and grow tomatoes in the same spot for a few consecutive years. Focus on replenishing nutrients, fostering beneficial microbes, solarizing, and using resistant varieties. Listen to your plants and be ready to rotate if they show signs of distress. With a little love for your soil, you can enjoy homegrown tomatoes in the same spot while you work on rotating them to new homes.
Why do you need plant supports?
Putting supports in the ground at this point can hurt the plants or roots, even if you do it as soon as the seedling is planted. You will most likely compact the soil around the roots as you are clomping around too! This stunts the tomato plants growth as it makes it harder for the plant to access water and nutrients.
If you wait to add support until the plant is larger – and really looks like it needs support – then you risk wind damage from plants falling over and branches breaking off.
You can drive bamboo canes into the ground or use planters that come with built-in supports, like the Climbing tomato planter, which has a frame, or the Tomato Patio Planters, which have pockets for canes to hold them in place and keep your plant raised.
If you really want to help your tomatoes grow, the Tomato Crop Booster Frame is great for both pots and the ground. It has support bars that can be edged up as the plant grows and support the heavy branches to give an increased yield.
Planting in the same place and not practicing crop rotation can cause problems. Many diseases live in the soil so planting the same crop in the same place can cause re-infection. Added to this, tomato plants are heavy feeders and heavily deplete the resources from the soil so any area of the garden where tomatoes have been grown needs to recover.
The main tomato diseases are blossom-end rot and tomato blight, both the result of soil problems. Blossom rot is caused by a deficiency of calcium in the soil. And blight spores can stay in the soil and destroy crops for multiple years.
Rotating where you plant the crops in your vegetable garden can help reduce the effects of diseases.
As a rule of thumb, only return tomatoes to the same spot every 4 years.
How deep to plant tomatoes
Dig the hole as deep as needed to accommodate the root ball and most of the stem – around 20-25cm (8-10″). Loosen the roots a little and then drop the seedling in the hole and fill with soil mixed with good quality compost.
This is a very common tomato planting mistake. Tomato plants are large and heavy, especially when they are cropping. So plant support will be needed. And they need to be put in before the plant. Instead, people leave it after the plant is in or even worse, until the plant is out of control.
