When garden space is at a premium, it’s tempting to try and fit as many plants as possible into a small area. A common question that arises from this is, “can you plant two tomato plants together?” While it might seem like a space-saving hack, the short answer is that it’s not recommended.
Tomatoes are heavy feeders with extensive root systems, and planting them too close together can lead to a host of problems that will ultimately reduce your overall harvest. This guide will explain why proper spacing is crucial and what to do if you find yourself with seedlings that have sprouted together.
Can You Grow 2 Tomato Plants Together in a 5-Gallon Bucket?
A 5-gallon bucket is the absolute minimum size recommended for a single tomato plant, especially for determinate (bush) varieties. Planting two tomato plants in one 5-gallon bucket is strongly discouraged. Here’s why:
- Nutrient Competition: Both plants will be competing for the limited amount of nutrients in the soil, leading to deficiencies and stunted growth for both.
- Root Bound: The roots of both plants will quickly fill the bucket, becoming “root-bound.” This restricts their ability to absorb water and nutrients, stressing the plants.
- Watering Issues: A 5-gallon bucket with two plants will dry out incredibly fast, requiring constant watering to prevent wilting and stress.
For the best results, stick to one tomato plant per 5-gallon bucket.
Can You Plant 3 Tomato Plants Together?
Planting three tomato plants together in a single hole or in very close proximity is also not recommended for the same reasons as planting two together, but the negative effects will be even more pronounced. The increased competition for light, water, and nutrients will likely result in three weak, underperforming plants with a meager harvest.

Can Tomato Plants Be Too Crowded?
Yes, absolutely. Overcrowding is one of the most common mistakes gardeners make, and it can have severe consequences for your tomato plants:
- Increased Disease Risk: Crowded plants have poor air circulation, which creates a humid environment that is ideal for fungal diseases like blight and powdery mildew to thrive and spread.
- Reduced Sunlight: The dense foliage of crowded plants will block sunlight from reaching the lower leaves and ripening fruit, which can lead to a smaller, slower harvest.
- Pest Problems: Pests can easily move from one plant to another in a crowded environment, making infestations harder to control.
- Lower Yield: Due to the intense competition for resources, each plant will produce fewer and smaller tomatoes than if it were given adequate space.
How to Separate Two Tomato Plants
If you have two established tomato plants that have been planted too closely together in the ground, separating them can be risky, especially once they are mature. The root systems will be intertwined, and you are likely to cause significant damage to both plants.
In this situation, the best course of action is often to choose the stronger, healthier-looking plant and carefully prune the other one at the soil level. This will allow the remaining plant to thrive without competition.
Can You Separate Tomato Seedlings?
Yes, separating tomato seedlings is much easier and highly recommended. It is very common for two seeds to germinate in the same pot or cell.
Here’s how to do it safely:
- Water First: Water the seedlings well about an hour before you plan to separate them. This makes the soil easier to work with and reduces stress on the plants.
- Gently Remove: Carefully squeeze the sides of the pot and gently tip the entire soil ball out into your hand.
- Tease Apart the Roots: Gently tease the soil away from the roots and carefully untangle them. It’s okay if a few small roots break, as tomatoes are resilient and will quickly grow new ones.
- Repot Immediately: Have new pots with moist potting mix ready. Immediately plant each seedling into its own pot, burying the stem a little deeper than it was before to encourage a stronger root system.
- Recovery Time: Place the newly potted seedlings in a shady spot for a day or two to recover from the transplant shock before reintroducing them to direct sunlight.
Conclusion
While the idea of planting multiple tomato plants together to save space is appealing, it is a practice that will ultimately lead to disappointment. For a healthy and bountiful harvest, it is crucial to give each tomato plant the space it needs to thrive. Proper spacing ensures good air circulation, adequate sunlight, and access to the water and nutrients each plant needs to produce a delicious crop of homegrown tomatoes. If you find your seedlings have sprouted together, take a few moments to carefully separate them—it’s a small step that will make a big difference in the long run.
