Choosing the right container for growing tomatoes is the key.
- Pot size for growing tomatoes depends upon the variety. You should rather choose a large container; a 12-15 inches deep pot or bucket is sufficient for growing most varieties.
- Avoid taking small pots for growing tomatoes since they get root-bound because of the widespread root system and result in low yield.
- Be sure that your container has sufficient drainage holes to discharge excess water, as it can cause root rot.
- You should avoid using terra cotta pots, as they are heavy and difficult to move.

2. Enough Sunlight
Tomatoes thrive with 6-8 hours of sunlight per day. Find a spot where buildings or other obstacles do not block the sun. Avoid placing the pots close to each other, as enough air circulation is necessary to control fungal diseases.
- Rotate the plant regularly, as it will help in providing sunlight to every part of the plant.
- Tomatoes thrive in moderate temperature and prefer warm conditions.
- Avoid placing immature tomato seedlings, outside, in the full sun.

3. Select Fertilizers Wisely
Use organic fertilizers as they are chemical-free and add sufficient nutrients to the container. Bone meal, soy meal, and blood meal are good as they promote the balance of nutrients such as potassium, nitrogen, and phosphorus.
- You should make sure the soil you are using has no fertilizer already.
- Use fertilizers that are meant for tomatoes such as Espoma.
- All-purpose, slow-release fertilizers work just the same way as well.
- Tomatoes that grow in containers need fertilizers at every growth stage.
- Before using fertilizer, check the nutrient content of your soil. If the soil is balanced or high in nitrogen, then go for fertilizer, which is low in nitrogen and high in phosphorus e.g. 5-10-5 or 5-10-10. Contrary to that, if your soil is low in nitrogen, then use a balanced fertilizer with 8-8-8 or 10-10-10 strength.
