Tips For Growing Tomatoes In Containers

Tomatoes are a great addition to any salad or macaroni dish. We don’t all have large backyards to grow our tomatoes, so we often opt for the alternative: growing our tomatoes in containers.

Container growing isn’t complex, but small mistakes could be fatal to your plants. Luckily, there are a few tips and tricks that you can follow to ensure your tomatoes are healthy. 

  • Pot Size: Tomatoes like their personal space since they have rather wide-spreading roots. The pot or container you choose should have enough room for the roots to grow fully. 
  • If the pot isn’t large enough, the soil will retain too much moisture. Excess moisture can cause the roots to rot, which could be detrimental to the health of your tomatoes. 
  • Keep The Leaves Dry: Small drops of moisture that accumulate on the leaves of your plant can cause some issues. Fungal growth on tomato leaves is a severe issue you don’t want to face.
  • Small Tomato Varieties: Stick to the smaller types when choosing tomatoes to grow. Only some tomato varieties are suited for small containers and will grow to their full potential. 

  • There’s a wide variety of container tomatoes that you can choose from, including Roma, cherry, and grape tomatoes. These varieties may be small, but they carry a lot of fruit. 
  • Potting Mix: You can make your own soil mix by sourcing the internet and local nurseries for a tomato potting mix recipe. There are also ready-made options available that you add to your containers. 
  • The right mix should have the perfect balance of organic and inorganic materials. Some additions to your mix can include peat moss, sand, compost, and vermiculite.
  • Drainage Holes: Tomatoes do best when planted in containers with large drainage holes. Poor drainage can cause root rot and other problems. 
  • Support: Tomato plants grow high and carry heavy fruits. If they don’t have sufficient support, the stems will start to lean towards one side. Provide some support for your plants by using a stick or trellis. 

The Best Potting Soil For Tomatoes In Containers

Tomato plants are picky when it comes to their soil requirements. Someone at your local plant nursery should be able to advise you on the best mix and soil additives for tomatoes. 

There are some conditions that the perfect soil should meet. The best potting soil for tomatoes in containers should possess the following qualities: 

  • Loose and Airy: Tomatoes have a lot of roots that need fresh air. The nutrients need to reach the roots freely, and the water should drain quickly. 
  • Water Retention: You should water your tomatoes every day. The soil should be able to hold some water, but it needs to drain fast enough, so it’s slightly dry when the next watering session takes place. 
  • Potassium and Phosphorus: All plants need minerals and nutrients to thrive. The best soil for tomato plants contains enough potassium, phosphorus, and other necessary minerals.

  • pH Level: Tomatoes need a slightly acidic potting soil mix. An ideal pH level is between 6.2 and 6.8. They are hardy to any pH level between 5.5 and 7.5. 
  • Clay Content: Clay can make a potting mix too hard and tight. Opt for a tomato soil mix with little to no clay because it causes too much water retention. 
  • Sunlight: Tomatoes don’t like shade, and they thrive in well-lit areas. Your plants need at least 8 hours of indirect sunlight daily.
