Growing Tomatoes in Large Pots

Large pots and containers have several advantages over grow bags or planting directly into the ground.

  • They can be moved easily.
  • Great for bush varieties.
  • Plants can trail over the side without reaching the ground.
  • It is more difficult for slugs to hide.
  • It is easier to plant a support in a deep pot than a grow bag.

Three Large Pots

However, there are a few disadvantages with large pots and some containers.

  • Pots can be blown over by the wind.
  • They can break easily – especially if plastic.
  • It is more expensive to buy pots than grow bags.

Tips For Using Pots

Adding sand to the compost will improve drainage and make the pot heavier and therefore less likely to be blown over on a windy day. You could also put a large stone or brick at the bottom.

Gravel or stones at the bottom of large pots helps drainage. However, if water drains away too quickly, it may be difficult to keep all the compost moist throughout.

Add perlite, vermiculite or gel to the compost to help retain moisture and prevent compost from drying-out too quickly.
