Common tomato growing mistakes to avoid

Sarah Johnson15 years experience

After inspecting dozens of home gardens this week, I noticed a few recurring trends holding tomato plants back. Focus on deep watering, proactive trellising, and consistent pruning. Below are quick diagnostics for the problems I am seeing right now along with the fixes that get plants back on track.

  • Overwatering: Water deeply but less frequently to promote resilient root systems.
  • Late season support: Install cages or stakes while plants are still young so stems are supported before fruit sets.
  • Airflow: Remove crowded suckers and lower leaves to maintain circulation and reduce blight pressure.

How often should I water determinate tomatoes during a heat wave?

Answer: Check soil two inches down each morning. Water deeply when it feels dry and mulch to hold moisture.
