Watering tomatoes during the planting process is an important step in helping them adjust to the outdoor garden. When you know how much water newly-planted tomatoes need and when, you’ll help them get established and begin producing lots of sweet, healthy fruit.
About an hour before planting tomatoes in the garden, water seedlings deeply.
Monitor plants at least once, preferably twice, daily. Give each plant at least a quart of water each day, more if the weather is especially warm.
Tomatoes that have been in the ground for 10-14 days need consistent watering but also need to be strengthened. Give them 1-to-3 inches over 10 days or even 2 weeks – closer to 1 inch if the weather is cool, closer to 3 inches if temperatures are hot. The touch of extra stress on the plant pushes it to produce fruit.
Established plants get 1-3 inches a week of water (including rainwater) – closer to 1 inch if the weather is cool, closer to 3 inches if temperatures are hot. On average, each plant should get 2 gallons of water a week.
Tomatoes need water more than once a week. Don’t give them 1-3 inches all at once. They’ll dry up and get stressed in between waterings. Don’t water a half inch every day. They’ll get lazy and develop shallow root systems. Instead, provide water every 3-4 days until fruit emerges. Keep watering patterns consistent to prevent cracking, blossom end rot, and poor production – and to produce healthy tomatoes.
