One of the most common questions we get from our readers is how often to water tomatoes in a raised bed. It’s a valid question since tomatoes are a crop that can be seriously affected by over or under-watering. Today, we’re going to share our secret formula for how often to water tomatoes in a raised bed – so you can make sure your plants get the perfect amount of water!
Growing juicy, vibrant tomatoes is a rewarding experience for any gardener. And raised bed gardens make tomato growing easier and more productive. But knowing how often to water your tomato plants is key to getting a bountiful harvest.
Why Grow Tomatoes in Raised Beds?
Raised beds provide better drainage and warmer soil, which helps tomatoes thrive. The soil in raised beds warms up faster in spring, giving your tomatoes a head start on growing. And the improved drainage prevents fungal diseases.
Raised beds also allow you to fill the bed with high-quality soil, compost, and nutrients to give your tomatoes the best start. Tomatoes are heavy feeders so the enriched soil in a raised bed helps them grow strong and produce lots of fruit.
Finally, raised beds elevate the tomatoes off the ground. This improves air circulation and cuts down on soil borne tomato diseases.
Factors That Determine Water Needs
There are a few key factors that affect how often to water your raised bed tomatoes:
-
** Tomato variety** – Cherry and paste tomatoes need less water than beefsteak types Determinate tomatoes need less water than indeterminate
-
Plant size – Young seedlings need less frequent watering than mature, fruiting plants.
-
Weather – Hot, dry, or windy weather increases water needs.
-
Raised bed type – In-ground beds hold moisture better than above ground beds.
-
Soil – Sandy soils dry out faster than those with more organic matter.
-
Mulch – A thick mulch layer helps retain moisture in the soil.
How Much and How Often to Water
As a general rule, established tomato plants need about 1-2 inches of water per week. But use the finger test to be sure – stick your finger 1-2 inches into the soil and if it’s dry, it’s time to water.
Here are some more specific guidelines:
-
New transplants – Water lightly every day for the first week or two until plants are established.
-
Young plants – Water about 2-3 times a week until blooming begins.
-
Flowering plants – Water 1-2 times per week, aiming for deep watering of about 1 inch total.
-
Fruiting plants – Water 1-2 times per week, providing 1-2 inches of water total.
-
Hot and dry weather – Increase frequency to 2-3 times per week.
-
Mulched beds – Can go 7-10 days between waterings.
-
Self-watering beds – Can go 2 weeks or longer between manual waterings.
-
Sandy soils – Will need more frequent watering than clay soils.
-
Container tomatoes – Require almost daily watering.
Always check soil moisture before watering – don’t follow a fixed schedule. And reduce watering once fruits start ripening to avoid splitting.
Watering Methods
It’s best to water raised bed tomato plants at the base of the stem, not from overhead. Drip irrigation, soaker hoses, or water wands all work well.
Make sure to provide water slowly and deeply – tomatoes have deep roots and need deep moisture. Water until the soil is saturated to a depth of at least 6 inches.
The best time to water is early morning, to allow foliage to dry out during the day. Avoid wetting leaves at night, as this can promote disease.
Providing Consistent Moisture
Uneven watering causes more problems than drought. Use these tips to keep soil moisture steady:
-
Add compost and mulch to help retain moisture.
-
Use drip irrigation on a timer to automate watering.
-
For in-ground beds, consider DIY self-watering options like buried clay pots.
-
Grow determinate varieties which need less water.
-
Use shade cloth to reduce water needs in hot climates.
Proper watering is vital for a big tomato harvest from your raised beds. Check soil frequently, water deeply, and aim for consistent moisture. With good irrigation practices, your tomatoes will thrive.
How much is 1 to 2 inches per week?
You might be asking ‘what does it mean to give my tomatoes an inch or two of water per week’? It’s hard to measure precisely! The best way is to set up a sprinkler to give your tomato plants a direct sprinkle of water for about 15 to 30 minutes per week, depending on your sprinkler head’s output.
Use a drip system
You can set up an automatic drip system to water your tomatoes. It takes some time to set up, but you won’t have to remember to water your plants. You’ll also have the benefit of providing consistent moisture for your tomato plants, which will prevent them from turning mealy.
