The Best Garden Tower® Watering Tips and Tools

closeup of tomatoes growing on a Garden Tower®Water is one of the most important components of gardening—whether it’s a compact vertical vegetable garden or acres of fields, all vegetables need water to survive. Just because water is essential doesn’t mean that you can’t overwater your garden, though. In this blog, we’ll be highlighting our favorite products, such as garden hose filters and water meters, as well as giving you the hottest tips to keep your Garden Tower® thriving this summer.

Keep Your Plants Healthy With Watering Tips and Tricks

Let Your Garden Thrive With Proper Watering

While most towers are watered 2-3x per week with 4-8 gallons of water, there is no exact formula because everything depends on how quickly the plants are growing, temperature, sun exposure, humidity, and wind. There are some signs that will help you gauge whether your garden is underwatered, though:

  • Shriveled leaves
  • Limp stems
  • Dry or flaking leaves
  • Petals or leaves falling off
  • Yellow, white, or brown coloring

Underwatering can come from a variety of sources, not just how little you’re watering. There may be too much evaporation, which can easily be fixed with a layer of mulch or rocks to keep water in the soil. 

Additionally, due to the vertical composition of the Tower, sometimes users may find that one section is significantly more watered or dry than the other. If plants in the top third of the Tower tend to dry out too quickly, increasing the amount of water per watering session by 1-2 gallons will ensure a more thorough, deep watering. On the contrary, if the bottom of your vertical vegetable garden is too moist, try adding an extra day between waterings but compensate for this by adding an additional 1-2 gallons when you do water. When planning your Garden Tower®, it is crucial to your plant’s success that plants requiring a more moist environment are placed closer to the bottom of the Tower and vice versa. 

Additionally, it’s important to remember to water your Tower from the top and let it trickle down, as watering the plant pockets will NOT fully moisten the entire root zone available to your plants. Plants grow their roots towards water, so if you’re not watering the entire column of potting soil, your plants will not develop deep roots that take advantage of the plentiful potting soil and reach the compost column for additional nutrition.  Chronically under-watering or watering only from the pockets can result in stunted plants which will not thrive.  Frequent overwatering is very easy to prevent by keeping an eye on how much nutrient tea is accumulating in the two-gallon drawer in the base of the Tower. Most gardeners target about two gallons per week of nutrient rich water to be recycled to the top of the Tower.  Always measure how many gallons are being applied while watering with some of our helpful products, as you can check the moisture level easier and adjust your watering routine precisely.


Check Water Levels at a Glance

Know When Your Soil Is Dry Before Your Plants Tell You

Garden Tower Project has been using these probes for several years and we highly recommend them.  They do not require batteries, are highly reliable, and long lasting. After two to four years, the internal color-changing wick can be replaced if it gets compromised.
