This Simple $25 Tomato Tool Directs Water Straight to the Roots – So You Use Less and Grow More

A gardener waters tomato plants in raised beds at the base with a metal watering can.

Consistent and focused watering is crucial for the best tomato crop. The hungry plants need lots of regular moisture; otherwise, you can end up with struggling plants and disappointing fruit. If you can direct water where it is needed most, your plants will thrive, and there are solutions available to make your watering more efficient.

Poor watering causes many issues. Your tomato plants can droop, curl leaves, or drop blooms if they get too thirsty. Inconsistent or not enough moisture also leads to splitting fruits or blossom-end rot. No one wants to see any of these when growing tomatoes. To prevent this, these tomato crater root-zone watering rings, available at Amazon, can work wonders.

The easy-to-install watering rings help water reach the roots, rather than sit on the soil, run off, or evaporate, and stop weeds from popping up. And you can use them for both watering and fertilizing tomatoes. I have grown tomatoes for many years, and I think these can be a game-changer for home gardeners. Many purchasers agree and have used these root-zone watering rings for many seasons.

A set of three root-zone watering rings to place around tomato plants. They direct water or liquid feed directly to the roots for healthier plants and better yields.

How a Tomato Crater Root-Zone Watering Ring Helps You Have Strong Plants

The tomato crater root-zone watering rings are super-simple to use and can be installed in seconds. Each ring has a 12-inch diameter and is made of two interlocking pieces.

You can snap them together in place when you plant tomatoes. However, due to the design, there is no reason you can’t easily install them at a later date – perfect if you don’t have them when transplanting tomato seedlings.

They are also strong and UV-resistant for use season after season. And they are suitable for more than just tomatoes. The root-zone watering rings can also be used on other hungry crops, such as peppers, cucumbers, eggplant, squash, and zucchini.

The main selling point of the tomato crater root-zone watering rings is that watering is more efficient. You can use less water, but what you do use is directed exactly where the plant needs it most. You essentially get more from less.

Ensuring your tomato plants receive plenty of regular moisture during the growing season is essential. When plants become too thirsty, they often fail to reach their peak, resulting in a disappointing tomato harvest. Problems like poor fruit production, splitting tomatoes, or blossom-end rot are typically down to inconsistent watering habits.

The tomato crater root-zone watering rings sit on the surface around the plants. You water plants by filling the ring, and that water is delivered efficiently directly to the roots through the slots in the base. The water doesn’t run off away from the plants, sit on the soil and never reach the roots, or quickly evaporate away from the top inches of the soil.

The water is directed to the root zone, and the ring keeps it locked in. You need to water less to get the same benefits. The ring also ensures liquid fertilizer (like this Espoma liquid tomato plant food at Walmart) is efficiently delivered and absorbed by the roots. Your tomato plants will be stronger and can grow more tomatoes.

Your location or setup doesn’t restrict their use. You can use the tomato crater root-zone watering rings wherever your plants are. They can be used for plants both indoors and outdoors. You can also use them if you grow tomatoes in pots or raised beds.

What Shoppers Say About It

Shoppers praise the tomato crater root-zone watering rings for being solid and long-lasting. Indeed, several reviewers have had them for many seasons. This includes one who claims to have had them for a decade and added more to their collection over the years, along with other shoppers who admit to repurchasing extra as they love the results.

‘I've used these for years. Every year I buy more,’ says one positive reviewer. ‘I use them not just for tomatoes, but also for peppers and eggplant.’

They add: ‘When I think my plants need a boost, I use Miracle-Gro, and these craters target the solution at the roots so it slowly drains into the soil. Now when I water or feed, I don't have to worry about washing the soil away from the roots.’

Another happy shopper claims that the product ‘solves almost all’ of their tomato problems, and the watering rings are ‘worth it’. They urge others: ‘Don't grow tomato plants without one of these! Works great!’

The rings are designed to help with watering, and one purchaser admits how they have made a difference to their tomato experience – with positive results.

‘I wanted to try these out since I’m not very diligent at keeping up with the weeding and watering,’ they say. ‘This helps so much that I don’t have to be so attentive. Also, because of the trickle watering system, I think my three tomato plants that have this around them seem healthier and are growing more quickly than the ones I don’t yet have one for.’

Some reviews claim they would have preferred the rings to be deeper and hold more water. Another shopper admits that the watering rings don’t work with his setup. They use drip irrigation and granular fertilizers, and admit they ‘would make a difference’ if he hand-watered plants and used water-soluble fertilizers.

It is worth considering whether your methods are suitable for the tomato crater root-zone watering rings. If you prefer to use granular feeds (like this tomato and vegetable granular plant food at Burpee) through the summer and don’t want to water plants manually, they may not prove practical.

What to Shop

A pair of 64-inch-tall tomato cages made from solid 6-gauge steel to support heavy harvests. The 8-leg design keeps the cage firmly grounded during the season.

A super-concentrated liquid tomato feed with an NPK of 3-8-7. Gardeners should mix two teaspoons into one gallon of water and apply it weekly to tomato plants.

These plant grow rings measure seven inches in diameter and are inserted into the soil around your plants. They direct water and fertilizer directly to the roots.

Late summer is a pivotal time for tomato plants. They will have expended lots of energy to grow tall stems and develop early flowers and fruits – it takes a toll on them.

If you need to revive tired tomato plants in late summer, it is crucial to continue watering deeply and fertilizing them with tomato feed or homemade tomato fertilizer every week or two. You also need to pick ripe tomatoes regularly, as leaving them on the plant diverts energy from the development of younger fruits.
