STOP WATERING YOUR TOMATOES!!!

Since time immemorial, it has been almost impossible to water tomatoes correctly.  Water too little, and you will get very poor growth.  Water too much, and your tomatoes will split.  Other diseases, like blossom end rot, are also due to problems with watering.  It seems almost impossible to get tomatoes consistent amounts of water, regardless of rainfall or drought.

Raised beds somewhat solved the problem of overwatering - especially after heavy rains.  The "Mel's Mix" of 1/3 vermiculite, 1/3 peat moss, and 1/3 compost advocated by the late, great Mel Bartholomew in his book All New Square Foot Gardening works well to hold moisture.  Also, because this soil mix is only used in raised beds, water will not stand and suffocate tomato roots.  The problem with raised beds, even with Mel's Mix, is that with the limited depth of soil, the soil dries out very quickly - potentially in just one day in hot, windy, dry climates.  This means a great deal of work for the average gardener - with manual watering required every single day.  Of course, an irrigation system could be set up - but this is very expensive, time consuming, and isn't really worth it for just a few tomato plants.

So, the problem of how to water tomatoes remained, until, that is, of the invention of a device called the Groasis Waterboxx PlantCocoon, or Waterboxx for short.  The Waterboxx was originally designed by a Dutch lily and tulip breeder, Pieter Hoff, to grow trees in very dry areas without electricity or running water.  It soon became evident, however, that the Waterboxx would work superbly for growing tomatoes.

The Waterboxx has since been used throughout the world to grow tomatoes.  Here in the U.S., we have seen that it is possible to grow tomatoes in a profound drought without any water added after planting, as Waterboxx enthusiast Tony Palumbo discovered in 2015 in Sacramento County, California.  As you can see below - the Waterboxx planted tomato there did excellent without any watering after planting, even in 106 degree heat, and with less than a quarter inch of rain the entire growing season.  

A summer's growth of a Waterboxx tomato - all without any watering after Waterboxx set up - even with less than 0.25 inches of rain and maximum temperatures of 106 degrees!  This single Waterboxx tomato grew 56 tomatoes.

In Sacramento County, 56 tomatoes were harvested from this one plant without any watering after planting.   This number of tomatoes is more than enough for most people -but if you want more for canning or making sauce, you can insert extra wicks into the Waterboxx and get an even greater yield (with some extra watering).   In Southern California (Hemet), 981 Juliet (Roma style) tomatoes were harvested from a single Waterboxx (with extra wicks) with just 6 times of watering all summer.

In Indiana, where we are based, we have had over 1500 cherry tomatoes grow with a single Waterboxx, all without any watering after planting.  Even though cherry tomatoes are known for splitting, we had less than 1% split due to the consistent moisture provided by the Waterboxx, even after heavy rains.

Roma and cherry tomatoes planted in a Waterboxx - the Roma plant was destroyed in a storm but the cherry tomato plant went on to produce over 1500 tomatoes - all without any watering after planting!

We have been gardening since childhood and the Waterboxx is the best device or method we have seen for growing tomatoes.  We believe so strongly in the potential of the Waterboxx, that we created a company to promote and sell it here in the U.S. - Dew Harvest LLC at www.dewharvest.com.  If you are interested in trying out the Waterboxx, especially if you live in a drier climate (like the Southwest), you can visit our buy page and buy the Waterboxx here.

We would love to read your comments below.  Happy planting!
