Scion -July 2020

Volume 30, Issue #7 – July 2020

Lynn Cox,
BCMG President

Happy July! Summer is here in its full glory! We’ve been having rain showers which have helped keep our gardens and water bills looking good. The weather people are saying that the great Saharan dust storm (yuck) has tempered our early hurricane season (yea). Harvests are bountiful and blooms are glorious!

And speaking of harvest, check out the new page on our website: Vegetable Gardening. I would like to thank Anne Moss, BCMG, for her idea and work to bring it to fruition.

Enjoy July and stay safe!

July is for Watermelon and Water Conservation

by Anna Vogler, BCMG Water Conservation Coordinator

As we celebrate Independence Day and enjoy the refreshing fruits of summer, let’s remember to keep conservation practices in mind for our gardens and landscapes.

The best practice for watering all parts of our gardens, lawns, and landscapes is to water infrequently but deeply. This method will use our water most efficiently and give our plants, trees, and grass the best chance of survival through the hot summer temperatures. Watering deeply will promote deeper roots in the soil, which will also better insulate these roots from the heat and it will decrease the amount of water lost to evaporation. Allow the water to soak 5-6” into the soil. This can be checked with a long shafted screwdriver. (If the screwdriver sinks easily into the soil 5-6” down, it is sufficiently moistened.) Even if you have rocky soil and it is more difficult to check moisture depth, it is best to water deeply.  Once you know the time or water required, you can adapt your water schedule accordingly. 

Even if rules allow watering every day, it is best to wait until the plants need the water. Infrequent watering allows the soil to dry out enough in between watering, which also allows the plant requirement of oxygen to be supplied to the roots. Watering only for a short time and not allowing the moisture to sink down into the soil is not beneficial at all to the plants, and is a waste of this precious resource.  Over watering is also a waste and not healthy for plant roots.  As with everything, the right balance is important. Checking the soil for the moisture depth is very important and truly the only way we actually know how much water to apply.

If there has been a rain event, adjust your irrigation schedule and only apply more water once the soil has had time to dry out. Remember that plant roots need oxygen as well and they can’t get to the oxygen if they are immersed in water.

It’s also best to water early in the morning as this allows any water on foliage to dry off, reducing the potential for disease. Never water during the day as the heat will evaporate much of the water, reducing what the plants receive and costing you more money.

For more information on irrigation methods, check this Earth-Kind publication on irrigation: .

The Bexar County Master Gardener website has a large number of publications linked in our digital gardening library that can be found here: .  

I hope you all have an enjoyable and safe 4th of July.
