HOT HOT HOT

 

from https://weather.com/  7/27/21


Dear Central Virginians,

That recent reprieve from the hot weather was great, but, sadly, it is not going to last. More days in the 90's are ahead, plus limited chance for rain.  

This is a "do what I say..." post. For a number of years, I have occasionally used soaker hoses.  But, because I was leaving a fairly newly planted vegetable garden for over 3 weeks in June (what was I thinking!??!?) I set up a series of soaker hoses on a timer and I am glad I did! For shorter vacations, I often asked kind neighbors and friends to water my garden by turning on sprinklers for a couple hours every few days.  I was never gone for long, so did not worry about the water wastage and inefficiency of this watering. I just needed a way for friends to do this easily and it was sort of ok.  And I was too lazy to set up soakers and timers. BUT I KNEW BETTER!  High, overhead sprinkling wastes up to 90% of the water to evaporation. The higher the arc of the spray and the more fine the spray, the greater the waste. Try an experiment: set up an overhead sprinkler for an hour, then dig into the soil after it turns off.  You will see that the water did not penetrate far.  This encourages shallow roots which cannot support healthy plants.

My setup is not the greatest. I have hoses that cross the brick paths between the beds, that wasted water partly reclaimed by buckets to be used later.  I need a better solution.  But my plants are lush and healthier than usual, despite the hot, dry conditions. Typically by this time of year my tomatoes have leaf spot diseases, caused by overhead watering splashing fungal spores from the soil to the leaves, but not this year so far (compost mulch helps with this, too).

I am going to find a solution to the lost water, and really set up a great system next spring!

  1. I'm slowly catching up on all of my blogs. I installed an irrigation setup at my house and it has been a game changer. If you want any advice I'm happy to give it! Given all the good advice I've picked up from you (especially since I'm the same area), I'd be very happy to repay it!
