Some people think our summer rains have begun, but more people are still waiting as they watch the clouds pile high and turn to dark moisture-laden promise. There’s even some lightning and thunder and everything looks promising. However, it seems that other people all around you are getting the welcome rains and you are being denied. You hope and hope it will soon be your turn.
Summer rains are of short duration and they are insufficient for our plants. They lay the dust and spot our windows. Therefore, you should still keep irrigating and keep irrigating until you can poke your soil probe down to root level.. As a reminder the distances you need to keep in mind are as follows. For vegetables and flowers it’s twelve inches. For roses and other shrubs it’s two feet and for trees it’s three feet. Make sure that you give good soaking times to get moisture down deep enough–casual sprinkling is not good enough.
You can avoid the cost of having a metalworker make you a soil probe out of a three- foot length of re-bar by visiting a thrift store and buying a golf club (a driver meets the length need) and then sawing off the head.
Now you are ready to test the effect of the rains each time you get favored by the rain god. But in the meantime please keep irrigating. While you are waiting for your share of rain remember that, although the showers are so localized, the humidity is universal. Humidity is not that helpful because the stomates on the leaf surfaces are encouraged to open up. (in extreme drought conditions the stomates stay tightly closed and that enables the plant to conserve moisture).
To save your plants, keep irrigating.
