This
is the time of year that causes dried out plants. At the nursery we see
it all the time. One of the reasons we sell so many moisture meters is
a lot of people don't recognize dried out plants.
When you dry out something the first thing to do is get moisture
back in the entire soil area. Usually it takes a slow soaking. This is
where a moisture meter can come in handy. Dry soil, especially dry soil
with a lot of organic material, repels water. This can mean lots of dry
pockets even if you do a slow soak. A moisture meter can help you
detect dry pockets.
Several years ago we had a super dry ficus in a large pot. After
soaking three times it still seemed too light in weight so we checked
with a moisture meter. About half of the root ball was still dry. It
took a couple of days to get the entire soil mass moist.
After you get the soil moist the next problem is over watering.
Yes, over watering!
If you ever get lost in Death Valley I hope the rescuers don't take
you to the closest hotel, tie an anchor to your waist, and put you in
the pool.
This is what a lot of people do. "If I just give it some more water the burned leaves will turn green."
This is again where a moisture meter comes in handy. It gives you
some real feed back on the moisture levels. You can tell if it is dry
on the surface and still wet in the center.
Generally, the ideal is to keep the entire soil mass moist (not
wet). Too much water drives out the oxygen out of the soil and causes
anaerobic bacteria to grow that attacks the roots. In addition roots
NEED oxygen to grow.
You have to be careful until the plant has enough time to heal the
root damage. In some cases it can take several months to a couple of
years.
In most cases careful care can allow the plants to recover.
Obviously not letting plants dry out is better and again a moisture
meter can help you tell what is happening before the damage happens.
