My (2) Carolina Jessamine, Which Are Potted In Clay Pots Under An Arbor Are Suddenly Gone From Great To Drying.

Question

We are in zone 9 in Houston Texas, and for a long while they looked great and growing. now both have branches with “fried” leaves and don’t know if its too much water or not enough. I had managed to keep a perfect balance but somehow I slipped. I do not know if I should water or not? we have had 90 degree weather almost everyday and down to the 70’s eves. A third plant, a Star Jasmin is also looking sad?? I tested for moisture in the pot, and it feels damp about 3 inches below the surface, and do not want to dig deeper and injure the roots. Last year I lost 2 Jessamine plants still in a plastic pot to too much water, what can I do, If they die that’s it for me, no more trying.

Answer 1

unfortunately, your photos did not come through. I am unable to see the damage to know, exactly, what happened.

Infections from overwatering are common, as they can tolerate some drought. They cannot tolerate wet soils for long, though.

I would treat with a fungicide, and make sure that the soil has a chance to dry out, thoroughly, down to about 3 inches or so between waterings.
