The Q&A Archives: Mandevilla Vine

Question: My Mandevilla vine looked great for a month;
we have had 103 degree weather, so have keep
it to the interior of a tented patio to keep
it mainly in lighter shade. After a 103 degree
day, the leaves were cracked along one side and
with subsequent wind the leaves have become
withered and droopy. I have brought it indoors,
although would like to keep it on the patio.
I water it every day to keep it from drying out.

Answer: What you describe sounds like normal summer weather damage and your mandevilla will overcome the damage and begin to grow again once the temperatures cool down a bit. Take your plant back outside and set it on the patio. You can prune away the damaged shoots and new growth will emerge when conditions are cooler. Don't water everyday unless the soil actually dries out on a daily basis. Regardless of the temperatures, plants can use just so much water and if you keep the soil saturated, you'll drive out the oxygen, which is also something the plant roots need. Stick your finger into the soil to check the moisture level. If it's dry one inch below the surface, it's time to water. If it's still moist, you can wait another day or two before watering.

Best wishes with your mandevilla!
