Problems With Existing Pepper and Tomato Plants

Question

I have green pepper and tomato plants in pots on my patio. The patio has screen on the sides and a vinal roof covering to keep out rain. The leaves on the pepper plant keep drying out and falling off. The fruit has stopped growing and no new blossoms are being produced. The stems on the tomato plants are turning yellow and the new blossoms come but also dry out. The only new growth is at the very top and it eventually dries out. I water at least two times a week on both plants and use Miracle Grow each time. The temperature has been reaching 90 degrees outside and with the vinal top on the roof, it probably gets even warmer. Is it too hot in the area for the plants to survive? I also recently planted an up-side down tomato plant and the leaves that are exposed to the sun are drying out.

Answer 1

Plants in containers outside need to be watered daily, twice daily if the temps are above 85 degrees F. Increase watering and they should improve. Plants outside use water much, much faster than the ones grown indoors.
