Wilting Cucumber Leaves in Upside Down Pot
I am growing cucumbers in a Topsy Turvy. I planted two seedlings in one planter. All was well. Both are bearing fruit. Both are healthy. We had a slow start to the summer with a lot of rain and cool weather. Now it is dry and hot. I have been keeping it well watered in the morning. Each morning it looks beautiful, but by 11 am and in 80 degree weather, all of the leaves are wilted. It is in full sun, as I know cukes like full sun. I am wondering if the soil inside the Topsy Turvy just gets too hot and the roots don't like it so hot. It seems to recover at day's end and is fine over night. Should I try to cover the 'pot' with reflective paper or something to shade it from the hot sun? Help please!

They are wilting due to heat stress. In containers they need more water than those planted in the ground, especially when temps rise above 85 F. You should be watering them at least twice a day, as the container tends to dry our much faster, leading to the heat stress you are seeing. You can shade the area, if desired, or simply move the plants to another location during the hottest part of the day.
