Gardening in Summer

This being only the second year of my balcony gardening in Dubai's hot climate, I am still on a learning curve. A part of the garden is still lush green, the other part is not doing so well. I made a mistake with the tomato planting season and also I think with the salvias. The salvias all have buds but they are much smaller than one would expect. I think that too probably should have been planted in winter. Well, summer here is sure no time for growing plants.
