But it’s a dry heat

Tucson is dry – that we know. You can create a little more humidity for your potted gardens by grouping them together, especially where they are in the shade or at least afternoon shade. Damp soil and healthy foliage can provide a more comfortable environment for both you and your plants. My shady side of the house, which is filled with pots runs about 10 degrees cooler than the sunny side. That is a huge difference. So when planning pots, include clusters for aesthetic reasons as well as creating that little bit of humidity.
