Have hundreds of African daisies. All partly flowering, but about 3 ft high and all dead underneath. Look untidy. Do I cut them back hard now? How low do you cut them? Will look very bare, but should come back again, right? Never sure what to do with them. They have overtaken my very large hillside garden.

Bit of a problem here. There are several plants with the common name of African daisies. But since what you are describing in a perennial plant, and 3' tall, I'm going to guess the "bush daisy" https://www.gardeningknowhow.com/ornamental/shrubs/african-bush-daisy/growing-bush-daisies.htm
Even if you have gazanias -- https://www.gardeningknowhow.com/ornamental/flowers/gazania/gazania-treasure-flowers.htm
the trimming is the same. Go ahead and cut them back hard, they should grow back bigger and better than ever.
