Hi Welcome
Pic help us see how the plants are doing. Is your soil quick drying? What you add to your soil for your area is a big thing. Also what type of fertilizer and how often. When was the last time you re potted? Are you using the rule of 2.5" from the pot to the caudex all the way around. Some use a 3" to 5" deep pot. Have your ever pruned for more branches and flowers? How do you water and how often.
