I use water crystals in all my containers, a real plant saver for me. Years ago when I was still working I would see a plant on my way out the door and think when I get home I have to water that. By the time I got home they were languishing. Then I started mixing water crystals into my potting soil and never had that problem again.
These are my new head planters, I was looking for something kind of hair like but I just fell in love with these Sparks Will Fly Begonias,
