Here’s an idea… instead of buying water crystals at Home Depot, how about trying a diaper.
You read that right. Put a diaper in the bottom of your pots! The diaper will help retain the moisture in your pot. Have you ever tried it?
Does it work? From Facebook – “I have done this for about 3 years and it works really great. Just have to get a good quality diaper like luvs or pampers. I only have to water maybe three times a week unless it is hot for several days. I never had any get moldy and the roots hold them together.”
