Even though they are right in front of the kitchen sink - a place I spend a far bit of time at - I still don't always get around to watering them and this is stressing the plants. I am moving more towards perlagoniums (geraniums before they were reclassified) and other sun/dry plants in those pots but its still pretty dry up there.
I spotted some water crystals at the markets meant for home decorating and wondered if they could be used to help retain the water in a hanging pot. I was feeling rich and so I spent the $5 on a small packet of plain clear crystals and took 'em home to try out...
Here's what I did...
After a week or so, I could kid myself that I haven't had to water them everyday. I remember that there were some crystals being sold at one point in garden shops a few years back to help retain moisture in the soil and wondered if these were the same thing, maybe in a different shape (for a different market). Do you know anything about those crystals and their kinship to these ones? I bought these ones on a whim without any research what so ever so I don't have a clue if they are the same thing or not.
They are meant to be non toxic - so I'm assuming that they wont leach anything too awful into the soil. I popped a few into my various pot plants while I was at it - If they turn out to be toxic to plants, I'm gonna be up for a whole bunch of new pot plants... Just as well my birthday is coming up, I could ask for plants if they all keel over!
Green-ness: 3/5 Compost or mulch would probably be just as good.
Frugal-ness: 4/5 As they went into about 15 pots.
Time cost: 6 hours to expand the crystals, 15 minutes to dig holes and cover back over.
Skill level: Just like digging in the sandpit!
Fun -ness: More fun for the plants if it works!
