Two years ago I was given an echeveria plant. Up until that time I had no idea how to keep a succulent, well truthfully most indoor plants, alive. Fortunately it came with watering instructions, an eye dropper pipette thing that looks like this, and a little bamboo pokey stick. (Disclosure: I am including affiliate links in this post for your convenience.) The instructions said to poke the stick in the soil. If the stick is damp/wet the succulent doesn’t need watering. If the stick comes out dry, water the echeveria with one graduated pipette full of water. I followed the same instructions (with slightly more water because it is a bigger plant) with the aloe vera plant buddy I bought the echeveria so he wouldn’t get lonely.
And whaddaya know? Both plants not only lived but they grew so much I had to repot them after I found an even easier and lazier way to water but not over water my succulent plants.
