I overstated that. They like to be kept moist outside, but, the soil is dry on top. Probably 3-4 times a week i water. Adding some epsom salts is good as fretilizer. Coffee grounds I compost and makes a nice soul for them in the garden. I dig it in for the summer, then pull it up for the winter. Makes a beautiful show in the beds. Too yellow = too much water or not enough.
Le sigh.
