Reposting from another thread:
Hm, I seem to have problems watering other people's plants. First tried to water Tru's eggs which I had promised to do, but it didn't work. Then I thought maybe you can only water them (or do a rain dance) if they have less that 4 drops of water (which was not the case). But in the neglected garden I posted in the other thread I couldn't water the plants either, or rather just a single broomstick, and then the option disappeared. What's going on? Does anyone else have that problem?
Edit: Mia confirmed that we can only water plants with less than 4 drops. But what about the neglected garden? Those plants were really dry!
