keeping my house plants hydrated while i am away.



How often you're away isn't important... what's important is how long
you'll be gone. Most healthy plants when properly watered can survive
quite nicely for up to ten days with no care at all. Many plants,
like succulents and cacti don't require watering but *lightly* once
every month or even two months. With most plants less is more.. many
folks kill their plants with kindness... they over water and just as
bad they over fertilize. Of course some plants, like orchids,
violets, etc. require special care and rreally shouldn' left more than
a day or two. Without knowing what kind of plants you have, their
ages, size of plants/pots, type of pots, type of potting mix, room
temperature, etc, it's really not possible to give detailed
instructions.
