I don't know how to describe it, but we had a two-tier outdoor vase that had the same type of drain holes as our new hanging plant. Before I poke holes in the hanging basket, I want to know if this is by design for some sort of botanical reason, or just a crappy kind of vase? See also my other post when I moved the other plant out of the vase: https://garden.org/thread/view...

Hi Greg -- I'm not quite sure what you mean by "two-tier outdoor vase," but the planter in the photo appears to have a water reservoir space at the bottom. Is there a perforated insert above that (where the bottom of the potting mix would be) ?

I think that elevation is for when you have plants that need/want the extra moisture. You can add holes in the bottom for those that don't. At least...that's my theory.

This planter, has an upper and lower portion (or had, it got sad looking and wife didn't want it, so it went to the curb). The plant in the middle of the upper part is the one in the other picture.

In the very middle of the hanging basket is where water drains out, but only when it gets full enough. The view is from underneath. I'm guessing that it's meant to be a water reservoir so you don't have to water it as often?

Yes, they are reservoirs to hold water so essentially part of the time it's self watering. They can go longer between watering. I don't care for them and have altered them. I throw away the top part and drill holes in the bottom. Very few plants want to be moist all the time.

I imagine that's so employees who care for them until they're sold don't have to spend as much time and water (both translate into money) on them. I don't begrudge that. In that case, I'll poke a couple of holes in it.

Thanks for the photo of the planter -- not sure why I couldn't visualize that in the first place!

The flower boxes that I hang on my deck railing have a water reservoir in the bottom that have been a godsend for me in that I could never get anything to grow very well on our south-facing deck, it would always dry out and burn up. The water wicks up through the soil and plants flourish for me with these flower boxes. (and they do have overflow drains so you can't really "overwater" them. Definitely need a well-draining potting mix, though.

I agree. They are like mini earthboxes which have saved me. I fill them up and we can get away without refilling them for almost 2 weeks while we're gone.

Given the temporary nature of the hanging basket, probably best just to leave it then. That other plant in the two-tier planter was something that was hanging around before I started getting more into gardening, hence it was neglected.
