I've been thinking on this one some, because it is such a good idea... my ground space is limited and frankly I have a hard time knowing what space has what kind of sun exposure so I'd like to be able to move it if I find I've guessed wrong the first time or two.
A pole or multiple poles (such as tripod or multiple vertical poles) is a good option but a 1 foot diameter pot is hard to get more than one pole into (or maybe I'm just not talented at it).
I wondered about a tube/cone/other shape of chicken wire or other sturdy metal garden fencing wire (the plastic I've tried is floppy and would need posts to hold it up, kinda defeating the purpose of using the fencing material) - it would be lightweight, and could be "pinned" to the soil instead of trying to bury something in the pot and expecting it to remain stable (my efforts at this usually fail).
I'm pretty sure the morning glory would like this (3-4
seeds equally spaced in the pot so it will grow fuller perhaps? - I'm guessing here), and cypress should like it just fine too (make it as tall as you can and
plant seeds maybe 6 inches apart).
Maybe the hyacinth would like it too if you make it tall enough and keep winding it around as it makes new growth but I haven't grown hyacinth yet.. what do you think, Joclyn?
I'm glad you started this thread, Kenny, and glad for the ideas coming forth in response (I love the bird cage idea, angelblossom, and njoynit the hanging pots and
tree idea are great too!). This has solved a problem for me - limited horizontal
growing space but plenty of vertical!
