I had a cutting from one of my house plants started in a six pack. I left it in too long and noticed some really thick, long roots were climbing out of its compartment and into the adjoining compartments. They were perfectly molded to the container! So here's my winter project:
I put a cool looking rock in the 2L bottle, then put the started plant on top of the rock and just barely covered the whole works with soil. I'm going to keep the soil surface fairly dry, so the roots have to grow down along the rock to moisture. As the roots get deeper I'll cut the bottle down and brush the soil away, making the roots go deeper and deeper. Eventually the whole rock will be exposed, with roots wrapped around it. Then I'll set the rock and plant on top of some soil in a real planter.
The idea is to make it look like those trees I see pictures of in the jungle. They appear to be growing right over the rubble of old ruins and stuff....
What do you think? Is this a bit too crazy? Do I have you worried yet?
