Is it your house T? If you're renting I would suggest buying a big pot and planting it in there so you can take it and your tree/plant with you.

I would go for something like a Tallow or a beautiful weeping standard rose if you're putting it in the ground, or a weeping Japanese Maple (I have one potted and its beautiful) or maybe cumquat tree if you're potting.

I wouldn't go too deep because then whatever you plant won't get the benefit of its nutrients.

Did you end up encapsulting some?
