Hi - I have an 8'W x 7'H, large opening, lattice fence that I want to cover with this plant. I'd like to use a trough. The trough is 6' L, 2"W. They come in depths of 1'H and 2'H.. Will 1' be deep enough for this plant to grow to 7' high and maintain good health ? Can I put 4 plants in it or limit it to 3? I've read elsewhere that the plant should be granduated into larger pots as it grows. Would I not have good results if I immediately transplanted the plants into the trough rather than graduating them ? I've read elsewhere that using rotting wood to fill some of the container would provide a steady supply of nitrogen and cut down on soil costs for such large containers. I've also read about people using soda bottles and cans as filler which seems like a good recycling idea but wonder about plastic decomposing and it's impact on plant growth. I'm really in the dark as to how much room this plant will need for it's root ball. I've heard that they can get quite large. I want to provide the optimal environment for these plants so that they will cover this lattice nicely but I also don't want to spend excessive amounts of cash if it's not necessary. Any input on soil components would also be helpful. I'm really very inexperienced with gardening.
Thanks very much for your input. - Brian
