Position your obelisk on an area of bare soil and push firmly into the ground. Placed on the corner of a bed, it will be prominent and dramatic, while further back, it will add solidity to the rest of the bed.
Dig a hole a short distance from the structure, larger than the plant’s pot. Add compost to the base of the hole, then position the plant, leaning inward toward the obelisk. Backfill with soil, firm and water in well.
Spread the stems out and tie to the obelisk. This will need doing regularly as the plant grows. The general rule is to tie tightly around the support and loosely around the plant, to allow stems to expand and thicken.
To soften the impact of the new structure, plant around its base. You may want to mix a few bedding plants-—for instant, summer-long color—with some perennials, which will flower and hide the obelisk base each year.
Many climbers need help to stay attached to their support. Use a soft garden twine and tie in a figure of eight to prevent the stem from rubbing against the structure.
