Staking Tall Plants

Tall plants may require staking. Stake each flower stem individually rather than trying to tie them all together. If this is not possible, use several stakes on the windward side and tie the entire plant securely but loosely. The intent is to catch the plant not strangle it. Do stake plants as unobtrusively as possible. Most plant stakes mimic plant stems they are thin and green. For ties use plastic strips, plastic covered wires or soft cord. For certain plants such as peony and tall garden phlox, a grow hoop works well. Similar to tomato cages, they have a large uniform opening. These need to be placed early so the plant grows up through it, naturally hiding it with its foliage.
