Understanding Growth Habits
Rhizomes and seeds allow the obedient plant to spread and take over a region if left unchecked. It grows in full sun to light shade and prefers moist, well-drained soil, but it may withstand other circumstances. Controlling its spread requires understanding these growth characteristics.

Another key phase is division. Dig up and separate clumps every few years to control size and spread. This rejuvenates and controls the plant, promoting stronger blooming.
Using Root Barriers
Root barriers can help inhibit the plant’s spread. For rhizomes to not propagate underground, these barriers should be buried 12-18 inches deep. These barriers can be made from plastic or metal edging. This strategy is good for garden beds where you want to restrict plant growth.
Container gardening
Container gardening is another good technique to manage obedient plants. This prevents it from spreading across your garden. Containers on garden beds or patios allow for versatility in garden design while controlling the plant’s aggression. Use high-quality potting soil and spacious containers to accommodate the plant’s root system for optimum growth.
