Growing Gomphocarpus physocarpus

Soil: gomphocarpus physocarpus prefers acidic soil with a pH range of 5.8-6.8.

Planting: You can start with a plant or seed, although seed plants will not flower in the first year. Seeds of physocarpus gomphocarpus need to be layered and are a good choice for winter sowing.

Start sowing indoors in early spring, gently pressing the seeds into the moist soil. They need light to germinate, so don't cover the seeds with soil. Seeds should germinate within 2-3 weeks. Before transplanting outdoors, transplant the seedlings into a larger pot and slowly harden.

You can try to break it up, but the roots are dense and chunky, and the taproots are long and don't like to be disturbed. Instead of digging through the whole plant, cut a piece with a sharp blade. Make sure you get at least an inch root. Put it away and keep it moist. If you're going to try to differentiate, do it early in the season, when plants are very young, and expect them to flower again in a season or two.

These plants appear very late in spring. Mark their location so you don't try to root them.
