The Gomphocarpus physocarpus fruit is very thin, swelling and spherical, gently squeezed by the hand, like air overflow, very like a small balloon, fruit viewing period is long, often used for potted arrangement hall and guest room, but also used as cut flower material. How to grow and care for Gomphocarpus physocarpus? The following are details.
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.
Once established, the Gomphocarpus physocarpus does not need a lot of supplementary watering. They can deal with short periods of drought.
Gomphocarpus Physocarpus is not a heavy breeder, but the top dressing of autumn compost will help them replenish the energy expended. In the spring, it's also good to add some granular organic fertilizer throughout the bed.
For slim plants, when they are about 6 inches tall, they can be retracted. Deadheading will keep the plants looking good and blooming again and again. Do not remove the entire stem, just the faded flowers. The remaining buds will remain open.
The higher varieties of the Gomphocarpus physocarpus may become a little softer, but instead of putting them on one side, they are placed in large drifts where they support each other.
If you want to cut flowers for display, be sure to imprint the cut ends of the stems to preserve them, otherwise they won't last very long.
