Breeding points of New Guinea Impatiens

The breeding difficulty of New Guinea impatiens is not high, and three methods can be used: sowing, tissue culture and cutting. Because of the high cost of tissue culture, it is common to propagate New Guinea impatiens by cutting. The editor will give you a brief introduction to the cutting, sowing and propagation of New Guinea impatiens. Interested friends can learn about it together.

New Guinea Impatiens

1. Cutting

It is easy to take root, grow seedlings quickly and have the same color, which is the main way of propagation at present. The specific method of cutting is to cut branches about 6 cm long from the mother plant, leave 4 leaves, remove the rest of the leaves and insert them in sand or frogstone, cover them with transparent plastic bags and breathe twice a day for 10 minutes each time. Under 25 ℃, it can take root in 10 days. You can also use blister branches to make the base take root, put it in a shady place after rooting, and gradually see light after resuming growth. The cuttings can blossom soon after they survive.

2. Sowing and reproduction

Peat soil and sandy soil can be mixed at 3:1 and sterilized to prevent later seedling disease. Seeds on demand are covered with a thin layer of sowing matrix or frog stone and can germinate at 25 ℃ for 10 days. The seedling has developed root system, compact plant type and more luxuriant flowers, but it takes a long time from sowing to flowering, usually 4 months.

Distribution of origin: Tanzania, Mozambique.

Maintenance points: perennial evergreen herbs, succulent stems. As long as the temperature is suitable, it can blossom all the year round, with large flowers and rich colors, so it is suitable for potted flowers or flower beds.

New Guinea Impatiens I.schlechteri has large flowers, bright and rich colors (hybrids).

Reproduction: sowing, cutting.

Lighting: like strong light, not resistant to shade (sufficient light).

Moisture: growing in moist soil.
