New Guneia Impatients?

Question

Is there a trick or fertilizer to getting my New Guneia Impatients to bloom more fully? I have used Miracle Gro, fish emulsion and I get rich foilage, but few blooms. Thanks.

Answer 1

You may be giving them too much nitrogen. Nitrogen gives plants lush foliage but doesn't do much for blooms. Pick something with a higher phosphorus number. In the NPK numbers phosphorus is the second number. Cold soil 'locks' phosphorus into the soil so plants can't take it up, but that shouldn't be a big problem this time of year unless you live in a cold climate. Some sources of organic phosphorus are manure, compost, bone meal (0-12-0) and rock phosphate (0-20-0). One other thought is sun exposure. They are shade lovers. But with lush foliage I would think it more likely to be a nutrient problem.

In addition, I found the following
"New Guineas are often promoted for growing in full sun. Unfortunately, they need so much water to do well in full sun that few gardeners can keep up. New Guineas grow best where they will receive morning sun and afternoon shade. An eastern exposure is ideal. Gardeners who can water the plants very frequently may want to try them in full sun."

please refer to it as it tells a lot about Impatients.

Answer 2

I use a fertilizer called Bloom Booster. It feeds the blooms instead of the foliage. Works for me.

Answer 3

New Guineas love lots of sun and lots of water . I also fertilize mine only 2 times a yr once in spring and once in winter and then I leave it alone except for watering . good luck and happy gardening .

Answer 4

New Guinnea's want full sun. As suggested BloomBooster is specifically for enouraging flowers. Easily roots in water if you want more plants. Have fun.

Answer 5

Are they in a shady or partially shady area? If not, move them.
