I want to grow rose parade impatiens but never start them at the right time. They always out grow my pots before I get a chance to plant them out side. When is the best time to start and plant them? |
Impatiens are tiny seeded flowers that should be started indoors about 10-12 weeks before your last frost date. That would be probably in February in your area. Lightly sprinkle the seed in the surface of moistened, soilless potting soil in plastic flats. Tap the seeds lightly with your finger and cover the whole flat with black plastic. They will germinate in 2-3 weeks. Once growing, place them under grow lights, keeping the lights only a few inches away from the tops of the plants. Transplant them intoindividual 2 inch pots when they have four true leaves and keep them moist, but not overwatered. Fertilize lightly once a week and keep the room cool (60F) if they seem to be growing too fast. |
