|I have a small hobby greenhouse. I have not had success in starting impatiens from seed. They do not germinate. Any suggestions?
|. Impatiens can be a little tricky to start from seeds. Here are some tips for success. The seeds need light, high humidity and warm temperatures to germinate. But, the seedlings are highly susceptible to damping-off disease, so remove the greenhouse covers as soon as the seeds begin to sprout. Sow impatiens seeds on the surface of moistened seed starting mix and barely press in with your hand. Cover trays with plastic wrap or clear greenhouse domes to help retain moisture, and place in a warm area such as on top of the refrigerator (or on greenhouse propagating mats). Remove the plastic as soon as the seeds sprout and place the seedlings under a source of artificial light. Water the seedlings from the bottom and provide good air circulation around the plants to help avoid damping-off disease. Impatiens seeds will take 7-30 days to germinate at temperatures of 70F -75F degrees. Hope this information helps you grow healthy, sturdy Impatiens!
