Q.getting impatiens to bloom
Grew impatiens plants from seeds. They are large healthy looking plants but no blooms. What am I doing wrong? This is the first time I have grown impatiens from seeds. Usually just buy the small plants blooming and transplant and grow them in shade around oak tree.
Lack of sunlight, over fertilizing, over pruning, water and heat stress are the most common reasons for lack of flowers.
Make sure the plants have plenty of morning light is best. A fertilizer high in nitrogen can cause lack of flowers. Withhold fertilizer for a bit or use a fertilizer designed for flowering plants.
Pinching back plants is good to form nice compact plants, but removes buds.
Make sure you are watering regularly and evenly. Container plants likely need daily water.
In high heat, plants may stop blooming.
