Started my seeds approx 10 days to 2 weeks ago. Used to raise all my flowers from seed up until about 15 years ago; I raised children instead. I started with Tom Thumb impatiens and dwarf snapdragons. My snapdragons are barely poking out of the soil and my impatiens are 2 to 3 inches tall. I cannot plant in my area until after May 20th. How do I save my impatiens from being too leggy to make an attractive bed when I do plant them?
Increasing the amount of light that your seedlings receive is the key to success.
