One of the most common questions among gardeners is: "When should I start fertilizing my seedlings?"
Fertilizer isn't necessary when starting the seeds because the tiny seed contains everything the plant needs to germinate. However, once seedlings emerge and begin to grow, they need supplemental nutrients to promote healthy growth.
Purdue University recommends applying a water-soluble houseplant fertilizer, such as 15-30-15, mixed to 1/2 strength a few days after the seedlings emerge.
Apply the mixture at the recommended strength in approximately two weeks and repeat at two week intervals.
It should be noted that young roots are easily damaged by fertilizer. Make sure the soil is moist before applying fertilizer to avoid injury to roots.
Until Next Time . . . HAPPY GARDENING!
