What type of fertilizer for seedlings?

Hi there,

I am growing several types of seedlings under lights (onions, pansies, lavender, coleus, impatiens, tomatoes, broccoli, kale, zinnia, bachelor buttons, etc.). I bought some MiracleGro Tomato fertilizer with 18:18:21 ratio last year and was wondering if I can use this for when the first true leaves start appearing on these seedlings. Can I use this and just dilute it to 1/2 or 1/4, or would a different ratio be better? How often should I use fertilizer?

RE: What type of fertilizer for seedlings?

These don't need any fertilizing until you pot them up to a larger size container. The MG mix is pretty intense for any seedling - I'd prefer to go with a more organic approach, like fish emulsion. If you DO use the MG, dilute to no more then 1/4 strength.

RE: What type of fertilizer for seedlings?

You should start fertilizing with quarter strength miracle gro when seedlings develop two sets of leaves. Bottom water.

I bought some fish emulsion and watered the seedlings with their first true leaves with it. We'll see how it goes!
