Should I fertilize my seedlings at any point? I’ve got vegetable, flower, and herb seedlings and some are starting to put on true leaves. If I should fertilize them, what should I use? I’ve got some fish emulsion, can I dilute that and use it?
From what I have learned, it varies for what type of seedling. I usually use half strength miracle grow once the plant gets more established, usually when it’s time to repot or transfer to the ground. I was told you can fertilize once you get at least the first 2 true leaves, but I still prefer to stick to what I had just told you above. Also if you plant your seeds with compost, I wouldn’t worry about fertilizing till the seedling is larger. Just don’t fertilize too early, or you risk burning your seedlings. Hope this helps!
