When to add fertilizer to soil
New here and new gardener as well. I just had a quick question. I am currently planting pepper (Jalapeno, Sweet Banana and Bell). I've been doing extensive Googling on how to care for the plants and so far all is going well, however I am constantly stumbling on articles stating to fertilize the plants. I am using Kellogg's Patio Plus which is a ready to use outdoor potting soil with added fertilizer...but how long do I wait to actually start manually adding fertilizer to my plants. The jalapeno just started blooming three days ago but the other two nothing. I know you have to be patient - which I am, but I want to make sure I'm not missing a step.
Thanks in Advanced!
