This is my first year growing, and I didn't know about adding composted manure to the soil mix before planting. I added some composted manure to my more recently repotted plants and it seems to work really well for them, they look a lot greener and healthier than my older plants. So I was wondering, is there still a way to work some in at this point? They're already in the final 5 gallon buckets and the roots are spread throughout the soil, so I can't really repot them or work the compost in directly. Would it be worthwhile to either spread some around the top of the soil, and then water? Or even mix some in the water for the next watering? I'm not sure if this would work and the composted manure would get distributed very well in the soil this way....
