Determining the optimum time to remove seedlings from containers will vary season to season and at your location versus another grower.

To this add 6 pounds of 18-6-12 Osmocote (NO substitutes), plus one pound of Micromax, plus a small amount of dolomite ONLY if you have very little calcium in your water supply…
