fretilizer formula

Post by pegramj » Fri May 29, 2015 12:32 pm

On a visit to Andre Viette's garden a number of years ago he gave out a fertilizer formula a gardener could mix themselves. It calls for equal amounts of plantone, green sand and rock phosphate. Then my notes say "Add ironite and osmacote" but don't say how much of each should be added. Can anyone help?

Is this a general fertilizer and should it be added to the soil each time a new planting is made?

We recommend the fertilizer mixture you mentioned especially for new plantings and new beds ( Rock phosphate and Greensand only need to be applied every 3-4 years. Plant-tone and Holly-tone should be applied each year in the spring and again in the fall.
Ironite can be added as directed on the label if the plants do not seem a healthy green. You may not need to add this if your plants are green and healthy looking.
Osmocote is a long-feeding, slow release chemical fertilizer that can be applied (if desired) according to the label directions. This is not really necessary if you are feeding with Plant-tone or Holly-tone. However, it will provide nutrients to the plants a bit quicker than an organic fertilizer because it doesn't need to be broken down first by soil organisms. Use it according to the label directions for a quick but long lasting boost to your plantings.
