Rootstocks for Fresh Fruit Growers • We suggest that fresh apple growers plant the tall spindle system at the optimum density 1,000-1,300 trees/acre (3-4’ in row X 10-12’ between row) • G.11 • best in virgin ground • best with vigorous varieties (McIntosh, Jonagold, Fuji, Mutsu) • G.41 • best in replant ground • best with weak and medium vigor varieties (Gala, Empire) • G.935 • best with weak varieties (Honeycrisp, SweetTango, NY1, Delicious)
Rootstocks for Processing Growers • We suggest that processing apple growers plant the vertical axis system at the optimum density 600-700 trees/acre (5-6’ in row X 13-14’ between row) • G.969 • high yield but very manageable vigor • tree is free standing but the large early crops need support • G.890 • more vigor than 969 but still very productive • great for replant ground • G.935, or G.202 • less vigor than 969 so require higher density • use densities of 700-800 trees/acre Net Present Value ($/acre) 8000 6000 4000 2000 0 -2000 -4000 Trellised Systems Free Standing Systems 0 200 400 600 800 1000 1200 1400 Tree Density (trees/acre)
