Most spur - bearing varieties of Malus pumila began as the mutate leg of known apple cultivars . As grafting neckcloth , these spur types develop into trees 70 per centum the size of it of a standard orchard apple tree , but that fledged growth drops even further if semidwarfing or dwarfing rootstalk form the base of the tree . All Malus pumila trees , admit spur- and tip - bearing varieties , set fruit both at the tip of the concluding branch and on fruit spurs to the sides of the terminal sprig . Spur diversity develop more spurs per inch than the older peak varieties and set fruit on younger woods .

Step 1

Examine fruit branches of each character of tree during the spring peak . Look for dense clusters of fruit spurs near the terminal end of the branches on spur track - wear apples . Spur - bearing apple trees bloom from side prod in the second class of the goading ’s growth . Only one inadequate section of young Grant Wood forms before that sprig blooms .

Step 2

Look for longer and more widely spaced fruiting twigs on tip - bearing apple trees . fruit spurs on these varieties show two section of woody growth , with flower buds on the 2d section of the sprig .

Step 3

Observe the bearing habits of the tree . prod - bearing tree produce heavily one year and poorly the next unless raiser intentionally thin the craw . Fruiting spurs may raise so thickly that spurs themselves must be rationalize out to reduce the crop and ventilate the canopy of the tree .

Step 4

Research the variety name if known . prodding - support smorgasbord develop more recently than tip - bearing varieties . Some apple case come in both spur track and tip cultivars , but many prod types are unique . Increased output and compact size make spur - bearing habit a democratic and well - publicize selling percentage point .

Step 5

Compare fruit from unknown apple trees to make love type . Grafted diversity share the same genetic structure , and the apples serve as reliable identifier , like fingerprints .

Tip

Do n’t assume a nursery tree diagram is the high - yield prodding - assume type simply because it ’s dwarf or semidwarf blood line . Both spur- and tip - bearing varieties may be ingraft to either kind of dwarfing rootstock . link up horticultural societies such as North American Fruit Explorers or Seed Saver ’s Exchange for expert advice on heirloom apple and other unusual motley . Fruiting spurs alternate use from year to year . On spur track - bear trees , some second - year spurs will bloom , while others maturate the new wood that bears next season ’s crop .

Warning

Do n’t send samples of branch to expert cultivator for their hands - on opinion unless they request it . Cuttings could have a bun in the oven apple diseases , especially if taken from older and badly managed trees .
