All of the prep work on the Turning Point apple tree like heavy branch trimming, weed killing, mulching and fertilizing should have been enough to get the scions sizes (one year old growth) we wanted. However we then hit a record breaking stretch of eight days over ninety degrees in a row( two to three days are normal in an entire summer). The heat wave was accompanied by little to no rain. Instead of our average monthly rains of 3 1/2 inches to 4 1/4 inches only one to two tenths of an inch fell every couple of weeks with only one exception of one single inch of rain from a single storm for the entire summer. By mid July scion growth had slowed considerably so it was decided to supplement the natural precipitation by trucking in water at the rate of two inches per month spread within the drip line of Turning Point.
Water is purchased at a town water station for $2 per 200 gallons and luckily it is located only three miles away from us.
Since Turning Point had a drip line diameter of 24 feet it would take close to three hundred gallons to drop an inch of water onto Turning Point. The tank holds close to two hundred and with the water set to drain at half speed thru a 1/2 inch hose it took around eight hours to dump the tank. Then one more trip to the water station for a refill to continue watering. Very quickly the leaves started looking better and scion growth continued as did the every other week of watering. Every week might have been better but the results aren’t so bad.
Pictured below is the top section of Turning Point where the one year growth of 12 to 24 inches and even higher can be observed.
Sucker branches about fifty of them on the extra heavily Trimmed Right stem ranged in size up to 52 inches long with diameters as high as just a hair shy of 3/8 inch.
Here is view of the full Turning Point Apple tree one year old growth;
Turning Point ended up with a lot more and larger one year old growth than the couple of inches it had in 2019. It did fall short of what I was hoping for with the non sucker one year old growth not looking like they hit 1/4 inch diameter. This is just a guess as I did not climb to the top of the tree to actually measure them whereas the suckers were measured as they were within reach from the ground. So was it the fertilizing, trimming or watering that made the difference as far as the larger suckers grew? It definitely took all three for the huge sucker growth. The scion growth (one year old growth)could have been due to just mainly the fertilizing. Shown in the next picture which shows typical one year old growth on trees that received an accumulated total of two to three pounds of urea total put down in two applications. It shows one year growth of 12 inches and higher without trimming or watering. There remain a few weeks of continued first year growth. It will actually be measured at scion cutting time this winter. The tree below is not Turning Point just a nearby tree to show one year old growth on a fertilized tree.
Will fertilizing of mature Apple trees be done here next year? Definitely!
edit- For those who have not tried grafting yet it is the one year old growth that is normally used to cut scions off of. And when it grows long it stands out from the general shape of the tree giving the tree “a bad hair day” look.
