This afternoon I walked out to some Kanza trees and found that many leaves looked freeze dried but were still hanging onto the tree (photo at right). Frozen pecan shucks typically appear water soaked after a hard freeze but this morning the shucks looked just like they had last week.
I'll be interested to see how my trees react over the next few days as temperatures climb back up into the 50's. I expect to see partial defoliation but I'm afraid the shucks will continue to hang tight around the nuts preventing them from falling freely.
With the soil under my trees rain soaked, it looks like it will be some time before I can start shaking trees and harvesting nuts. But, gosh darn, its hard being patient.

Today, I applied 53 lbs/ac nitrogen, 38 lbs/ac phosphorus, and 50 lbs/ac potassium. Including the cost of spreader rent, I invested about $64 per acre for this fertilizer application. That sounds like a lot of money but making regular fertilizer applications is the best way to build tree health and ensure regular nut production.
I plan to spread additional fertilizer in the early spring of 2020. In my experience, twice-a-year fertilizer application has proven to help reduce alternate bearing and increased overall yield.

The trees I purchased were grown in 3 gallon pots and had tops that were three to four feet tall (photo at right). I prefer planting trees at this time of year to take advantage of the natural flush of root growth that occurs as trees prepare for dormancy.
You should also note the large, circling roots that have developed along the bottom of the pot. Before planting, I like to prune off circling roots to prevent any possible root girdling that may occur as the tree grows larger.
I do not recommend using a post hole digger to dig holes for container-grown pecans. Post hole diggers have two major drawbacks. First they tend to dig a hole that is too deep. If a too-deep hole is back filled and a tree is planted on top of the fill, the entire planting hole will settle over the winter and the tree will end up drowning in a puddle of trapped water. The second disadvantage of using a post hole digger is that the spinning action of the auger acts to compact the inside surface of the hole making it difficult for tree roots to grow out into the surrounding soil.

The combination of a wet summer and no fungicide applications has allowed pecan diseases to run wild in many native pecan groves this summer. I spent some time today taking some photos of some common pecan diseases.
