Fall color in the pecan grove

 

Kanza tree, 24 Oct. 2024

        Most years we experience a hard freeze in late October that causes the complete defoliation of green leaves from our trees. This year, the combination of warm fall days and drought conditions has caused pecan leaves to remain on the trees and turn golden yellow (photo above).

     A hard freeze will also kill pecan shucks, turning them black, and promoting shucks to fully open. This year is different. The shucks are slowing drying exposing the ripe pecans inside. In the photo at right, you can see that the tips of the shucks are fully dry and have turned brown while areas of the shuck closer to the base of the nut are still green. These Kanza nuts should shake out of the tree easily and separate from the shucks allowing me to start harvesting tomorrow.

 

 

 

 

Labette, 14 Oct. 2024

     During early October, I continued to monitor the shuck split dates of all the seedling trees in my breeding block. Labette, one of the cultivars I developed, ripened on 14 Oct. 2024 (photo above). While I was observing shuck-split this year, I observed that the deeper we descended into drought this fall to more shuck-split was delayed on later ripening clones. Labette provides a good example. Labette matured on October 9 in 2023 but 5 days later in 2024.

Pecan cultivars ripening in late September

     I continue to monitor shuck-split for the pecan cultivars I have growing on my farm. Even though it seems like we are sliding back into drought conditions this fall, nut size and kernel quality appears far better than what we harvested in 2022 and 2023. 

     Cultivars ripening during late September are pictured below.

Pecan shuck-split underway


Earlton, 13 Sept. 2024



     Each Fall, I scout my pecan orchard to record the date of 50% shuck-split for each cultivar and breeding selection. As usual, Earlton was the first cultivar to split shuck (photo at right). The first indication of shuck-split is not terribly dramatic. A hairline crack appears in the shuck along the sutures. The shuck will need time to dry a bit before the shuck actually opens up (see below).

     One week after I first noticed shuck-split on Earlton, the shucks had dried enough to fully reveal the nut inside the shuck (photo at left). I even noticed one Earlton pecan ready to fall to the ground.

 

 

 

 

 

 

 

 

    The photos below represent all the pecans that have ripened during the past week. They are published in order of ripening. As a general observation, pecan ripening seems earlier than normal this year.  

   Earlton, Caney, Liberty and Thayer are cultivars originating from my breeding project. Selections numbered starting with "KT" are unnamed clones from that same breeding program.

Spring bud development 2024

Kanza, 8 Apr. 2024

     On April 8th, while the nation was enamored with watching a solar eclipse, I was in my pecan grove watching new growth emerge from branch terminals in my pecan grove.  It's the start of a new pecan season and a time of great optimism for the coming nut crop.

 

 

 

Hark, 8 Apr. 2024

   While inspecting the emerging buds of multiple pecan cultivars two key observations came to the forefront. The first was the fact that the cultivar, Hark, breaks bud later than any cultivar in my orchard (photo at left). While most cultivars were showing some some green tissue development, Hark buds were just starting to swell or were still dormant.

    The second observation I could make was the obvious difference in catkin emergence between protandrous (type 1) and protogynous (type 2) cultivars. In the photos above, the red arrows point to the male flowers on both flowering types. With the protandrous cultivar (Caney),  the catkins have already emerged from their bud scales. In contrast, bud scales still tightly cover the catkins of the protogynous cultivar (Kanza). Later this Spring, female flowers will appear at the terminals of new shoots. Female flower clusters will first become visible on protogynous cultivars while protandrous cultivars develop their pistillate flowers during the later half of the pollination season. 

   I recorded bud break for numerous cultivars on April 8th including all of the cultivars from my pecan breeding project. This year, bud break seems fairly uniform across cultivars with the exception of the late leafing Hark. In the photos below, you'll see slight differences in bud development. The bottom line is that if a late spring freeze came now, a majority of cultivars would suffer significant cold damage. The good news is that with each passing day the chances for sub freezing temperatures becomes more remote.
