I have some important advice for anyone who is planting apple and pear trees -
Take Frost Pockets into consideration. Frost Pockets occur at low ground where cold air can fall and settle. Remember - warmer air rises and colder air falls. Many years, just a degree or two of temperature can be the difference between a bumper crop and a total failure. I'm not saying to completely avoid planting trees in low areas, but I would recommend using some restraint until you can gauge how bad the impact might be on your particular piece of ground.
Telling my own personal experience with my frost pocket at my farm is the best illustration that I can give for this subject. At one point in time, all of my trees were planted on high ground away from my low ground. However, in 2014, I decided to add a few more trees, and I planted some in the low area and some on the high ground with the other trees. Since that time the difference in fruiting has been dramatic. Shown below are some bullet points with the most important facts:
- In the low ground area, The pear trees I planted in 2014 have never been able to produce. Last year one of the trees had 4 or 5 pears on it, and that is the only pears I've ever seen down there. However, the pears on the high ground started producing 4 years after they were planted, and have been doing great ever since then. The two groups of trees are only 300 yards apart, and the only difference is the elevation.
- Even though the pear trees in the low area haven't been able to produce, they have grown big. They are much larger than the trees that have been producing. That make perfect sense, because if you aren't making fruit, you have more energy to devote to vegetative growth.
- The apples and crabapples in the low area have been able to produce some, but they have not been as productive as the trees on the high ground. It looks like that could possibly change this year. They are loaded with blooms, and unless we have an unusual late freeze, they look to be on par with the high ground trees this year.
- This year, the pear tree blooms in the low area have already been frozen out again. They are already black and falling off the trees. The high ground pears, however, look great and have a fine fruit set.
- Persimmons and Sawtooths are not affected by the frost pocket. In the last 10 years, I have only seen one bad crop with those species. That was a year when we had a very unusual late freeze in May.
I just wanted to pass this information along and hope that it might help others. PS - unless we have an unusual late freeze, it looks like 2022 could be the best apple and pear crop I have seen in my life. Take care. and good growing.
