Hard Freeze: Part 2

Last month I noted the result of an unexpected late season hard freeze. While many trees and flowers shook it off, others were hard hit. While maple trees seemed unaffected, the new growth emerging on oak trees was blasted. Tiger lilies were a mixed bag, probably depending on their location and how mature they were. Some were whacked while others made it through just fine.

Now that just over a month has passed since the freeze, you would hardly know it happened. Oak trees looked pretty sad for a while but then started putting out new growth, most now looking nearly recovered. Too soon to know if the acorn crop will be affected. Other trees which had been hit also have begun sending out new leaves, signaling their recovery as well. My bleeding-heart plant lost its blossoms and upper growth but has put out new leaves showing it survived. Most of the tiger lilies have recovered so now it’s an ongoing battle to keep them free of the ever-hungry scarlet lily beetles and the disgusting grubs they produce.

Many areas all over the state of New Hampshire as well as elsewhere were hit by the May 18th freeze. Apple orchards and vineyards were devastated in spite of desperate efforts by growers to save their crops. Apples, pears, cherries and much of the peach crop has been severely damaged. The fruit trees will recover but there will be little fruit for local markets this summer, only enough for farm stands.

There will be no locally produced wine as well, since the vines were blasted by the freeze and one local producer of wine reported he had to go as far afield as Pennsylvania to locate the grapes he needed to produce his wine. While orchardists and vintners are planting other crops this year, such as sweet corn and pumpkins, many have no crop insurance. One farmer stated this was the first year in 50 years of farming he had enough damage to make it worth having the insurance in the first place.

Local farmers know there are good years and bad years, so they make an effort to plant diverse crops as a hedge against problematic weather. It’s worth noting that one orchard owner after checking freeze damage, discovered that heirloom varieties such as Red Astrachan seemed to have weathered the freeze better than more recent varieties.

Supermarkets tend to stock fruits and vegetables which have a standard look and will ship well. Flavor is not always a high priority with them, only shipability and eye appeal. But these standardized varieties do not fit all climates zones, so the result is poorer performance under fluctuating climate conditions.

But this is beginning to change now. With weather getting more erratic and unreliable all the time, it might be well to take another look at older varieties of fruits and vegetables. They could very well be our bulwark against future crop failures.

Something to think about, the next time you come to plant your garden.

Happy July 4th!

Hard Freeze

By mid spring in New Hampshire most trees and shrubs have begun leafing out. Flowers and low plants are well underway with their growth. Frosts can still occur here even as late as the end of May but most plants can tolerate the frost. Things start being a little more problematic if a hard freeze occurs.

Frosts usually happen when temperatures hover or dip below the freezing mark, 32 degrees Fahrenheit or 0 degrees Celsius. But a hard freeze happens when cold air pushes in, dropping temperatures down into the mid 20s fahrenheit. Many plants can tolerate even these frigid blasts but not all can.

Just over a week ago, a freeze warning was put out by the weather service for our area and that night the thermometer dropped to the mid-twenties. Fortunately most of my plants were still in pots so they could be moved inside the garage for protection. What was in the garden already had not yet sprouted and so were protected by the soil. Still many plants were challenged by these icy conditions and not all fared well.

My bleeding heart plant, in the process of blossoming, was bitten badly. The flowers were destroyed but leaves at the base of the plant survived, so I am hopeful the plant will make a full recovery. Tiger Lilies suffered damage with smaller plants getting the worst of it. Many do not look like they will make it. Larger plants, already several feet tall, looked really beat and for a while I wondered if they would pull through. Lower leaves wilted but the tops recovered. It remains to be seen if they will produce flowers.

Many trees and shrubs shrugged off the arctic blast but a few species got hit hard. Oak trees and one or two other species I’m not familiar with got the worst of it.

At this time of year, oaks are just starting to leaf out. The freeze destroyed the new growth, leaving behind withered brown vegetation. When they are touched, they are dry, crumbling under my fingers, so these will not be coming back.

Will trees be able to survive a hit like this? Looking about, I see many larger oak trees with their leaves blasted. Many smaller trees have been devastated as well though a few twigs here and there managed to make it through. As it is so early in the season, chances are good that the trees (many of whom surely have gone through this before) will be able to put out new growth. How acorn production will be affected by this remains to be seen. I have not been able to locate any information online which might tell me this. Many animals rely on acorns, eating them to fatten up for the winter or storing them away for lean times. Bears, turkeys, squirrels, chipmunks and others will all be affected by this if the acorn crop fails.

But nature is nothing, if not resilient. Natural selection will weed out those who cannot tolerate climate extremes, leaving behind the toughest and the hardiest. Northern New Hampshire is a good place for that. Like the old saying; If you don’t like the weather, wait a minute.
