Our weather will only continue to have more extreme shifts in temps, storms, drought and flooding due to climate change. We have to make changes and we aren't.

So they are assessing the damage... Wheat prices have gone up.

and look at the prices of iceberg lettuce and avocados plus asparagus this spring due to all the rain in California. It does look like those prices are coming down a bit this week.

As we know, its the cold and snow that are a threat to gardens and farms, not warmth and drought.


With that said... heads up next few days depending where you are.


Frost threat coming in DC area. Water those Strawberries.

The Chicken Or The Egg?
Glass half empty or Half Full?

Was the Crop damaged because of the Late Sub Freezing temps or the Early Warmth? If there wasn't such cold temps damage wouldn't of occurred. Then again, if there wasn't early warmth it wouldn't of occurred either. Either way, I think we can agree the cold was the one to physically damage them.

Article with link shows the damage to Apple Crops in Northeast and a bunch of cool graphics! Posting most of article in case link gets lost in future. Good info on the Apple Crops.




Quote:


"Similar conditions last winter also resulted in abnormally high freeze damage to apple and other fruit crops in the Northeast.


Spring freeze risk in apple blossoms depends on three sequential factors: 1) the accumulation of winter chill units, 2) the accumulation of growing degree days, and 3) the probability of occurrence of damaging sub-freezing temperatures. During winter, apple trees must experience a period of chilling before the overwintering blossoms can begin to develop. Ideal chilling conditions occur between 35F and 60F with warmer temperatures counteracting previously accumulated chill units and colder temperatures not contributing to chill accumulation. Most apple cultivars grown in the Northeast require between 1000 and 1200 chill hours, a threshold that is typically met in late January or early February.
Once chilling is met, apple blossoms can begin to develop. This development can be tracked using the accumulation of base 41F growing degree days*. Dormancy is broken after accumulation of approximately 100 degree days, when the blossoms enter the silver-tip stage. Blossom development culminates in bloom at about 400 degree days and finally petal fall at approximately 500 degree days. Early stages like silver-tip are able to withstand temperatures as low as 5F without significant damage, while more advanced stages, such as bloom, experience damage at temperatures in the upper 20s."


Using the Applied Climate Information System (ACIS), the Northeast Regional Climate Center (NRCC) has developed a series of tools designed to help Northeast growers track the risk of freeze damage to their crops. The tools rely on recent and historical GHCN temperature observations and forecasts from the National Weather Service’s National Digital Forecast Database. Each morning the Northeast Regional Climate Center creates a regional temperature map using GHCN observations. National Weather Service Rapid Refresh model initialization inputs are used to guide spatial interpolation of the observations (filling in areas without data) and to account for topographic temperature variations that are not well represented by the observations.

Whoa.. just came across this link... Great tool! Still exploring. Check it out. Shows the probabilities of damage. Check out the min temp forecast May 8th. Getting close to the 28 mark for 10% damage. This is for Southern NY near PA border. You can change locations.

I read on one of the posts that wheat prices jumped 2%


Let's put that in perspective for non-farmers.


That would be like gas going from $2.10 per gallon to $2.14
