Pruning Report
We are still pruning and sweating out whether we will get it done in time... Blueberries 80% done, Blackberries 98%, Grapes 5%, Muscadines 0%. Any volunteers?

Chill hour report
Just like you need to sleep at night so your body can sweep/clean up all those chemicals in the brain generated by thinking during the day... Chill Hours are when plants organize all that energy stored from the previous season, prepare growth regulators, other instructive chemicals and gather nutrients for that burst of growth when temperatures warm up.

Chill hours are recorded from November 1 until end of February of each year. We use a web site called and our own Weather Underground station [free app] ( our station number is KSCsixmil4) for our results. This year we recorded a total of 1126 chill hours, which includes hours below 32 degrees. The really good chill hours, called chill units, are when the temp is between 32 and 45. This is when the plants are able to clean out the old, organize their energy and prepare for a burst of new growth. We recorded 791 chill units this year. This is the most chill hours and chill units we have measured in several years.

Once the bushes satisfy their required chill units, they will start to respond to warming temperatures. Generally warm-up is measured in Growing Degree Days (GDD - base 50 F) and for us, we start measuring the first of February each year. You can get a free App entitled "Growing Degree Days" in the App store (it has a corn stalk on its icon) if you want to try this at home.

We are at 245 GDD and we think we are ahead of schedule by maybe 10 to 12 days. Blueberry bushes are already budding. Flowers are from buds "well cracked" to "well defined flowers" all the way to Pistils extending beyond the Corolla (flower petal). In blackberries we are in bud break (buds are starting to swell) to mostly 1 inch bud burst. These stages of growth are susceptible to frost, so now we start to sweat the weather forecasts.

Our current forecast is calling for 34 degrees with 21 degrees dew point for early Sunday morning March 4, with light to no frost damage is likely. If nothing changes we will probably run the wind machine 3/4/18, the earliest we have ever run it in ten years!

Wind Machine Report

Last year we ran the wind machine with a cracked blade...really scary! So we invested $3750 in a new blade.

In addition to the blade repair, each year it is a challenge to make sure the motor (314 Chrysler industrial) is running properly because if the motor dies while the blade is running it will tear up the gear box(s). Just this year, we have already had a bad starter solenoid, bad bushing, water condensate in the gas tank and replaced spark plugs. The bottom line, we think we have it running, and we anticipate we are going to need it.

Why spend the money and what does the wind machine do? Because of the inversion effect that is created by our geographic location near the east side of Lake Keowee, there is warm air above the farm when lower temperatures set in. The wind machine creates a vortex which sucks the warm air down and spreads it over the farm. The moving air keeps the flowers from super cooling and keeps them at the ambient temperature of the moving air. The difference of 1 to 4 degrees can mean the difference of a crop or no crop.

Right now, barring a catastrophic event like a frost, (or damage from the marauders- see below) things are looking good for this year’s harvest.

Winter Marauder Report
As you will remember, last year we had serious damage from wild pigs. Last fall one of our muscadine trellises was pushed over by wild pigs. It was heavy with ripe berries at the time and the 4x4 posts just snapped at the ground line. Other damage done includes rooting for worms at irrigation emitters which busts up the trickle irrigation lines, not to mention the mess they leave behind. And unfortunately, they are still here! A family of 13 was seen just the other evening. There are rub signs on all our trees and poop showing up. We have a permit to hunt them at night, but have not had much success. Just to keep the population from growing it is necessary to eliminate 70% of them, and so far only 1 wild pig has been gotten. We also have a depredation permit for deer. Last year the deer ate thousands of dollars worth of blackberry flowers and ate immense amounts of blackberry foliage, mainly on the thornless varieties.

Threat very high for mummy berry and Exobasidium leaf and fruit spot Over the last several weeks, we have had several 24, 48 and 72 hour periods of continuous wetness with temperatures in the sixties and even low seventies. This kind of weather creates ideal conditions for these two diseases to infect blueberries. We use lime sulfur to control both. Stinky stuff but it is considered organic. It does a great job on the Exobasidium which resides on the stems of the plant to spread to developing berries and leaves and is a onetime spray. It also kills mummy berry spores on the buds and also burns back the source of the spores on the ground if we get the timing right. We tried. If we prevent primary infections then we do not need to spray for secondary infections. The problem is it is readily washed off by rain.

That is it for now!
The old timers say that if you can get past Easter without frost damage you are probably good. Let's hope we make it. Easter is early this year.

Thank so much for your support!
