I sure hope everyone weathered the latest bout of snow and ice safely. I’ve heard reports from folks throughout the county of 1-3 inches falling. I was asked about the snow to rain equivalency. According to NOAA typically it takes 13 inches of snow to equal 1 inch of rain. That ratio can vary depending on how wet or dry the snow is. Our snow is probably average so if you had one inch of snow the rain equivalent is approximately 0.08 inch; if you had three inches then the rain equivalent is approximately 0.23 inch of rain. The weather station at the UGA Bledsoe Farm in Griffin reported a total of 0.11 inches of rain for January 17-18. The station in Pine Mountain at Callaway Gardens reported 0.10 for the same time period. Using the ratio above then approximately 1.5 inches of snow occurred where the stations are located.

THE SCIENCE BEHIND PRUNING MUSCADINES

I mentioned pruning muscadines in the first week of March the other day to someone and was told that muscadines should be pruned earlier or they would bleed. Research has shown that bleeding does no harm to muscadine vines and does not impact production. It’s also usually hard to avoid; in a really mild winter you won’t be able to keep them from bleeding. Bleeding in grapevines is as much a result of warm soil temperature and adequate soil moisture as it is the pruning. These conditions trigger water uptake in actively growing roots. The pruning cut creates the pressure that pulls fluids through the xylem tissue much in the way that evapotranspiration in leaves does during the growing season. Or in some cases osmosis may be the cause as an equilibrium between moisture in the soil and moisture in the roots is created. If our soils remained below 45º F and we experienced dry winters bleeding would be less likely to occur. But we don’t. I’ve pruned muscadine vines during really cold weather only to have the vines bleed a week later when the temperatures warmed up. So avoiding bleeding is not the real concern. What is actually more important is pruning too soon.

Last winter was one of the mildest on record. Despite that claim, on March 16th temperatures plummeted to the low twenties causing damage to flowering peach trees and blueberry bushes throughout Georgia. Our winters overall have been getting milder over the past years but severe cold temperatures are still occurring late into March and even into April. Pruning coupled with mild temperatures can trigger plants coming out of dormancy earlier than they normally would. Pruning stimulates the production of plant hormones that stimulate new growth. If that happens and we still have severe cold snaps occurring all of that new growth will be damaged. The plant will have to dip into stored energy reserves to produce more shoots. Muscadines are normally one of the latest fruits to come out of dormancy so they can also be one of the latest to be pruned. My usual recommendation for pruning of any fruit trees or vines is to try and have it done by mid-March. Commercial producers don’t have the luxury of pruning at the “best” time. Most start when they have the time and the labor. If mechanical pruners aren’t used and the acreage is extensive pruning may take months. Waiting for a time when the vines won’t bleed isn’t going to happen and yet commercial orchards still produce fruit year after year.

The two most common problems that I’ve come across in the past twenty years that impacted production in the home garden were over pruning and growing only imperfect flowered cultivars. When pruning vines you should leave at least two fruiting spurs on one year old shoots growing off the cordon or arms. I’ve seen folks prune all of the spurs off. No spurs; no fruit. I’ve also spoken to folks who had no idea that muscadine varieties can be self-infertile. Usually you know this is a problem if someone tells you they have a plant that flowers but never produces fruit. If they received the plant from a reputable nursery than more than likely it’s a female flowering variety that needs a self-fertile or a male flowering plant for pollination to occur. If it’s one they removed from the wild then it’s a toss-up whether it’s a male or female flowering plant. Typically, male flowering plants are more common. Examination of the flowers will tell. Buying from a reputable nursery and paying attention to pollination needs is more likely to bring you fruit faster though. Muscadines are one of the most forgiving of plants. They are well adapted to the southeast and are typically very vigorous growers. If you mess up pruning one year there should be plenty of growth next year to correct mistakes.
