South Carolina Crops: Clemson Extension Agents Provide Updates Across State

Clemson Extension agents provide updates in the The South Carolina Grower this week about the status of various crops being produced throughout the state.

Weekly Field Update

Coastal

Rob Last reports, “Strawberry crops continue to develop well with sustained flowering and fruit set. Early crops are ripening well with crops coming to market. Just a note of caution, the weather last week can be conducive to gray mold development, so fungicide programs are going to be key. Thrips are active in some crops too, so keep scouting. Melon transplants are going in the ground over the last week with development looking very promising. Peaches in the area are all but finished flowering with great fruit set. Finally, as we are looking at a cooler week for flowering fruit crops, keep an eye on the forecast temperatures to determine if protection is going to be required. Fruit and closed buds can tolerate cooler temperatures than flowers, but damaged flowers can increase gray mold development.”

Zack Snipes reports, “We have had pretty good weather as of late and it has really made things jump here. Spring greens, onions, radishes, carrots and strawberries are really pushing out hard. I counted 57 green berries+flowers on one strawberry plant. If someone can beat that number, I will give you a Free Crop Handbook. The blueberry crop is looking great with a good fruit set on highbush varieties and tons of flowers right now on the rabbiteye types. We planted around 30 citrus trees on Friday as part of a Specialty Crop Block Grant. We have around 75 more to plant next year. All in all we will plant somewhere around 40 varieties with varying scion and rootstock combinations. We are looking at cold tolerance in both the lab and a field setting and monitoring for citrus greening. We will plant everything from kumquat to grapefruit to finger limes.

Justin Ballew reports, “Last week was pretty cloudy, but we had a couple of beautiful days that reached the 80s. Though we’ve had a little bit of rain, the air has been thick with pine pollen. We’re seeing a few strawberries ripen, but we’re still not at the point where we can open the U-Picks. We’re running a little behind where we’ve been in the past few years, and I suspect all the cloudy weather we’ve had over the last month is partially to blame. I’m seeing a good bit of misshapen fruit, which is normal for the very first fruit that develop. This is usually related to pollination, but make sure you tissue sample to make sure boron levels are where they need to be. Watch out for the cool nights in the forecast later this week. We may need to cover. Spring planted brassica crops are looking good. Diamondback moths are showing up in places, especially near fields where a fall crop was grown through the winter, so be sure to destroy those fields once harvest is finished.”

Sarah Scott reports, “Peaches are progressing quickly with small fruit forming on early varieties. Georgia has reported plum curculio activity in the middle part of the state, so orchards in the Ridge of SC can expect to see activity in about 2 weeks. Check the 2021 management guide for control options which include Imidan, Actara, Belay, and Avaunt. Strawberries farms are on track to begin picking regularly April 1. Spring greens are being transplanted as well.”

Tony Melton reports, “Strawberries are ready to burst forth, and there are already some fruit on Ruby June. Working to protect strawberries and peaches later on this week. A lot of summer crops will be going into the ground after Easter. Pickle growers are biting at the bit.  Most greens are just emerging. Cabbage is enjoying the weather and getting to what I call the whirl stage so hope we have no damaging winds to wring them off. Sweet potatoes slips are just emerging on the beds.”
