Mid-June 2020
Onslow County Center
The  Longest  and  Slowest
Growing Season Ever 
By Lisa Rayburn, Area Agent- Commercial Fruits and Vegetables

As I am writing this article, it is a chilly 66oF and raining on June 15. The weather feels more like March than just a week before the summer solstice. I'm feeling confused and my garden is too. Let's look at the way this year's unusual weather is impacting our gardens. 

Looking back, we had an unusually warm, mild winter. We made it through the winter with very little cold weather and only one snow event. This warm winter was followed by an unusually warm March. These high temperatures were coupled with unusually warm nights. This extended period of warm weather lured many farmers and gardeners, including myself, into planting early.  

You may remember from a previous article I wrote that the last average frost in Onslow County is around April 7. That means half the time, the last frost occurs before this date and half the time, the last frost occurs after this date. So those of us who planted out warm season crops the end of March, first week of April were definitely playing the odds that a frost might still occur and damage our crops. And several frost events did threaten us.  

Our unusually warm weather came to a sudden end with a frost advisory the night of April 9. We weren't out of the woods yet as we had another frost advisory on April 15-16 and even one more in May. These near-frost events were not at all unusual in their timing, but coming as they did after a long, warm period and early planting, there were lots of crops in the field to be at risk. Luckily, most of us scraped by without significant damage except in exposed locations or recently transplanted crops.   

The balance of April was stormy and relatively cool, the 53rd coolest on record according to the state climate office. May was also wet and relatively speaking, cooler, ranking as the 13th coolest May since 1895. May continued to be turbulent - we had a frost advisory on May 10, followed by Tropical Storm Bertha, followed by more rain than we average in a month dumped in a week. What a wild ride!

Now, only two weeks into June, we've had a couple of days in the 90s followed by a week of unusually cool, wet weather again. The high temperature today is forecast to be 68o F here in Jacksonville.  



What is the  impact of this on our gardens?  

First and foremost, warm season crops are growing more slowly than we would expect. Even if you planted earlier than normal, your crops may not be ready to harvest as soon as you expect.  Lower temperatures means slower plant growth and slower fruit development and ripening.  Fruit that do ripen under these conditions are likely to be less flavorful and sweet. The upside is that the cooler temperatures have been great for cool season crops like leafy greens, cabbage and collards.  Many of these plants are growing better than they would have if the temperatures had been higher.  

All of this rain is leaching nutrients out of the soil and away from the plant's roots.  You may need to fertilize a little more to keep plants vigorous.  If you grow in containers, raised beds or sandy soils, a slow release fertilizer is a good option as it is less likely to leach than a granular or soluble formulation.  If we get a period of dry weather, a soluble fertilizer will give your plants a quick pick-me-up but these formulations are easily leached out of containers and sandy soils during rain events.  Adequate nutrition is critical to optimize yield and reduce the likelihood that your plants will succumb to disease. 

Realize that you may lose some fruit set due to lack of pollination. Crops like squash, cucumbers and melons rely on insects to move pollen from one flower to the next. Bees don't fly under cool, rainy conditions and female flowers that are not pollinated will not grow into mature fruits. Even crops that are wind-pollinated like sweet corn will not pollinate well under cool wet conditions.  Rain knocks pollen out of the air and prevents it from moving to the target location.  Don't be surprised if you see problems down the road that relate back to poor pollination occurring now.  

This rain is doing us no favors when it comes to disease development.  Whether the raindrops are splashing fungal and bacterial leaf spot diseases from plant to plant, or soggy soils are setting plants up for root rots, the excess moisture isn't helping. Scout your garden, have diseases identified accurately, and consider using a fungicide, if appropriate, to protect your crop. Fungicides prevent diseases rather than controlling them once they have started. A fungicide applied prior to a period of rainy weather can go a long way towards protecting your crop. Most fungicides will not control bacterial diseases so accurate disease identification is critical for successful control. Make sure you read and follow all label directions. 

Expect some initial wilting when conditions change from cool and wet to hot and dry.  Plants will not be adapted to those conditions and will likely struggle for a week or two as they transition.  Extended periods of wet weather can saturate the soil, damaging plant roots.  These plants will exhibit stress when temperatures heat back up and the damaged root system is not able to keep up with the plant's moisture needs.  If temperatures go from cool and wet to hot and sunny, plants will be struggling to keep up.

However, don't overlook the risk of root rot diseases. There are many pathogens that can take advantage of plants in wet soils. Bacterial and fungal root rots flourish in wet soils.  If you have plants that are struggling, contact the extension office and accurately identify the disease so you can make adjustments for next season or the next crop.  

Cool wet conditions can also exacerbate blossom end rot on crops like tomatoes, peppers, and eggplants as well as fruit rots of cucurbits. Assuming that you have limed according to your soil sample report and your nutrition is on point, these diseases should improve with the weather conditions.  If they don't, consider a soil sample to fine tune your fertility program and use calcium nitrate as a fertilizer source to provide additional plant-available calcium.  

Finally, cool wet weather can cause pre-emergent herbicides to be less effective. If you applied trifluralin to control weeds, it may not do the job as well as it normally does.  It may be leached out of the soil.  Also, cool soil temperatures mean that some weeds, like crabgrass, will likely emerge later than expected, after the chemical is no longer effective.  This holds true if you applied pre-emergent herbicides to your lawn as well.

Farmers markets are spacing vendors further apart, encouraging produce to be pre-packaged, asking customers not to handle produce they aren't purchasing and making hand sanitizer readily available to customers and vendors. 

Remember that  all recommended practices to avoid COVID-19  still apply. 

DO NOT shop if you are sick, may be sick or 
have been exposed to someone who has COVID-19. 

Stand at least 6 feet apart.

Avoid high touch surfaces.

Wash or sanitize your hands regularly.

Avoid touching your face.
