There aren’t many more frustrating things than growing seemingly healthy tomatoes, those plants setting an abundance of flower and fruit, and then, once your tomatoes get about the size of a golf ball, having the fruit rot away from the base. This very common condition, called Blossom End Rot (BER), is caused one of two ways: by either a soil calcium deficiency or disruption of soil calcium uptake by the plant. Fortunately, preventing BER from occurring and then realizing an awesome crop of tasty tomato fruit is relatively simple and home gardeners have a couple of possible preventative solution!

caused by calcium deficiency, it can be induced by creation of distinct wet and dry periods from non-regular watering, interfering with calcium uptake and availability to the plant. So, while you may have adequate soil calcium, if you don’t water correctly, the condition will happen anyway! It’s also good to keep in mind that mature tomato plants use large quantities of water daily, so during the heat of summer, plants in containers may need to be watered multiple times daily to maintain consistently moist soil. Think about it, you don’t drink 8 glasses of water when you wake up and then never drink again throughout a hot day. A tomato is no different. Allowing your plants to wilt down before providing additional water ruins productivity and can induce BER.
Blossom End Rot, while one of the more destructive fates of tomatoes, is totally preventable by a little legwork early in the growing game from you! Soil test and change pH with lime if needed, add a shot of calcium through a tomato blend fertilizer or non-lime supplement like gypsum, and water regularly! Do these three things and you’ll be well on your way to a great crop of early summer tomatoes. If you have any questions about tomato blossom end rot or any other horticulture or agricultural topic, please don’t hesitate to reach out to us at the UF/IFAS Calhoun County Extension Office. Take advantage of this beautiful spring weather and get in the garden today! Happy gardening.
Cruciferous vegetables, mostly cool-season annuals in the Brassicaceae (formerly Cruciferae) family, are part of a healthy diet, prized for their high fiber content and unique sulfur-containing compounds known as glucosinolates. This vegetable family includes things many of us love (or love to hate) like Brussels sprouts, cabbage, cauliflower, collards, kale, mustard, turnips, bok choy, and Chinese cabbage. They’re also commonly grown in Panhandle gardens. However, as anyone who has grown these species knows, some are easier than others. For example, kale and radish are among the easiest of all plants to grow. But get beyond the basics and folks often run into difficulty with species like broccoli and cabbage. The high rainfall/humidity and frequent warm spells experienced here during the growing season often lead to serious pathogen problems, dooming my garden in years past. However, this winter, thanks to a couple of new cultivars, ‘Capture’ Cabbage and ‘Burgundy’ Sprouting Broccoli, I’ve enjoyed a plentiful supply of tasty crucifers!

‘Capture’ Cabbage, developed by Bejo Seeds of California as a mid-season “white” fresh market cabbage for the South, has been an outstanding performer in my garden this year. Touted as highly resistant to Black Rot and Fusarium Yellows (by far the two most devastating pathogens of Cabbage), I had to try it for myself. I planted seeds 24” apart in my standard 4’ wide x 8’ long x 12” deep raised beds filled with mushroom compost and aged pine bark. Seedlings were fertilized once about three weeks after germination with a general purpose 10-10-10 fertilizer. The plants that developed have been extremely vigorous (I’m glad I paid attention to plant spacing guidelines on the seed packet!) and have not shown ANY evidence of disease, even through an unusually warm and wet winter that would have hammered older susceptible varieties. My plants have begun to develop heads and should be ready for harvest and the kitchen in just a couple more weeks! If you’ve had problems getting a cabbage from germination to head formation and harvest without serious disease pressure, give ‘Capture’ a try next fall!
‘Burgundy’ Broccoli in the author’s raised bed garden.
‘Burgundy’ Broccoli, developed by Elsom Seeds in the United Kingdom, is a unique variety sure to turn heads in your garden. True to its name, the prolific florets are a deep, purple color. Though the central “head” on ‘Burgundy’ is quite small, that’s not the primary feature anyway. Considered a “sprouting” broccoli, this cultivar puts out an abundance of side shoots that make ‘Burgundy’ sort of a cut-and-come-again broccoli, allowing for a long harvest window. Another advantage from a disease avoidance perspective is the short maturity time (the time from planting seeds to having harvestable shoots) of around 40 days! For perspective, a “regular” heading broccoli has a maturity of around 60 day, lots more time for problems to happen. In the same growing conditions described above for cabbage, ‘Burgundy’ performed amazingly well for me, growing strong, healthy stalks, large, unblemished leaves and an abundance of purple shoots with a nice flavor profile!
If you want to enjoy homegrown broccoli and cabbage but disease pressures have made your previous efforts unproductive, give ‘Capture’ Cabbage and ‘Burgundy’ Broccoli a try! These two selections have made it easier than ever to enjoy unique, homegrown, healthy cruciferous veggies. Keep these and other quality, disease-resistant cultivars in mind when planning your winter garden in 2020!

Gardeners have always known, down to their bones, that getting down and dirty in the soil is good for you. My grandmother was a staunch believer in the beneficial, calming effect of pulling weeds and digging in the garden when she was angry or frustrated with life.
Pulling weeds, digging up plants, planting new plants and seeds, mixing in good compost to a new landscape bed – these are joys that bring gardeners into intimate contact with soil and all the abundant life within. Gardeners love that smell of good fertile soil. As do nature lovers of all sorts. Hikers love the earthy smell as they tromp through the woods – especially after a nice rain when the fragrance is especially fresh and sweet.
What causes the aroma that we are experiencing? Much of it is bacteria. Good bacteria. Healthy soil is a complex ecosystem containing a great biodiversity of species of plants, fungi, animals and bacteria. And much research is being done to identify and learn about the thousands of species living under our feet.
Scientists are now suggesting that a fatty acid found in the soil-based bacterium Mycobacterium vaccae may alleviate stress and stress related disorders in humans. Gardeners have always known there was something about the soil that was good and healthy for us. Now, we have the science to back it up!
Happy Gardening!
Recently, I received a call about a garden not producing the way it used to. After speaking with the homeowner, I decided to take a visit to see what was going on. On my visit, I could see that the tomatoes were stunted, yellow and wilting, the squash plants were flowering but not setting fruit, and the okra was stunted. After digging up some of the sick plants and examining the roots, the problem was as clear as day…root-knot nematodes.
Galls on roots from root-knot nematodes
Root-knot nematodes are microscopic, unsegmented roundworms that live in the soil and feed on the roots of many common garden plants. Some of the most commonly damaged crops are tomatoes, potatoes, okra, beans, peppers, eggplants, peas, cucumbers, carrots, field peas, squash, and melons. Root-knot nematodes enter the root and feed, causing knots or galls to form. These galls are easily recognizable on the roots. If you’re inspecting the roots of beans or peas, be careful not to confuse nematode galls with the nitrogen-fixing nodules that are a normal part of the root system. As the nematodes feed, the root system of the plant becomes damaged and the plant is unable to take up water and nutrients from the soil. As a result, the plant may show symptoms of stunting, yellowing, and wilting.
What can I do about nematodes?
There are currently no nematicides labeled for use in the home garden but the best means of root-knot nematode management involves using a combination of strategies that make your garden less susceptible to attack.
Grow Resistant Varieties
Some varieties of crops are resistant to root-knot nematodes. This means is that a particular nematode can’t reproduce on the plant roots. When buying seed, read the variety label. The label may have ‘VFN’ written in capital letters. These letters indicate that the variety has resistance to certain diseases: V = Verticillium wilt; F = Fusarium wilt; and N = root-knot nematode. It’s best to use resistant varieties when root-knot nematodes are present.

Sanitation
If you suspect you may have a nematode problem, be sure not to move soil or infected plant roots from an infected area to a clean area. Nematodes can easily be spread by garden tillers, hand tools, etc. so be sure to disinfect all equipment after use in problem areas.
Infected roots left in the soil can continue to harbor nematodes. After the crop is harvested, pull up the roots and get rid of them. Tilling the soil can kill nematodes by exposing them to sunlight.
Cover crops and Crop Rotation
Cover crops and crop rotation isn’t just a concept for farmers…gardeners need to implement the same practices! While this may take some planning, it is the most effective way to reduce pests and diseases.
Cover crops are crops that are not harvested and are typically planted between harvestable crops. They help improve soil quality, prevent soil erosion, and help control pests and diseases. Selecting cover crops that aren’t susceptible to root-knot nematode attack is key. When growing a cover crop that nematodes can’t reproduce on, populations should decline or not build up to begin with. Grain sorghum and millet can be planted as a summer cover crop and rye in the winter. French marigolds have been shown to reduce nematode populations as well.
Another simple way to manage root-knot nematodes is by crop rotation. Crop rotation is the practice of not growing crops that are susceptible to nematode attack, in the same spot for more than one year. Crops that aren’t susceptible to attack are cool season crops in the cabbage family such as broccoli, cauliflower, Brussels sprouts, collards and kale.
Root-knot nematodes can wreck havoc on a garden so it’s important to take the necessary precautions to avoid them. It may require planning and patience but it will be worth it in the long run!
