Modern refrigeration as we know it is one of the most critical inventions in the last century because they improve your access to safe food supplies. Fayetteville is known as a food desert* and when one is without refrigeration this fact is exacerbated to a potentially intolerable level. About two weeks before Christmas my refrigerator decided to die on me. I knew something was wrong when I opened the freezer to find all of 2016’s frozen harvest defrosted completely. Since I did not know how long it had been that way unfortunately there was no good reason to try and salvage most of it. Once I did notice that there was a problem, the first task was to verify that the refrigerator was actually broken. I raised the cooling settings to maximum and then placed a thermal sensor in the freezer and the refrigerator section and afterwards checked them every hour for six hours. When you change the settings of a refrigerator it takes 24 hours for the settings to take effect so six hours was a good time frame to estimate the refrigerator’s functionality. At the end of six hours the fridge was cool at about 50 degrees and the freezer was at roughly 48-49 degrees; the normal temperature should have been 32-40 for the refrigerator and 30-32 degrees for the freezer. While looking for the unit specifications I found that the refrigerator was made in 2014, and thus it had depreciated enough that repair would cost more than replacing the unit. The next step was to clear the refrigerator of anything that posed a health threat via spoilage or contamination. Nothing in the freezer was salvageable so everything that was not packed in oil went out to the compost pile, you could say that the decomposers in the pile got big Christmas present this year.
The process was repeated for the refrigerator section though a lot of things in the refrigerator were just fine at 40-50 degrees. A good example of things that did not need to be thrown out would be your basic condiments. For example, mustard, soy sauce, siracha, non-sweet salad dressings, and anything that is acidic such as pickles were relatively save in the short term. Eggs, butter and, cheese were also alright because they could withstand a wider temperature range than milk, yogurt, cut fruit and vegetables and fruit juices which had to go in the cooler. Meat products were handled cautiously because at 45 degrees it would not take long for food-borne microbes make them hazardous. Any meant brought in had to be cooked the day purchase and consumed within 48 hours. I found that it takes a 20lb bag of ice to effectively cool an 18 cubic foot capacity refrigerator per two days. The trick was to use plastic containers to spread the ice around and ½ to ¼ fill the vegetable crispers full of ice. This kept the refrigerator at around 43-46 degrees which reduced any further losses of food. I also used a 48 quart cooler with 10 pounds of ice to super-chill what absolutely needed to be cold**. It was a good thing the refrigerator failed during winter because if it had it done so during summer it might have been impossible to keep anything cold. So life settled in to a pattern, every two days or so I would go out on an ice-run, and while there I would buy the fresh foods needed to make two days’ worth of meals. It briefly became a normal aspect of life that everything had to be cooked fresh every second day. This was made possible by taking normal recipes with the amount of ingredients reduced by half. The half-scale style of fresh cooking meant that I made twice as many trips for food but the cost of food remained the same overall.
The biggest lesson learned was that it is very possible to have a fresh and organic food diet that was nearly vegetarian without the presumed big price tag. It took some planning to have a menu that would not get boring; my diet varied a bit for two weeks with the following selections; Kale-bean soup, Grilled vegetables with basmati rice, Tuscan Stew, Sautéed yellow squash with sweet onions, traditional hearty stew, Broccoli Rabe with fresh garlic over penne pasta, Steamed broccoli served with Turkey drumsticks and basmati rice and a rich mushroom gravy. I will admit the aforementioned list is just dinner, I kept lunch and breakfast limited to one-off dishes that were made and consumed on the same day. The point is that you can eat fresh, but creativity is critical to a reasonable fresh diet, and that starts with you determining what you do and do not have a taste for.
*The USDA has a food desert locator; https://www.fns.usda.gov/tags/food-desert-locator
** Things such as cut vegetables & fruit, milk, dairy products, and fruit juices, opened jams and jellies and, meat should be stored in the cooler.

Welcome back to another fine episode of Lost In The Farmers Market, this is our first episode of spring 2016, and you can bet there is some good stuff planned for this one. You have to love how spring came so fast though; it was not long ago temperatures were dipping into freezing every night. It appeared as if nothing seemed to be growing except the winter weeds and then suddenly we had a bunch of hot days and everything was dusted in a patina of yellow pollen from the pines. As if teasing all those nice seed catalogs and garden supply books started showing up in the mail and you placed your orders and the waiting game started. We all looked outside and relished the few warm spring-like days and then the weather started to act like summer sort of and we had to hold onto the urge to do anything because we knew it’d cold again. But then the miracle happened, all that stuff you ordered in February showed up in March!
|Oh yes it’s very much like this.|
So you have the goods, and well the weather turned sideways…again. But there is good news, the unofficial final killing frost date is Sunday April the 31st and that means in short order it will be very safe to start putting out your tomatoes or planting your warm-season plants directly. But of course not everyone knows what to do this time of year so of course as the first order of business I’m teaching this class.
Jump-Start Your Garden
Sunday April 10th, 2016 2:00-4:00pm
At the Museum of the Cape Fear Historical Complex
801 Arsenal Avenue Fayetteville NC 28305.
You can sign up for this class here: http://www.meetup.com/SustainableNeighbors/events/229870215/
Walk-ins are welcome.
This class is hopefully the start of a monthly series (2nd Sunday of every month) and it comes about three weeks before the Sustainable Neighbors Urban Farm Tour which is slated for the First May 1st, 2016 between 2:00-5:00pm. The garden tour locations will be announced as I verify who is willing to host a location. So yes spring has sprung and there are all sorts of good stuff going on. Also there is the City market Meetup which happens weekly and
The City Market
325 Franklin Street, Fayetteville NC
Below you will find a list of what is most likely going to be available at the market; I should note that this is the last week that I sell soup-kits. This is mostly because I require the table space for warm season crops and honestly soup isn’t as great when it’s hot out. I should have tomatoes and or warm season items in a week or two depending on what the current weather pattern decides to do.
8x Soup Kits, $5.00 (Celery, Carrot, Red Potatoes, Onions, Purple top turnip and a parsnip)
8x Rouge D’hiver Lettuce, $3.00 (Romaine Type Heirloom)
8x Napa Cabbage, $3.00 (Asian Cabbage, Heirloom Type.)
6x Dinosaur Kale, $3.00 (AKA Tuscan Kale, good for kale chips)
6x Swiss Chard $3.00 (Bright Lights Mix)
With all of the aforementioned covered, now I move onto the main topic. For you regular readers you might remember the image below from January. This is a Crosby’s Prolific Aloe, and this image was again taken of the plant in January. As the weather has stabilized I was preparing to bring it out to the deck so that it could get some additional sun and hopefully bloom and I noticed something was wrong.
|Aloe x. nobilis – Crosby’s Prolific Aloe|
The fact is that succulents and cacti are very dramatic when sick and you can easily spot a sick succulent in a row of identical ones because they are very apparent. Since succulents can’t exactly wilt like a bedding annual and can be scarred by injury for years when they suddenly collapse it means something is terribly wrong. So you have what I found on the growing tray a few days ago.
|This is incredibly bad.|
This aloe is suffering from a sickness that is commonly fatal to aloes because it is so difficult to detect before the plant has gone soggy. The sickness is commonly called Root Rot and it is caused by one of two types of water mold both tend to strike as a result of over watering. The two common culprits are called Pythium and Phytopthera and both are hydrophilic in nature in that they need a wet environment to attack your plants. For note I keep my aloes very much on the dry side so I suspect this aloe got attacked because fungus gnats are known to spread root rot as the root rot organisms can live on the feet of fungus gnats. Why root rot randomly attacks healthy plants is unknown, but it’s always severe, some plants lose half their mass and recover, others seemingly turn into a puddle of slush overnight. Literally for succulents root rot is as severe as Ebola is in humans. Generally treatment isn’t worth doing but if it’s a special specimen like this Crosby is, then the first step is to remove as much infected tissue as you can.
|Opportunistic fungi and diseases move in after root rot has done it's worst|
|Mostly cleaned this aloe still is a mess.|
In the case of my aloe, that means removing any and all collapsed stems. Since most of the connective tissues are pulped by the disease this should be easy but try not to touch the healthy portions of your plant after you’ve touched diseased portions. Cut away as much as you can and then wash your hands and any tools you may have used with rubbing alcohol. Next inspect the healthy portions; in the case of my aloe the one healthy stem is also being attacked. Since this is a specimen plant, I will go ahead and cut the healthy stem off, then peel away the dry papery coverings over the stem. The next step is to cut ahead of the encroaching rot and make a cut into healthy tissue with a clean pair of scissors or a very sharp knife.
|The rot has attacked this stem also but the crown in this case is well above the damaged area.|
|With the papery sheaths at the leaf bases removed it's clear that the rot does not go all the way up.|
|A simple single cut with a clean pair of scissors and now we have a potentially viable cutting.|
It is possible this cutting may make it but there is one more aspect to after-care, this cutting should be allowed to air-dry for a few hours, then get dipped in rooting hormone and allowed to form a callus at the end of the stem. The callus forming procedure can take a few days, but make sure to seat the cutting so it’s bottom faces down like shown. In few days the cutting will either collapse due to rot or begin to form roots, at this point it’s a 50-50 chance depending on how well you maintain sterility during the cutting procedure. If it survives, a few days place the cutting in a small pot with sterilized potting medium and water sparingly. Within a month the cutting will either grow roots and, continue on or the disease will take its toll. As for the remains of the plant and its old potting soil, dispose of that in in the compost and do not use any compost from your compost bin for at least six to eight months.
|The cleaned cutting being dipped in rooting hormone after being allowed to dry a few hours.|
|The cutting is placed upright in a jar for a few days to allow a proper callus to form and to impede the progress of any surviving root rot pathogens.|
From the point in the last picture it become a waiting game to see if or if not the cutting recovers. Either way I hope this helps some of you succulent and cacti growers out there.

Welcome back to another installment of Lost In the Farmer’s Market. This is the February post and for the purposes of getting back on track for March in a twice-per month schedule the two posts containing haworthia and gasteria will be combined into one larger post for your reading enjoyment. In March I will begin discussing all things late winter and spring so hold on to your hats…it’s going to be good!
Few garden enthusiasts realize that most of our garden species come from a limited number of plant families. For instance the Aster family contains the daisies, marigolds, Calendulas, Dandelions, Coreopsis, Echinacea, Lettuce, Radicchio, Rudbeckia, Zinnia and of course the Asters. In the same light the Aloe grouping has three major branches to it’s family tree, in my last post I covered the Aloe group but in this post I will be talking about the Haworthia and Gasteria branches. I have to admit that the Aloes are better known because of course we see their most famous representative (Aloe barbadensis/vera) in a wide variety of skincare products and some health beverages. In interesting contrast, the Haworthias are no less varied in shape and form and actually are more cold tolerant. To an extreme for a succulent, Gasteria are even tougher than the haworthias and can survive long periods of complete neglect as long as they get some sunlight.
As noted before the first rule of succulents and cactus is that “All cactus are succulents, but not all succulents are cactus.” This saying means that basically Cacti have a very specific biology, and thus when dealing with a succulent plant it’s smarter to call it a succulent until you know absolutely what you are handling. Aloe, Haworthia and Gasteria are all succulents because they lack spines, whereas cactus will have several types of spines as a form of self-defense. I am simplifying a bit but then this is not a hard botany article so my light-weight definition is reasonably accurate. As for haworthias which consequently have no common name, it’s best to think of them as aloes with much smaller leaves and a habit for growing faster and producing offshoots quicker. They are as a whole somewhat more tolerant of moisture but I would not assume that to mean you water them as often as a house plant such as a philodendron. Haworthias can handle temperatures as low as 28 degrees as long as they are not exposed to chilling winds or have wet foliage but frozen soil will kill a haworthia. Make no mistake, if you leave a haworthia outside in winter where the temperature drops below freezing you will probably lose the plant. If kept in a sunroom and covered over with a thin plastic drop cloth it is likely that a haworthia will survive the winter without needing to come indoors barring any exceptionally cold weather.
|Haworthia coarctata – Dragon Haworthia|
|Haworthia cuspidata – Star-Window Plant|
|Haworthia cuspitata – Star-Window Plant (red type)|
|Haworthia margaritifera – Pearl Plant|
|Haworthia miribilis – Wonderful Haworthia|
|Haworthia venosa subspecies Tesselata – Tesselated Haworthia|
|Gasteria liliputana – Dwarf Ox Tongue|
|Gasteria minima – Miniature Ox Tongue|
|Gasteria maculata – Ox Tongue|
|Gasteria bicolor – Bicolor Ox Tongue|
The next few plants answer a question that all you house plant fans out there may have wondered, ‘if those three plants are in the same family, can they produce hybrids?’. The answer is yes as they can with careful management produce viable hybrid offspring, thus far I have no aloe-haworthia or haworthia-gasteria crosses but the following are gasteria-aloe crosses that have produced an interesting variety of forms and colors.
|Gasteraloe hybrid – “Green Gold”|
|Gasteraloe hybrid – “Green Ice”|
|Gasteraloe verrucosa – “Radiance”|
|Gasteraloe verrucosa – “Flow”|
Now that the main topic has been handled stay tuned for our next article in two weeks where I’ll be talking in brief about the Rhipsalis family and a bit about spring preparations. Before I go however I do have to talk in brief about the City Market and the Better Health Market.
Better Health Market
1224 Bragg Boulevard, Fayetteville NC
The City Market
325 Franklin Street, Fayetteville NC
I bring up both markets because as of this week I’ll begin offering my first spring plants as we are just about to enter the month of March and the time when most gardeners in our region really begin to consider their options for the coming warm season.
