A mild winter so far

Returning home from winter break travels, I was surprised that we'd still not had a hard freeze in the Piedmont. Some of the camellias near the house are loaded with lovely pink and white flowers -- the white-flowered ones are a treat because they're almost always browned by freezes!

The cilantro and arugula are still looking great - both can withstand light frosts, and maybe more if they've been gradually exposed to lower temperatures. (The cilantro is in a glazed ceramic pot, while the arugula is growing as a big patch in the satellite garden.)  The parsley is still looking good, too, of course, and the French sorrel is putting out new leaves, too (apparently the deer haven't been back recently).

On my walk this afternoon, I saw a large patch of mustard greens (similar in cold hardiness) looking good, too. It'll be interesting to check out the kitchen garden next to the visitor center (at the botanical garden where I work) to see how the snow peas are faring!

In the mountains, the weather has been a lot colder, temps into the lower 20's.  It'll be interesting to see how the greens in the raised beds there have fared on our next trip.

A compost turning = happy gardening in 2013!

The old compost pile by the shed was last turned in midsummer.
Last summer I turned this compost pile as part of the shed-moving project, and I've continued to add alternating green and brown layers* to the top since then.

Now, it was time to turn it again to access the bottom of the pile, which I guessed would be finished by now. I also had some old, mostly composted arborist woodchips to mix in with the unfinished compost to add some extra nutrients and more volume.

I cleared out the space for the new pile where I'd recently worked down to the bottom of my last compost pile.

At the bottom of the new pile a layer of leaves and pine
needles topped with a layer of the old woodchips.

Layering the new pile


Once a three by five-foot rectangular area was cleared and smoothed, I put down about a five-inch layer of leaves and pine needles. There is an unending supply this time of year. I added about a two-inch layer of chips and then a three or four-inch layer from the compost pile.

From there on, I alternated the materials from the compost pile with thin layers of old chips. By the time I was halfway through, the old compost pile, the compost was mostly finished. Yay! When it was clear that all the compost was finished, I stopped.

Finished compost is stored in a bin.

Storing the finished compost


I had a fair amount of finished compost from the bottom of the pile to store. I had dumped out the last of the old compost from the bin onto one of the layers in the new pile because it had dried out. I rinsed out the bin with rain barrel water and then shoveled in the fresh compost and put the lid back on the bin. Beautiful.

But I had more than the bin would hold, so I shoveled the rest of it out from its old spot. After I had filled the old wheelbarrow, I piled the rest on the ground in a holding spot while I cleared out a good storage spot.

I don't smile when I hit Smilax rhizomes even if they are red like this one.
I found a vigorous greenbriar (Smilax spp.) rhizome under the old compost pile and removed it. At least there are no prickles on the underground portions. This particular root was about ten feet long before I cut it off as it went under some nearby trees.

Oooh, I hate this pesky native plant and have spent many hours wrangling with it. I have the scars to prove it. Clawed by the cat-briar!  But this time I caught it before it sent up its prickly shoots.

Readying the storage spot for the finished compost.

Once I'd cleared and leveled the spot, I again laid down a good six-inch layer of mostly pine needles (where the leaf rake is) and then shoveled the compost from the pile (to the right of the rake in this photo) on top of it and dumped the wheelbarrow load, too. I removed any worms I saw from this pile and added them to the new compost pile. I don't want them to over-work the finished compost. Then I evened out the top of this new pile and covered it all with a thick layer of leaves and pine needles. I also covered the new pile with leaves and pine needles and I won't continue to add layers to it. I'll let it mature.

This photo is taken from behind the shed. In the foreground
is the pile of stored compost under a cover of leaves; in front
of that is the rest of the old chips; in front of that is the new
pile & the yard waste barrel, which now holds the catbriar.
And at the top of the photo, two of my six rain barrels.

Whew! A good afternoon's workout and my spring garden plants will be happy to have it.

I estimate that this compost will be done in time for late spring gardening. Our last frost is usually around the end of February, so mid-March is the time to set out the tomatoes. That way we can harvest a good crop before the summer heat stops them. It's time to start those seeds now. (More on that later.)

Until then, I'll use the compost for potting up houseplants, container gardens, seed starting, and garden bed building for cool-weather vegetables. I'll also use some compost as top dressing around the driplines of relatively newly planted trees and shrubs around the property to encourage outward root growth. Wide-spreading roots are more drought tolerant and more wind tolerant. Who wouldn't want that?

Alchemists would be envious of my Black Gold!


For centuries alchemists unsuccessfully tried to turn base metals such as lead into those noble metals (gold and silver) with magic potions and weird spells. We gardeners take waste products such as dead leaves and kitchen scraps and Mother Nature supplies the magic to turn them into compost, our black gold--no magic words are needed. Isn't that cool? Do you have your own Black Gold mine?

Two weeks in the Caribbean

St. John view
St. John view
A couple of weeks on two relatively quiet Caribbean islands has been largely free of gardening observations. I didn't see many vegetables or fruits of any sort being grown on St. John, US Virgin Islands, aside from our friend's plantings (she's been planting tropical fruits such as bananas, mangos, and papayas, as well as sowing lettuce and growing tomatoes). The island is largely dependent on imports from surrounding islands and the mainland for most fresh provisions, apparently. There seems to be a small trend towards establishing kitchen gardens (according to a tourist booklet on the plane) by some resorts in the UVI's just to serve their own restaurants. I can certainly see why this would have appeal! St. John is quite dry so it's challenging to have enough water available, with cisterns being widely used for water-harvesting.

The prime attraction on St. John is the vast expanse of national park, both above and below the sea. Snorkeling is fabulous, as are the beaches and hiking.

Our second week is being spent on Dominica, a largely 'natural' island of rugged topography and remarkable vegetation. In coastal areas, agriculture is practiced largely in small-holdings of bananas, cassava, and taro, punctuated by groves of oranges, grapefruit, and tangerines.

I bought some "spinach"--actually an amaranth (callalo) - not the New Zealand spinach I was remembering (I actually recognized the plant as amaranth, but didn't remember exactly what NZ spinach was) - carrots, lettuce, onions, and "seasoning peppers" from a woman near our cottage, and chatted with her a bit. She grew vegetables all year round in raised beds bounded by metal roofing. Her chickens provided the fertility for the nice-looking soil.

We saw a similar plot on a hike up into the surrounding hills (of banana plantations) - the young woman tending this market garden was more ambitious. She even had a bit of broccoli growing - amazing for this warm climate.

Winter Solstice and more...

The Mayan Calendar ends 12/21/12 6:12 am EST.
Winter solstice has been a cause for celebration (both pagan and religious) since man's earliest days for now is when the days start to get longer. And isn't that reason enough?

This year the day has new meaning, though, since the experts tell us that the Mayan calendar, which has been in effect for more than 5,000 years, will end.

Over on the Florida Native Plant Society blog, I posted a plea to plant a tree, because when you plant a tree, you believe in the future. So if the world does not end as predicted, it will have been because all those gardeners planted so many trees that the future just had to be there for them.

Read more of this post here.



Broccoli harvest

In the garden, we've been enjoying all the cool weather edibles, particularly the broccoli. Once we harvest the main head (curd), we leave the rest of the plant in place so it will grow new, smaller curds which we'll also pick, the side curds open much more quickly than the main curd, so it's important to keep an eye on them or you'll miss the harvest window.

Eventually, when the next batch of broccoli is producing, I'll let some of these plants flower, so the mid-winter butterflies and bees have a reliable supply of nectar.

After the main curd is harvested, we also use the leaves, which are somewhat sweeter than cabbage leaves, in soups, stews, and salads.
After the main head is harvested we leave the plant in place for more curds and for the leaves.

Chasing the chipping truck


The other day this truck, a chipper and its truck and a stump grinder rumbled down our street. My old pile of arborist wood ships was getting low and it was old enough that it was mostly compost anyway. So I walked down the road and asked what they were going to cut down and grind up. It was a mature and healthy hickory, which was dropping nuts on the lawn between the house and the lake. So these homeowners thought it was too messy and spent big bucks to have it removed. Personally, I would have removed the lawn and planted native understory trees and shrubs, but it wasn't my choice.
The tree guys said that they'd be done with the chipping around lunchtime. I cleared out the rest of the old pile. About ten big cart loads later, I was thinking that the pile wasn't really all that small, but now I have a new pile of wood chips, leaves and spanish moss.  I hope that there were no bird nests.

Two days after the pile was dumped, it was hot. You can see the steam rising in the morning sunlight. The odor is almost a minty smell. The fence out here is rigged so that one post comes out and the rails removed so the pile can be dumped behind the fence. It works very well.
I've lost count of how many piles of wood chips we've received over the years. They've all been absorbed into our yard in one way or another. Here's my post on chips Follow the Yellow Mulch Road.

Coral berry (Ardisia crenulata)


Coral berry

I found some coral ardisia in a wooded area out back. Although it's a lovely plant, which produces oodles of red berries perfect for holiday decorations, I yanked it out. It's highly invasive in Florida. I don't want to be part of the problem. Here's the FLEPPC (Florida Exotic Pest Plant Council) data on this plant.

I could have used it for building a wreath, but I'd already done all the wreath building I was going to do. So it went in the trash--not the yard waste. See my post:  Recycled Christmas Wreath.


I wish you and yours a very Merry Christmas and a Greener New Year, if the world is still in tact. ;-)

Scrubjay Trail Winterfest

A mocking bird surveys its space. Does it see that bug?
I did see some scrub jays, but they did not pose as well
as this mocking bird.
I attended the Scrub Jay Trail Winter Fest in Clermont, FL on Saturday. What a great event and the weather was fantastic. All for a good cause: the preservation and conservation of the habitat in and around the Scrubjay Trail.

All day long wonderful musicians filled the air with festive melodies, people took rides on the big cart behind two gorgeous work horses, kids were entertained by Ranger Rick and a slew of activities, people bid on the vast array of silent auction items, and more.

And oh yes, I was there talking to folks about my books, Sustainable Gardening for Florida and Organic Methods for Vegetable Gardening in Florida and also about the upcoming Florida Native Plant Society's conference in Jacksonville in May.
A beautiful lake with the classic Florida afternoon cloud show.

It's inspring to see the huge amount of effort put in by all the volunteers to produce such a top-rate event. People of all ages were educated and entertained and how fantastic to spend the day outside communing with Mother Nature. And of course, all to benefit the Scrubjay Trail in Clermont, FL.

So do you have a pet project that you'll be working on for Mother Nature in 2013? She needs all the help we can provide.

Bokashi Composting, a fast, anaerobic, fermentation process


Gainesville Compost Chief Engineer & Inventor Steven Kanner
mixes bokashi grain into UF Krishna Lunch food waste.
A guest post by Chris Cano

(I ran into Chris recently at Porter's Community Garden. You can read about this at The Gainesville community behind Porter's Garden. He talked about this different type of composting, so I asked him to educate us. Thanks, Chris.)

Upon running into Ginny at Porters Community Farm, I was excited to share with her about our Gainesville Compost initiative, particularly about a new food scrap fermentation solution called bokashi which we have been experimenting with at the Porters plot.

While the Gainesville Compost initiative collects hundreds of pounds of food scraps per week, we have normally handled this by way of traditional pile composting and vermicomposting (using earthworms). Recently, we learned about the centuries' old Japanese bokashi method of composting, which uses anaerobic bacteria to ferment food scraps, thereby reducing odors, reducing the volume of waste, and preparing the scraps to be more easily digested by microbes in the soil or compost pile.

During last week's workday, while many of the volunteers planted fruit trees, we were working on another project: handling an impromptu load of approximately 1,000 pounds of cooked food from the University of Florida's popular Krishna Lunch program, which serves about 1,000 students a day on campus.

While we have handled Krishna Lunch's pre-consumer food waste for nearly a year, their post-consumer leftovers have been going to a pig farmer. On this day last week, the Krishna Lunch coordinator gave me a call with an emergency request: "We have 44 buckets of cooked food waste in buckets, is there anything you can do for us?" So we decided to help.

Our last bokashi experiment proved to be fruitful. The process, as described below, resulted in a 40-percent reduction in volume in one week, a 60-percent reduction in volume in two weeks, and a virtually odorless end product, which after one week in our compost piles has nearly decomposed completely.

To make/use bokashi:

1. Start with a grain substrate. In our case, we've collected spent grain from a local beer brewery.
2. Inoculate your grain with a culture of microorganisms commonly known as "Effective Microorganisms" or EM1. (We purchased our first batch, but now we are maintaining a culture for future use.)
3. After one week, mix the inoculated grain into a container of food scraps. We went with a ratio of around 1:10 parts grain to food scrap. Seal the container.
The liquid drained from the bokashi process
is a microbe-rich soil amendment.
4. Throughout the following week, you should drain the liquid, which can be used as a microbe-rich soil amendment. Draining the liquid helps to reduce the volume and weight of the material as well as prevent the process from going sour.
5. After a total of two weeks fermenting, open the container and you will likely notice a surprisingly odorless mix that has dramatically reduced in volume. You can apply this food scrap (which visually resembles its original state) to the garden by burying right in the soil, or to the compost pile where it will rapidly break down.

We are excited about using bokashi to improve our process. Bokashi has the potential to be a great urban composting solution (mainly because of its odor elimination), but also an amendment and soil builder for rural agriculture. In fact, we've got a waiting list of local farmers who are eager to try it.

Happy composting!

The Gainesville community behind Porter's Garden


I saw a notice on Facebook that Porter's Community Garden in Gainesville was looking for volunteers to plant donated fruit trees on Wednesday Dec. 5th. I was going to be in town for a couple of other meetings on that day, so I stopped by. What a great community project!

Intensively grown cabbage plants have
been mulched with straw.


The community behind the garden

The person who lives next to this plot donated use of the land and a greenhouse, which is still needs to be put together. The plot already had a water source, so it was a matter of clearing the weeds and bringing in some compost. A community fundraising effort raised $12,000 for expenses.

Ten 55-foot long rows are dedicated to raising food for St. Francis a nearby soup kitchen and homeless shelter. The goal is to raise one ton of vegetables annually for St. Francis and other local charities. In addition, six 4x8-foot raised beds have been constructed for families in this disadvantaged neighborhood. More will be constructed as needed to support the community.

The local Chestnut Hill Tree Farm donated $500 worth of fruit and berry trees, which was the reason for this planting session.

Florida Organic Growers (FOG)  

FOG, a non-profit corporation established in 1987, promotes organic and sustainable agriculture by educating "consumers, farmers, future farmers (children & youth), businesses, policy makers and the general public." Porter's is one of their projects.

Travis Mitchell, a UF alum in organic agriculture and FOG's community project coordinator, was being interviewed and taped for a radio show when I drove up. So I talked to the other volunteers and interns who were working.

After the interview, he explained some of the details of this project to me before getting back to work. If you look at the second peach tree photo, that large election sign will be painted over and posted here, so people will know what's going on.

Gainesville Compost

Also onsite were a couple of guys from Gainesville Compost, a pedal-powered community compost organization, which makes sustainable soil from food scraps collected from local restaurants and distributed to local gardens. They now have a Compost CSA! How cool is that? A CSA (community supported agriculture) is where clients pay up front for a season's share of a farmer's harvest. Here, clients pay for a season's supply of compost.

Chris Cano (on the right in the photo below), the CEO (Compost Experience Officer) of Gainesville Compost, remembered me from my presentation for Gators for a Sustainable Campus three years ago. (See my post on that encounter: Green Gators: There's More to University of Florida Gators than Just Football... )

Chris posted a good summary and history of the Porter's project on his website: Porters Community Farm: Help Fund an Inspiring Urban Farm in Downtown Gainesville. He also promised that he'd write a post as a guest blogger here about bokashi composting, which uses a fermentation process of some kind. I look forward to that.

Gainesville Compost is a company that ditributes food scraps from restaurants to gardens via their pedal-powered trailers. Chris Cano CEO is on the right.  On the left: Steven Kanner, a senior environmental science undergraduate at UF and Chief Engineer & Inventor at Gainesville Compost. Chris met Steven when he was developing his custom bike trailer business called Kanner Karts.
I enjoyed this uplifting side trip to such a green and sustainable community project. I loved running into Chris and that he remembered me from that stormy night at UF when I was sure no one would come. But 40 or 50 students cared enough to show up. As I said at the time, "meeting these enthusiastic students and learning about their initiatives, gives me hope for the future." So now it is the future, and look what I uncovered. How Cool!
