Listening to your landscape

To have a more sustainable landscape, you need to listen...

As a long-time gardener with a masters degree in botany, I was certain that I could garden in north Florida when my husband and I moved here in 2004. I've told this story before, but I was shocked and surprised at how wrong I was. Some Florida gardening truths were quickly discovered like how tulips don't grow well here, not even as annuals, because our winters include warm spells so the soil doesn't stay cold enough. Other revelations have taken more time...

Tropical sage in the herb garden by the kitchen window.

Listen to the birds & bees

Tropical sage (Salvia coccinea) has monopolized much of my herb garden. I transplant some of it from this location when I plant basil, dill, or one of the other annual herbs, but mostly I leave this native volunteer in place because it attracts hummingbirds, butterflies, several types of bees.

I started the herb garden years ago by ripping out the tea roses and various non-native shrubs that were not doing well in this WSW-facing wall. At first everything was in its assigned place, but when the sage arrived, everything changed. I listened to the birds and the bees who needed this beautiful native more than I needed a neat garden.

Integrated pest management in the edible garden

Squash borers: Take action before they do damage.

I ended up with some volunteer butternut squash vines from kitchen scraps buried in the garden. Normally, I would not be growing them during mid-summer, but we'll see how they do in our hot summer weather.

One action item is to bury the base of the stems and then again along the vine in several places. Then even if the borer moth finds a place to lay her eggs and her larval offspring hollow out the stem, the whole plant will not have to depend upon that one section of stem for water and nutrients. It will have alternative roots. You really really don't want to use any poisons around squashes because each female flower needs to be visited by 7 or more pollinators to ensure fruit production.

Bury the base of the squash stems with compost and mulch with pine needles to keep squash borer moths away.

Then bury the vine at several additional places along its length.

Summertime, summertime...

Is it spring or fall?

Several years ago, I purchased this native fall-blooming aster, but each year it has bloomed in both the late spring and early fall.  Its breaking of bud dormancy may be caused by the same length of day as its correct blooming time. Whatever its problem, we do enjoy its surprise show each June.

Kohlrabi: a versatile cole crop

The weird stem enlargement is about the size of an apple.

Kohlrabi (Brassica oleracea var. gongylodes) is one of the many cole crops (cabbage, kale, collard greens, Brussels sprouts, broccoli, cauliflower, and more), which have all been bred from just one plant species. Kohl is the German word for cabbage—hence they are the "cole crops" and why cabbage salad is called cole slaw. The word kohlrabi means cabbage turnip in German, which makes a lot of sense because of the size and shape of its stem enlargement.

Because kohlrabi is easy-to-grow and has few pests in an organic garden, helps to explain its recently gained popularity with farmers markets and local food groups. It has been grown as a crop in Europe for centuries. Grown for its weird Sputnik-shaped enlarged stem-bulb with leaves sticking out at odd angles. You can consume both the enlarged stem and its leaves.

Remarkable resurrection ferns

Resurrection ferns dried and hydrated.

Resurrection fern (Pleopeltis michauxiana) and tropical resurrection fern (Pleopeltis polypodioides)

While I'd seen spare populations of resurrection ferns when I lived in Maryland, I really became aware of them when I read "Light a Distant Fire," an historic novel about Osceola and the Seminoles by Lucia St. Clair Robson. She wrote about how the scouts could disappear into the ferns on the live oak branches. After we moved to Florida, I came to see how this could be accomplished.

This is a true fern that reproduces via spores, but it is also an epiphyte or air plant. It does not need to be in contact with soil to live. It derives its needs from the air, especially the humidity and dust that it carries.

The common name of resurrection fern is due to its ability to lose 95% of its moisture, stop its photosynthesis, and go into a type of suspended state when it appears to be dead. When it rains or when the humidity becomes high enough, the fronds unfurl and turn green in a matter of hours. Hence the name resurrection fern, because it arises from the dead.

Winter: a good time to remove invasive plants

Wedelia or creeping oxeye daisy (Sphagneticola trilobata): a beautiful invader. 

Less lawn...

When we moved into our house here in North Florida, we let several areas of lawn grow out. I've written about this several times. See From lawn to woods: a retrospective, for what has happened out front.

Here's the other half of the story. Our 1.5 acre lot is long and pie-shaped. Out back is a narrowing strip to the lake. We decided early on that we'd not continue to mow this whole area and just leave a pathway that could be mowed with one trip down and one trip back on the riding mower. The area opens up by the lake, so there is more  mowing to do down there.

A wish for a greener 2015

I wish you and yours a wonderful and bountiful New Year!!

Winter vegetables

Here in Florida, even here in North Florida where we receive several killing frosts each winter, we can grow most cool weather crops right through the winter. In most of the country, gardeners spend winter wishing they could garden, while we enjoying our "Salad Days."

One of the main reasons we wrote "Organic Methods for Vegetable Gardening in Florida" was to alleviate frustration of gardeners new to Florida trying to use their old, general garden books written for Anywhere, U.S.A. They just don't work here.

Growing some of your vegetables is good for you and your family, plus it helps to make Mother Earth a little greener.

Speaking out

Senator Rob Bradley and me.

The 2014 Clay County Delegation hearing

Each year the 3 elected officials to the Florida legislature representing Clay County—a senator and 2 representatives—hold a hearing before the legislative session begins. This year the committee work begins in January and the general session begins on March 4th. (The only date during the year that calls for action. Get it? March 4th.)

After introductions of the delegation members and their staff people, the normal agenda was interrupted for a heart-rending testimony of a mother holding her child with brain cancer pleading for more freedom in choosing medicines including restricted substances.

Then came the parade of the local elected officials from the county, the 3 incorporated towns, the school board, the clerk of court, and the supervisor of elections. They all made cases for more money for their various projects. The one surprise was the clerk of court's problem of the lower crime rate meaning less money in fines that are normally used to run the court.

Yard critters

A green treefrog (Hyla cinerea) jumped out of the beggar ticks (Bidens alba) that I had pulled from the front garden.

A bagworm (Oiketicus abbotii) is overwintering on a beautyberry bush.

Managing exuberance carefully

I allow some beggar ticks (Bidens alba) and snow squarestem (Melanthera nivea) to grow in restricted areas to attract all those pollinators. But in the fall, I harvest those that have escaped to other places in the landscape to reduce the population and weeding the next year, at least to some degree. So last week I started pulling and a cute green treefrog that was using these stems for shelter jumped out of the cart. And the frog is just the wildlife that is evident. There could be hundreds of bugs snuggled inside these stems for the winter. Instead of leaving these stalks out with the yard waste, I add them to various brush piles, so those insects will have a chance to make it through the winter. The songbirds also use the brush piles for shelter, so they may appreciate the seeds, and maybe even some of those hidden bugs. 

Nearby, I spotted this bagworm (probably Oiketicus abbotii) hanging from a beautyberry branch. This moth is different than most, in that it gathers plant parts to stick to itself as a caterpillar to build protection. When its ready to pupate, it glues its portable shelter to a secure location and seals itself inside. When the female reaches the adult phase, she will be flightless and will emit pheromones to attract males. When a male arrives, they mate inside her sack where she lays her eggs and dies. The new larvae feed on her remains and other food that she's stored there. When ready, the new larvae head out on their own, often on a long strings of silk that balloon in the wind so the larvae swing away from each other. Isn't Mother Nature amazing?
