What better New Year’s resolution could there be than to start recycling and do our part to preserve our natural resources? By composting yard and kitchen waste, we can also get a jump-start on our spring gardening by creating your own mulch and fertilizer. Done properly, raw compost material can transform into nutrient-rich soil in just six weeks! A free source of “slow release” nutrients, compost also loosens tight, compacted soils and helps our often-sandy soils hold nutrients.
So what is compost? Essentially, it is what’s left of organic matter after it’s been thoroughly decomposed by microbes. Among the common compostable organic materials are leaves, grass clippings, twigs, pine straw, and vegetable/fruit peelings and coffee grounds. When using these items, alternate by using brown (leaves, straw) and green materials (grass clippings, vegetables) in the compost bin to provide adequate carbon and nitrogen. Table scraps containing meat, eggs or oils are not recommended because they can draw rodents and cause an odor. Eggshells are OK, but in general, use only kitchen scraps that are either plants or paper.
The organisms doing the actual composting are microscopic bacteria and fungi, along with earthworms. The microbes need water, oxygen and nutrients to thrive. Rainfall will provide most of the needed moisture, although you may need to hand water the pile on during dry times. For the best results, keep the pile moist but not soggy; if you pick up a handful it should not crumble away nor drip water when squeezed.
To move oxygen through the pile, increasing decomposition and preventing odors, turn the pile on a regular basis with a pitchfork or rake. Some companies sell compost bins in moving cylinders that can be turned with a handle. The process of decomposition will generate extreme heat (over 150°F in the summer) within the pile, which can kill weed seeds and disease-causing organisms.
Done correctly, composting does not smell bad, is very easy to do, and is a great way to do something good for the planet, your yard, and your wallet! Learn more about composting at this University of Florida Extension article.

The “new” or “Irish” potato is one of America’s most popular vegetables and a fine cool season crop choice for gardeners in the Panhandle.
The history of the potato is quite interesting. The potato was first domesticated in Peru between 3000 BC-2000 BC. Potatoes were first planted, where in states? Idaho, of course, as early as the 1830’s. By 1900, Idaho’s production exceeded one million bushels. Potatoes are diverse in appearance and uses. Potatoes are high in nutrition and have fewer calories than other starches such as rice, pasta and bread.
In Florida, potatoes can be planted in the winter or early spring. February 1st to March 10th is the prime planting range. As a general production rule, 100 lbs. of seed potatoes will typically yield around ten bushels. Be sure to use only certified seed potatoes for best planting stock. These can be found at most garden centers. For best results, select varieties recommended for North Florida like ‘Atlantic’, ‘Sebago’, and ‘Superior’ (all round, white potatoes). Also, ‘Red Lasorda’ and ‘Red Pontiac’ are viable round, red potatoes. Resist using potato stock bought from produce sections at grocery stores. Odds are, symptoms of a number of diseases will occur. For planting, each seed potato should be cut into smaller pieces, displaying two or more eyes. To prevent fungal pathogens, the most common culprit in potato production, use a light dusting of a fungicide to combating decay.

It’s best to plant seed potatoes in raised rows, where the height of the mound is 6 inches and the width is 1 to 2 feet. Row spacing should be at least 3 feet apart. The seed furrow should be 3-4 inches in depth, through the center of the row. Seed potatoes should be planted in 1 foot intervals. Cover, and water freshly planted rows. Fertilizing is key. One quart of 10-10-10 fertilizer for every 50 feet of row space is needed for the initial application. Through the season, for every 3 weeks, side dress the rows with a pound of 10-10-10 per 50 feet of row space.
Following these steps will ensure a productive potato crop. For more information please contact your local county extension office.

Raised beds are an excellent way to get started with gardening. Photo by Molly Jameson.
One of the biggest obstacles a vegetable gardener faces is how to supply crops with healthy soil that can support crop growth all season long. Many native soils in Florida are stripped of imperative nutrients that crops need to grow, are too compacted from vehicle and foot traffic, and are often too sandy to support soil life, which is very important for nutrient cycling, building soil structure, and combating pests and diseases.
One of the best ways a gardener can ensure a successful gardening experience is to build a raised bed garden. No matter your native soil type and existing conditions, raised bed gardens allow a framework for building nutrient rich soil that can supply crops with what they require to grow healthily and thrive.
Want to learn how to garden using raised beds? On February 5, from 6:00 to 7:30 p.m., UF/IFAS Extension Leon County is offering a Raised Bed Gardening 101 workshop as part of the Red Hills Small Farm Alliance’s Seven Days of Local Delights. This is a week-long annual celebration that includes educational workshops, restaurant partnerships, fundraisers, and more that supports the local food community and farmers in the Red Hills Region. This year, the Seven Days of Local Delights runs from Sunday, February 3 to Sunday, February 10.

At the Raised Bed Gardening 101 workshop, learn how to choose the best raised bed garden site location, basics of irrigation in raised beds, planting dates and plant spacing, the difference between treated and untreated lumber, how much and what type of soil to use, and other tips on growing food in your backyard.
There is no cost to attend, but please register on Eventbrite (https://sdldraisedbedgardening101.eventbrite.com). For more information, contact Molly Jameson at mjameson@ufl.edu.
Check out everything going on during the Seven Days of Local Delights at the Red Hills Small Farm Alliance website: https://www.redhillsfarmalliance.com/seven-days. If you are not in the Tallahassee area, check with your local extension office to see what gardening events they may have available and how you can support your local food community and farmers in your area.

What in the world is happening to the tomato in this photograph? Are those hostile parasitic plants taking over the tomato?
No, nothing so sinister. You are just seeing anxious new tomato plants sprouting from the seeds inside the tomato.
A naturally-occurring plant hormone normally prevents seed inside of fruit from sprouting too soon. But sometimes the piece of fruit is hanging around a bit longer than nature planned and the hormone that prevents the seed sprouting is depleted. So, the seeds start to sprout and look like squiggly white worms inside the tomato. With enough time, they pop through the skin and emerge as little tomato plants.

This phenomenon also commonly happens in pepper, citrus, apple, jackfruit, avocado and pear.
Yes, you can separate the little plants and plant them on their own if you would like.

Shrubs can serve many purposes in a landscape and have been used in both mass plantings and as accent features. They can include plants that offer colorful blooms, food for pollinators, and screens for less than favorable views.
We tend to think that shrubs will be permanent feature in our landscapes, because many are hardy and adapted to our climate. Like any other plant you may choose for your yard, shrubs may not live forever and there are a wide variety of reasons a shrub may need replacement after years of solid performance.
Let’s use any example from my own yard of the Dwarf yaupon holly, Ilex vomitoria ‘Nana.’ Back in 2001, I planted three hollies, spaced with plenty of room to grow, in a border area of my landscape. The plants grew well forming mounds about 3.5 feet high and 4 feet wide. Since the ‘Nana’ holly is a naturally mounding shrub, it did not require pruning and once established, rainfall supplied needed water.

Over the past year, several areas of branch dieback have developed in all plants. After finally deciding that the dieback was unattractive enough to warrant plant removal, I began cutting the plants back. I discovered dead interior branches, girdling roots, and some internal stem discoloration. In other words, there are many factors that have led to poor plant performance. Another issue is a large Loropetalum hedge (planted by my neighbor) that shades one side of the plant.

What could I have done to help these plants stay healthier for many more years? I could have prepared the rootball better for planting by shaving off the edges or supplied a little fertilizer on occasion in my sandy soil. These practices may have extended the life of the plants for several more years, but they may not have made a difference. Sometimes shrubs decline and die. I am accepting that not everything performs at an outstanding level in our climate. Also, there is an end point for some of my favorite plants in the yard. Some may outlive me while others thrive for a few years or a decade or so.
The bright side of loss of my Yaupon hollies is that I get to plan for a feature for the new year. Maybe something for pollinators and birds to last the next 17 years.

Fatsia japonica, common name Japanese aralia, provides tropical texture to your landscape. That coarse texture is attributed to its large (nearly a foot wide) leaves that are deeply lobed (maple leaf shaped). This shade-loving plant performs well in moist (not soggy) locations. Upright stems originate near ground level usually near the base of older stems. The stems grow to about eight feet tall before bending toward the ground under their own weight.
Even though the foliage of this species is enough to make you want it in your own garden, you will absolutely fall in love with its blooms. Upright clusters of showy, creamy white flowers begin to appear in fall. These little snowballs provide wonderful color to your garden. The shiny, black fruits appear in winter and are prominent for several weeks. The fruit are know to attract birds to the landscape.

Fatsia japonica thrives in the shade in slightly acidic, nutrient-rich, moist soil. Older stems become leggy and can be cut back to encourage branching. In the right place, Fatsia japonica is low-maintenance and not typically bothered by pests. It is also known to perform well in coastal landscapes. It fits well in entryways, in containers, or in mass plantings spaced three feet apart.
