I recently had the pleasure of visiting Bok Tower Gardens in Lake Wales, Florida and experienced one of their newest additions, a children’s garden. As much a playground as a place for growing plants, it was full of whimsical energy and invitations to explore. The entire area encouraged children to reach beyond their comfort zones and engage with nature, including an outdoor art space, a climbing area made of lean-to logs, and a covered sand “box” shaped like a snake.
In recent years, sociologists, educators, and health experts have bemoaned the loss of free outdoor play in the lives of children. Multiple factors, including the rise in electronic entertainment, more organized, practice-heavy youth sports, fears of crime/abduction or just lack of safe access to ride bikes or walk, have contributed to a drop in the frequency and length of time that kids spend outdoors playing on their own. Many readers can probably relate to my childhood. We would take off on bikes in the mornings during summer and not come back until we got hungry. We didn’t have cell phones or GPS, and we knew all of our neighbors so we had a place to go if we had a rare emergency. The results of fewer child-led outdoor explorations include increases in childhood obesity, fear of the outdoors, difficulty with balance, agility, and managing excess energy.

One way to encourage kids to get outside and explore is to plant something in your yard, school, or nearby park that can serve double-duty as a window to explore. Landscaping with young people in mind should include a variety of plants with interesting heights and textures, fruit-bearing shrubs or trees to engage the sense of taste, and lots of color. Logs to sit and climb on are perfect for developing balance and learning to take calculated risks. In addition, it is important to engage kids in the design and planting of the garden or landscape–if they have a hand in developing the area, they’ll be more invested in its success. In fact, research has consistently shown that children who help care for school gardens are more willing to try the food they’ve helped to grow. Beyond expanding a healthy palate, participation in school gardens can increase “soft” skills, such as the ability to work effectively in a team, better communication, and an increased appreciation for nature. Many kids also do better in science and gain a deeper understanding of proper nutrition after working with gardens.
If you are not a gardener or landscaper but interested in taking children outdoors where they can learn and become more comfortable, the US Forest Service has taken the research related to “nature-deficit disorder” so seriously that multiple “Children’s Forests” have been developed. While there are still very few in the southeastern US, there are dozens around the country. The stated goals for a Children’s Forest are: 1) Connect kids, families, and adults to healthy outdoor activities across all landscapes. 2) Create new education and career opportunities. 3) Foster an understanding of how our changing environment affects the world and how people can work together to embrace these changes. 4) Provide professional development opportunities for educators, with emphasis on conservation and the natural world. Local state and national parks often provide excellent programs for families as well, such as the National Park System’s Junior Ranger Program.
The landscaping at this coffee shop uses color, log seating/climbing, and a variety of interesting plants to attract children to engage with the outdoors.
A program in Gainesville called “Kids in the Woods” has recognized the lack of youth engagement in the outdoors and created field trips and curriculum for students designed to help make sure they are comfortable in the great outdoors. No matter how you engage the youth in your life with nature, it is important that they get outside, get dirty, and go beyond their comfort zone. Their health, academic success, and even motor skills needed for sports and daily life will reap the benefits!

Edible landscaping has become a trend for many gardening enthusiasts. A combination of edible plants along with traditional ornamentals can create an artful presentation. There are some challenges when designing such a landscape, but in those challenges opportunities’ may be found. One of the most difficult challenges is making sure your garden or landscape is healthy and vibrant year-round since many edibles are short-lived annuals. These include plants such as eggplant, pepper, lettuce, artichoke and some annual herbs. There is a solution to this concern. First, know your edible plant’s propagation and maturity months. This way you can offset plantings to ensure color in your landscape. Another key measure is to mix some evergreen ornamentals in with short season edibles and long season edibles. Examples of long season edibles include berry shrubs, fruit trees and biennial or perennial herbs.

When designing your edible landscape, think about style and theme to help guide you through the process. A formal design has more straight edges and geometric shapes, whereas the more natural approach has meandering edges and irregular shapes. A color scheme in harmony is very important. Remember, an edible landscape should not just be a production food garden but a visual treat. The goal is not to grow a high yield garden, but only to produce supplemental edibles to make the endeavor worthwhile.
Dr. Gail Hansen, Associate Professor of Environmental Horticulture at the University of Florida, has developed twelve ideas when creating an edible landscape:
- Combine reliable, low-maintenance ornamental with edible plants. Use evergreen ornamentals to maintain enough green structure, so that potential cool season bare spots are not visual.
- Use support structures for an artistic effect and to assist in growth of some plants. Trellises, arbors and even tomato cages are some examples that can be used.
- Use containers in areas to keep the landscape more organized. Planters will also help in maintenance, as plants will be easier to reach and the soil will be easier to manage.
- Create some hard edges in your landscape. Raised beds, garden walls and borders will give defining lines to the landscape and promote a clean appearance.
- A pathway through the landscape will both provide an access to plants and give an inviting appeal. Brick pavers, gravel and mulch are good examples of pathway material.
- Remember color is key. Create a visually pleasing combination of plant color, form, texture and sizes.
- Always start by keeping it simple. So, start small and simple. Then, you can begin filling in the landscape.
- Look for one unique feature to create an added interest to you landscape and provide growth to plants. This could be a shade house for ferns and other hanging baskets or a hay bale, where lettuce, tomatoes or peppers could grow upon.
- Select appealing and easy to grow plants that you want to eat!
- Let plants reach maturity before taking them out of the landscape. For example, rainbow chard will grow larger, if allowed to continue to grow after seed has been produced.
- Use the Florida-Friendly Landscaping principle, “Right Plant, Right Place”, when adding edibles to your landscape. Match the growing needs with the most suitable location.
- Consider your location and layout for irrigation. All plants need some degree of water. An above ground drip irrigation system is usually the most flexible and adjustable irrigation method in regards to overall plant watering needs in a landscape.
Following Dr. Hansen’s ideas will help you create the edible landscape of your dreams. For more information on edible landscaping, please contact your local county extension office for more details.

Many of us are enjoying warmer temperatures this winter, but many deciduous fruit crops really need cold temperatures in order to break dormancy for the year. In areas that experience cold temperatures, plants have evolved the ability to survive by slowing growth and protecting sensitive tissues by going dormant. In order to break out of dormancy and begin growth again, plants experience an amount of chill hours (temps between 32 and 45 degrees F) that is suitable for specific areas. In our area, we normally range between 400 and 600 chills hours.
If we choose a fruit plant whose chill requirements match the amount of chill in our area, the plant will generally resume growth when it is safe for buds and tender tissues to develop. If we choose a plant with chill requirements higher than the amount our area receives, then the plant is not signaled to break dormancy and we end up with very sparse growth and no fruit.
So far in the winter of 2016-17, some areas have not received ‘normal’ amounts of chilling temperatures. Common fruit like apple, peach, some blueberries, and certain selections of blackberries may be affected by this by not breaking out of dormancy. This can impact your flower and fruit formation. For commercial growers, it can impact the amount of fruit available and even fruit prices at markets.
Since fruit trees are an investment of time and money, these are not plants that can be easily replanted to match chill hours with changing weather patterns. Perhaps planting fruit crops with a range of chill hours required might be beneficial Your future decisions to grow fruit trees may include crops that don’t rely as much on chill hours to be successful. For more information, please consult the Dooryard Fruit Varieties guide from UF / IFAS Extension.

Freshly harvested ginger rhizomes. Photo by Molly Jameson.
Fall is finally here and we are beginning to enjoy our first few bursts of cold air coming in from the northwest. For many, this inspires us to prepare dishes with all of our favorite seasonal spices – nutmeg, cinnamon, cloves, and ginger come to mind. While all of these spices can be grown, did you know that edible ginger, Zingiber officinale, is one of the easiest roots to grow in North Florida?
It is as simple as planting a piece of fresh ginger root, or rhizome, in the spring and keeping the root moist for a few weeks while they sprout. Ginger prefers soil rich with organic matter and partial shade. Therefore, it is often an excellent choice for yards with many trees, as is common among our many oaks and pines. It also has very few pests and can be largely ignored as it grows throughout the year.
During the warm seasons, you will enjoy this perennial’s dark green narrow leaf blades, and although not as showy as ornamental gingers, it will occasionally produce green oblong stalks with white and dark red fragrant flowers. When our cool nights return and the tops die back, it is the signal to dig up the roots, which will have multiplied, and take some in for eating and place some back in the ground for next year’s harvest.
After digging up the rhizomes, allow them to air dry in the shade. To make your ginger root last, place in a sealed bag, and store in your freezer, peeled or unpeeled. You can then take out pieces as you need them throughout the year, and it can easily be grated frozen.
So get ready to make ginger bread, gingersnaps, ginger muffins, ginger ale, ginger-based sauces, ginger spiced soup, and so much more, all with your fresh, spicy, pungent homegrown ginger root!

The daylily is a popular flowering perennial with East Asian origins which has adapted well to Florida landscapes. Plants are available in a wide variety of growth habits, flower shapes and colors, including yellow, orange, red, pink, purple, near-white and shades and combinations of all of these.
Flowering starts in March for early-season bloomers with late-season cultivars starting in mid-May. The typical bloom period is about four to seven weeks, although some varieties bloom even longer.
As their name accurately indicates, daylilies are members of the lily family, in the genus Hemerocallis. “Hemero” is Greek for “day” and “callis” for “beauty,” so the scientific name translates to beauty for a day.

For the adventurous eater, the flower buds and petals of daylilies are edible raw, boiled, stir-fried, steamed, stuffed, or battered and fried. Dried daylily petals, called “golden needles,” are used in numerous Chinese dishes.
Many of the modern varieties of daylilies available today have been developed from native Chinese species. Early settlers from Europe and Asia brought many of the original species with them to America in earlier centuries.
Daylilies grow best in full sun or filtered shade. The darker colored red and purple varieties flourish better in partial shade, while light colored yellows, pinks and pastels varieties need full sun to bring out their best colors. The filtered light level under pine trees is ideal for growing daylilies. Heavy shade should be avoided because it will cause thin, spindly growth and poor flowering.

The soil of daylily beds should be topped with three to four inches of organic matter, such as peat, compost, or well-rotted manure. The amended soil should be mixed or tilled, leveled and then moistened. The soil pH should be between 6.2 and 6.8, with 6.5 being optimal.
Daylilies survive dry conditions well because of their extensive root systems. However, the number and size of blooms, plant growth, and overall vigor can be adversely affected by prolonged drought.
Daylilies multiply fairly rapidly and plant division is an easy way to propagate them for new locations in the home landscape or to share with friends. Division is best done immediately after the flowering season. Dig the entire clump and shake or wash off the soil without damaging the roots. It is easy to see where the divisions can be made with smaller clumps being easily pulled free to establish a new planting.
The home gardener can expand and share the beauty of these perennials, only spending a little time to accomplish this feat.

Being a gardener in the panhandle has its advantages. We’re able to grow a tremendous variety of vegetables on a year-round basis. However, in this climate, plant diseases, insects and weeds can often thrive. Usually, chemical measures are applied to thwart these pests. Some panhandle gardeners are now searching for techniques regarding a more natural form of gardening, known as organic. With fall garden planting just ahead, this may be an option for conventional vegetable gardeners looking for a challenge.

So, what is organic gardening? Well, that really depends on who you ask. A broad definition is gardening without the use of synthesized fertilizers and industrial pesticides. Fair warning, “organic” does not translate into easier physical gardening methods. Laborious weeding and amending of soil are big parts of this gardening philosophy. This begs the question, why give up these proven industrial nutrient and pest control practices? Answer: organic gardening enthusiasts are extremely health conscious with the belief that vigorous outdoor activity coupled with food free of industrial chemicals will lead to better nutrition and health.
As stated earlier, the main difference between conventional and organic gardening is the methods used in fertilization and pest control. In either gardening style, be sure to select a garden plot with well-drained soil, as this is key for any vegetable crop. Soil preparation is the most important step in the process. To have a successful organic operation, the garden will require abundant quantities of organic material, usually in the form of animal manures and compost or mixed organic fertilizer. These materials will ensure water and nutrient holding capacity. Organic matter also supports microbiological activity in the soil. This contributes additional nutrients for plant uptake. Organic fertilizers and conditioners work very slowly. The vegetable garden soil will need to be mixed and prepped at least three weeks ahead of planting.
Effective organic pest management begins with observing the correct planting times, selection of the proper plant variety and water scheduling. Selecting vegetable varieties with pest resistant characteristics should be considered. Crop rotation is also a must. Members of the same crop family should not be planted repeatedly in the same organic garden soil. Over watering can be an issue. Avoid soils from becoming too wet and water only during daylight hours.
For weed management, using hand tools to physically removing weeds is the only control method. As for insect management, planting native plants in the immediate landscape of the organic garden will help draw in beneficial insects that will feast on garden insect pests. The use of horticultural oil or neem oil is useful. However, please read the product label. Some brands of oils are not necessarily “organic”. Nematodes, which are microscopic worms that attack plant roots, are less likely an issue in organic gardens. High levels of organic matter in soil causes an inhospitable environment for nematodes. Organic disease management unfortunately offers little to no controls. Sanitation, planting resistant varieties and crop rotation are the only defense mechanisms. Sanitation refers to avoiding the introduction of potential diseased transplants. Disinfecting gardens tools will also help. Hydrogen peroxide, chlorine and household bleach are disinfecting chemicals allowed in organic gardening settings as these chemicals are used in organic production systems for sanitation. Staking and mulching are also ways to keep plants from diseases by avoiding contact with each other and the soil.
Organic gardening can be a challenge to manage, but better health and nutrition could be the reward. Please take the article recommendations into consideration when deciding on whether to plant an organic garden. For more information, contact your local county extension office.
