After a few years, many perennial plants have grown so large that they need to be divided in order to be revived. Overcrowding causes them to bear fewer flowers and, sometimes, to die in the center. Fall is a good time to divide perennials that bloom in spring and summer and are now done blooming for the year. This is a great way also to expand your perennial beds or share some of your perennial favorites with friends and neighbors.

Some examples of perennials to divide in the fall are:
- Stokes’ aster, Stokesia laevis
- Daylily, Hemerocallis spp.
- Black-eyed Susan, Rudbeckia hirta
- Yarrow, Achillea millefolium
- Crocosmia, Crocosmia spp.
- Flax lily, Dianella tasmanica ‘Variegata’
- Liriope, Liriope muscari
- Cast iron plant, Aspidistra elatior
The first step is to dig out the entire clump. If there is enough clearance in the garden bed, start digging about six inches out from the plant and dig straight down beyond the root zone. It’s best to get as much of the roots as possible to lessen the shock of transplanting. If the clump is too heavy to remove, make your divisions right there with a sharp blade, trowel or shovel. Often, you can just pull them apart with your hands.
Before replanting the divisions, consider adding some nutritious compost to those areas of your garden bed to ensure healthy plants. Be sure to replant as soon as feasible to protect the roots from drying out. After replanting, water the transplanted divisions well and mulch appropriately.

When you know that your lawn needs an application of fertilizer, herbicide, insecticide or fungicide, the question becomes how much to buy and put down. For these products, success stems from applying the right amount, not too much or too little. The label on those products always tells the consumer how many square feet of lawn can be treated, but how do you figure that out?
You could always do it the old-fashioned way with measuring tape and a calculator, estimating the angles and the areas of those curvy, irregular flower beds. This method takes a bit of time and you will still wonder about the accuracy of your final numbers.
Here’s an easier, and more accurate way to do it!
Sod Solutions, Inc. offers an online tool that is easy to use and very accurate. Enter your address and GPS locates the aerial view of your property. Create an overlay by plotting points and the square footage is automatically calculated. The instructions under ‘How to Use the Calculator’ are very clear and makes this tool so easy and convenient to use.

July always brings the blessing of abundant figs on my trees. A new crop waits to be picked and enjoyed every day for nearly a month. The tender sweet fruit can be enjoyed fresh, prepared into jams or used in a myriad of recipes.

The fig (Ficus carica) is native to Asia Minor and the Mediterranean regions of the world and has been cultivated for an estimated 7,000 years. Spanish explorers brought the fig with them to Florida in 1575 and it has had a presence here ever since. Since the fig is adapted to a dry climate in its native regions, the humidity it encountered in Florida can cause fruit to split; but new cultivars have been developed to minimize this problem.
Fig trees usually grow to a maximum of 25 feet and have large bright green leaves that fall in the autumn. Fruit develops from June to August, depending on the chosen cultivar.

Choose a spot for planting a fig tree that receives full sun and good drainage. Once established, figs are drought tolerant and only need supplemental irrigation if we have an extended drought. No structural pruning is required but you can prune to keep the tree from growing so tall that you cannot pick the delicious fruit. Be sure to do your pruning just after the fruit is gone as the fruit develops on the terminal ends of the branches from last year’s growth.
Many figs grow and fruit sufficiently without applied fertilizer, however, a light fertilization with a 10-10-10 with micronutrients can be helpful for small trees getting established and those with reduced fruiting. Young trees can benefit from a ½ pound three to five times from February to August while large trees could use up to 4 pounds per application on the same schedule.
There are a few pests that do damage figs; the most common, though, are the birds and squirrels that get the fruit before you do. Seldom do figs need to be sprayed when grown in the home garden.

Butterflies are not only beautiful to look at in your landscape; they serve as important pollinators and indicators of the health of our environment. Attracting them to your garden and incorporating some features to get them to stay and make it their home involves a little planning ahead of time for optimum results.

Choose a location that provides some protection from wind. Trees and shrubs that provide wind protection also serve as a safe harbor from rain and predators. The garden should be mostly sunny with some part sun areas. Ensure that any new plantings have access to a convenient irrigation source so they can be successfully established and maintained in good health.
Now you’ll need to choose the plants. Adults feed on the nectar of many flowering trees, shrubs, perennials, and annuals and, fortunately, there are usually many choices that will meet your site requirements and your taste preferences. In order to keep the butterflies in your garden, certain plants need to be available to serve as host plants for their young. Determine which species of butterfly is common in your area and that you want to attract. Most species have very few plants on which the caterpillars can feed so those host plants need to be chosen wisely. Determine whether any of the plants you already have are host plants and they can be integrated into your butterfly garden. For example, cassia is a host plant for the Cloudless Sulphur and citrus is a host plant for the Giant Swallowtail.
In choosing your nectar plants, select those that are native or Florida-Friendly as they are lower maintenance, giving you less trouble in the long run. Choose plants that have flowers in a variety of color, size, and shape. Different butterflies like to feed at different elevations, so choose trees, shrubs, perennials, and annuals of varying heights. In order to have nectar available throughout the time when the butterflies occur, include plants that bloom at different times of the year. And include some plants that bloom from spring to late fall, like pentas or moss verbena.
Larger plants should be placed in the background with smaller plants layered in the foreground. When you plant smaller annuals and perennials, place them in masses to better attract the butterflies. Consider placing host plants in an area that is in close proximity to the nectar plants, but in an area of your garden that is not a focal point. Host plants can get quite ragged looking from hungry caterpillars!
Good maintenance practices will enhance the health of your garden. Regular fertilization and irrigation if needed will help keep your plants in bloom and healthy; healthy plants are less susceptible to disease and pests. Avoid pesticides as they may harm the very creatures you are trying to attract. Never use Bt or systemic pesticide. If you must, target a pest with lower risk oils or soaps and then only treat the affected plants. Lastly, be aware of beneficial insects that will help you achieve satisfactory control of a pest.
Now that your plants are placed there are several things to do to make your butterfly garden complete. Add a spot where water can puddle on the ground for the adult butterflies to drink. They require minerals from the soil that get dissolved in the water. Also add a rock or log in a sunny spot where butterflies can rest and sun themselves. And consider placing a comfortable place for you to sit and enjoy the beauty of your garden and its inhabitants!

Many of us are working during the day and are not enjoying our gardens during the daytime. And maybe it is just too warm in the summer to be outside during the heat of the day. That leaves us to enjoy our gardens later in the day when the sun fades and evening approaches.
As the sunlight diminishes, the bright colors fade slowly to a black, gray and white world. The first colors to fade are the blues, purples and reds. Pastel pinks, yellows, oranges, grays and blues remain more visible for a longer time and take on a luminescent quality in the pale light. White blossoms now have their time to shine as they stand out against the darker hues of foliage and flowers.

If you find that your time in the garden is late in the day and into the evening, consider planning for that in your plant selections.
Here are some suggestions when planning your twilight garden:
- Add some late-afternoon and night-blooming plants such as four o’clocks, moonflower and night-blooming cereus
- Plants with silvery gray or white foliage glimmer in the moonlight. Consider white caladium, lamb’s-ears, silvery agaves, dusty miller and licorice plant among others. The white in variegated leaves of plants such as pentas, hosta, ginger and dogwood will stand out when dark green leaves have faded into the darkness.
- The tranquil sounds of a fountain will enhance end of the day relaxation.
- And, of course, add plants with white or pastel-colored flowers. The effect will be enhanced when luminous white blossoms are at different levels; for instance white spider lilies near the ground, white roses at eye level and white sparkleberry high above.
