How can an animal that does such much to help rid your lawn of pests be so hated by most homeowners? Such is the life of the mole.
The beneficial mammal is a soil dweller that tunnels through the soil, increasing aeration as it searches out a meal of beetle grubs, mole crickets, and slugs. Moles prefer loose soil and can tunnel more than 15 feet an hour. Moist soil brings the food source closer to the surface which in turn bring moles up to expose raised tunnels to homeowners. These tunnels are mostly cosmetic and show up easily in mulched areas and lawns with heavier weed populations. Most homeowners with a healthy, thicker lawn will rarely notice mole activity unless they encounter loose areas as they walk over the turf. These can easily be pressed back down with your foot.

There are management techniques for moles which include traps and ridding the lawn of the food source. The best practices are to manage the turf through proper mowing, watering, and fertilizing to create a uniform, healthy cover. For the most part, mole management is not even required. Consider the benefits of the moles as predators and allow them to be a natural part of the landscape environment. For more information on moles read the University of Florida IFAS Extension publication.

Landscapes will soon be transitioning from the dormant phase to actively growing and one of the most beneficial insects of all will be back in action. As soon as flowers open, bees will be visiting to gather pollen and nectar.
This year be a little more observant in the landscape and at your local nursery so that you protect bees during your yard activities. Several insecticides will have new labels that indicate a toxicity to bees and restrictions about applications to blooming plants. Since many landscapes have a wide variety of blooming plants, be very careful not to inadvertently spray when bees are visiting open flowers. Bees are not only killed by a direct spray of certain insecticides, but may carry residual pesticides back to the colony in pollen and nectar.
Since bees and other pollinators are so vital to our food production system, all people who work in landscapes or enjoy gardening as a hobby, need to be a part of bee protection. Read labels, only spray when absolutely necessary, and learn that a little cosmetic damage is worth it in order to protect pollinators.
Some selections of hollies are one of the first landscape shrubs visited by bees in the winter. Learn about the other plants in your yard that are visited by bees so you are better able to protect them.

Looking for a new shrub or small tree this year? Interested in one that is low maintenance and offers beautiful green color? Why not try a holly.
Hollies can be found in landscapes throughout North Florida. Many times these plants are used in foundation plantings around homes. They can help make the transition from the hard lines of a home to other parts of the yard. In other landscapes, hollies make an excellent screen, dividing property or blocking a view.
Because hollies are commonplace, they may be overlooked by homeowners who want to add an attractive new plant to the landscape. Hollies have many uses and there are new selections entering the market worth considering.
In general hollies will not need a great amount of maintenance. Once established most species will require only occasional water, fertilizer, and pruning. Many hollies have even grown well under neglected conditions. If you are one that keeps holly plants pruned as hedges, you will need to watch for the scale insect and spray plants with a horticultural oil every year.
When selecting a holly plant, it is good to know a little about the area where you want to place the plant. Hollies vary in size and ability to tolerate wet soil, so it is important to match a species with your specific site. Also consider holly leaf shapes when using the plants in areas where people walk. Some holly leaves are very stiff and sharp and could injury visitors to you home or be a nuisance when you are working in the yard.
If you are interested in the added beauty of holly berries during the year, remember to select a female plant.

Tree form hollies that you may select include the American holly (Ilex opaca), Savannah holly (Ilex x attenuata ‘Savannah’), and the Burford holly (Ilex cornuta ‘Burfordii’). All three plants will need well-drained soil. The American and Savannah holly will both reach heights between 20 and 40 feet and have a pyramidal growth form. The Savannah holly leaves will be a lighter green color than the leaves of other holly species. Burford holly has thick dark green leaves and grows about 12-15 feet in height over time.

If you have a wet site, consider the Dahoon holly which can be a specimen plant or used as a screen. This plant will develop attractive grayish bark and grow about 20 feet in height with more of a spread than the previously mentioned hollies.
There are medium-sized hollies that make excellent specimen plants about 12 feet in height. ‘Festive’ holly has dark green foliage and forms dense growth in a pyramidal form. The ‘Robin’ holly has a similar growth form but displays beautiful reddish new growth. Both of these plants will need well-drained soil and full sun or partial shade.
For those areas that require smaller evergreen plants, consider a ‘Bordeaux’ yaupon holly. These plants will grow about 4 feet in height and spread and form a dense growth of stiff stems with small leathery leaves. Since these plants keep a naturally round form it is not necessary to shear them. Both hollies will tolerate a wide range of soil conditions and require little maintenance once established.

Trees and shrubs often serve a distinct purpose in landscapes, other than to provide color. They are planted to provide shade, screen a view or noise, or to soften the hardscapes of the home.
With a little planning, we can have both beauty and function from trees and shrubs. Add a few trees and shrubs that have color in different seasons and your landscape will always be interesting.
The added benefit of growing trees and shrubs is that they are low maintenance. Once the plants are established in the landscape, they will require very little water and only an occasional application of a slow release fertilizer. A good layer of an organic mulch around the plants will help conserve moisture, prevent weeds, and keep root temperatures regulated during our temperature extremes. You may have to do a little pruning every year to remove any diseased, damaged, or severely crossing branches.
Here is a list of plants to give you garden interest throughout all seasons:
Winter color
- Taiwan cherry (Prunus campanulata) is an underutilized ornamental cherry for the coastal south. Clusters of dark pink flowers cover the plant which grows about 20 feet.
Taiwan cherry
- Camellia japonica is widely used in landscapes, but still an excellent choice for winter color. Careful selection of types will provide a garden with color from November through April.
- Red maple (Acer rubrum) will provide color in both the late winter and fall. Flowers are brilliant red in late winter and leaves begin turning red in late October.
- Other choices include Oakleaf hydrangea, Florida anise, Red buckeye, and Japanese magnolia
Spring
- Fringe tree (Chionanthus virginicus) can be in shrub or tree form and range in height from 10 – 20 feet. Forms white clusters of showy fringe-like flowers in late winter and early spring before the leaves emerge.
Fringe tree
- Chinese fringe (Lorepetalum chinesis ‘Rubrum’) is a very popular shrub. Pink blooms are heaviest in the spring. The plants can get up to 12 feet in height so plant it were it will not obstruct a view.
- Virginia sweetspire (Itea virginica) forms clusters of white flowers. Plants offer purplish foliage in the fall.
- Other choices include Banana shrub, native azaleas, Indian hawthorn, and Deutizia,
Summer
- Chaste tree (Vitex agnus castus) is a large shrub with fragrant leaves and spikes of purple flowers. Tolerates drought and develops interesting shape.
Chaste tree
- Loblolly bay (Gordonia lasianthus) is an evergreen tree that grows to 25-35 ft in height. Large white flowers with yellow stamens resemble camellia blooms.
- Abelia spp has white flowers that appear over the entire plant. It is attractive to butterflies .
- Other choices include Crape myrtle, Althea, Confederate rose, and Oleander
Fall
- Bald cypress (Taxodium distichum) will become a large tree over time. In the fall the feathery leaves will turn orange-brown. Good tree for both wet and dry areas.
- Beautyberry (Callicarpa americana) a native that forms clusters of purple berries that line the stem. Leaves turn yellow and provide fall interest as well.
- Cassia bicapsularis can reach 8-12 ft in height and will have bright yellow flowers that form in October and persist until a freeze.

For best root development, thin carrots to 2-3 inches between each plant.
Many common cool season vegetable garden plants are started in raised beds by direct planting of seeds. It is important to follow the guidelines in the ‘Monthly Vegetable Planting Guide’ (Page 6) for plant spacing and seed depth. It is possible to thin out seedlings that are growing too close, but seeds that are planted at the incorrect depth may not germinate.
Vegetable seedlings will need to be thinned out after germination to allow for adequate space for leaf or root development. Crowded vegetables will compete with each other for water, nutrients, and sunlight and never produce quality plants.
Here are some tips for thinning seedlings:
- When plants are about 1 to 2 inches tall or have two sets of ‘true leaves’, it is time to thin out any crowded plants.
- Look up the proper spacing between plants and thin out appropriately.
- Pull out seedlings with fingers or forceps to make space or use small
scissors to cut off seedlings at the ground level.
- It will initially look like there is lots of room between seedlings but realize plants will grow quickly to utilize all available space.
