Crape myrtles are all around good tree selections for the landscape. When left in their more natural form with just a little selective pruning, crape myrtles can provide shade during our hot summer days. Learn the many qualities of the crape myrtle with UF IFAS Extension Escambia County.
With the traditional planting date of Good Friday behind us, the home tomato gardening season in the Panhandle is in full swing. While tomatoes are the most persnickety veggie we grow, there are several practices you can adopt to help you succeed: selecting an adapted variety; regularly scouting for insects and disease; and watering and fertilizing appropriately. However, the most overlooked practice for success gardeners can adopt is proper pruning.

Correct pruning does a couple of positive things for tomatoes. First, it reduces the incidence of disease by preventing leaf contact with the soil, opening the interior of the plant, and allowing better airflow. This is important as many plant pathogens reside in the soil and only need a splash of water to travel onto plant leaves. Also, densely foliaged plants trap warm, moist air in their canopies, creating a perfect environment for disease to flourish. Letting the plant canopy “breathe” through pruning prevents that negative environment from forming! Second, correct pruning of “suckers” (extra growth points that can develop into shoots) helps tomato plants develop optimum yield and fruit quality. By removing suckers, more water, nutrients, airflow, and light are directed to the main stems, where the majority of tomato fruit production occurs. Failing to remove suckers (especially on indeterminate varieties) can result in reduced yields, increased disease, and generally messy plants!
With the reasons for pruning tomatoes established, the next step is learning exactly what to prune and how to do it in a sanitary matter.

While tomatoes are indeed a difficult vegetable to grow, learning to prune them correctly will greatly help to make this a successful season. If you just keep leaves off the ground, suckers pinched, and pruners cleaned, you’ll be well on your way to less disease, prettier plants, and more tomatoes to pick. For more information on growing tomatoes and any other horticultural topic, please contact your local UF/IFAS County Extension office. Happy Gardening!
Ornamental grasses are a great addition to the landscape. Most are usually easy to establish, need little water and fertilization, provide different textures, and are generally low maintenance. The one main maintenance activity that is necessary for most of our north Florida ornamental grasses is a good “haircut” in the spring.

Pruning grasses removes the spent flowers and seed heads, as well as all of the brown leaves, which provided the fall and winter interest that ornamental grasses bring to the landscape. These leaves also serve as a sort of natural wind-chime during the cold, windy days of our winters and may even provide cover and nesting material for wildlife. However, now it’s spring, and lush green growth is waiting to pop through that dead mix of leaves and stems. Pruning clears all that out, allowing for good air movement and a rejuvenation of the plant that can help minimize pests and disease.

To prune ornamental grasses, wait for after the last average frost date and grab some nice sharp shears. Next, just shear the clump about six inches above the soil line working from the outside towards the center with a slight angle, creating a sort of fade effect. For larger specimens you may need to adjust the cut a bit higher and may even want to use a hedge trimmer. Nice clean cuts are preferred.

One good pointer I saw online is to also bring along an old belt or a piece of rope to cinch up the dead material before pruning to easily collect the debris. I tend to use a cut and swipe motion that pushes the large material to one side of the plant, and I follow up with a metal garden rake to pull out more of the old, coarser material.
Within no time, new growth will flush out from the mound and often surprise you with how quick it can grow. This proves just how dynamic ornamental grasses can be in the landscape, showcasing lush green growth during one season and providing stark, whimsical interest during another.

Flax lily is a popular perennial that adds interest to garden borders or when planted in mass. Plants can be affected by cold temperatures so a little maintenance as temperatures warm is often necessary. UF IFAS Escambia County Extension shares late winter care of flax lily In the Garden.
The term “ornamental grass” is a catch-all phrase used to describe grasses and “grass-like” plants. Individual species are adapted to a wide variety of landscape sites (i.e., wet or dry, sun or shade, hot or cold climates, and varied salt tolerance). Growth habits range from low ground covers to intermediate shrub-like plants to very tall hedge-like plants. Ornamental grasses are very dynamic; the size, shape, texture, and color of grass changes with every season.
Deciduous Ornamental Grass
Grasses with foliage that dies in the winter and remains dormant until the weather warms in the spring are considered deciduous. The winter character of deciduous ornamental grasses adds tremendous interest to the winter garden when contrasted with evergreen plants or structures such as walls or fences. The dried foliage of deciduous grasses creates sound as it expands and contracts in response to changes in temperature or moisture, while interaction with wind creates movement in the garden. For these reasons, pruning of the dead foliage and inflorescences is not recommended at the time of the first frost.
Pruning of ornamental grasses should be done in late winter or early spring, just prior to new shoot growth. In Northwest Florida, gardeners should target the end of February to prune ornamental grasses. For deciduous grasses, such as Japanese silver grass (Miscanthus sinensis), the old foliage may be completely removed within inches of the soil. Be cautious to not remove the growth point by leaving the grass clump at least 4 inches high. For evergreen grasses, such as muhly grass (Muhlenbergia capillaris), the ragged leaves can be removed to neaten the appearance of the plant without shortening all the way to the ground. So, depending on the damaged portions, the remaining grass clump can be 6-18 inches high after pruning. Grasses recover quickly from a heavier pruning. Within a few months the plant will have completely regrown. If desired, old flower stalks and seed heads may be removed any time they no longer have a neat appearance.
