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.
Get rid of any foliage that could encounter the soil, generally all leaves occurring on the lower 12-16″ of the plant. All kinds of nasty tomato destroying diseases, like Early Blight and Bacterial Leaf Spot, reside in the soil and are just waiting to be splashed onto your plants – don’t let that happen.
Determine how many primary shoots you want your plant to have. Leave enough lower suckers to achieve that number (generally just one, two, or three as more than 3 primary stems gets hard to manage), and prune or pinch out all the rest. To prevent stress from pruning, be diligent in removing suckers when they are still small, 2” or less.
Always clean and disinfect your pruners before making a cut on a tomato plant. This is best accomplished by rinsing the blades with warm soapy water, drying, and following with by a quick alcohol spray. A 10% bleach solution will also work, but if not thoroughly rinsed after, bleach can corrode pruner blades and other working parts. If you make cuts on a plant that appears diseased, repeat the sanitizing process before you begin pruning another plant as “dirty” pruners are an easy way to spread pathogens in the garden.

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.

There is an old saying that rings true in pretty much any situation – “You get what you pay for.” Gardening tools, especially pruners, are no exception. We’ve all been there, fumbling around with a pair of rusty, dull, cheap garden pruners that just barely get the job done. Unfortunately, they can also do considerable harm to the plants you’re trying to improve, as anything short of a nice, sharp, clean cut introduces the potential for insect/disease infestation and will produce a wound that takes much longer to heal, if it ever heals properly at all. You wouldn’t want your doctor to start hacking away at you with a dirty, second-rate scalpel. Don’t subject your plants to the same treatment! While I’m not advocating blowing hundreds or thousands of dollars outfitting your garden tool shed with top of the line everything, investing in a pair of quality bypass hand pruners will pay dividends many years into the future and make your gardening experience much more enjoyable!

Found in three designs, from old-fashioned anvil pruners that smush and smash their way to a cut, to ratcheting pruners that make short work of larger branches but tend to be cumbersome and complicated, to bypass pruners that produce clean cuts in a scissor-like manner, hand pruners accomplish many tasks in the landscape. From cutting small limbs, to harvesting vegetables, to deadheading annual flowers and everything in between, there isn’t a more frequently used, versatile tool. Therefore, it makes sense to buy a quality pair that will perform excellently, still be snipping long after your pruning days are over (if you take care of them), and that are comfortable enough you will enjoy using them. When shopping for your pair of “forever” pruners, there are a few things to look for.
Only use bypass style pruners. Your plants will appreciate it.
Look for heavy duty pruners with frames made from quality aluminum or stainless steel; they won’t rust and won’t easily bend or break.
Buy pruners with replaceable parts. This is especially key because springs eventually rust and gum up and blades break and will eventually lose their ability to hold an edge over time (though you can and should resharpen them).
There are two commonly found brands that fit all three above criteria, albeit at different price points. For a high quality “budget” blade, various models from Corona do an excellent job for the money ($20-30) and won’t hurt your feelings too badly if you happen to lose a pair. Should you decide to splurge a little, Felco makes sharp, indestructible pruners, in multiple models around $50 to fit all size hands. Felco has become the horticulture industry standard and you’d be hard pressed to find a nursery owner or landscaper that didn’t own a pair (or two).

Regardless of which brand you buy (and there are many more than the two above listed) a pair of well-made pruners, if taken care of, should last a lifetime and make your gardening experience much more enjoyable for you and your plants!
