Palms in North Florida suffered serious damage as a result of freezing weather in December 2022. As spring approaches, we will be looking to see if the palms will recover. Learn what to do now and what to expect from your palms with UF IFAS Extension Escambia County.
Temperatures in December 2022 were very damaging to many citrus in North Florida. It is necessary to give plants plenty of time into spring and summer to see if they will regrow and where that growth will occur. Learn how to care for your citrus that is suffering from cold temperature damage with Beth Bolles, UF IFAS Extension Escambia County.
Several times each month I am diagnosing shrub and tree problems in Escambia County that are related to the same issue, improper planting. Symptoms of this problem can be slow growth, leaf browning, and dieback. Sometimes under stressful weather conditions like drought, plants completely die.
This is a difficult sight for homeowners who have invested time and money in a tree or shrub to enhance the landscape. In some cases, the planting issues can be fixed but there are other times when a new plant will need to be installed.
The good news for homeowners is that this is a completely preventable issue. The University of Florida has excellent publications with photos about installing and caring for trees and shrubs. My Panhandle colleagues and I have also shared numerous articles and videos on proper plant installation.
Care must be taken during installation to set your plant at the correct depth. Even if a landscaper or nursery is installing the plant for you, check their work. Make sure the rootball is cut or sliced, it is not set below grade, that any straps holding the rootball are cut after it is set, and proper backfilling occurs without soil over the top of the rootball.
You don’t want to find out later in the season or even year’s later that your plant declined just because of planting problems.
Tropical milkweed, Asclepias curassavica, has become a commonly grown monarch host plant in many gardens. It grows very well in our climate and survives into Fall and Winter during many years. This long life of Tropical milkweed is not necessarily a good trait for the monarch butterfly. In the Fall, monarchs are in migration mode and need to move out of our area to overwinter in warmer climates. Live host plants that are found during migration may interrupt the process. An additional problem is that Tropical milkweed may be host to a disease caused by a parasite that can impact the health of Monarch butterflies. The best tip to help our migrating Monarch butterflies, is to cut back your Tropical milkweed to the ground each Fall or better yet, grow native milkweeds that usually die back on their own.
We grow many types of hydrangeas in North Florida. In order to prune your hydrangeas at the correct time of year, you need to identify which types you have in your garden.
Bigleaf hydrangea (Hydrangea macrophylla)
Bigleaf hydrangea (Hydrangea macrophylla) comes in mophead and lacecap flower forms. They bloom on old wood, so prune in summer after blooming is finished. Repeat bloomers, such as ‘Endless Summer’ bloom on both old wood from the previous year and on the current season’s wood. You can prune after the first bloom and still get a bloom later in the season.
Oakleaf hydrangea (Hydrangea quercifolia)
A native hydrangea that blooms on old wood, so prune after flowering. This type requires little pruning, only
to maintain size and shape.
Panicle hydrangea (Hydrangea paniculata)
These shrubs bloom on new wood, so prune in winter or early spring before new growth emerges. ‘Limelight’ and ‘Pee Gee’, are examples of this type. Plants only require pruning to shape or thin out the shrub.
Here are some additional pruning tips for your hydrangeas.
For all types, check for winter-damaged wood in early spring. Remove all dead branches before buds start to open.
Some plants need rejuvenation pruning. Old wood may die back or be less productive, so in early spring remove very old stems at the base. This stimulates new growth.
Deadheading flowers (cutting off spent blooms at a set of leaves) can happen as needed.
