Video: Tree Planting Basics
Our winter season is a good time to install many trees and shrubs. Here is a basic review of a few planting practices to make sure that your new plants get off to the good start.
Landscape Installation Planning and Preparation
It is mid-summer with temperatures outside in the 90’s plus, so you may wonder why article on landscape installation considerations during this time of year. It simply is an excellent time for planning and preparing for fall and winter site prep and planting well before it arrives, reducing a time crunch when it is time to plant.
Think healthy plants for our Northwest Florida settings, proper preparation of the site before planting, and many other points to be successful with establishing a landscape that will be enjoyed by all. This article will address the use of woody ornamental plants, but many things discussed can be applied to perennials and annuals as well.
Before starting, make sure to do your homework not only on the plants and placement in the landscape, but any county, city, or homeowner association requirements to work within. Many neighborhoods have review committees for these approvals. This commitment by you when purchasing property and a home can be a part of the closing papers during the purchase. If you are required to submit for an approval before work can begin you might want to consider consulting with a professional landscape company to assist in this process. Always ask for references and sites you can visit before securing services.
Site preparation can be a afterthought, with limited funding focused on this critical area, but properly addressing it leads to healthy, vigorous plant establishment and future growth. Understanding the site from soil type and drainage, size of area, sunlight, water availability, plus needs of prospective plants goes a long way to being successful. If there are plants already established on site that may be worth keeping, be sure to include them in the consideration. Determining soil drainage, moisture retention that would be available to plants, soil pH and structure will also go a long way to determining the type of plants that work best for the site. If, for example, your site does not drain well and holds higher levels of water in the root zone area (top 12″ of soil), consider plants that grow well in wet settings. The next steps are determining soil pH and nutrient needs for general landscape plant growth performance. Many plants thrive in slightly acidic soil (pH 6.0 to 7.0 range) while others grow best in moderately acidic settings (pH 5.0 to 6.0 range). Contact your local UF IFAS Extension office in your county for additional information.
The landscape site brings other considerations for plants to flourish, involving space and light. Space should be considered both above and below ground. With the above ground area, is there room for the limbs to expand in width and height? If pruning is required to manage the size, considering another plant may be a viable option. Next is the root growth and expansion opportunity for the plant. If the root area is limited in space, other options may need to be considered to mitigate compacted soils or pavement areas. Adding raised beds for better soil drainage and increased root growth room may be an option. Be sure to know your soil type and use a similar soil with characteristic that match the existing soil. If you do not, there can be incompatibility that leads to a hard pan layer between the soils reducing potential root zone establishment.
The desire to develop and establish an enjoyable landscape for all to appreciate can be a challenge, but a positive one. As a reminder, call and go visit with your local UF IFAS Extension office, there is great research information available for the asking. Enjoy your gardening experience.
Planting Depth Problems Continue
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.
More Gardening Tips for February & March
Are you “chomping at the bit” to get started gardening this year, but not sure what you can do at this point? Well, good news, there’s plenty of things that can be done whether landscaping or vegetable gardening is your passion.

Temperatures can drop significantly in the Panhandle this month, and with short notice. If you want to enhance your flower beds, be sure to use annual bedding plants that can withstand the chill. Dianthus, pansy, viola and dusty miller are some good suggestions to plant. It’s a good time to plant bulbs too. Dahlias, crinum and agapanthus are good choices this time of year. Be sure to provide adequate mulch and water during this cold weather month. There are plenty of trees and shrubs that are beginning to bloom this time of year also. If you’re like me, your allergies will tell you this too. Red maple and star magnolia, just to name a couple, will soon be in bloom.
As for vegetable gardening, the potato is a good choice for Florida gardens. As Americans, we consume approximately 125 pounds per person a year. Potato farming is done commercially in Florida, but mostly with “new” potatoes. These are the small, rounded immature potatoes that have a thin skin and are perfect for low country boils.
It’s February, so it’s Irish potato planting season. The planting season for this cultivar for the Panhandle is from February 1st to mid-March. Sweet potatoes can be planted beginning in late March through June. A hundred pounds of seed potatoes should yield approximately ten bushels. Buy healthy certified seed potatoes from a garden center. Avoid using table stock potatoes. Often, table stock will not sprout successfully. Store bought potatoes are often treated with sprout inhibitors too. This treatment can cause development issues if used as seed potatoes.
Raised beds, at least 6”, are the best way to grow potatoes. Be sure to fertilize the bed soil mixture and fertilize again down furrows when planting. Irish potatoes require copious amounts of fertilizer. For fertilizer, use a general, complete formulation like 10-10-10. Before planting, be sure to dust the seed potatoes with a fungicide to reduce the chance of decay. Plant seed potatoes 3” in depth, at 12” apart and allow for 36” row spacing.
Please take these gardening tips into consideration this month and the next. Spring is just around the corner. Happy gardening! For more information please contact your local county extension office.

Winter Planting and Spring Preparing

It is freezing cold this week and hard to believe that we are already talking about “What to Plant” and “What to Do” to get started early. In North Florida there are cool-season annuals that can be planted now. The list includes pansies, violas, petunias, and snapdragons. As we are coming to the end of January it is time to plant crinum, agapanthus and gloriosa lily bulbs. Make sure to mulch these areas after planting to protect them from the cold temperatures. This is also the month to plant camellias, which these come in many colors and forms that your local nurseries will carry this time of year. If you haven’t planted all your cool season crops there is still time to do that now such as broccoli, kale, carrots, and lettuce. Irish potatoes can be planted now as well.
Now you might be asking “What can I do?”. January is a great time to prune non-spring flowering shrubs and trees to improve their form. This is a good time to plant deciduous fruit trees, this will give their roots time to develop before the warmer spring temperatures. Since existing trees are dormant, it is a good time to prune and fertilize them. When the temperatures are near freezing many of the tender plants will need to be covered to minimize damage. It’s a good time to plant a tree. Hurricane-resistant trees include live oaks, bald cypress, cabbage palms, and southern magnolias. It’s time to remove those dead spent seed pods on your crape myrtles and removing any crossing branches and twiggy growth will improve the appearance and the form of the plant.

As we go into February it will soon be time to apply a preemergence weed killer to your lawns to prevent warm-season weeds. Temperatures must rise to 65°F for 4 to 5 consecutive days before you do a preemergence application and make sure you are not using a weed and feed fertilizer. Citrus and other fruit trees can be fertilized at this time. The amount and frequency will depend on the age and type of fruit tree you are growing. Avoid pruning Citrus until spring to avoid any injury since cold temperatures are still possible. It is time to prune those roses this month to remove damaged canes and improve the overall form. After the pruning is complete you can fertilize and apply a fresh layer of mulch. They should begin blooming within 8 to 9 weeks after being pruned.
Dianthus, pansies, violas, and dusty millers are annuals that can take a chill and should be planted in February. You can continue to plant crinum and agapanthus this month and add on amaryllis and rain lily bulbs as well. If it has been dry make sure to provide plenty of water for the bulbs to establish and continue to protect them from the cold by adding mulch. Trees and shrubs will begin to bloom this month including red maples and star magnolias. Continue planting potatoes throughout the month and towards the end of February warm-season crops like tomatoes and pepper can be planted but be prepared to protect them from any late frosts.
