Extension agents are frequently tasked with evaluation of unhealthy plants in the landscape. They diagnose all sorts of plant problems including those caused by disease infection, insect infiltration, or improper culture.
When evaluating trees, one problem that often comes to the surface is improper tree installation. Although poorly installed trees may survive for 10 or 15 years after planting, they rarely thrive and often experience a slow death.
Fall is an excellent time to plant a tree in Florida. A couple of weeks ago beautiful Nuttall Oak was planted at Bagdad Mill Site Park in Santa Rosa County, FL. Here are 11 easy steps to follow for proper tree installation:
Look around and up for wire, light poles, and buildings that may interfere with growth;
Dig a shallow planting hole as wide as possible;
Find the point where the top-most root emerges from the trunk;
Slide the tree carefully into the planting hole;
Position the point where the top-most root emerges from the trunk slightly above the landscape soil surface;
Straighten the tree in the hole;
Remove synthetic materials from around trunk and root ball;
Slice a shovel down in to the back fill;
Cover the exposed sides of the root ball with mulch and create water retention berm;
Stake the tree if necessary;
Come back to remove hardware after establishment.

On a recent family walk, I noticed something pretty obvious. One of our neighbors had a broken irrigation head. Luckily this is an easy fix, because a new rotor can just be screwed into place. But seeing the amount of water running into the street got me thinking about some additional ways to save water. Scroll down for some water saving tips based on the 9 Principles for Florida Friendly Landscaping.

4 Ways to Save Water
Pick the right plant for the right place. Turf is an excellent choice for catching runoff in the situation pictured above. However, it’s important to evaluate your yard based on the amount of sunlight received throughout the day. Once you’ve determined if you need sun loving, shade loving, or plants that can handle a little of both, you’ll want to check how well your soil drains. Some plants can handle wet conditions better than others. Use the FFL Plant Guide to help pick the plants for your space.
Irrigate based on plant requirements. Plants like to be watered thoroughly to the extent of their rootzones. For turf, we recommend irrigating deeply and infrequently early in the morning. This method encourages the roots to grow deep to reach the water needed. Most established trees and shrubs don’t need supplemental irrigation unless we’re going through an extended period of drought. Review the Summary of Turf and Landscape Irrigation Recommendations to help determine the amount of water your yard needs.
Calibrate the irrigation system. If you have an irrigation system, then you need to make sure it’s calibrated. To do this, you’ll first need to make sure your system doesn’t have any leaks or broken heads and redirect heads to water plants instead of the driveway, sidewalk, or road. Next, you’ll need to determine how long to run your system based on water output. The run time test is detailed on the UF/IFAS Calibrating Your Irrigation System webpage.
Use mulch around trees and shrubs. Mulch can help hold moisture and conserve water. It’s important to keep mulch to between 2 and 3 inches deep and at least 2 inches away from the base of trees and shrubs. There’s a lot more information on Choosing and Installing Mulches on the Gardening Solutions website.
Following these simple tips will ensure that you’re watering efficiently and effectively. If you have additional questions about irrigation or just about anything plant related, please contact your local UF/IFAS Extension Office.

Water is one of the most valuable natural resources and with the ever growing concern of climate change and the hot dry conditions Northwest Florida has already experienced this summer, every drop counts. One way you could combat this issue is by installing a rain barrel at your home. By having a rain barrel on hand, you can reduce stormwater runoff, potentially save money, and improve the health of your plants. Here’s what you need to know:
What is a rain barrel? A rain barrel is a container or storage tank that collects runoff water from a catchment area (a rooftop). They are typically placed under downspouts and capture the water runoff from your home’s gutters. The type of container used to make a rain barrel could be any type, but it cannot have stored chemicals prior to its use as a rain barrel.
Now that we know the definition, why exactly do people use rain barrels? For one, they aid in water conservation. Rain barrels help reduce the amount of potable water used for outdoor purposes, which is important during dry weather spells and areas known for drought conditions. There are also potential cost savings with using a rain barrel. By using the collected rainwater for watering your garden, cleaning outdoor surfaces, or even washing your car, homeowners could potentially reduce their water bills significantly. Having a rain barrel is also a Florida-Friendly way to gardening. Rain barrel usage co-aligns with the Florida-Friendly Landscaping Principles #2: Water Efficiently and #8: Reduce Stormwater Runoff. The use of rain barrels also aligns with sustainable living. It reduces the reliance on municipal water systems and promotes awareness of water usage and conservation.
To install a rain barrel, you will need to obtain a container or “barrel” that is several gallons large to store the water. You can purchase or make one yourself! It will need a secure lid to prevent debris and insects from getting inside. The barrel will need to be placed under a downspout from your home’s roof gutter systems. The ground will need to be level and the barrel could possibly need to be elevated to make accessing the water easier. Once you have placed the rain barrel in the location you want it, you will need to install a rainwater diverter on your downspout. This will help channel the rainwater into the barrel and can be adjusted once the barrel has become full of water. You will also want to install a spigot near the bottom of the rain barrel to access the water and an overflow valve of some sort. The overflow valve will help redirect excess water away from your foundation when the rain barrel becomes full. Maintenance of a rain barrel is generally very low but you need to check regularly for debris in the water and ensure all the mechanisms are functioning like they should be.
How can you use the water collected in a rain barrel? The most obvious answer would be to water your garden and outdoor plants. Rainwater is perfect for watering the lawn, your flowers, and vegetable gardens. The water quality of collected rainwater is often more beneficial for plants as it is non-chlorinated water. Rainwater is also great for indoor plants too as it decreases the amount of mineral build-up that can occur from using tap water.
By installing a rain barrel at your home, you are taking a small leap with significant environmental impact. It is an easy, cost-effective way to reduce your utility bills, conserve water, and contribute to sustainable living. For more information on rain barrels and how to install one, please visit:
While the Florida Panhandle isn’t considered a true tropical climate, now that the summer rains have started, it sure feels tropical outside. To create high performing colorful containers in these conditions, it’s wise to pick plants that hail from tropical climes – one of my favorites is Crossandra (Crossandra infundibuliformis).
Native to tropical Sri Lanka and India, Crossandra is built for hot, humid conditions. An evergreen subshrub growing about 3’ tall in its native range, Crossandra sports glowing orange flower clusters held high on stems that rise above deep green, glossy foliage – a very striking combination. These showy orange flowers arrive once temperatures heat up in the early summer and continue emerging en masse until cool nights stop the show in fall. While deadheading spent flowers can enhance Crossandra’s free-flowering nature, I haven’t found it totally necessary to ensure consistent flowering. In addition to being beautiful, Crossandra’s flower clusters are also attractive to a wide variety of pollinators, including butterflies and dragonflies.

Adding to Crossandra’s appeal, the species couldn’t be easier to grow if you give it the right conditions. Crossandra prefers to be sited in areas that receive ample sunlight but also get a reprieve from the hottest afternoon rays. This year, I grew one on a deck that receives sun from about 10 am – 2 pm and is then provided filtered shade from a large tree the rest of the afternoon; these conditions seem to be ideal. Crossandra performs best in moist, well-drained soil, making potting mix an excellent option. Daily watering in the summer combined with our (hopefully) frequent rainfall in July and August keeps it wilt-free. I also apply slow-release fertilizer at planting and then supplement with liquid fertilizer periodically throughout the summer. This, combined with regular irrigation, promotes healthy, vigorous growth, and allows the flower show to continue uninterrupted until cool weather finally draws the curtains.
Crossandra is a versatile plant in container gardens, shining in either the role of filler in larger containers or as a solo specimen plant in its own container. In mixed containers, play off of Crossandra’s orange flowers with partial sun foliage plants like Coleus, Elephant Ears, or Hawaiian Ti, or flowering annuals like Browallia ‘Endless Illumination’, Torenia (Wishbone Flower), Blue Daze, or Purple Heart Plant. While Crossandra does well in mixed containers, as a UF graduate, I prefer to stick it in my favorite blue pot for an orange and blue Gator themed solo container!
Regardless of how you choose to incorporate Crossandra into your garden’s design, it will reward you with summer-long orange flowers in a low-maintenance package. Simply place it in morning to early afternoon sun, give it ample water and adequate fertilizer, and enjoy this Florida Friendly Landscaping approved species. Plant one today!
