Melaleuca Mulch


You may have heard of Melaleuca mulch, but wondered what it is, and why it is an environmentally-friendly mulch.

Melalueca mulch contains bark and wood from Melaleuca quinquenervia, an invasive exotic tree. The Melaleuca, or punk tree, was introduced to Florida over 100 years ago, and since then has taken over parts of South Florida. The Everglades has been threatened by the dense stands of Melaleuca as they move quickly by wind-dispersed seed and form thick monocultures. These monocultures damage the ecosystems that they overtake by displacing native flora and fauna. They also are very susceptible to fire and burn quickly. The native wildlife that depend on native vegetation for survival are pushed out of the area, and migrating birds suffer.

But luckily something is being done about the Melaleuca infestation. Numerous organizations use a multi-faceted approach to the eradication of the trees in South Florida. Biological control (using a plant's natural enemy), mechanical control and herbicides are used. There are companies that create a garden mulch out of the removed and composted trees. This mulch is environmentally-friendly because it is a usable product created from a potential waste product. The high heat of composting ensures that no Melaleuca trees will sprout up in your yard. This organic (it breaks down in the garden, benefiting the soil) mulch is a shredded wood mulch that resists floating and retains a light brown color. It has also been shown to settle the least in University of Florida research. This means that it retains its beneficial qualities for a longer period of time and would not need to be replenished as often as other mulches. This means that Melaleuca is also a budget-friendly mulch!

Just like all mulches in the landscape, Melaleuca should be applied 2-3 inches deep and never touch the base of the plant. The benefits of mulch are numerous and a University of Florida study shows that termites prefer not to eat Melaleuca mulch. Weed suppression, improved soil structure, soil moisture retention, and increased landscape beauty are some of the many reasons that mulch is so important in the landscape. To purchase Melaleuca mulch contact the Polk County Master Gardeners. The mulch is $3.00/bag from the Master Gardeners at the UF/IFAS Polk County Extension Service at 1702 Highway 17 South in Bartow. Call (863) 519-8677 for more information. Proceeds benefit the Polk County Master Gardeners.

Interactive Way to Learn About Polk's Natural Wonders

A new interactive feature on the Lake Wales Ridge will teach the eager learner all about the unique flora and fauna of the ridge. Click on the animals and plants to learn about their habitat. There is also a video and a list of cool facts about the Lake Wales Ridge:

LAKE WALES RIDGE FACTS

Where: Polk, Lake, Highlands. Osceola counties
Size: The Lake Wales Ridge stretches for 100 miles. Scrub habitat once covered 341,000 acres, but today scientists estimate only 44,157 acres remain in fragments throughout the area.
Significance: Habitat contains one of largest concentrations of rare and endangered species in the United States.
National importance: First location in the United States where a national wildlife refuge was established primarily to protect rare plants.
Global importance: Many of the species on the Lake Wales Ridge are found nowhere else on the planet.
Number of endangered/threatened species: 38.
Why: The rare species evolved in isolation during the thousands of years the Lake Wales Ridge was a chain of islands when the rest of Florida was underwater.

Winter Water Conservation Tips


As cool weather approaches it is time to change the way we irrigate our lawns and landscapes. Even though you may not notice, many plants (including your grass) will become semi-dormant in the winter months. When temperatures are cool, plant growth is limited and irrigation frequency should change.
If you are not sure when to water in the winter, always remember that your plants will let you know when they need it; you just have to learn how to read the signs. When it comes to watering your plants, look for signs of stress before watering. Wilting leaves are the best indicator. If you notice wilting leaves, water at the end of the day or the next morning. The best way to reduce the need for watering is to install drought-tolerant plants.
The height that you mow your lawn is directly related with how much water your grass will need. Mow your grass high and cut no more than 1/3 of the grass blades at each mowing. This practice encourages a much deeper and stronger root system. Also remember to give your lawn a break in the winter. In the winter, lawns do not need weekly mowing and even in Florida lawns go semi-dormant and need much less water.
When watering with a sprinkler system, the most efficient systems are drip or micro-spray systems. These systems are easy to install and to maintain. By choosing and maintaining these systems correctly, you can reduce your water bills, fungal diseases and maintenance requirements.
Always remember to follow the current watering restrictions when irrigating your lawn and landscape—it is our job to conserve water for Florida’s future!
Refer to the Guide to Florida-friendly Landscaping for other watering information or contact the Florida Yards and Neighborhoods Program Coordinator at the UF/IFAS Polk County Extension Service.

Holiday Plants


As the holidays draw near and the weather cools, gardeners turn to winter-blooming plants. Both the holiday cactus and the poinsettia are at their peak this time of year. You may own or purchase one of these plants (or be lucky enough to receive one as a gift) and need to know how to care for them. The following care guides are also a great thing to include in a poinsettia that you may give as a gift. Dr. Shibles, the Polk County Urban Horticulturist, has provided the following information on holiday plants.
