December Lawn & Garden Tips

December lawn & garden tips begin with recognition that this is a predictably cool & dry weather month that’s great for planting large shrubs and palms and for working on landscape designs and projects.  As the weather can change rapidly keep up to date with weather forecasts and be prepared to protect your tender plants and pets well ahead of frost and freezing temperatures. 

The National Weather Service predicts below-average precipitation throughout the Southern United States in December. While drying out is suitable for reducing the threat of lawn fungus that’s at its worst on cool, humid nights, too little water and watering at the wrong time of day can also cause problems.

Earth Works recommends two lawn watering events per week in December. If you don’t get two rain events per week supplement with irrigation and hand watering. New lawns and landscapes require daily watering the first month to get established. Irrigation is restricted to once per week in Jacksonville, coinciding with a return to Standard Time that began on November 6.
Duval County watering ordinance includes:
1) No watering from 10 a.m. to 4 p.m.
2) Odd number addresses, or addresses ending with letters N-Z, or no address may water only on Saturday.
3) Even number addresses or those ending with A-M may water only on Sunday.
4) Non-residential addresses may water only on Tuesday and
5) Apply up to ¾-inch or less of water one time per week.


Proper care of your lawn during dormancy will directly impact its health in Spring and Summer.

The three macro-nutrients listed on the label of all fertilizers are nitrogen, phosphorus, and potassium, abbreviated as NPK. 


If choosing a Winterizing lawn fertilizer, we only recommend an NPK with phosphorus and potassium. “Adding phosphorus to soil low in available phosphorus promotes root growth and winter hardiness, stimulates tillering, and often hastens maturity,” according to University of Nebraska Plant & Soil elibrary. “Potassium is a vital component of numerous plant functions, including nutrient absorption, respiration, transpiration, and enzyme activity.” Both phosphurus and potassium are essential for plant maintenance and support, according to the Noble Research Institute. For Winter we only recommend nitrogen-free formulations.

It’s also essential to know your soil pH when supplementing with fertilizers. These macro-nutrients are only fully bioavailable at a pH of 6.5 or above and decreasingly available below. “In a very acid soil of pH 5.0 only 40% of the nitrogen is available, 35% of the phosphorus and 50% of the potassium,” according to Allotment “Increasing to an average plot’s pH 5.5 takes the nitrogen and potassium up to 70% availability but the phosphorus is still only at 45% availability. It’s not until the pH hits 6.5 that all the big 3 nutrients are fully available to fuel the plants.”

Now is an excellent time to consider BOOKING soil AERATION & TOP DRESSING service for your lawn ahead of Spring with the Earth Works Lawn Care department. Contact us to get you scheduled.

December Lawn & Garden Tips promoting Earth Works Annuals

As previously mentioned December’s cold and dry weather is perfect here in Northeast Florida for planting palms, citrus, and other trees. December and throughout the Winter months is also the time of year to introduce colorful annuals in an otherwise often dormant and bland landscape. Earth Works has a large selection of annuals for your garden beds including petunias, violas, snapdragons, lambs ear, decorative kale, and Dusty Miller. For December we also have beautiful varieties of poinsettias and Anthurium with their long-lasting, heart-shaped flowers in stock.

Become familiar with the cold tolerance of your plants and the threat of chilling temperatures above freezing for each. Learn more. Getting your plants acclimated to indoor living after being brought inside requires extra attention to their light and watering needs along with pest management. Our heating systems create far different conditions from those our outdoor plants are accustomed to. Inspect your plants from soil up through the leaves before bringing indoors. You don’t want a pest or disease problem with one plant to damage others by placing together indoors in tight quarters. Be prepared to adjust your plants watering needs, rotating to assure adequate lighting and away from drafts throughout the Winter period.

Helpful Cool Weather Tips for Pond Owners:

Winter is the best time to schedule your landscape design consultation to prepare and plan and schedule your installation ahead of the busy Spring and Summer season. With a landscape design consultation and drawing you are better able to budget all or phases of your landscaping wants and needs from improved curb appeal to new plantings, water features and all that goes into making your yard perfect for your vision of high quality outdoor living. It can take weeks, even months, to schedule and implement your plan especially if you wait until the busiest times for the landscaping industry. Don’t wait too late to get your project designed and scheduled to meet your desired completion date.
