March Lawn, Garden, & Landscaping Tips 2023

Our March Lawn Garden and Landscaping Tips revolve around the fact that March ushers in longer days with warming soils that lift lawn turf from slumber and encourage new growth throughout the landscape.

Get To Pruning, Planting, & Watering:
We’ve likely seen our last frost and freeze days. New growth appears everywhere, from the oak trees’ recent leaf and catkin drop to those woody stems pruned back from winter damage. Plants with brittle stems that have no green remaining, we can conclude, were lost to old man winter and can now be safely replaced.

The University of Florida IFAS Extension office recommends March edible plantings of Arugula, Eggplant, Kohlrabi, Ginger, Peppers, Swiss Chard, Tomatillo, Tomatoes, Boniato, Spinach, Sweet Potatoes, Lima Beans, Bush Beans, and Pole Beans, Cantaloupes, Carrots, Corn, Cucumbers, Okra, Onions, Peanuts, Peas, Radish, Squashes, and Watermelon.

Emerging from a Record-Dry Winter
Besides the cold Winter, your lawn, garden, and landscape damage could have been from lack of precipitation. “Retallying the winter stats of 2022-23, in Jacksonville, we had our 72nd warmest December, the 41st warmest January and the sixth warmest February,” according to News4Jax Weather Insider. “Add it all up, and we had the 16th warmest Winter! The bigger winter story was the total lack of rainfall. Just 3.85 inches of rain the entire Winter!” That’s compared to an average winter rainfall in Jacksonville of 9.5″. Check your irrigation system for proper operation and get ready to increase your watering regimen.


In Duval County, water restrictions lessen during Daylight Savings Time, allowing twice-per-week residential landscape irrigation with no limits for new landscapes and hand watering. “Residential properties with even-numbered addresses or those ending with A-M** may water on Thursday and Sunday; properties with odd-numbered addresses, those ending with N-Z*, or properties with no street address may water on Wednesday and Saturday, according to the City of Jacksonville. “Non-residential irrigation is only permitted Tuesday and Friday. Irrigation is not permitted between 10 am and 4 pm.” Be vigilant in ensuring your lawn and garden are sufficiently watered. Earth Works lawn care division recommends two weekly rain or watering events for a healthy lawn.

Chinch Bug Threat Strong During Drought Conditions
Drought conditions can increase the chance of chinch bugs infestation in your St. Augustine turf. Chinch bug season in North Florida is typically March through November. “Chinch bug damage can be confused with certain lawn diseases or other physiological disorders,” according to Texas A&M. “For example, brown patch is a common disease affecting the leaf blades of St. Augustinegrass. Brown patch symptoms, however, usually occur in a circular or semi-circular pattern, as opposed to the irregular-shaped areas of dead and dying grass that result from chinch bug feeding. Chinch bug damage also can be difficult to distinguish from that caused by drought.”

When to Fertilize?

Palms: For palms we recommend quarterly fertilization with heaviest feeding in Fall and Spring and lighter fertilization in Spring and Winter. We recommend: Palm Tone by Espoma and Jacks Palm Food 16-5-25 that’s water soluble with micronutrients.

Birds of Paradise: These heavy feeders require fertilization to maximize foliage and flowering capacity. While the UF/IFAS recommends quarterly fertilization Tropical Plants of Florida recommends bi-weekly fertilization in Spring and monthly during the Summer months.

Crape Myrtles: Crape Myrtles are heavy feeders that respond well to liquid and granular balanced fertilization as often as every two weeks during Spring and Summer. You’ll want to use a balanced fertilizer such as Jacks All Purpose 20-20-20.

Roses: Consider monthly fertilization from mid-February through November for optimum foliage and blooms on your roses. Roses are highly susceptible to powdery mildew and leaf spot that you can curtail damage from with regular Bonide copper fungicide treatments.

Fruit Trees: “You can apply a slow-release citrus fertilizer in March, June and September or apply 6-6-6 or 8-8-8 starting in March once every six weeks through September,” according to Becky Jordi, the Nassau County extension director and horticulture agent. “No fertilizer should be applied from October through February.” We recommend Jacks Citrus Feed.

Weed & Feed Facts:

We are at the right time to consider Weed & Feed fertilizer. They typically contain a pre-emergent herbicide for preventing weeds from germinating. The “N” component of fertilizer’s NPK macro-nutrient makeup is nitrogen, which is not necessary in high concentration at this time. However, phosphorus and potassium (PK) can provide current benefits for root health.
