Savannah's Seasonal Tree Care Calendar: Month-by-Month Guide

Tree care in Savannah follows the rhythm of the seasons. The right task at the right time supports tree health, prevents disease, and reduces storm risk. The wrong task at the wrong time can stress or even kill trees that would otherwise thrive. This month-by-month guide is calibrated for coastal Georgia, where the growing season is long, winters are mild, and hurricane season demands its own preparations.

January. Dormant season is in full effect. This is the best month for major structural pruning of most hardwoods. Live oaks, maples, sycamores, and most ornamental trees can be pruned now with minimal stress. Inspect trees for storm damage from winter cold fronts. Plant new bare-root trees if you can find them, though container-grown trees are more common in this market. Check stakes on trees planted in the last year and remove any that have been in place more than twelve months.

February. Continue dormant pruning. This is also the right month for fruit tree pruning, particularly peaches, plums, and apples, which need annual structural work for good fruit production. Apply dormant oil to fruit trees and ornamentals with scale or aphid problems. Plant new trees throughout the month, taking advantage of cool soil and adequate moisture before spring growth begins. Inspect for fungal cankers and other dormant-season indicators.

March. Dormant pruning window is closing. Finish any major structural work early in the month. This is the right time to fertilize newly planted trees with a balanced slow-release fertilizer, but established trees in good health usually do not need fertilization. Begin watching for spring leaf-out across deciduous species. Live oaks will begin dropping last year's leaves and pushing new growth this month. Plan any cabling or bracing work for completion before the spring growth flush.

April. Spring is fully underway. New growth is vigorous and trees are using their energy reserves. Avoid major pruning except for clearly dead material and any storm damage from spring thunderstorms. Begin the pre-hurricane season inspection of all trees within striking distance of structures. Schedule any necessary pre-season reduction pruning for May or June. Apply mulch to root zones, but keep mulch off the trunk to avoid bark damage and rot.

May. The pre-hurricane season window is the priority this month. Get an arborist on the property if you have any concerns about trees near structures. Address codominant stems, dead limbs over roofs, leaning trees, and any species-specific risks. Confirm insurance documentation is up to date with current photos of major trees. Water newly planted trees during dry spells, with a slow deep soak weekly rather than daily light irrigation.

June. Hurricane season officially begins. Pre-season pruning work should be largely complete. Begin watching for early signs of summer diseases, especially leaf spots, anthracnose, and powdery mildew on susceptible species. Continue watering new plantings. Monitor mulch coverage and refresh where it has thinned. Light deadheading of crape myrtles will encourage rebloom.

July. Peak summer heat and humidity. Tree work should be limited to deadwood, hazard reduction, and emergency response. Watch for fungal disease pressure. Watch for stress symptoms on trees with construction or grade change history. Check for bark beetle activity on pines, especially trees that look stressed. Continue watering new plantings during dry stretches. Avoid major root zone disturbance.

August. Heart of hurricane season. Storm preparation should be in place. Monitor weather forecasts and have an emergency tree service number saved before you need it. Continue limiting tree work to essentials. Watch for tropical storm and hurricane forecasts and begin staging tarps, generators, and supplies if a storm enters the Atlantic basin. Trees stressed by summer drought may begin showing early decline symptoms.

September. Hurricane peak month historically. Stay alert to forecasts. Continue water monitoring during dry stretches, which are common in early September before fall rains arrive. Begin watching for fall color development in deciduous species, though Savannah's fall color is generally muted compared to upland Georgia. Plan dormant season pruning priorities now while issues are visible in full leaf.

October. Hurricane season continues but threat diminishes through the month. Inspect trees for any storm damage from the active season and plan corrective pruning for the dormant season. Begin reducing watering frequency as temperatures moderate and rainfall typically increases. This is a good month to plant new trees, taking advantage of cooling soils and adequate fall moisture. Container-grown specimens establish well planted in October.

November. Dormant season begins for most deciduous species. Major structural pruning window opens. Schedule any large pruning projects now to spread work across the dormant months. Apply fresh mulch to root zones for winter protection. Inspect trees one final time for any storm damage that should be addressed before winter. Continue planting new trees through the month.

December. Full dormant season. Excellent month for major pruning, planting, and structural work. Inspect for damage from any winter storms. This is also a good month for cabling and bracing work, when trees are not bearing leaf load. Plan next year's tree care schedule and budget. Review insurance documentation and update photos.

Year-round practices. Watch for hazard indicators continuously: new leans, fungal growth at the base, dramatic dieback, soil cracks at the root plate. Document everything with dated photos for insurance purposes. Build a relationship with a qualified arborist who knows your property over time. The trees you tend monthly are healthier and safer than the trees you only notice when something goes wrong.

Savannah's growing conditions are generous, and trees here respond to consistent care with vigor that gardeners in less hospitable climates can only envy. The seasonal calendar is your map to that response.
