Spring Care for Trees, Shrubs, and Lawns in Warmer Climates Seasonal Care In warmer climates, like the south, the southwest, and along many of our coastlines, spring doesn’t so much arrive as it accelerates. Soil temperatures rise quickly. Days lengthen. Buds swell and open fast. And with that early energy comes both opportunity and risk. Plants that never fully shut down over winter are already spending resources by the time spring begins. Insects emerge earlier than they do up north. Fungal diseases take advantage of warmth and moisture to spread quickly. Lawns green up fast, but can just as quickly thin or stress if they don’t get the right care at the right time. The goal of spring care in a warm climate isn’t to push growth, it’s to guide it. Our job as property owners is to support healthy momentum now so your landscape stays resilient through heat, storms, and the longer summer ahead. Start by Seeing What Winter Left Behind Before treatments, fertilizers, or pruning tools come out, spring should begin with observation. Walk your property. Winter debris like fallen branches and extra leaves can linger longer in warm regions, especially where growth continues year-round. Clearing most of it allows air to move through your landscape, reducing the moisture buildup that insects and fungal diseases love. At the same time, it’s important to leave a small layer of organic material in place to support soil health and beneficial microbes. Once things are cleared, the official inspection begins. Check your trees for scale insects, mites, aphids, and caterpillars. If they’re there, you’ll be able to see them with the naked eye. Also check for leaf spots, mildew, and blight on new growth. If you notice issues now, it’s too late for treatment this season. The best approach is to plan ahead and apply preventive fungicide treatments as early as possible. Spring is also when mosquitoes and ticks begin establishing themselves. Reducing standing water and dense vegetation now can make a noticeable difference in how comfortable your outdoor spaces feel later. Clearing these problem areas now prevents issues from getting out of hand later. Mulch with Intention, and Go Easy Mulch retains soil moisture, buffers temperature swings, and slows nutrient loss during heavy rain. These benefits matter everywhere, but they’re even more important in warmer climates than in cold areas. And more mulch is not better. A clean, even layer of mulch that runs about two to three inches deep is plenty to get the job done. Piling mulch high against trunks (aka “volcano mulching”) traps moisture where it doesn’t belong, leading to decay, insect activity, and long-term stress. Keeping mulch pulled back, however, allows bark to stay dry and lets roots breathe, which is especially important as soils warm. Prune Your Trees Strategically In warm regions, spring pruning is less about shaping and more about strategy. Removing dead, damaged, or poorly structured branches early improves airflow and reduces risk during wild spring and summer storms. Thoughtful thinning like this can lower wind resistance and help trees hold their form as weather becomes more unpredictable. But heavy cuts can push trees and shrubs into producing soft, vulnerable growth that struggles later in the season, so you always need to use a gentle touch.It’s also important that you wait to prune flower plants until after they bloom, so next year’s buds aren’t sacrificed. And in general, it’s often best to bring an ISA Certified Arborist on for your pruning needs. We’re trained to protect your property and everything around it. Be Careful with Warm Season Grasses Warm-season grasses respond fast once temperatures rise. That can be a blessing or a problem, depending on your approach. First, fertilizing too early encourages shallow growth and increases disease pressure, so it’s important to let your lawn green up before you feed it. Mowing should be regular but measured, with sharp blades and proper height to protect roots from heat stress later. It’s also smart to get your irrigation dialed in now. Watering works best when it’s slow, deep, and infrequent. But overwatering can cause root rot and fungal issues down the line, so spring is the ideal time to adjust schedules, fix coverage issues, and get your watering routine working. Feed Roots, Not Just Leaves If you live in a warmer climate, use a steady and deliberate approach to fertilization to get the best results. Slow-release nutrients like ArborKelp® and ArborHealth® are great for this. They support healthy foliage while strengthening natural defenses against insects and disease, and they’re particularly effective in warmer climates like ours. For newly planted, stressed, or high-value trees, biostimulants are generally a good option because they can improve root development and help plants manage environmental stress effectively. Stay Ahead of Weeds Before They Take Root In warm climates, weeds establish in the spring and persist throughout summer. Pre-emergent treatments applied in spring can help stop weed seeds before they germinate, but the key is consistency and timing. Create a protective barrier early to prevent weeds from finding their opening. Spring: The Season that Sets the Tone The choices you make now determine whether trees grow steadily or struggle, whether lawns stay dense or thin, and whether small issues stay manageable or become season-long problems. With thoughtful care in early spring, your landscape is better equipped to handle heat, humidity, and whatever the rest of the year brings.
