Professional diagnosis and treatment in Ellicott City
Call 410-992-8680Many plant problems look similar but require completely different treatments. Yellowing leaves might indicate nutrient deficiency, root disease, drought stress, overwatering, or pest damage. Applying the wrong treatment wastes money while the real problem worsens. Professional diagnosis identifies actual causes so treatment addresses root problems—not just symptoms.
Examine affected plants thoroughly—symptoms on leaves, stems, and roots. Evaluate vigor, sun exposure, drainage, soil conditions, pest presence, and recent weather events.
Identify the specific disease, pest, or cultural problem. 39 years of experience means we recognize common issues immediately—boxwood blight, scale on hollies, winter injury, chlorosis. Samples collected for lab analysis when needed.
Recommend appropriate treatment with full explanation of cause, what treatment involves, expected results, and cost. You make informed decisions before anything begins.
MDA-licensed crews apply targeted products using professional equipment. Timing scheduled at optimal points based on pest life cycles, disease patterns, and plant growth stages.
Monitor results and develop long-term health care plans. Some issues require ongoing preventative programs. Prevention is always more effective and less expensive than treating severe problems.
Devastating fungal disease spreading through Maryland. Causes rapid leaf drop and stem dieback. Early diagnosis critical—aggressive sanitation can slow progression. Severe cases require removal.
Common on hollies, euonymus, magnolias. Suck plant juices, cause yellowing and dieback. Produce sticky honeydew attracting sooty mold. Requires properly timed treatment during crawler stage.
Broadleaf evergreens like azaleas, rhododendrons, hollies suffer desiccation or freeze damage. Often looks devastating but many plants recover with proper pruning and care.
Fungal and bacterial diseases cause circular spots, often with yellow halos. Severe infections weaken plants. We identify specific pathogens and recommend fungicide programs when warranted.
Tiny arachnids cause stippling and bronzing, especially during hot dry periods. Particularly problematic on arborvitae, junipers, spruces. Heavy infestations can kill branches.
Alkaline soils limit iron availability. Acid-loving plants like azaleas and rhododendrons develop yellowing with green veins. A nutritional problem—requires soil acidification and iron supplementation.
Inspect landscape plants throughout the growing season. Catch problems in early stages when treatment is most effective—before they become severe.
Dormant oil applications control overwintering pests. Preventative fungicide programs protect disease-prone plants. Anti-desiccant sprays protect broadleaf evergreens through winter.
Many problems stem from improper care—wrong watering, poor drainage, inadequate fertilization. Our programs include guidance on practices that keep plants naturally stress-resistant.
Well-nourished plants resist problems better than stressed ones. Tailored fertilization programs ensure proper nutrition throughout the growing season.
Early diagnosis and treatment save plants and money
Call 410-992-8680Identifies real problems, not just visible symptoms. Ensures treatment addresses actual causes and produces effective results.
Experience means selecting appropriate products, methods, and timing for each issue. We know which problems warrant intervention versus monitoring.
MDA-licensed crews with proper equipment and training. Thorough coverage, correct concentrations, safe handling that DIY often lacks.
Mature landscape plants can cost hundreds to replace. Professional care saves valuable plants when problems develop.
Healthy plants enhance property value and create beautiful outdoor spaces. Professional care keeps your landscape an asset, not a frustration.
Call if you notice: leaves turning yellow, brown, or developing spots; branches dying back; unusual growth patterns; wilting despite adequate water; insects or webbing on foliage; sticky residue; sudden leaf drop; or stunted growth. Early intervention is critical—plants are much easier to save when problems are caught early. We'd rather assess a healthy plant than have you wait until problems become irreversible.
It depends on the problem and how advanced it is. Scale insects, spider mites, and many fungal diseases respond well to early treatment. Boxwood blight is extremely difficult to control once established. Winter injury often looks devastating but many plants recover with proper pruning. We'll honestly evaluate whether plants can be saved, what treatment involves, and expected results. Sometimes removal and replacement is the most practical solution.
Yes, when applied properly by licensed professionals. Our MDA Pesticide License #23902 requires training in safe application and environmental protection. We use targeted treatments minimizing broader impacts—many products like horticultural oils and insecticidal soaps are very low-impact. We provide clear post-treatment precautions and emphasize cultural controls to minimize pesticide use wherever possible.
Costs vary by problem severity, number of affected plants, and treatment required. Simple issues like treating a single shrub for scale run $75–150. Preventative programs and major multi-treatment issues cost more. Detailed estimates provided before any treatment begins. Investing in prevention or early treatment is far more cost-effective than replacing dead plants—a mature shrub can cost $200–500+ to replace while treatment to save it often costs significantly less.
