Arboricolas are versatile, evergreen shrubs or small trees known for their glossy, palmate leaves, which give them a lush, tropical appearance. They are ideal for use as hedge plants, in container gardens, or as indoor houseplants due to their moderate size and ease of care.
Planting
- Location: Plant Arboricolas in a location that receives partial shade to full sun. In Southwest Florida, they benefit from some protection from the intense afternoon sun, especially in the hottest months.
- Soil: They prefer well-draining, fertile soil with a slightly acidic to neutral pH. Arboricolas are adaptable but thrive in soil that retains moisture without becoming waterlogged.
- Spacing: If planting as a hedge or in groupings, space Arboricolas about 3-4 feet apart to allow for mature spread.
Watering
- Frequency: Water regularly to keep the soil evenly moist, particularly during the hot, dry seasons. They are somewhat drought-tolerant once established but perform best with consistent moisture.
- Method: Water at the soil level to avoid wetting the leaves directly, which can promote fungal diseases.
Fertilizing
- Schedule: Fertilize Arboricolas three times a year (spring, summer, and early fall) with a balanced, slow-release fertilizer that includes micronutrients.
- Application: Apply the fertilizer around the base of the plant, extending to the outer edge of the leaf canopy. Avoid direct contact with the trunk and leaves.
Pruning
- Timing: Prune in late winter or early spring before the onset of the growing season. Additional light pruning can be done throughout the year to shape the plant or control its size.
- Purpose: Pruning helps to maintain a tidy appearance, encourages bushier growth, and removes any damaged or diseased branches.
Pest and Disease Management
- Common Pests: Arboricolas can be susceptible to pests such as spider mites, mealybugs, and scale insects. Regular inspections and prompt treatment with insecticidal soaps or neem oil can manage these issues effectively.
- Disease Prevention: Ensure good air circulation around plants and avoid overhead watering. Keep the area around the plants clean and free of debris to minimize the risk of fungal diseases.
Tips for Maximum Health
- Mulching: Apply a 2-3 inch layer of organic mulch around the base of the Arboricola to help maintain soil moisture, regulate soil temperature, and suppress weed growth. Keep mulch a few inches away from the stem to prevent rot.
- Container Growing: Arboricolas do well in containers. Choose a pot with good drainage holes and use a well-draining potting mix. Monitor watering closely, as container plants may dry out more quickly.
Wind and Salt Tolerance
Protection: Arboricolas have moderate tolerance to wind and can withstand salt spray, making them suitable for coastal environments. However, in areas prone to high winds, such as those experienced during hurricanes, provide protection to prevent damage.
Winter Care
- Protection: In Southwest Florida, Arboricolas generally do not need winter protection as they tolerate the mild climate well. However, during unexpected cold snaps, protect younger or more exposed plants with frost cloth.
- Watering: Reduce watering in the cooler months as the plant’s growth slows and the evaporation rate decreases.
