rhododendron

Water Rhododendron 'Anna H. Hall' regularly and deeply to ensure good growth and flowering. Aim to keep the soil evenly moist but not soggy. Water every 7-10 days during warmer months (April-September) and every 10-14 days during cooler months (October-March). When watering check the soil by inserting your finger into the soil to determine if the soil feels dry or moist. If the soil feels dry, water the rhododendron until the soil is evenly moist. Then allow to drain without overwatering. Avoid getting water on the leaves to help minimize the chance of disease.

Rhododendron 'Anna H. Hall' requires bright direct sunlight during the morning hours and light shade during midday and afternoon. This highly versatile shrub prefers temperatures of 65-75°F (18-24°C) and should not be exposed to prolonged direct sun or harsh afternoon sunlight. During the growing season (April - September), it requires 6-8 hours of sunlight per day in order to reach its ideal colors and shape. When the temperatures start to cool off after the fall, this plant should receive 2-4 hours of direct sunlight per day to encourage strong growth with dark green foliage.

For optimal growth, Rhododendron 'Anna H. Hall' should be pruned once a year during the late winter or early spring when the plant is still dormant. Pruning should be light - no more than 10-15% of the total branches should be removed. This will maintain the size and shape of the plant while allowing it to get the necessary sunlight and air circulation to keep it healthy. When pruning, it is important to focus on removing dead, broken, or diseased branches and less on shaping the plant. Also, flower buds should be left intact because they will produce the desired blooms in the spring.
