WaterBigleaf hydrangeas like the 'Dharuma' prefer consistently moist soil, so water deeply once a week, providing about 1 gallon of water for each plant. During hot and dry periods, you may need to water twice weekly. Avoid overhead watering to reduce the risk of leaf diseases; instead, water at the base of the plant. It's essential to ensure proper drainage as overwatering can lead to root rot. Adjust the frequency based on your climate and weather conditions, monitoring the soil moisture level regularly.
Light'Dharuma' hydrangea, like other bigleaf hydrangeas, thrives in partial shade, especially in the afternoon. Morning sun with dappled afternoon shade is ideal to protect it from intense heat, which can scorch the leaves. It can tolerate full sun in cooler climates if it's kept sufficiently watered but generally performs best with protection from harsh midday rays.
TemperatureThe bigleaf hydrangea 'Dharuma' prefers a temperature range between 65°F and 75°F but can tolerate down to about 50°F and up to 80°F. Temperatures below freezing can damage new growth, so winter protection in colder zones is necessary. Proper mulching can help insulate roots from sudden temperature drops.
PruningPrune your 'Dharuma' bigleaf hydrangea annually to maintain shape and encourage vigorous growth. The optimal pruning time is after blooming in mid-summer, as hydrangeas bloom on old wood. Remove dead or weak stems, and thin out crowded areas to improve air circulation. Pruning in late winter or early spring can remove flower buds and diminish blooming for the season.
CleaningAs needed
SoilThe best soil mix for a Hydrangea, commonly called hydrangea, should be rich, moist, and well-draining, with a high organic matter content such as compost or peat moss. The soil pH for hydrangeas should be acidic to slightly acidic, around 5.5 to 6.5, to help maintain the vibrant bloom colors.
RepottingHydrangeas should be repotted every 2 to 3 years or when the root system outgrows the current container. Choose a slightly larger pot and fresh potting mix to ensure the plant continues to thrive.
Humidity & MistingHydrangeas prefer moderate to high humidity levels, typically between 60% to 70%, which is necessary to support their lush foliage and robust blooms.
Suitable locationsIndoor
Provide bright indirect light and maintain even moisture.
Outdoor

Life cycleThe Hydrangea 'Dharuma', commonly known as the Dwarf Hydrangea, begins its life cycle as a seed that germinates in moist, well-drained soil in partial to full sun. After germination, the seedling grows into a young plant with distinctive foliage and begins to develop a root system. As it matures, the Dwarf Hydrangea enters a vegetative stage, producing lush leaves and eventually woody stems. The reproductive stage follows, typically in early to mid-summer, when the plant blooms with large, showy flower heads that can range from pink to blue depending on soil pH. After pollination, the flowers may produce seeds that can disperse to propagate new plants, completing the cycle. In autumn, the Hydrangea 'Dharuma' may experience a period of dormancy, losing its leaves in colder climates before resuming growth in the spring.
PropogationPropogation time
Spring-Early Summer
Propogation: The Hydrangea macrophylla 'Dharuma', commonly known as lacecap hydrangea, is typically propagated through stem cuttings. The most popular method involves taking a cutting from a healthy, non-flowering shoot in early to mid-summer when the plant's growth is vigorous. You should choose a stem that has several sets of leaves and make the cut just below a leaf node, about 5 to 6 inches (approximately 12.7 to 15.24 centimeters) long. Remove the lower leaves and dip the cut end in rooting hormone to promote root development. Then, insert the cutting into a pot with well-draining soil mix and water it thoroughly. The pot should be kept in a warm, humid environment with indirect sunlight until roots have developed, which usually takes about 2 to 4 weeks. Regular misting can help maintain humidity, which is crucial for successful rooting.
