Watering frequency depends on the plant size, potting mix, and environmental conditions. Generally, hydrangeas prefer evenly moist soil. Water when the top inch of soil feels dry, typically 1-2 times per week. Avoid letting the soil dry out completely or become waterlogged.

How Should Indoor Hydrangeas Be Fertilized?

Use a balanced, water-soluble fertilizer formulated for flowering plants. Feed indoor hydrangeas every 2-4 weeks during the growing season (spring to early fall). Reduce feeding in late fall and winter when growth slows. Always follow the manufacturer’s instructions for proper dilution and application.

What Are Common Pests And Diseases Affecting Indoor Hydrangeas?

Common pests include spider mites, aphids, and whiteflies. Regularly inspect plants for signs of pests, such as webbing or yellowing leaves, and treat with insecticidal soap or neem oil as needed. Hydrangeas are also susceptible to powdery mildew and leaf spot diseases, which can be managed by improving air circulation and avoiding overhead watering.

How Should Indoor Hydrangeas Be Pruned?

Pruning indoor hydrangeas is mainly for shaping and rejuvenation. Remove spent flowers by cutting just above a pair of healthy leaves or buds. In late winter or early spring, prune back leggy or weak growth to encourage bushiness. Avoid heavy pruning, as it may reduce flowering.

Can Indoor Hydrangeas Change Flower Color?

Yes, the flower color of hydrangeas can change based on soil pH. Acidic soils (pH below 6) produce blue flowers, while alkaline soils (pH above 7) produce pink flowers. To alter flower color, amend the soil accordingly with additives like aluminum sulfate for blue flowers or lime for pink flowers.

How Can Indoor Hydrangeas Be Encouraged To Bloom?

Indoor hydrangeas bloom on old wood, meaning buds form in the previous growing season. To encourage blooming, provide consistent care including adequate light, proper watering, and occasional fertilization during the growing season. Ensure the plant experiences a dormant period with reduced watering and cooler temperatures in winter to promote flower bud development.
