Care Instructions:

  • Light: Thrives in full sun to part shade; at least 6 hours of direct sunlight daily ensures optimal blooming.
  • Soil: Prefers well-drained, fertile soil but adapts to sandy or clay soils.
  • Water: Water regularly during the first growing season to establish roots. Once established, it is moderately drought-tolerant but benefits from occasional deep watering during dry periods.
  • Pruning: Prune in early spring to maintain shape and encourage fresh growth. As flowers bloom on new wood, annual pruning enhances flower production.
  • Fertilizer: Use a balanced, slow-release fertilizer in early spring to support lush growth and vibrant blooms.
  • Pests/Disease: Resistant to most common pests and diseases. Ensure proper air circulation to prevent fungal issues and treat any pests like aphids or beetles promptly with an organic solution.

The White Althea is a symbol of grace and simplicity, perfect for adding elegance to any garden. Whether used as a privacy screen, a backdrop for colorful plants, or a standalone statement piece, this low-maintenance shrub brings effortless beauty and charm to your outdoor space.

How to Plant
STEP 1) First, decide on a planting location. Consider carefully what kind of sun, soil, and growing-space your tree or shrub will need.
STEP 2) Once you've located the perfect spot, the hole you are digging must be at least double the width and as deep as the root system you are planting.
STEP 3) Remove the plant from the pot and place the root ball in the hole. The top of the root system should be level with the ground. Before placing the tree or shrub in the hole, use your hands to gently break up the root system.
STEP 4) Once the plant is in place, backfill the hole with native soil and any leftover potting material.
STEP 5) Pack down the soil to eliminate any air pockets.
STEP 6) When finished, water thoroughly.
Care Guide

For the first growing-season, water on a weekly schedule. Once the plant is established, water only as needed. Since plants bloom on new growth, shaping or pruning can be done at any time. However, pruning is usually not required since the plant grows slowly and keeps a tight upright form. Prune in late winter or early spring in northern climates. Frequent severe pruning gives fewer but larger flowers; no or little pruning gives many smaller flowers.
