Growing camellias successfully requires understanding their specific needs, but these elegant and enduring flowering shrubs are among the most rewarding plants you can add to your garden. These evergreen beauties produce stunning blooms during the cooler months when most other plants have gone dormant, making them treasured additions to winter landscapes. Growing camellias with proper care allows them to become family heirlooms, living for centuries and gracing generations with their spectacular flowers. This comprehensive guide covers everything you need to know about growing camellias successfully.
Understanding Camellias: An Overview
Practical tips for growing camellias can be found at Gardening Know How.
For more detailed information about growing camellias, visit the American Camellia Society.
These remarkable plants belong to the Theaceae family and originate from eastern Asia, where they’ve been cultivated for over a millennium. While they’re most at home in warmer climates (USDA zones 7 through 9), some varieties can thrive in zone 6 with proper protection. Camellias grow slowly but steadily, eventually reaching heights of 2 to 12 feet depending on the specific variety you choose.
The most popular species include Camellia japonica, known for its large, showy flowers, and Camellia sasanqua, which tends to bloom earlier and can handle more sunlight. Both types offer an incredible range of flower colors, from pure white and soft pink to deep red, vibrant yellow, and even lavender tones.
Choosing the Perfect Location
Research-based information on growing camellias is available through University of Georgia Extension.
Success with camellias begins with selecting the right spot in your garden. These plants prefer locations that receive filtered sunlight or dappled shade throughout the day. Think of planting them beneath tall trees with open canopies that allow light to filter through, similar to their natural woodland habitats.
Camellia sasanqua varieties are more tolerant of direct sunlight than their japonica cousins, but even these benefit from some afternoon shade in hotter regions. When planning your garden layout, space multiple camellia plants at least five feet apart to prevent competition for water and nutrients. This spacing also ensures adequate air circulation, which helps prevent disease issues.
Soil Requirements and Preparation
Additional information about growing camellias is available from Clemson University Extension.
Camellias thrive in soil that’s rich in organic matter, consistently moist but never waterlogged. The ideal soil pH ranges from 6.0 to 6.5—slightly acidic, similar to what azaleas and rhododendrons prefer. If your garden soil is heavy clay that doesn’t drain well, consider growing camellias in containers instead.
When preparing the planting site, dig a hole that’s twice as wide as the root ball but only as deep as the container the plant came in. Avoid the temptation to add amendments directly to the planting hole; instead, incorporate well-rotted compost or aged manure into the top few inches of soil around the planting area. This encourages roots to spread outward rather than staying confined to a small amended zone.
Watering and Moisture Management
Maintaining consistent soil moisture is crucial for camellia success. These plants don’t handle drought well, especially during the critical bud development period in late summer and early fall. Inadequate water during this time results in fewer flowers and blooms with fewer petals.
Aim to provide about one inch of water per week, ideally split into two watering sessions. This deep, infrequent watering encourages roots to grow deeper into the soil. Apply a three-inch layer of organic mulch around the base of your plants (but keep it away from the trunk) to help moderate soil temperature, retain moisture, and suppress competing weeds.
Temperature and Climate Considerations
Camellias are surprisingly cold-hardy considering their elegant appearance, but they do have limits. Most varieties can withstand temperatures down to about 10°F once established, though flower buds may be damaged at temperatures below 20°F. Young plants and those in containers need more protection from freezing conditions.
In regions where temperatures regularly drop below freezing, choose camellia varieties known for their cold tolerance. Consider planting in protected microclimates, such as on the south side of buildings or near other structures that provide wind protection. The plants appreciate high humidity but can adapt to lower humidity levels if soil moisture remains adequate.
Fertilizing Your Camellias
Feed your camellias three times during the growing season using a fertilizer formulated for acid-loving plants. Apply fertilizer in early spring as new growth begins, again in late spring after the first flush of growth, and a final time in early summer. Avoid fertilizing after mid-summer, as this can encourage tender new growth that may be damaged by early frosts.
Use a balanced fertilizer designed for azaleas and camellias, which typically has a formulation like 10-10-10 or similar. Follow package directions carefully, as over-fertilizing can cause leaf burn and actually reduce flowering. If your soil is already rich in organic matter, you may need to reduce fertilizer amounts accordingly.
Pruning and maintenance
One of camellias’ greatest appeals is their low-maintenance nature. Healthy plants require minimal pruning—mainly just removing dead or damaged branches and shaping the plant if desired. The key is timing: prune immediately after flowers fade, which allows the plant time to develop new growth that will produce next season’s flower buds.
If you prune too late in the season, you’ll remove the buds that create the winter and spring blooms. When pruning, use clean, sharp tools and make cuts just above a leaf node or branch junction. Remove any crossing branches or those that rub against each other to maintain good air circulation within the plant.
Growing Camellias in Containers
Container growing is an excellent option for gardeners with challenging soil conditions or limited space. Choose a large, wide container with adequate drainage holes—camellias absolutely cannot tolerate sitting in water. Use a quality potting mix formulated for acid-loving plants, or create your own blend of peat moss, pine bark, and perlite.
Container-grown camellias need more frequent watering than those in the ground, as pots dry out faster. They also require regular fertilization since nutrients wash through the container more quickly. Plan to repot every three years or so, pruning the roots slightly and moving to a larger container with fresh potting mix as needed.
Common pests and diseases
Healthy camellias are generally resistant to problems, but stressed or neglected plants can fall victim to various pests and diseases. Watch for common insect pests including aphids, thrips, mealybugs, scale insects, and spider mites. These are best controlled with horticultural oils like neem oil, which smother pests without harming beneficial insects.
Fungal diseases can include leaf spots, petal blight, canker, anthracnose, and root rot. Petal blight is particularly frustrating, causing flowers to shrivel just as they begin opening. Early fungicide applications can help prevent problems, but once disease appears, affected plant parts should be removed and destroyed to prevent spread.
Troubleshooting Common Problems
Yellow Leaves with Green Veins
This symptom indicates chlorosis, caused by soil that’s too alkaline. Camellias need acidic soil to properly absorb nutrients, particularly iron. Lower your soil pH by amending with agricultural sulfur or using acidifying fertilizers designed for azaleas and camellias. This condition is reversible if caught early.
Yellowing Leaves and Wilting
These signs often indicate root rot, which can kill plants quickly or slowly over several years. There’s no cure for fungal root rot; affected plants must be removed to prevent disease spread. Before replanting, improve soil drainage by adding plenty of organic matter to increase porosity.
Burned Leaf Edges
Leaf edge burn typically results from over-fertilization. Skip the next scheduled feeding and reduce fertilizer amounts in the future. Sometimes, this can also indicate salt buildup in container-grown plants, which may require flushing the soil with water.
Encouraging Beautiful Blooms
Camellias bloom from late fall through early spring, depending on the variety. To maximize flowering, ensure your plants receive adequate nutrition, proper watering, and appropriate light levels. Avoid pruning at the wrong time, protect developing flower buds from frost damage, and maintain slightly acidic soil conditions.
If your camellia isn’t blooming as expected, check these common causes:
- Improper pruning timing – Pruning too late removes flower buds
- Cold damage – Unseasonable frosts can kill developing buds
- Nutrition issues – Both too little and too much fertilizer can affect flowering
- Soil pH problems – Alkaline soil prevents proper nutrient uptake
- Insufficient light – While they prefer shade, too much darkness reduces blooms
- Drought stress – Inadequate water during bud development reduces flowering
Long-Term Success and Enjoyment
With proper care, camellias become increasingly beautiful and valuable over time. These are truly plants that grow better with age, and there are documented cases of camellias living for more than 500 years. Many century-old plants are still thriving in gardens today, making camellias excellent investments for your landscape.
Whether you’re planting a single specimen as a focal point, creating a hedge or border, or incorporating camellias into a mixed shrub planting, these plants will reward you with years of stunning winter blooms. Their glossy evergreen foliage provides year-round interest, and their flowers bring color and elegance to gardens when most other plants are dormant.
Final Thoughts
Camellias offer gardeners in suitable climates an opportunity to grow something truly special—plants that combine year-round beauty with spectacular seasonal flowers. By understanding their needs for acidic soil, consistent moisture, and filtered light, you can enjoy these elegant shrubs for many years to come. With their slow growth and exceptional longevity, camellias are plants that become part of your garden’s legacy, providing beauty for generations.
