What Soil pH Do Camellias Prefer?

Camellias grow best in slightly acidic soil with a pH between 5.0-6.5. This mildly acidic pH range allows camellias to access nutrients like iron, manganese, zinc, copper, and boron. Soil that is too alkaline above a pH of 7.0 can limit the availability of these key nutrients resulting in yellowed foliage and lackluster growth.

According to research by Clemson University, iron deficiency is the most common nutritional problem with camellias.^1^ The ideal soil pH keeps iron soluble and accessible. Regularly testing the soil pH with a kit allows monitoring to keep the acidity in the target range.

Should the Soil Be Moist or Dry for Camellias?

Camellias require consistently moist, well-drained soil. Their fibrous roots are very sensitive to drought stress. Allowing the soil to completely dry out can quickly damage the root system. This leads to leaf drop, bud drop before flowering, and decline.

Ideally, the soil should be kept evenly moist to a depth of 12-18 inches for mature camellias. Watering when the top few inches become dry provides moisture while preventing waterlogged conditions at depth. Drip irrigation, soaker hoses and mulching helps maintain consistent moisture.

What Type of Soil Drainage is Best for Camellias?

Excellent drainage is imperative to avoid root rot and other problems. Camellias will not tolerate heavy, dense, soggy soil with poor aeration. Stagnant water around the roots creates an oxygen deficiency. It also allows fungal pathogens to proliferate that cause rot.

Well-drained sandy loam, loam, or clay soils are suitable. Good internal air circulation is needed for gas exchange between the roots and soil. Raised garden beds can improve drainage. If the natural drainage is poor, planting camellias on a slope aids drainage.

Should Camellia Soil Be High in Organic Matter?

Yes, camellias thrive in soil abundant in organic matter such as compost, leaf mold, or aged pine bark. Organic materials retain moisture, maintain an acidic pH, support beneficial microbes, and provide nutrients.

Incorporating 2-4 inches of organic amendments when preparing the soil creates an ideal growing environment. Ongoing additions of 1-2 inches per year will replenish organic matter as it decomposes.

According to the American Camellia Society, an organic layer on the soil surface through mulching is extremely beneficial as well.^2^ Mulch insulates the roots, suppresses weeds, and as it decomposesreleases nutrients.

What Soil Types Can Camellias Grow In?

Camellias are adaptable and can grow in a range of soil types including:

  • Clay soil – Camellias tolerate clay soil provided it has sufficient drainage. Working in ample organic matter lightens heavy clay.
  • Sandy soil – Sandy soils drain freely but dry out rapidly. Adding organic matter enhances moisture retention in sand.
  • Loam soil – Loamy soils with a blend of sand, silt, and clay provide an ideal balance of drainage and moisture for camellias.
  • Chalk soil – Alkaline chalk soils will need acidifying amendments to lower the pH for camellias.

Is it Okay to Grow Camellias in Waterlogged Soil?

No, camellias should never be grown in soils that are waterlogged or have poor drainage. Standing water around the roots quickly leads to root rot and the decline of the plant. Camellias need soil oxygen levels above 10% to thrive.^3^

Soggy soil prevents air penetration into the root zone. It also allows fungal pathogens like Phytophthora cinnamomi to proliferate, causing severe root rot with no cure.

What to Do If the Garden Soil is Unsuitable for Camellias?

When the native soil is too alkaline, dense, or poorly draining, camellias can be successfully grown in containers or raised beds using a quality potting mix amended with organic materials.

An ericaceous compost or potting soil specifically formulated for acid-loving plants provides the ideal growing medium. Mix in leaf mold or pine bark to enhance drainage and aeration. Container culture prevents problem soils from negatively impacting camellia health.

How Can I Improve My Soil to Grow Camellias?

Here are some tips for modifying marginal garden soil to meet the needs of camellias:

  • Test the soil pH and lower as needed through application of elemental sulfur.
  • Dig in 2-4 inches of organic matter such as compost, peat moss, rotted oak leaves, or pine bark to improve texture, moisture holding capacity, and nutrition.
  • To promote drainage, mix in builder’s sand or perlite. Raised beds also improve drainage.
  • If the soil is dense, subsoiling or double digging can help open it up for better root penetration.
  • Ongoing mulching maintains organic matter and soil health.

What is the Best Way to Prepare Soil When Planting Camellias?

When planting a new camellia, properly preparing the soil ensures the plant establishes well. Follow these tips from the American Camellia Society for planting success:^4^

  • Dig a planting hole at least 2 feet wider than the container or root ball.
  • Leave the soil in the center undisturbed to prevent settling.
  • Build a raised mound of soil in the center to provide good drainage.
  • Set the root ball on the mound so the top is slightly above the surrounding soil level.
  • Backfill around the ball with native soil, compost, and any other amendments.
  • Water thoroughly to eliminate air pockets and settle the soil.
  • Apply 2-4 inches of organic mulch over the soil surface.


In summary, camellias require consistently moist yet well-drained acidic soil with abundant organic matter. A mildly acidic pH of 5.0-6.5 provides ideal conditions. Camellias can adapt to various soil types like clay, loam, or sand provided excess moisture does not accumulate. Poor drainage resulting in waterlogged soil is detrimental and must be avoided. Amending native soil with organic matter, lowering pH, and employing container culture enables growing lush, flowering camellias even in problem soils. With the proper soil preparation and care, camellias will flourish and enhance the garden with their spectacular blooms.

Frequently Asked Questions

What causes yellow leaves on camellias?

The most common cause of yellowing camellia foliage is iron deficiency induced by incorrect soil pH. Check that the soil pH is between 5.0-6.5. If too alkaline, lower the pH through application of elemental sulfur and chelated iron.

How often should camellias be watered?

Water camellias when the top few inches of soil begin to dry out. Established plants need about 1-2 inches of water per week from rain or irrigation. Allow the soil to dry slightly between watering to prevent rot.

Can I grow camellias in pots?

Yes, camellias adapt very well to container culture. Use a quality potting mix amended with extra peat moss or pine bark to maintain acidity. Check soil moisture frequently and water when the surface just begins to dry.

When is the best time to plant camellias?

Early spring is ideal for planting container-grown camellias. This gives the roots time to establish before the heat of summer. Fall is suitable for transplanting established camellias. Avoid planting in summer or winter.

How close can camellias be planted to each other?

Space camellias 3-6 feet apart depending on mature size. Dwarf varieties under 3 feet tall can be spaced 2-3 feet while large camellias may need 6 feet or more between plants.

Should camellias be fertilized?

Apply an acidic fertilizer formulated for camellias in early spring. Use half strength the first year after planting. Mature plants benefit from a second application in midsummer. Avoid over-fertilization which can damage roots.

Can I grow camellias in zones colder than zone 7?

Choose cold-hardy camellia varieties like the sasanqua and hiemalis types for colder zones. Provide winter protection with mulching. Avoid planting in open, windy sites. Grow in protected microclimates against structures or use cold frames.

How do I revive an ailing camellia plant?

First ensure adequate moisture and correct any drainage issues. Apply chelated iron if leaves are pale. Prune out dead branches. Use a systemic fungicide on root rot. Protect damaged roots by mounding organic mulch. Fertilize lightly in spring with an acid fertilizer. New growth indicates recovery.

Are camellias deer resistant?

Deer tend to avoid camellias due to their thick, leathery foliage. They also dislike the acidic conditions preferred by camellias. Planting alongside other deer-resistant plants provides additional protection. Deer may sample flowers but typically do not heavily damage mature plants.

In summary, camellias thrive best in moist, well-drained, slightly acidic soil abundant in organic matter. Avoid extremes of poor drainage or drought. Test soil pH periodically and amend as needed to maintain acidity. Improve marginal garden soils through adding organic material and employing proper planting techniques. With the preferred soil conditions, camellias will flourish, growing lush foliage and producing their stunning signature blooms.
