The larger the container the better for you and your plants because large containers require less frequent watering.
The larger the container, within reason, the better. Container grown plants dry out easily in warm weather and may need watering two or more times a week in very warm weather. A handful of blood, fish and bone fertiliser every month from April to August will provide sufficient nutrients for a healthy plant. An excellent alternative is long-lasting feed for acid loving plants available at large garden centres and diy stores. Normal nitrogen fertilisers should not be used. Camellias in containers will need to be watered with rain water to maintain the acidity of the compost.
We recommend using water from a water butt. Tap water can be used in an emergency and it is better than allowing the plants to dry out.
It is normally caused by scale insects on camellias or less frequently aphids. These secrete a sweet sticky substance as they feed on the leaves. This settles and because it is sugary, it attracts fungi which cause the black sooty material. This is unsightly but rarely causes much damage. The cure, if you have only a small camellia, is to wash it off with the aphids by hand using slightly soapy water - a couple of drops of washing up liquid per pint of water.
Larger plants can can be sprayed with water which will wash off many of the aphids and some of the sooty mould. For more details on aphids see our article here. There is no chemical treatment for this fungal disease however it tends to attack weak plants where there are damp conditions. The best course of action is follows:. Being ericaceous plants, camellias require an acid soil. If your soil isn't acid then consider growing your camellia in a container.
Tap water, especially in hard water districts, often contains too much calcium for camellias, reducing the acidity around the roots over time. Rain water is ideal for watering camellias.
If rain water runs out, tap water is satisfactory for a month or two in summer. Feed camellias in spring and early summer with acidic fertilisers , such as Chempak Ericaceous, Miracle-gro Ericaceous, sulphate of ammonia or sulphate of potash. Controlled release fertiliser pellets are available from Miracid and Phostrogen to mix into the potting compost of container-grown plants, avoiding the need for further feeding until the following season. You can use organic-based fertilisers, including seaweed products and fish, blood and bone.
It should be noted, however, that fish, blood and bone is mildly alkaline because of the calcium in the bone so it would be best not to use where the soil is pH of 7 or above neutral to alkaline as this could encourage deficiencies such as chlorosis. To be clear, though, annual applications are unlikely to cause much problem and, where the pH is increased, the soil could be acidified to compensate for applying this useful fertiliser.
If the weather remains dry directly after applying fertiliser, water to dissolve the fertiliser and avoid damage to the roots.
Camellias make lovely container-grown plants and this is a particularly good method if your garden soil is too alkaline for camellias. Use an ericaceous or multi-purpose potting compost. John Innes ericaceous compost usually gives good results, as its loam content makes it especially easy to manage. RHS research has found that soil-less potting media, including peat-free potting composts , are suitable for camellia growing.
However these composts can lose their structure over time leading to poor drainage and an airless root environment, causing leaves to brown and die back. Re-potting in spring every other year into fresh potting compost is recommended. In the intervening year, replace the top 5cm 2in of compost. Once in the largest pot manageable, consider root pruning. Trim off up to twenty percent of the roots and compost.
Re-pot back into the same container filling the gaps with fresh potting compost. Protect compost from freezing during winter by wrapping pot with fleece or bubble wrap. Fri pm, Rpt Sun pm.

Part shade lovers, camellias are best grown in consistently moist , acidic , organically rich , well-drained soils , similarly to azaleas and rhododendrons.
Apply a root mulch leaves or shredded bark and provide a site sheltered from cold, dry winds as buds and flowers may be damaged by cold winds. Protect from early morning sun and from direct hot summer afternoon sun.
Older camellia plants can thrive in full sun when they are mature enough to have their roots shaded by a dense canopy of leaves. Pruning is rarely needed as most plants develop an attractive shape without pruning. Pick up blooms that drop to the ground to minimize petal blight rust spots on the flowers. Spring planting, rather than fall, is recommended for northern areas because it gives the plant more time to get established before hard freezes.
Watering regularly and deeply is vital in the first summer after planting. Fertilizing is not necessary, but a light application in springtime will increase growth. Excessive or late feeding can lead to bud drop. Some flower bud dropping may be a natural phenomenon as many camellias set more buds than they can open.
Camellias are susceptible to some viruses and fungal diseases including leaf spots, anthracnose, black mold, petal blight, canker and root rot. Watch also for aphids, planthoppers and spider mites. Landscaping with Camellias Highly ornamental, camellias look fabulous in mixed shrub borders where they display their dramatic winter blooms.
They still add beauty to the landscape, even when they are not in bloom. Their handsome evergreen foliage always creates a lovely backdrop for other shrubs and flowers. This helps in presenting a continuously changing scenery during the year. As each new season approaches, new blooms emerge, such as masses of brilliant pink tulips in a pale blue cloud of forget-me-nots for a fresh, new eye-pleasing display. Plant camellias near other acid-loving plants, such as azalea and rhododendron.
Plant at least 5 ft. Camellias are also well-suited flowering shrub for woodland gardens Camellias can be used to create screens and hedges. Plant your camellias 3 ft. Perfect as specimen plants , many Camellia sasanqua are excellent choices for espaliers. Camellias make lovely container-grown plants and this is a particularly great method if your garden soil is too alkaline for camellias.
These common problems can be easily avoided by providing good growing conditions: Water during dry spells in late summer when flower buds are forming Mulch with an in cm layer of chipped bark or leaf mould in late winter or early spring to conserve water around the roots Move container-grown camellias out from under the eaves of the house in late summer or fall so that they catch the rainfall Do not feed camellias later than the end of July, as excessive or late feeding can lead to bud drop Some natural bud drop may occur where too many buds have formed, particularly with double-flowered cultivars.
This should not be excessive and is nothing to worry about Protect tender cultivars with a double layer of horticultural fleece in winter, as low temperatures can lead to bud drop.
