Camellia sasanqua (SHADE IN DESERT), WUCOLS IV

How often to water sasanqua camellia in California

In July in the Central Valley, established sasanqua camellia in loam needs a deep watering about every 8 days: about 8.8 gallons each time for a plant 4 feet across, about 7.6 gallons a week. Sasanqua camellia is an evergreen shrub from Japan with glossy, leathery leaves and fragrant flowers up to 3 inches across that open from late fall into winter. It grows fast to 6 to 14 feet and makes a good hedge or screen. It wants well-drained, neutral to acidic soil, shelter from afternoon sun, and it handles drought once established.

How this is worked out: established roots fill the top 1.5 feet of soil, and you water again when that soil has dried halfway. Loam soil holds about 1.5 inches of water per foot. Water the whole area the plant covers, and skip a watering after a good soaking rain.

Which soil do you have?

Dig down a few inches, take a handful of moist soil and squeeze it.

  • Sandy: gritty, falls apart when you open your hand, will not form a ball.
  • Loam: forms a soft ball that crumbles when you poke it.
  • Clay: forms a firm, sticky ball and squeezes out into a ribbon between thumb and finger.

Still not sure? Pick loam. Most garden beds sit between sand and clay.

How to measure plant width

A shrub with its width marked from one side to the other and the circle under it shaded blue

Measure across the plant, from the tips of the leaves on one side to the tips on the other.

Water the whole area the plant covers, shown in blue. The gallons here cover that area.

A wider plant means more gallons each watering, not more waterings. While it is young, measure again each spring.

How to tell it needs water

  • Soil dry 3 inches down under the shrub in late summer signals sasanqua camellia needs water
  • Leaves dulling and drooping in afternoon heat can indicate thirst
  • Leaves yellowing between green veins point to alkaline soil, not thirst
  • Leaf edges browning on the sunny side in hot weather suggest heat stress and too little shade

How to water it

  • Water the root zone with drip or a soaker, keeping flowers dry
  • Soak about a foot down, then let the top few inches dry
  • Plant in well-drained, neutral to acidic soil with afternoon shade
  • Mulch with bark or pine needles to keep roots cool
  • Prune right after bloom, since next year's flowers form on older growth

Through the seasons

Water a new shrub regularly through its first summers. Established plants tolerate dry spells, though deep soaks in long, hot stretches keep them looking their best. It blooms from late fall into winter, when most shrubs are quiet. WUCOLS rates sasanqua camellia moderate water on the north-central coast, in the Central Valley, on the south coast and in South Inland. The low desert also carries a moderate water rating, with a WUCOLS note to give it shade there. WUCOLS marks it as not suited to the high desert.

In pots

A sasanqua camellia can grow in a large container, which makes acid soil easy to provide. Fill the pot with an acidic, well-drained mix. Water when the top inch or two is dry, until it drains from the bottom. In summer, check pots every couple of days, and keep them out of hot afternoon sun. Empty the saucer. Scale insects can build up on potted plants, so check leaf undersides. In winter, water when rain falls short.

Questions people ask

How often should I water sasanqua camellia in summer?

In July, established sasanqua camellia in loam needs a deep watering about every 8 days in the Central Valley, about every 11 days on the south coast and about every 9 days in the South Inland zone. Sandy soil holds less water, so waterings come closer together. Clay stretches them. Check the soil before each watering and skip one after a soaking rain.

How much water does sasanqua camellia need per day?

In July in the Central Valley, established sasanqua camellia needs about 1.1 gallons a day for a plant 4 feet across and about 4.3 gallons a day for a plant 8 feet across. Give it in deep waterings spread days apart rather than a little every day, so the whole root zone gets wet.

Does watering for sasanqua camellia change across California?

Yes. WUCOLS rates sasanqua camellia separately for each of the six California climate zones: moderate water in the North-Central Coastal zone, moderate water in the Central Valley zone, moderate water in the South Coastal zone, moderate water in the South Inland zone, not suited to this region in the High and Intermediate Desert zone, moderate water in the Low Desert zone. The monthly table above shows how the same rating translates into different gallon amounts as reference evapotranspiration changes.

When does sasanqua camellia bloom?

It flowers from late fall into winter, earlier than most camellias. Each plant blooms for four to six weeks. Plant it where winter color is welcome.

When should I prune sasanqua camellia?

Prune soon after it flowers. Next year's blooms form on older growth. It can be trained as a small tree.

Why are my camellia leaves yellow with green veins?

That is chlorosis, often from alkaline soil. Camellias need neutral to acidic soil. Adding iron chelates to the soil can treat it.

Is sasanqua camellia hard to grow in heat?

It appreciates shelter from afternoon sun. In hot inland and desert gardens, plant it in shade. Keep the root zone mulched.

What pests bother sasanqua camellia?

Scale insects are the most troublesome. Aphids and spider mites also appear. Check the undersides of leaves.
