Cleyera japonica, WUCOLS IV

How often to water sakaki in California

In July in the Central Valley, established sakaki 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. Sakaki, also called Japanese cleyera, is a broadleaf evergreen shrub or small tree from Japan that grows 10 to 15 feet tall. New leaves open bronze and turn glossy dark green, and fragrant white flowers in early summer are followed by small berries that ripen dark red. It takes sun or deep shade and is quite drought tolerant 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 to 4 inches down under the shrub in summer signals sakaki needs a soak
  • Glossy leaves dulling and drooping in afternoon heat can indicate thirst
  • Leaves browning at the tips in full afternoon sun can follow dry soil in hot weather
  • Yellowing leaves with soggy soil at the base suggest overwatering
  • Small brown spots on leaves point to leaf spot rather than a water problem

How to water it

  • Run drip lines in a loop under the branch tips
  • Wet the soil a foot deep, and wait for the upper few inches to dry
  • Plant in fertile, well-drained soil, with afternoon shade in hot areas
  • Shelter it from strong winds
  • Mulch under the canopy to keep the soil cool

Through the seasons

Water a new sakaki regularly through its first summer while roots grow out. Once established it is quite drought tolerant, though young plants need regular water. It is evergreen, with bronze new growth in spring and flowers in early summer. Winter rain usually covers the cool months. Three western regions have a WUCOLS rating: the north-central coast, the Central Valley and the south coast all list sakaki as moderate water. South Inland and both deserts have not been evaluated.

In pots

Sakaki makes a handsome container shrub for a shady patio or entry. Use a large pot of well-drained mix and water when the top couple of inches dry, until it drains. In warm weather, check every few days. Empty the saucer each time. Clip lightly to keep its shape. In winter, rain may be enough, so check the mix before watering. Shelter the pot from strong wind, which can topple a tall shrub in a light container.

Questions people ask

How often should I water sakaki in summer?

In July, established sakaki in loam needs a deep watering about every 8 days in the Central Valley and about every 11 days on the south coast. 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 sakaki need per day?

In July in the Central Valley, established sakaki 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 sakaki change across California?

Yes. WUCOLS rates sakaki 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, not evaluated in the South Inland zone, not evaluated in the High and Intermediate Desert zone, not evaluated in the Low Desert zone. The monthly table above shows how the same rating translates into different gallon amounts as reference evapotranspiration changes.

Can sakaki grow in shade?

Yes, it tolerates almost full shade. In hot inland summers, afternoon shade is best. Shade also slows drying.

Can sakaki be used as a hedge?

Yes, it works well as a hedge or foundation planting. Its dense evergreen foliage takes clipping. Water the full hedge line evenly.

Why are sakaki new leaves bronze?

New growth opens bronze and turns dark green as it matures. That is normal. The undersides are yellow-green.

Does sakaki have berries?

Yes, small berries follow the fragrant white flowers and ripen dark red. They last a long time on the plant. Flowers are fragrant.

Is sakaki drought tolerant?

Once established, it is quite drought tolerant. Young plants need regular water. Plant it where strong wind cannot batter it.
