How often to water leatherleaf viburnum in California
In July in the Central Valley, established leatherleaf viburnum 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. Leatherleaf viburnum is an evergreen shrub from China with long, wrinkled, dark green leaves that are fuzzy on both sides. Flat clusters of yellowish white flowers open in late spring from buds formed the previous summer and fall, and bright red berries can last into winter. It likes average to moist, acidic, well-drained soil and shelter from winter winds.
How often to water leatherleaf viburnum, month by month
Type your city above and the days between waterings and the gallons appear here, worked out from your city's climate table. Or read the figures by climate zone further down.
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.
How to tell it needs water
- Push a finger beside the stems: dry soil past the second knuckle in summer means leatherleaf viburnum wants water
- Big leaves drooping and curling in afternoon heat suggest thirst
- Leaf margins browning after a hot, windy spell can follow dry soil
- Yellowing between the veins in alkaline soil points to soil chemistry, not water
How to water it
- Water deeply at the root zone with drip or a soaker
- Let the upper few inches dry before watering again
- Plant in average to moist, acidic, well-drained soil
- Shelter it from cold, drying winter winds
- Keep watering through late summer, when next year's buds form
Through the seasons
Give a new shrub steady water through its first summer. Established plants want moderate, deep watering in the dry months, including late summer, when flower buds form for next spring. It stays evergreen, blooms in late spring and holds red berries into winter. On the north-central coast, in the Central Valley, on the south coast and in South Inland, WUCOLS gives leatherleaf viburnum a moderate water rating. The high desert and the low desert have no WUCOLS evaluation for it.
In pots
Leatherleaf viburnum can grow in a large container for some years if the pot is wide and heavy. Use an acidic, well-drained mix. When the upper couple of inches feel dry, soak until water runs out the base. In summer, check pots every few days, since the big leaves use water fast. Do not leave water in the saucer. In winter, water when the mix dries and rain falls short.

How this is worked out: the WUCOLS water rating for each zone times that zone’s climate for the month. A dash means WUCOLS does not rate the plant there. The figures are what the plant uses, before sprinkler losses.

Questions people ask
How often should I water leatherleaf viburnum in summer?
In July, established leatherleaf viburnum 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 leatherleaf viburnum need per day?
In July in the Central Valley, established leatherleaf viburnum 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 leatherleaf viburnum change across California?
Yes. WUCOLS rates leatherleaf viburnum 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 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.
When does leatherleaf viburnum bloom?
It blooms in late spring. The flower buds form the summer and fall before and are ornamental all winter. Do not prune them off.
Does leatherleaf viburnum have berries?
Yes, bright red berries follow the flowers and can last into winter. They add color in the cool months. Leave them on the shrub.
What soil does leatherleaf viburnum need?
It prefers average to moist, acidic, well-drained soil. Alkaline soil may cause yellow leaves. Add acid mulch.
Is leatherleaf viburnum good for hedges?
Yes, it works in mixed shrub borders and as a hedge. Its large leaves give a bold look. Space plants to allow air flow.
Why did my leatherleaf viburnum lose leaves in winter?
Cold winter wind can cause dieback. Plant it where it is sheltered. Prune damaged growth in spring.
