How often to water pagoda dogwood in California
In July on the north-central coast, established pagoda dogwood in loam needs a deep watering about every 13 days: about 55 gallons each time under a 10 foot canopy, about 29 gallons a week. Pagoda dogwood is a deciduous small tree or large shrub from eastern North America, named for its flat, tiered branches. It grows 15 to 25 feet tall and often wider than tall. Its fibrous roots spread shallow and do best kept cool and moist. It prefers cool summers, so steady water and afternoon shade matter in warmer gardens.
How often to water pagoda dogwood, 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 under the branches, and skip a watering after a good soaking rain.
How to tell it needs water
- Soil dry 3 inches down under the canopy means pagoda dogwood needs water, since its shallow roots want steady moisture
- Leaves that droop or curl on hot afternoons over dry soil can point to a thirsty root zone
- Leaves wilting and yellowing while the soil stays wet can point to root rot, a known problem for this dogwood
- Dead patches of bark on the sunny side of the trunk can be sunscald, which watering will not fix
- Branches dying back with sunken areas of bark are more likely canker than thirst
How to water it
- Spread water across the whole area under the canopy with drip line or a soaker ring, since the fibrous roots run wide and shallow
- Soak the soil about 12 inches deep, then water again once the top 2 inches dry
- Keep a wide layer of wood chip mulch over the root zone to hold it cool and moist, pulled a few inches back from the trunk
- Plant in acidic, rich, well-drained soil where the tree gets shade in the afternoon
- Move the watered ring outward as the tiered branches spread wider each year
Through the seasons
Water a new pagoda dogwood deeply through its first two summers while its shallow roots spread. Established trees still need consistent moisture, since they do best where summers are cool. Fragrant creamy-white flowers open in late spring. Bluish-black fruit on red stalks follows in summer, and the leaves turn reddish-purple in fall before dropping. The bare tree rests through winter, when rain covers the cool months on the north-central coast. WUCOLS rates pagoda dogwood moderate water on the north-central coast. WUCOLS has not evaluated it for the Central Valley or the south coast. WUCOLS marks it as not suited to South Inland, the high desert or the low desert.
In pots
Pagoda dogwood is a tree for the ground, and its shallow roots make it a poor candidate for moving later. Keep a nursery plant in its container only until it is planted. Check the mix 2 inches down every few days, and daily in summer heat. Water until it runs from the drainage holes, then empty the saucer. Shade the container itself, since a sunny pot heats the roots this tree wants kept cool. In winter the leafless plant uses little water, so let the mix dry slightly between soakings.

Questions people ask
How much water does pagoda dogwood need per day?
In July on the north-central coast, established pagoda dogwood needs about 4.1 gallons a day under a 10 foot canopy and about 16 gallons a day under a 20 foot canopy. Give it in deep waterings spread days apart rather than a little every day, so the whole root zone gets wet.
Does watering for pagoda dogwood change across California?
Yes. WUCOLS rates pagoda dogwood separately for each of the six California climate zones: moderate water in the North-Central Coastal zone, not evaluated in the Central Valley zone, not evaluated in the South Coastal zone, not suited to this region in the South Inland zone, not suited to this region in the High and Intermediate Desert zone, not suited to this region in the Low Desert zone. The monthly table above shows how the same rating translates into different gallon amounts as reference evapotranspiration changes.
Can pagoda dogwood handle hot summers?
It performs best in cool summer climates and appreciates afternoon shade where summers run hot. In California, WUCOLS rates it only for the north-central coast. Mulch and consistent moisture help keep its root zone cool.
Why is it called pagoda dogwood?
The name comes from its horizontal, tiered branches, which turn up at the tips like a pagoda roof. It is also called alternate-leaf dogwood, because its leaves alternate along the stem. Most other dogwoods have opposite leaves.
Can I move a pagoda dogwood?
It does not transplant well because of its shallow root system. Choose its permanent spot before planting. If a move cannot be avoided, keep the new root zone moist and mulched afterward.
Is pagoda dogwood salt tolerant?
No, it does not tolerate salt. Plant it away from ocean spray, and avoid spots where salty runoff collects.
Do birds eat pagoda dogwood fruit?
Yes. Birds and small mammals are drawn to the bluish-black fruit, which ripens in summer. The flowers also feed butterflies and other pollinators.
What pests and diseases affect pagoda dogwood?
Scale, leaf miners and borers turn up at times. Leaf spot, twig blight, canker and root rot are the diseases to watch. Avoid soggy soil, which favors root rot.
