How often to water seven sons tree in California
In July on the north-central coast, established seven sons tree 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. Seven sons tree is a small tree or large shrub from China, reaching 10 to 20 feet with a narrower spread. In late summer and early fall, clusters of fragrant white flowers cover the canopy and draw bees and monarch butterflies. Afterward, the calyces turn cherry red to rose purple around the seeds, and in winter its peeling gray-brown bark shows a lighter layer beneath.
How often to water seven sons tree, 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
- The soil going dry deep down beneath seven sons tree in summer means it is time for a long drink
- Leaves wilting in afternoon heat point to a dry root zone
- Late summer flower clusters thinning out can follow soil that dried completely
- Peeling bark in winter is a normal feature, not a sign of stress
How to water it
- Water deeply, then let the upper soil dry before the next soak
- Do not let the root zone dry out completely
- Plant in poor to rich soil in sun or light shade
- Choose a single trunk or a fountain-like shrub form by pruning
- Plant it where late-season flowers and winter bark can be seen
Through the seasons
Water a young plant regularly through its first summers while it grows at a moderately fast pace. Established plants want moderate, deep watering and should not dry out completely. Fragrant flowers arrive in late summer, colorful calyces follow into fall, and peeling bark shines in winter. On the north-central coast, WUCOLS rates seven sons tree moderate water. It has not been evaluated by WUCOLS for the Central Valley, the south coast, South Inland, the high desert or the low desert.
In pots
Seven sons tree can grow in a large container while young and moves easily from a pot to the ground later. Use a well-drained mix. Water when the top couple of inches feel dry, until water seeps out. Hot weather calls for a check twice a week, since its leaves lose water quickly. Pour off standing water. In winter, while it is leafless, water only when the mix has dried.

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 much water does seven sons tree need per day?
In July on the north-central coast, established seven sons tree 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 seven sons tree change across California?
Yes. WUCOLS rates seven sons tree 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 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.
When does seven sons tree bloom?
Fragrant white flowers cover the canopy in late summer to early fall. Bees and monarch butterflies visit. Rosy calyces follow.
Why does seven sons tree bark peel?
The gray-brown bark peels back to show a lighter inner layer. It is most visible in winter. It is a feature, not a problem.
Is seven sons tree a tree or a shrub?
It can be either, depending on pruning. It grows 10 to 20 feet tall and half as wide. Train one trunk for a tree form.
Is seven sons tree invasive?
It is not an aggressive self-seeder. It transplants easily from containers. It fits small gardens.
What soil does seven sons tree need?
It grows in soils from poor to rich. It prefers not to dry out completely. Mulch helps.
