How often to water common witch hazel in California

In July in the Central Valley, established common witch hazel 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. Common witch hazel is a deciduous shrub or small tree from woodland edges and stream banks of eastern North America. In fall its leaves turn golden yellow, and fragrant yellow flowers with crinkled, strap-like petals open along the branches from about October into December. It needs moist, acidic, humus-rich soil and does not tolerate drought.

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

  • Leaves wilting or scorching at the edges in a dry spell show stress, since this shrub does not tolerate drought
  • Soil dry 2 inches down under the branches in summer means it is time for a deep watering
  • Yellowing leaves and dieback in soil that stays waterlogged can point to Phytophthora root rot
  • Few flowers on a shrub in deep shade reflect too little sun, since bloom is best in full sun
  • Small bumps or galls on the leaves come from tiny insects and do not harm the plant

How to water it

  • Water at the base with a soaker or drip, wetting the soil about a foot deep
  • Keep the soil moist through summer, watering again before the top couple of inches dry out
  • Plant in full sun or part shade in acidic, humus-rich soil that drains well, sheltered from cold drying winds
  • Spread mulch over the root zone to conserve moisture
  • Widen the watered area as the shrub spreads

Through the seasons

Keep a young shrub evenly moist through its first summers. It leafs out in spring, needs steady moisture through the dry season, and turns golden yellow in fall. Flowers open from about October into December, sometimes while seed capsules from the year before are still on the branches. Prune, if needed, in early spring. Winter rain usually covers the bare shrub on the north-central coast and in the Central Valley. WUCOLS rates common witch hazel moderate water on the north-central coast and in the Central Valley. WUCOLS marks it as not suited to the south coast, South Inland, the high desert or the low desert.

In pots

A young witch hazel can live in a large container for a few years before it goes in the ground. Use an acidic, humus-rich mix that holds moisture yet drains, in a pot with drainage holes. In summer, check the mix every day or two and water before the top inch dries out. Let water drain through, then empty the saucer. Keep the pot in part shade during hot spells, and water lightly in winter.

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.

Plants with the same water needs 16

Rated moderate water in the Central Valley, like common witch hazel. Plants that drink alike can share one valve and one schedule.

Similar plants that need less water 16

Rated lower than common witch hazel in the Central Valley. Worth a look for a new bed or a lawn replacement.

Questions people ask

How much water does common witch hazel need per day?

In July in the Central Valley, established common witch hazel 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 common witch hazel change across California?

Yes. WUCOLS rates common witch hazel separately for each of the six California climate zones: moderate water in the North-Central Coastal zone, moderate water in the Central Valley zone, not suited to this region 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.

When does common witch hazel bloom?

It flowers in fall, from about October into December, often as the leaves turn yellow and drop. The fragrant yellow flowers have four crinkled, ribbon-like petals.

Can witch hazel handle drought?

No. It is intolerant of drought and needs moist soil through summer. Mulch and deep, regular watering help it through dry spells.

Is this the witch hazel used in skin products?

Yes. Common witch hazel is the species used to make medicinal witch hazel extract.

When should I prune common witch hazel?

Pruning is rarely needed except to shape it. If you prune, do it in early spring, and remember that flowers come on older growth.

Can you overwater common witch hazel?

Yes. It wants moist but well-drained soil, and waterlogged ground can lead to Phytophthora root rot. Water deeply, then let the top inch or two dry.
