How often to water leopard's bane in California

In July in the Central Valley, established leopard's bane in loam needs a deep watering about every 5 days: about 1.5 gallons each time for a plant 2 feet across, about 1.9 gallons a week. Leopard's bane is a slow-spreading perennial from southeastern Europe, Turkey and the Caucasus. Scalloped, heart-shaped leaves form low clumps, and in mid and late spring, golden-yellow daisies 1 to 2 inches across rise on slender stems. It wants moist but well-drained, reasonably fertile, preferably sandy soil in partial shade.

How this is worked out: established roots fill the top 1 foot 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

  • A clump whose soil crumbles dry an inch or two down in spring is telling you leopard's bane needs water
  • Leaves wilting in afternoon sun can point to a dry root zone
  • Flower stems flopping before the buds open can follow a dry spell
  • Leaf spots or a rotting crown in heavy, wet soil point to too much water

How to water it

  • Water at the base, keeping the soil evenly moist through spring
  • Moisten the soil about 6 inches deep, then let the top inch dry
  • Plant in partial shade in moist but well-drained, sandy soil
  • Deadhead spent flowers for a second flush of bloom
  • Divide crowded clumps in early autumn

Through the seasons

Water new plants regularly while they settle in. Keep the soil evenly moist through spring growth and bloom in mid and late spring, and deadhead for a second flush. It is a deciduous perennial that dies back for winter and spreads slowly by rhizomes. Root rot follows soggy soil, so water less once growth slows. Leopard's bane carries a moderate water rating from WUCOLS in the Central Valley, on the north-central coast and on the south coast. South Inland and the two deserts have no WUCOLS evaluation for it.

In pots

Leopard's bane grows well in a pot in light shade, making a cheerful spring display by a door. Use a reasonably fertile, well-drained mix. Water whenever the surface inch dries, until it drains through. In spring, check pots every few days. Empty the saucer so the crown stays dry. Deadhead for more flowers. After bloom, water only as needed to keep the mix from drying out.

Questions people ask

How often should I water leopard's bane in summer?

In July, established leopard's bane in loam needs a deep watering about every 5 days in the Central Valley and about every 7 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 leopard's bane need per day?

In July in the Central Valley, established leopard's bane needs about 0.3 gallons a day for a plant 2 feet across and about 1.1 gallons a day for a plant 4 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 leopard's bane change across California?

Yes. WUCOLS rates leopard's bane 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.

When does leopard's bane bloom?

It blooms in mid and late spring with golden-yellow daisies. Deadheading can bring a second flush. Water steadily through bloom.

Does leopard's bane need shade?

It grows best in partial shade. Keep the soil moist but well drained. Sandy soil suits it.

How do I divide leopard's bane?

Divide it in early autumn. It spreads slowly by rhizomes. Water divisions well.

What problems affect leopard's bane?

Leaf spot, root rot and powdery mildew may occur. Leaf and bud eelworm can be troublesome. Good drainage helps.

Is leopard's bane good for cutting?

Yes, its daisies make good cut flowers. Cut them as they open. It also suits cottage and wildlife gardens.
