How often to water Texas sage in California

In July in the Central Valley, established Texas sage 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. This Texas sage is Salvia coccinea, also called scarlet sage, a perennial native to the southeastern United States and tropical America. It grows 1 to 3 feet tall with loose whorls of inch-long, bright red tubular flowers that draw hummingbirds and butterflies. It is short-lived, reseeds easily, and can bloom much of the year where winters are mild.

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

  • Soil dry 3 inches down beside the plant in summer means Texas sage can take water
  • Flowering slowing during a dry spell suggests the plant wants a drink
  • Leaves wilting in afternoon heat can point to a dry root zone
  • Plants dying out after a few years is normal for this short-lived sage, not a water problem

How to water it

  • Water deeply during dry spells, then let the soil dry between soakings
  • Wet the root zone about 6 to 8 inches deep
  • Plant in full sun to part shade in sandy, fertile soil
  • Use clay soil only where it drains well
  • Pull unwanted seedlings while they are small

Through the seasons

Water new plants regularly until they settle. Established plants tolerate drought but flower more freely with water during dry spells. Bloom runs from early summer until frost, and longer where winters stay mild. Plants are often short-lived but replace themselves from seed. WUCOLS rates Texas sage low water on the north-central coast. In the Central Valley, on the south coast, in South Inland and in both deserts it carries a moderate water rating.

In pots

Texas sage does well in a pot on a sunny patio, where hummingbirds can find it. Use a well-drained mix. Water when the top couple of inches are dry, until water runs out the bottom. In summer, a pot may need water every day or two. Empty the saucer so the roots never sit wet. Seedlings may pop up in nearby pots, so pull extras. In winter, water only when the mix dries.

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 Texas sage. Plants that drink alike can share one valve and one schedule.

Similar plants that need less water 16

Rated lower than Texas sage in the Central Valley. Worth a look for a new bed or a lawn replacement.

Questions people ask

How often should I water Texas sage in summer?

In July, established Texas sage in loam needs a deep watering about every 5 days in the Central Valley, about every 7 days on the south coast and about every 6 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 Texas sage need per day?

In July in the Central Valley, established Texas sage 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 Texas sage change across California?

Yes. WUCOLS rates Texas sage separately for each of the six California climate zones: low 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, moderate water in the High and Intermediate Desert zone, moderate water in the Low Desert zone. The monthly table above shows how the same rating translates into different gallon amounts as reference evapotranspiration changes.

Is this the same as the shrub called Texas sage?

No, this is Salvia coccinea, a red-flowered perennial sage. Other plants share the name Texas sage. Check the botanical name on the label.

Does Texas sage reseed?

Yes, it reseeds easily and can turn weedy. Pull seedlings you do not want. Deadhead to reduce seed.

Does Texas sage attract hummingbirds?

Yes, its red tubular flowers attract hummingbirds and butterflies. It blooms over a long season. Water in dry spells for more flowers.

Is Texas sage perennial?

It is perennial in warm climates and acts as an annual where winters freeze. It may be short-lived either way. Seedlings often replace old plants.

Can Texas sage grow in clay?

It tolerates clay if drainage is good. Sandy, fertile soil suits it best. Avoid spots where water stands.
