How often to water Etruscan honeysuckle in California
In July on the north-central coast, established Etruscan honeysuckle in loam needs a deep watering about every 13 days: about 2.2 gallons each time for a plant 2 feet across, about 1.1 gallons a week. Etruscan honeysuckle is a vigorous Mediterranean climber, deciduous or semi-evergreen, that twines up to about 13 feet. In early to midsummer it carries fragrant, two-lipped, creamy flowers flushed red that age to yellow, followed by red berries. It grows best in full sun in fertile, moist but well-drained soil.
How often to water Etruscan honeysuckle, 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 the plant covers, and skip a watering after a good soaking rain.
How to tell it needs water
- Ground three inches below the surface gone dry near the main stem in summer tells you Etruscan honeysuckle wants a drink
- Soft new shoots hanging limp through a hot afternoon can mean the roots are short of moisture
- Blossoms browning within a day or two of opening in a heat wave can follow dry soil
- A gray-white dusty film over the leaves is powdery mildew, not a sign of thirst
How to water it
- Run a drip line or slow trickle to the planting spot at the foot of the climber
- Let water sink roughly 8 inches, then allow the upper couple of inches to dry out
- Give it a sunny wall or fence and fertile ground that drains well
- Fix wires or a trellis so the stems can twine upward
- Cut it back right after bloom to keep it within its support
Through the seasons
Give a young Etruscan honeysuckle steady water through its first summer while it climbs. Mature vines like moist, well-drained soil, so give deep soaks through dry summers. It flowers in early to midsummer, then forms red berries. It can lose some or all of its leaves in winter. On the north-central coast, WUCOLS rates Etruscan honeysuckle moderate water. WUCOLS has not evaluated it for the Central Valley, the south coast, South Inland, the high desert or the low desert.
In pots
Etruscan honeysuckle can climb a trellis from a large pot on a sunny patio. Fill the pot with fertile, free-draining mix. Feel the mix with a finger, and once the top two inches are dry, pour slowly until water escapes below. On hot afternoons in July a pot can dry within a few days. Tip out the saucer each time. Prune after flowering, and repot when roots crowd the container. Through winter, water only when the mix has dried.

Questions people ask
How much water does Etruscan honeysuckle need per day?
In July on the north-central coast, established Etruscan honeysuckle needs about 0.2 gallons a day for a plant 2 feet across and about 0.7 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 Etruscan honeysuckle change across California?
Yes. WUCOLS rates Etruscan honeysuckle 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.
Is Etruscan honeysuckle fragrant?
Yes, its creamy, red-flushed flowers are fragrant. They age to yellow. Plant it near a seat or path to enjoy the scent.
When should I prune Etruscan honeysuckle?
Prune right after flowering. Remove tangled or dead stems and shorten long shoots. That keeps it tidy for next year.
What pests bother Etruscan honeysuckle?
Aphids, thrips and whiteflies can attack it, and powdery mildew may appear. Good air flow helps. Water at the base.
Does Etruscan honeysuckle have berries?
Yes, red berries follow the flowers. Do not eat them.
Is Etruscan honeysuckle evergreen?
It is deciduous or semi-evergreen. Expect some leaf drop. New growth returns in spring.
