How often to water golden flame honeysuckle in California
In July on the north-central coast, established golden flame 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. Golden flame honeysuckle is a twining vine or sprawling shrub, deciduous or semi-evergreen, that climbs to about 13 feet. Its somewhat fragrant flowers bloom from spring into early summer and suit a pollinator garden. It does best in fertile, moist, well-drained soil in full sun with good air circulation.
How often to water golden flame 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
- Soil dry 3 inches down at the base of the vine in summer signals golden flame honeysuckle needs a soak
- Leaves wilting at the vine tips on hot afternoons can indicate thirst
- White powdery coating on leaves points to powdery mildew, often in still, crowded spots
- Curled new shoots with clusters of small insects point to aphids rather than water
- Yellowing leaves and dieback at the base over soggy soil suggest overwatering
How to water it
- Water the root zone at the base with drip or a slow hose, not over the foliage
- Soak about 8 inches down, then let the top couple of inches dry
- Plant in full sun in fertile, well-drained soil that is not alkaline
- Train it on an open trellis or fence where air moves freely
- Mulch the root zone to keep moisture even
Through the seasons
Water a new vine regularly through its first summer while roots spread. Established plants tolerate some drought. Bloom runs from spring into early summer. It may lose some or all leaves in cold winters. Winter rain usually covers its needs near the coast. WUCOLS rates golden flame honeysuckle moderate water on the north-central coast, on the south coast and in South Inland. WUCOLS has not evaluated it for the Central Valley, the high desert or the low desert.
In pots
Golden flame honeysuckle can grow in a large container with a trellis or obelisk. Use rich, well-drained mix and water when the top inch or two is dry, letting it drain. In summer sun, a pot may need water every couple of days. Empty the saucer each time. Prune after flowering to keep it tidy. In winter, water lightly while growth is slow. Turn the pot now and then so all sides get sun.

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 often should I water golden flame honeysuckle in summer?
In July, established golden flame honeysuckle in loam needs a deep watering about every 11 days on the south coast and about every 9 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 golden flame honeysuckle need per day?
In July on the north-central coast, established golden flame 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 golden flame honeysuckle change across California?
Yes. WUCOLS rates golden flame 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, moderate water in the South Coastal zone, moderate water 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.
Why does my honeysuckle have white powder on the leaves?
That is powdery mildew. Give the vine full sun and better air circulation. Water at the base rather than overhead.
Can golden flame honeysuckle grow in shade?
It grows in shade, but flowering is poorer there. Full sun gives the best bloom. Shade also raises mildew risk.
Is golden flame honeysuckle invasive?
It rarely sets fruit and is not widely reported as invasive. It is listed as invasive in Illinois. It has not been reported as invasive elsewhere.
Can golden flame honeysuckle be a shrub?
Yes, it can be pruned to a 6 foot shrub. As a vine it reaches about 13 feet. Its growth is not dense enough for a full screen.
Does golden flame honeysuckle like alkaline soil?
No, it is intolerant of alkaline soil. Amend with compost or grow it in a pot of acidic mix. Yellowing leaves can signal the problem.
