How often to water basket plant in California
In July on the south coast, established basket plant in loam needs a deep watering about every 7 days: about 1.5 gallons each time for a plant 2 feet across, about 1.4 gallons a week. Basket plant is a tropical evergreen perennial from Mexico, with waxy leaves packed into rosette-like clusters and trailing stems that root wherever they touch moist soil. It works as a groundcover in mild gardens and spills from hanging baskets. It wants regular water in soil that drains well, in part sun or light shade.
How often to water basket plant, 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 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.
How to tell it needs water
- Soil dry an inch or two down between the rosettes means a groundcover patch is ready for a soak
- Leaves that fade and wilt in afternoon heat over dry soil point to thirst
- Leaf tips and edges dying back can follow a dry spell, though frost and salt cause the same look
- Wilting while the soil stays soggy for days points to overwatering or poor drainage, which kills roots
- Purple-tinged leaves lying flat reflect bright light rather than a water problem, while upright green growth reflects shade
How to water it
- Water the soil between the rosettes with drip line or a gentle hose
- Moisten the root zone several inches deep, then let the top inch dry before watering again
- Plant in well-drained soil, and use a raised bed or mound where clay holds water
- Site it in part sun or light shade, where the soil stays moist longer than in full sun
- Extend drip lines as rooted stems widen the patch, and cut back stems that creep into other beds
Through the seasons
Keep a new planting evenly moist until its stems begin to root and spread. Established patches still need regular water, as this tropical plant grows best in moist, well-drained soil. It stays evergreen, and when it blooms, small fragrant white flowers rise on tall spikes. Frost is the main winter risk: it is hardy only to about 30 degrees F, though it handles a mild frost in coastal California. Winter rain covers the cool months on the south coast, where WUCOLS rates it moderate water. WUCOLS has not evaluated it for the north-central coast, the Central Valley, South Inland, the high desert or the low desert.
In pots
Basket plant suits a hanging basket, where its trailing stems spill over the rim. Baskets dry fast in warm, breezy air, so check the mix an inch down every day or two in summer heat. Water slowly until it drains from the bottom, then let the basket finish dripping before you hang it back up. Empty the saucer under a floor pot after each soak. It takes only a mild frost, so move pots under cover before freezing nights, and let the mix dry a little more between soakings in the cool months.

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 much water does basket plant need per day?
In July on the south coast, established basket plant needs about 0.2 gallons a day for a plant 2 feet across and about 0.8 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 basket plant change across California?
Yes. WUCOLS rates basket plant separately for each of the six California climate zones: not evaluated in the North-Central Coastal zone, not evaluated 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.
Is basket plant invasive?
It has naturalized in many subtropical areas, where it is treated as a garden weed. Its stems root wherever they touch moist soil, which is how a patch creeps outward. Trim the edges of the patch and keep it out of wild areas.
Why is my basket plant tall and green instead of purple?
Light sets its shape and color. In bright light it lies flat and the leaves take on a purple tint, while in deeper shade it grows upright and looks like a small dracaena. Changing the watering will not change that.
Can basket plant survive frost?
Only a mild one. It is hardy to about 30 degrees F and can come through the cooler winters of coastal California. In colder spots, grow it in a pot that can move under cover.
Does basket plant flower?
Yes. Small white flowers open in clusters on spikes about 2 feet tall. They are fragrant, and the species name refers to that scent.
Can I start new basket plants from the stems?
Yes. Its stems root where they touch moist soil, so a stem pinned onto a pot of damp mix can make a new plant. Keep that mix moist until new growth shows, then cut the stem free.
