How often to water Little Ragu dwarf bay in California
In July in the Central Valley, established Little Ragu dwarf bay in loam needs a deep watering about every 20 days: about 8.8 gallons each time for a plant 4 feet across, about 3.0 gallons a week. Little Ragu is a dwarf sweet bay, an evergreen shrub that tops out around 6 to 8 feet each way. Its deep olive-green leaves are aromatic and can be used in cooking like any bay, and small yellow flowers appear in spring. Sweet bay comes from the Mediterranean, and its roots dislike soil that stays wet.
How often to water Little Ragu dwarf bay, 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 still moist a few inches down means Little Ragu dwarf bay does not need water yet
- Leaves dulling and drooping after a long dry spell in summer heat can signal thirst
- Yellowing leaves and dieback in soil that stays wet point to root rot
- Sticky leaves or small bumps on stems point to scale or psyllids, not water
How to water it
- Water deeply, then let the soil dry several inches down before the next soak
- Plant in sun or light shade in well-drained soil
- Accept heavy soil only where it drains
- Shear it lightly as a low hedge or leave it natural
- Harvest leaves for the kitchen as needed
Through the seasons
Water a new plant regularly through its first summer while roots spread. Once established, let the soil dry down several inches between waterings to avoid root fungal diseases. It stays evergreen all year and blooms in spring. Near the coast it handles more sun, while inland it does best with some light shade. WUCOLS rates Little Ragu dwarf bay low water in the Central Valley and on the south coast. WUCOLS has not evaluated it for the north-central coast, South Inland, the high desert or the low desert.
In pots
Little Ragu dwarf bay suits a large container near the kitchen door. Use a well-drained mix. Water when the mix is dry a few inches down, until it runs from the base. In summer, check every few days. Never let the pot sit in water, since soggy roots invite fungal rot. Trim it to keep a tidy shape. In winter, rain may cover it, so check before watering.

Questions people ask
How often should I water Little Ragu dwarf bay in summer?
In July, established Little Ragu dwarf bay in loam needs a deep watering about every 20 days in the Central Valley and about every 27 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 Little Ragu dwarf bay need per day?
In July in the Central Valley, established Little Ragu dwarf bay needs about 0.4 gallons a day for a plant 4 feet across and about 1.7 gallons a day for a plant 8 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 Little Ragu dwarf bay change across California?
Yes. WUCOLS rates Little Ragu dwarf bay separately for each of the six California climate zones: not evaluated in the North-Central Coastal zone, low water in the Central Valley zone, low 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.
Can I cook with Little Ragu leaves?
Yes, it is a sweet bay, and its aromatic leaves are used in cooking. Pick mature leaves. Dry them for storage.
How big does Little Ragu dwarf bay get?
It reaches about 6 to 8 feet tall and wide. That is much smaller than a standard sweet bay. It suits small gardens.
Why are my bay leaves yellowing?
Wet soil can cause root rot in sweet bay. Let the soil dry several inches between waterings. Check that the site drains.
What pests bother sweet bay?
Scale and psyllids are occasional pests. Check new growth and stems. Root rot is the main water-related problem.
Can Little Ragu grow in shade?
Sweet bay grows in sun or shade. Cool coastal sun or light shade inland suits it best. Shade slows drying, so water less there.
