I'm trying to gather as many bay laurel nuts as I can find because I love to eat them, but this seems to have been an off year for bay laurel nut production. Is anyone aware of any trees that bore well this year that I might be able to gather from? Are there nuts on the tree, or maybe on the ground now? Thanks!

I have 3 huge multitrunked Umbellularia californica on my lot and one massive single trunked tree that measures over 10' in circumfrance and is over 110' tall. These are all part of a very unique native plant community that blankets canyons and creeks in the East Bay foothills. In many areas there are acres and acres of unbroken evergreen cover made up of this species and Quercus Agrifolia - the Coast Live Oak. Umbellularia is messy - big leaf drops, messy olive like fruits, and a tendancy to collect dust and pollution on the sticky leaves turning them black. The smells are extraordinary and the wildlife habitat they create are supurb. I actually pull up at least 30 newly sprouted trees every year from my 1 acre city lot. A keeper.

these are very beautiful trees with a wonderful scent, new foliage in spring opens in a nice red tint. You may want seed from known cold hardy stands if you live in a zone on the edge. This is also fairly easy from seed as long as it is very fresh. once dried out germination drops dramatically.

The oldest California bay in the world is here in Hayward ca. An enormous tree 1,200 years old. I have touched that tree. An awe inspiring monarch.

I love the smell of my baby tree, as well as cooking with the fresh leaves.

There is a large tree in my area with several smaller plants. They make large wide/round evergreen shrubby trees with nice form. Seed drop can be a little messy but easily cleaned. I haven't had much difficulty starting from seed once scarified.

We have many of these trees on our acre in zone 9b and I love them, especially the fact that they are evergreen. Some are very large. I haven't noticed the messy problems noted by a previous writer. We've had to cut two or three down, and from the stumps have come shrubs. There are many babies around, so I'm planning to try to use some as a property border/privacy screen by keeping them pruned.

My Bays are old. I would like to find out just how old.
The circumfrnce is approx 5 feet plus
They are very messy, lots of leaves and a mold, fungus,
that coats everything in the winter. The deck and patio furniture have to be power washed each spring. I respect their age but others in the family grow weary of the mess.
The fragrance is wonderful, and for me offsets any negatives.

My 12 year old bay tree started as a one gallon stick and is now a beautiful 6 foot perfectly shaped, 3 trunk tree. It is growing in a planterbox underneath a mesquite tree so never gets full sun, but dappled sun all day.

Mine has grown from a 6" potted plant, and is now a 6' tree. It is a little leggy, but may have been from being rootbound for a while. Actually, in BR, La, it does better with part shade -- otherwise, dries out too much and leaves get "sunburned" looking.

I do have a neighbor who has had success with air layering his -- took about 3 months for roots to form, but they really took off once the roots started.

This is my favorite tree!

Bay Laurels (also called Mountain Laurels or simply Bay trees) start out as herbs. They grow slowly and can be pruned and used as hedges, but put in the ground and allowed to grow they will become tall trees. To keep them small, simply pot them rather than planting them in your yard. Their fragrant leaves are useful in cooking to flavor foods, but you should NOT eat the actual leaves, which may be too sharp for your throat and can harm your mouth (though they are not dangerous to handle). Their aroma naturally repels bugs such as mosquitos and cockroaches. To bring the bug-repellant properties indoors, add dried Bay leaves to your potpourri. This is simply a beautiful and very useful evergreen.

I live in zone 9a and have a Bay Laurel potted in a large pot on my patio. All it needs is full sun and careful watering (I use a tiny bit of fertilizer with my water because my Bay is in a pot and can't get nutrients from the ground. When watering, put your finget two inches in the soil--if it feels wet, do NOT water it. Otherwise, water sufficiently). This will reward you with new growth in an easy-to-see light green (leaves darken as they mature, as with many plants such as gardenias and English Ivy). Other than watering and occasionally checking for weeds in the soil, Bays are pretty happy if just left in the sun. In the ground, their roots may be close to the top of the soil, so be very careful when planting close to the tree so you don't harm the Bay's roots.

One word of warning: though you may propagate this plant through seeds and cuttings, it is VERY difficult to do so and propagation has a high failure rate. Successful stem cuttings can take up to nine months to begin developing roots. Your best bet is to buy a healthy Bay from a reputable nursery.

This tree's fruit can be eaten when ripe. The seeds can be roasted and eaten as well. It has been used for centuries for its many healing qualities as well as spicing up unique dishes. Walking through these trees in the wild is a must, and camping even better.

Its a big tree...you can use the leaves in cooking to flavor soups and stews but dry the leaves first of it will be to strong.

Neutral mystic On Oct 27, 2002, mystic from Ewing, KY (Zone 6a) wrote:

This is the only species for this genus.The leaves are so aromatic that inhaling their scent may cause a headache. But this herb is traditionally used as a remedy for headaches by infusions or the leaves placed on the forehead. Leaves can also be used as an insect repellent. These trees may require winter protection when young.
