Deciduous Fruit Trees for
Orange County
Before you read further
What is the MINIMUM
CHILL REQUIREMENT?
Many deciduous fruit trees
that evolved in temperate climates require a period of
winter cold in order to produce flowers and fruit. We call
this the minimum chill requirement (MCR). It involves
the number of hours (chill hours) of exposure to
temperatures below 55 degrees F and above 33 degrees F. The
MCR is the minimum number of chill hours (accumulative) that
the tree must be exposed to during the winter season for
proper flower bud development and subsequent fruiting. The
number of chill hours decrease when the tree is exposed to
temperature above 60 degrees F.
Most commercial deciduous
fruit trees require MCRs of between 500 and 800 hours. Our
local areas receive an average of less than 300 hours on
hilltops to 400 hours on the valley floor to more than 600
hours in narrow canyons. The cities of Anaheim, Santa Ana,
Irvine, Costa Mesa, and Huntington Beach are on the flood
plain of Orange County and average 400 hours. Homes near
river beds are even cooler. Hilltop areas of Mission Viejo,
Laguna Niguel, Orange, and Tustin may average less than 300
hours, yet low spots in these same cities may average over
400 hours. Inland canyons and even the steep Laguna Canyon
can average well over 500 hours.
The typical residential yard
has many microclimates. A tree on the exposed south side of
a home may receive only half of the chill hours compared to
a tree on the shaded north side. House walls can leak much
heat to a nearby tree while a moist grass lawn can cool a
tree.
To increase the chill hours
locate a tree just to the north of a wall or evergreen tree
where it will be shaded all winter and still receive
sunlight (for best fruit quality) in summer. White- washing
the trunk and stems will also help.
Cold air has a natural
tendency to flow downhill. It is true that the air is cooler
at higher elevations (1 degree for every 200 feet) due to
reduced atmospheric density, but cold air still flows
downhill. A tree on the crest of a hill may receive only
half the chill hours compared to a tree at the base of a
hill, or especially at the base of a canyon.
Our weather varies greatly.
Our winters are either warmer or cooler than normal. If you
want reliable fruit production then choose a tree with a MCR
that is less than your area averages. If you plant a tree
that has a higher MCR than your area averages, the tree may
produce only sporadically.
Deciduous trees in temperate
climates evolved the MCR in order to avoid leafing out
prematurely during a warm spell in the winter months. As
soon as the MCR is reached the tree will begin growth with
the next warm spell. To be consistently successful in the
benign winter climate of Orange County, a deciduous fruit
tree must have a relatively low MCR (a.k.a. low chill
).
Truthfully, the MCR’s of
fruit trees have not been scientifically determined and
almost all are just educated guesses.
Many deciduous fruit trees
(Apples, Figs, Jujubes, Mulberries) may not have a MCR. We
believe these trees are set to grow when spring days exceed
a certain temperature.
When we list the MCR as
300-500 (for example) we are giving the range of MCR’s
listed for that variety from various references. If the # is
followed by a (?), this means that the MCR listed is our own
estimate.
CONTROLLING PRODUCTION
Most full grown fruit trees
can produce 200-300 fruit at harvest time which typically
lasts 2-4 weeks. Few families can eat fruit that quickly.
There are several strategies to make production practical.
Control size with summer
pruning. We prefer to keep each tree about 7 feet tall and 4
feet wide. Since fruit does not grow on new growth (jujube
and fig are exceptions) this growth can be cut off all
summer without affecting next year’s crop. A tree this
size will produce 50-70 fruit.
Control size by grouping
varieties. If 2-5 varieties of apples are planted within 2
feet of each other, this group is not capable of growing
significantly larger than a single tree. This group will
still produce 200-300 fruit, but now has 2-5 different
ripening periods. Much more of the fruit can be consumed.
Both methods can be
incorporated. In my own garden we have 8 apple varieties
planted in 2 groups, each group allowed to grow only 8 feet
tall and 4 feet wide. We can pick apples nearly any day from
mid-summer to early winter.
Fruit trees can also be
planted 3-4 feet apart and maintained as a hedge.
Consult the handout What
is Backyard Orchard Culture? for details.
Generally, we do not
recommend genetic dwarf fruit trees. Of the few available
varieties none are superior quality fruit.
APPLES
are a
reliable crop in our area. It has become apparent that most
(perhaps all) apples do not have a MCR. Most apples bloom in
April. A few bloom in February. Most apples are at least
partially self-fertile, however, most produce a better crop
if they are pollinated by a different variety with the same
bloom period. A few (see text) require a pollinator. Too
create a stronger bloom, strip off all of the leaves grown
the previous year by March. Occasionally we’ll have a
winter cool enough to cause all the foliage to drop. Apples
begin production as early as the second year, but some may
require four years. Apples require thinning after fruit set
to 1 per cluster or less. We offer semi-dwarf trees (M111
rootstock) which can grow trees 15-20 feet tall, but can be
maintained as low as 4 feet tall. Apples can be espaliered
along a fence. Apple trees prefer ample water and love lawn
conditions.
Apples have some pests.
Fireblight (worst on Gala) can be controlled by
application of copper sulfate just before bloom. Codling
moth (apple worms) can be lessened by proper thinning and
choosing early or late ripening varieties.

Anna
Blooms February.
Large cylindrical, mostly red fruit with creamy, white
tender, crisp, sweet flesh. Harvest July-August. Best eaten
fresh. Fruit quality is better away from coast. Often has a
second crop in November. Often grows fruit the first year.
From Israel.

Braeburn
Blooms April.
Medium to large green fruit with burgundy stripes. Crisp
with sweet, slightly tart flesh. Excellent fresh or cooked.
Harvest September-October. Excellent quality, stores well.
From New Zealand.

Fuji Red
Blooms April.
Medium to large slightly flattened fruit with yellowish
green skin covered with grayish red stripes. Crisp, very
juicy, and honey sweet. Needs heavy thinning for high
quality fruit. Best eaten fresh. Ripens in October. Stores
well. From Japan. OUR MOST POPULAR APPLE!

Gala
Blooms April.
Small to medium size fruit with yellow skin and scarlet
stripes. Fine texture flesh is crisp, aromatic and spicy
sweet. Best eaten fresh. Harvest August-September. Unusually
susceptible to fireblight. From New Zealand. POPULAR

Golden Delicious
Blooms April. Medium to large fruit with yellow
(sometimes blushed pink) skin. The pale yellow flesh is
crisp, sweet and flavorful. Ripens in September. Does not
store well. (Market fruit is mealy)

Granny
Smith
Blooms April. Medium to large round
fruit with yellow green skin. the white flesh is firm,
crisp, juicy, and tart. Eaten fresh or cooked. Harvest
November-January. If left on the tree until mid-winter it
becomes a fabulous sweet yellow-skinned apple. Stores very
well. From Australia. Seems to be free from fireblight and
apple worms. EXCELLENT!

Honeycrisp
Blooms
April. Large fruit with yellow skin blushed red. Extremely
crisp, juicy, coarse, subacid and aromatic. Ripens
September, possibly earlier. From U of Minnesota. NEW! This
is an outstanding apple that we expect to do well locally.

Jonagold
Blooms April.
Large rounded fruit with yellow skin and red stripes. Cream
colored flesh is firm, crisp, juicy with outstanding flavor.
Harvest September. Excellent fresh or cooked. Pollinator is recommended. OUTSTANDING!

Pink Lady
Blooms April.
Small to medium fruit with yellow green skin heavily blushed
with rose. The white flesh is crisp, very sweet, and highly
flavored. Harvest October-December. From Australia. GREAT
NEW APPLE
Pink Pearl
Blooms
April. Medium size fruit with pale green skin with slight
red blush. The unusual pink flesh is highly aromatic with a
sweet tart flavor. Ripens early fall. Good keeper. Best with
pollinator. Pink flowers.
Spitzenberg
Blooms
April. Yellow skin overlaid with red. The yellowish flesh is
very firm, very dense, quite sweet, with superior strong
flavor. Perhaps the best tasting of all apples. Best with
pollinator. OLD VARIETY
APRICOTS
are only reliable producers
in steep canyons and
along rivers where cold winter air settles. They are not
reliable producers on hilly, or otherwise elevated,
locations in Orange County. Apricot trees grow 20 feet tall,
but can be maintained as low as 4 feet tall. Prune in summer
to control size. Genetic dwarf varieties aren’t reliable
here. Production begins the second or third year. All
varieties we offer are self-fertile.
Early Newcastle
MCR 350? Small to
medium-size fruit with pale yellow skin with soft flesh of
very good flavor and sweetness. This old variety from 1881
may be a more reliable producer locally than the newer
varieties but is more subject to brown rot.

Goldkist
MCR 300-400
Large all-purpose fruit with red blushed gold skin and good
quality firm, mildly flavored orange flesh. Ripens May-June.
Tends to develop harmless skin cracks on fruit exposed to
sun. Very vigorous tree. RECOMMENDED. This variety of
apricot has the lowest MCR .
Tropic Gold
MCR 350
Medium to large fruit, yellow skin with orange cheek. The
orange flesh is firm with excellent flavor. Ripens early
summer. NEW
CHERRIES
fruit reliably only in the canyon bottoms and in
our local mountains above 2500 feet. The MCR for most
cherries is about 700 hours. We have had some success with
two varieties.

Lapins
MCR 400(?)-800
Large, firm, dark red, sweet fruit of high quality. Harvest
in July. This self-fertile variety occasionally produces a
bumper crop at my hilltop home. We expect it to be a
decently reliable producer anywhere in Orange County where
there is a danger of flooding. (cold air flows like water)
Minnie Royal
MCR 250-500 Large, nearly black
fruit resembles Bing. Ripens early May. Requires pollination by
Royal Lee NEW! This may be the first reliable true cherry for
local areas. Cross your fingers!
Royal Lee
MCR 250-500 Medium size nearly
black fruit resembles Black Tartarian. Ripens late May. Requires
pollination by Minnie Royal. NEW!

Stella
MCR 700 Large,
black red fruit of excellent quality. Ripens summer. This
variety has produced some high quality fruit in my backyard.
FIGS
are reliable producers here. All of the varieties
we offer are self-fertile. The MCR is low or non-existent.
Trees can grow 20 feet, but are easy to maintain at 8 feet
with heavy annual pruning in winter. Most produce a few
large fruit in June (the breba crop) with a ‘second’
heavy crop of smaller fruit from late August-October.
Production begins the first year.

Black Mission
Medium
size tear-drop shaped fruit with purple-black skin and
strawberry flesh. Very rich flavor. Good fresh or dried.
Fruit won’t split open or get moldy when ripe. OUR BEST
SELLER.

Brown Turkey
Large
bell-shaped fruit with purple-brown skin and juicy, light
strawberry flesh. Best fresh. Short growing tree to about 10
feet. Excellent in containers.

Flanders
Medium to
large tear-drop shaped fruit with green and violet-bronze
skin and sweet, unusually firm flesh. Ripe fruit won’t
crack. Excellent fresh. FABULOUS.
Janice
(Seedless Kadota)
Large greenish-yellow fruit with practically no seeds. The
sweet flesh is of very good quality. Long harvest.
Peter’s Honey
Light
yellow-green fruit with dark amber flesh. Outstanding sweet
rich flavor. From Sicily.

Tiger
(Panache) Medium
size fig with cream and green striped skin and bright red
flesh. Superb cherry flavor. Not a heavy producer. Ripe
fruit tends to split and get moldy.

White Genoa
Medium size
fruit with greenish yellow skin and amber to pink flesh.
Good fresh. Best near coast, but subject to mold.
JUJUBE
(Chinese Date) is
reliably productive in all areas of Orange County but needs
inland heat to attain its best flavor, size and sweetness.
The fruit is similar in size and appearance to the common
date. The flesh has a sweet, tender, crisp apple-like flavor
fresh, or is date-like when dried or candied. Juvenile
growth is quite thorny. Mature growth has small thorns. The
weeping tree can grow 20 feet tall and is highly ornamental.
Usually produces fruit the first year. Ripens early fall.
Good in lawns. Excellent under harsh desert conditions. This
is one of the few fruit trees that will produce well even if
heavily pruned in winter. Jujube is somewhat self-fertile.
Young trees produce much larger crops if pollinated with a
different variety.
Contorted
Fruit is
similar to Li. The ornamental tree has twisted, contorted branching.
GA-866
Medium size
egg-shaped fruit with the highest sugar content of any
variety known. Relatively small weeping tree.

Li
Rounded fruit with
mahogany-brown skin. Fruit will ripen even if picked while
still somewhat green. Tree is shorter and more spreading.
Sherwood
Very large
fruit with notably dense flesh of excellent quality. Ripens
late. High productivity. Stores well. Small thorns.
MULBERRIES
are reliable in all areas of Orange County. The
fruit resembles blackberries and is very sweet when fully
ripe. Excellent fresh, dried, cooked, or for preserves.
Ripens summer. Many varieties will grow a small second crop
if the foliage on some branches is stripped a few weeks
following harvest. Easy to grow. Trees tolerate some drought
when established. Most varieties grow quickly. Fruit drop
from the dark colored varieties can stain masonry and
carpeting.
Black Beauty
(Persian)
Large black fruit with sweet, tasty flesh. Unripe fruit is
quite tart. A semi-dwarf tree that grows to only 15 feet
tall. Persian Mulberries are dormant until April.
Pakistan Red
Very long
(up to 4 inches) maroon fruit with excellent sweet flavor.
Fruit may be eaten before fully ripe. Juice doesn’t stain.
Ripens summer. Tree can grow over 20 feet tall.
Teas Weeping
Small
sweet black fruit of good quality. The small tree has
branches that weep to the ground. Very ornamental.
NECTARINES
are genetically identical to peaches but have a
smooth skin and different texture. Production begins second
or third year. All of these varieties are self-fertile.
Standard nectarine trees can grow 15 feet tall. All can be
maintained at 4 feet tall. Excess nitrogen fertilizer can
cause brown rot of the fruit.

Arctic Star
MCR 300.
Fruit has dark red skin and white flesh. Semi-freestone. Super sweet
and mild. Ripens June. Best away from immediate
coast.

Panamint
MCR 250-400.
Small to medium size fruit with red skin and golden flesh.
Freestone. Very good flavor. Ripens July.

Snow Queen
MCR 250-300.
White freestone flesh with excellent sweet, juicy flavor.
Harvest late June.
PEACHES
are reliable producers if the proper varieties are
chosen. Production begins the second or third year. All
these peaches are self-fertile. Standard peach trees grow to
15 feet tall, but can be maintained down to 4 feet tall.
Genetic dwarf peaches have not performed reliably in Orange
County.

Babcock
MCR 250. Medium
size fruit with red-blushed white skin and white flesh.
Honey sweet and juicy. Excellent quality. Semi-freestone.
Best fresh. Fruit must be heavily thinned. Ripens early
July. Longtime favorite.

Bonita
MCR 350. Huge
fruit with red-blushed yellow skin and yellow flesh. Firm
freestone with excellent flavor. Ripens late July. Not
reliable when grown on hilltop locations. SUPERB!

Donut
MCR 200-500.
Unique flat donut-shaped fruit with sunken center. White
flesh with mild sweet flavor with a hint of almond. Ripens
early July.

Red Baron
MCR 250.
Large fruit with yellow skin and flesh. Very good to
excellent quality. Freestone. Ripens mid-July. Spectacular
double rose- red flowers in spring. OUR BEST PEACH!

Tropic Snow
MCR 200.
White freestone with very good flavor. Ripens mid-June.
Showy flowers.
*Note: Currently many growers of peach
trees are getting wormy fruit (larvae of Oriental Fruit
Moth). Unfortunately, non-chemical controls have not been
totally successful. Applying Sevin to the fruit about
3-4 weeks before harvest may be the best way to stop them.
PEARS
are reliable if the proper varieties are chosen.
There are three types of pears. The familiar European pears
such as Bartlett, the Asian (A) pears with a crunchy
texture, and the Hybrid (H) pears which may display
characteristics of either parent. Most hybrid pears are
reliable producers in Orange County. Only a certain few
European and Asian varieties are reliable locally. Most
pears are partially self-fertile, but will produce far more
if pollinated with a different variety. Asian and European
pears bloom in April. Hybrid pears often bloom 2 months
earlier. Pears require 4 years to become productive.
Standard pear trees can reach 20 feet tall but can be
maintained down to 4 feet tall. Most pears should be picked
while still firm and allowed to ripen indoors. Pear trees
tolerate heavy wet soil quite well and are good lawn trees.
Hood
(H) MCR 150.
Large, pear-shaped, fruit with yellow flesh and sweet, firm,
juicy white flesh. Excellent quality. Ripens late July. This
pear rivals Bartlett for quality.
PERSIMMONS
are reliable producers in our area. Most varieties
are self-fertile. Persimmon trees can grow 30 feet tall, but
can be kept under 10 feet with pruning. Persimmons require
soil with a high oxygen content. Do not amend the soil with
organic matter. Sand, sponge rock, or pumice will help
increase air penetration. Drip irrigation is preferred.
Production begins within 4 years.

Giant Fuyu


Hachiya
Very large
oblong-conical fruit with orange red skin and flesh.
Astringent until jelly ripe. Sweet and rich. Ripens mid to
late fall. Excellent quality fresh. Wonderful dried.
Imoto
Fuyu Large
flattened, slightly squarish, fruit with dark orange skin
and flesh. The non-astringent seedless flesh is sweet and
mellow. Can be eaten while crispy or allowed to ripen until
quite soft. Ripens early to mid fall. Similar to Jiro,
perhaps a bit more tender.

Jiro
Fuyu Large
flattened, slightly squarish, fruit with dark orange skin
and flesh. The non-astringent seedless flesh is sweet and
mellow. Can be eaten while crispy or allowed to ripen until
quite soft. Ripens early to mid fall. Relatively vigorous
tree. THE MOST COMMON COMMERCIAL FUYU.
PLUMS
are notably finicky producers. Most reliable
production occurs in canyon locations. Production begins
within 4 years. Standard plums grow to 30 feet tall but can
maintained down to 4 feet tall. There are no genetic dwarf
varieties that perform well in our area. All these varieties
are Japanese.

Burgundy
MCR 350.
Medium size fruit with dark burgundy skin and firm purple
flesh. Sweet and mellow with a small pit. Ripens July-August
over a 2 month period! Self-fertile. Reliable in most
locations except hilltop gardens. OUR BEST PLUM.

Green Gage
MCR 400-600. Small to medium size
fruit with yellowish green skin and greenish yellow flesh. Sweet,
aromatic, juicy and often a bit tart. Ripens July. Good production
inland

Santa Rosa
MCR 300-500.
Large oval fruit with purplish skin and amber flesh tinted
red. Juicy and sweet with a tart skin. Ripens June.
Self-fertile. Reliable most locations. POPULAR
PLUOTS
are relatively new and
untested. Genetically they are hybrids between plum and
apricot. The fruit is extremely sweet and commonly wins top
honors at fruit tasting sessions. New varieties are being
developed presently. Genetically pluots are 75% plum and 25%
apricot

Flavor Grenade
(Pluot)
MCR 300-600. Elongated green fruit with red blush. The flesh
is crisp with incredible flavor. Excellent hang time on
tree. NEW! No local experience yet.

Flavor King
(Pluot) MCR
300-600. Large fruit with maroon skin and red flesh.
Outstanding flavor. Harvest August. This variety seems to
need little winter chill, however, it may require a
pollinator such as Burgundy Plum to bloom with it.
POMEGRANATES
are easy to grow in Orange County.
Flavor and sweetness is best in the warmer inland areas. All
are self-fertile. Some production may begin early, but
reliable harvest begins by the fourth year. Ripens Fall. Can
grow more than 15 feet tall, but can be maintained as low as
4 feet tall. Pomegranate trees are highly ornamental and the
attractive orange flowers bloom for several months. Water
consistently or fruit will split before ripening.
Ambrosia
Very large
round fruit with rosy golden skin and bright carmine flesh.
Very good tart-sweet flavor. Good quality even along coast.

Angel Red
Eversweet
Medium to
large fruit with pale pink skin and pale red, non-staining
flesh. Very sweet and mellow. The soft seeds and non-bitter
membranes are also edible. Ripens mid September.
Sweet
Large fruit with
pinkish green skin and light red flesh. Very sweet and
mellow. Relatively soft seeds. Ripens late September.

Wonderful
Large fruit
with red skin and ruby flesh. Sweet-tart flavor. THE
COMMERCIAL POMEGRANATE.
QUINCES
do well in Orange County. The large pear-shaped
fruit has extremely firm flesh and is usually cooked before
eating. Quince are most often used to make jams and jellies.
Quince trees tolerate poor conditions. Quince begin
production the second or third year. Trees can grow 15 feet
tall and can be maintained as low as 4 feet tall. Fireblight
is a preventable disease that can cause major damage to the
tree.
Smyrna
Very large fruit
with yellow skin and tender light yellow flesh. Ripens fall.
Good to very good quality. From Turkey.
