FRUIT TREES

FOR DESERT CLIMATES

STARNOTE 505

June 2009

Choose wisely for best results

 

Deciduous fruit trees do surprisingly well here in the Desert. One factor to be considered is called “Winter Chill Hours” and are expressed as “Low (400 or less), Moderate (400 to 700) and High (over 700) hours of winter temperatures below 45 ˚ F. The lower the winter chill requirement for a tree is, the better the chance for high production in our climate. Warmer winters will negatively affect high chill requirement trees more than those with low chill requirement.

 

Temperatures in the range of 45 to 55 degrees also have considerable benefit toward fruiting. Conversely, temperatures above 70 degrees during the cooling period may be detrimental to fruit production. Production is also affected by proper watering and fertilizing as well as unusual hot or cold spells during the flowering period.

 

Follow proper planting and care instructions described by StarNote 500, Fruit Tree Selection, Planting and Care and you will be successful.  If you have specific questions about any fruit tree, discuss them with a friendly sales associate at any Star Nursery location.

POLLINATORSSome fruit trees need pollinators in order to produce fruit.  Any tree needing a pollinator usually needs a different variety of the same fruit.  Some, but not all; are listed below.  Peaches and nectarines can cross pollinate within certain limits. 

 

VARIETIESThe following fruits are most often available and commonly grown in our climate with varying degrees of success.  Citrus varieties are listed in StarNote 510, Growing Citrus in our Climate.  (top)

 

ALMONDS are among the easiest to grow of all fruits or nuts in the desert.  Most varieties benefit from a pollinator.  Almonds are drought resistant and produce better with deep, infrequent irrigation.

 

APPLES have been grown in our climate for some time. Harder, more tart apples seem to take summer heat well without turning mushy.  All apples benefit from a pollinator. Yellow Delicious and Dorsett Golden pollinate most other varieties. Fruit is produced on short branches called spurs. These occur on wood at least two years old.  Spurs may be productive for many years so restrict pruning on mature trees to removal of weak or dead wood and crossing branches. Young trees may take 3-5 years after planting to develop fruiting spurs.  (top)

 

APRICOTS bloom early and generally grow best where late frosts seldom occur. They are dependable, heavy bearers in desert climates. All are self fertile; chilling requirements are not a factor. Thin fruit in early spring, as necessary, to prevent overloading branches. Most container stock produces fruit the first year after planting.  When the birds start pecking, it’s time to pick ‘em!

 

CHERRIES will survive in hot climates but they do not thrive.  All varieties have High Winter Chill requirements which makes them better suited to cooler areas.  On young trees, thin, tender bark is best protected with white latex paint which prevents sunburn, splitting bark and helps prevent invasion by borers.   Prune to maintain good branch structure only.  Fruiting spurs are long-lived and do not need to be renewed.  (top)

 

FIGS are among the easiest fruits to grow in desert and semi-desert climates.  Though naturally large in size, some varieties reaching 40 feet or more, all can be kept small by pruning heavily.  In cooler areas they may freeze back in severe winters, keeping them in large shrub form. Prune out dead wood or runaway shoots annually and avoid high nitrogen fertilizers.  Figs make excellent container plants.  All varieties grown here are self-fertile.

 

GRAPES are easily grown in our climate.  They tend to be a little smaller, but much sweeter than those grown elsewhere.  Pruning for maximum fruit production is a complicated affair, but remember that next year’s fruit is produced from this year’s wood.  In most cases, plenty of grapes will be produced on vines used to cover an arbor.  When planted in southern or western exposures, they can provide valuable shade as well.  The grape-leaf skeletonizer is a native pest that can destroy leaves.  Control with Bacillus thuringensis (BT) products.  (top)

 

NECTARINES tend to be shorter lived in our climate but produce excellent fruit; well worth your efforts.  Trees are not well suited for lawns and need regular fertilizing and pruning for best production.  Keep tops of trees pruned to control size if desired. Dwarf varieties give full-sized fruit on 5 to 6 foot trees and are well-adapted to container gardening.  Plant different varieties for early, mid or late season fruit.  Thin fruit in early spring to avoid branch breakage.

 

PEACHES  also have a relatively shorter life span (about 8 years) but produce heavily and are easy to grow, especially if planted out of lawns. All benefit from regular fertilization and pruning.  Dwarf varieties give full-sized fruit on 5 to 6 foot trees and make great choices for container gardening.  Plant different varieties for early, mid or late season fruit.  Thin fruit in early spring, as necessary, to prevent overloading branches.  Stone fruits ripen from the inside out and may smell ripe while still hard. If birds start pecking the fruit, it’s a pretty good indication that harvest time is at hand. Pick when colorful and full-sized and they will soften nicely indoors in 2 to 3 days while retaining all their flavor.  (top)

 

PEARS grow remarkably well in our climate; not grown as much as they should be.  Most varieties take lawn conditions better than many other fruit trees and have a greater tolerance for wet, heavy soils.  Fruit is best if harvested before ripe and allowed to ripen indoors.  Fireblight resistant varieties and those most often available are:

 

PECANS grow easily in the southwest, contrary to popular belief.  However, container stock is sometimes difficult to find.  They make excellent shade trees in large yards.  Give them good drainage!  Be sure to plant western varieties which are suited to hotter climates and alkaline soils.  Most bear without a pollinator but all benefit from one.  Mahan and Mohawk may be best since both are smaller and bear young.

Popular varieties.  Cheyenne, Choctaw, Mahan, Mohawk, Navajo, Pawnee, Sioux, Tejas, Western Schley.  (top)

 

PERSIMMONS are highly ornamental and Asian varieties do quite well here.  They will perform better with afternoon shade and amended, well-drained soil.  The popular varieties most often sold are Fuyu and Hachiya.

 

PISTACHIOS grow very well here in the desert. If you enjoy eating them, you will need to plant a male (Peters) and a female (Kernan) in order to get fruit. The male will not fruit, but it’s pollin is vital.

 

PLUMS occur in Japanese and European varieties.  Japanese strains typically have larger, juicer fruit and are used primarily for fresh eating.  European plums include prunes which have higher sugar content and are good fresh or dried.   Most varieties are well adapted to our climate and are self fertile except as noted.  Prepare your soil well, make sure the drainage is good and give an iron supplement like “Ironite” each year to control chlorosis.  (top)

 

POMEGRANATES are among the prettiest, strongest and most productive fruits for dry climates.   They tolerate heavy, alkaline soils, are extremely drought tolerant when established and make nice ornamental trees as well.  Fruit is produced on new wood so prune to shape as desired.  Dwarf flowering varieties produce no edible fruit but make a colorful, ever blooming accent to any dry landscape.

Varieties.  Sweet – reddish pink flowers spring through fall followed by lots of tasty, pink fleshed fruit on a short, bushy tree.  Wonderful – bright, orange red flowers followed by sweet, reddish purple fruit on a fountain shaped tree to 10 feet or more.  (top)

 

REASONS TREES DO NOT FRUIT

 

Age:  Many varieties need to be 3 to 4 years old or even older in the case of Pecans.  Most container stock is fruiting age or within one season of fruit bearing age.  Older trees may need pruning or proper fertilizing to produce.

 

FrostLate frosts during blooming period, especially after a late winter warm spell.

 

PollinationIf you’re buying a single variety, make sure it is self-fertile.  Rains or strong winds can affect blooms and fruit set.  (top)

 

Pruning Removal of fruiting wood or spurs or pruning at the wrong time will have severe impact on fruit production.  Consult Ortho’sÒ All About Pruning book or ask a friendly Star Nursery sales associate.

 

LocationPlanting in high wind areas can cause fruit loss.  Chilling hours can be affected by how close the tree is planted to a warm object like a building or block wall.  (top)

 

Watering/fertilizingOver-watering can cause premature fruit drop.  Failure to use deep, infrequent watering techniques can also cause fruit drop.  Lack of fertilizer at critical times, especially fall, or excessive nitrogen can negatively affect fruit production next year.

 

Proper Planting or Drainage: If a tree has been planted too deeply (soil over the root-ball) or the hole has bad drainage, there will be insufficient oxygen for the roots to properly respire (a vital process for a plant to convert sugars into energy), the tree is likely not to produce many (or any) blooms and often the fruit the sets will not grow properly. Watering too frequently will cause similar symptoms.  (top)
