Citrus Growing
When to plant
Generally, citrus trees can be planted any time of year, depending on the specific climate, but
should be planted so that the roots have a chance to acclimatize before extreme temperatures are
expected.
Where to plant
Citrus can be planted in containers indoors or outdoors, or in the ground. Soil pH should be
slightly acidic to about neutral (6.0 to 7.5) and soil depth should be a minimum of 18 inches
deep. Sandy to clay loam soils are best, with good drainage a must.
A site in full sun protected from severe wind is best. Be aware that some types, such as
grapefruit, require more heat to produce sweet, tasty fruit. Planting higher on a slope can provide
some protection from cold air.
Transplanting from a container to the ground
Handle the tree gently and protect the roots from damage. Dig a hole about twice as wide as the
rootball of the tree and about the same depth as the rootball. Save the soil for backfill; break up
large clumps. Soil amendments are not recommended unless the soil is extremely sandy or is
heavy clay.
Trees should be planted at the same depth as they were in the container. If planted too deep, soil
and water tend to stand against the trunk, which promotes root and crown rots such as
Phytophthora. If planted too high, the roots will dry out too quickly.
Planting in a Container
To create the ideal growing medium for citrus, start with a commercially available soil mix that
does not contain chemical wetting agents. Evenly combine a 1/4 1/3 volume of redwood or
cedar shavings with the commercial soil mix, cedar hamster bedding is widely available and
inexpensive.
Use a container that allows for good drainage and has at least five drainage holes. When planted
at the correct height the thicker woody “crown” roots will show just at or above the soil line and
the fine feeder roots below will be covered with soil. Do not cover the trunk with soil. Putting
gravel on the bottom of the pot can impede drainage, so is not recommended.
Watering
Citrus trees require consistently moist but not soggy soil and they do not like standing water. The
root system should not be allowed to dry out, which stresses the tree. Note however, that
overwatering and/or poor drainage are also problems, and equally stressful. Citrus trees are
evergreen, and should be irrigated year-round, especially during active growth periods, usually
late winter or early spring through summer. Young trees with a trunk diameter of less than an
inch are especially vulnerable to irrigation issues. Irrigation should be at the root zone area away
