Citrus trees that are being planted outdoors in the ground are best planted at the beginning of spring or after, so the trees benefit from the longest growing season possible. Citrus trees planted in pots to be grown indoors can be planted at any time.
The average lifespan of a citrus tree is approximately 50 years. This age applies to both standard size and dwarf citrus. Trees begin producing fruit sometime during their second through fifth growing season, and continue to produce fruit throughout their lifespan.
Start by watering newly planted or potted trees deeply once per week for the first month. Adjust accordingly by monitoring soil dampness. If the soil is still damp down to 2 inches deep after the fourth week, wait to water for another few days. Always water deeply, and don’t let the soil get dry to below five inches. Also, never water so much that you let your citrus tree remain in standing water or constantly saturated soil.
Grafted citrus trees will begin to consistently produce fruit after two to three years in the ground or in a suitable container. Variations in fertilizer, water, sun, temperature, and other environmental factors can all affect how soon and how much fruit a given citrus tree grows. Citrus trees grown from seed will take much longer to mature to fruit-growing age: seven to ten years is common.
No. Dwarf trees will produce fruit at least as fast as standard sized trees, and in some cases faster, because the smaller trees reach their maturity quicker.
Citrus trees like sandy loam soil that is well drained. A suitable mixture is three parts potting soil, one part composted manure (such as composted cow or chicken manure), one part perlite, and one part clean sand. You can also mix equal parts regular potting mix and cactus mix soil.
Yes. Any time you move a potted citrus tree from indoors to out (for example in the summer) or from outdoors to in (to overwinter the tree inside) it is normal for the tree to drop leaves. Once the tree has adjusted to the move, new leaves will begin to grow. This reaction does not harm the long-term growth of the tree.
Many circumstances can cause falling leaves on a citrus tree. One is overwatering. A second is adequate watering, but poorly drained, or saturated soil. Also, some pests or diseases may cause yellowing leaves that fall away, such as aphids, canker, or some fungi. Finally, it is possible that a lack of nutrients is causing the falling leaves.
Yes. You can over-winter a potted citrus tree indoors as long as it gets ample water and light.
Zone 8 is the coldest USDA Zone where citrus is known to live in the ground successfully. However, in any zone, extended periods of freezing weather can be detrimental to the health and even the survival of any citrus tree. Bring potted citrus indoors when there is a chance of frost, and water in-ground trees fully when cold weather approaches.
