The Meyer lemon is one of the hardier of the home-grown citrus fruit species. Dwarf varieties will grow well in containers filled with light, well-drained soil. Outdoor Meyer trees thrive in hot climates in the southernmost regions on the U.S. and along some of the Pacific coastline. A well-tended plant will bear fruit for much of the year, particularly from December to April, according to Purdue University. The right watering schedule, pruning technique and fertilizer all help to keep your Meyer lemon tree healthy.
Cut suckers from the trunk. Suckers are small stems that develop as low offshoots from the trunk. As the name suggests, suckers drain energy from the plant and impede general growth.
Prune any dead, damaged or long and weak branches from the tree. Snip off any stems that double back or cross each other. Cut back the branches to your desired size. Prune the tree in winter to avoid summer sunburn on the trunk and limbs, advises the University of California, Davis.
Water young Meyer lemon trees about twice a week in the summer, recommends the MeyerLemonTree.com. Water deeply to ensure water reaches the root system. Water container plants more frequently.
Push your finger into the soil around the tree or use a trowel to dig a small hole. Don't water soil that's moist in the first 2 inches.
Keep grass and mulch at least 1 foot from the base of the tree trunk to prevent rot. Mulch ground near the tree in hot climates, or when the weather cools down.
Add 1/3 cup of ammonium sulfate in February, May and September, advises Texas A&M University. Increase the amount for each year by adding 1 cup per year. For example, use 3 cups split into three 1-cup doses for a three-year-old tree.
