The tropical Loquat can grow in the Arizona desert if protected from the afternoon sun and given adequate water. They do well with eastern exposure and filtered sun. The large exotic-looking foliage is very attractive and select varieties produce delicious fruit.
Loquats are sensitive to salty soil and specific nutrient deficiencies. Since local water is already high in salts, do not use chemical based nitrogen fertilizers. Compost and organic fertilizers such as fish emulsion (0-10-10) are beneficial. High alkalinity can lead to magnesium deficiency causing old leaves to dry. Protect newly planted trees from summer heat until established.
Seedling trees usually begin to bear fruit in about 8 to 10 years.
