What are Spanish limes? Spanish limes, or Mamoncillo, are clusters of fruit that resemble small limes, but have a tough, outer shell and a lychee-like inside. The taste has been described as a cross between limes and lychees, and, although they can be a little hard to open and eat, they’re well worth the effort!

What Are Spanish Limes

As noted above, Spanish limes, or Mamoncillo, are a tropical fruit that grow in clusters of 12-15 on big trees. These fruits have a hard outer shells and a soft, jelly-like inside. Once you’ve consumed the fleshy, jelly-like part, there will be a large round seed inside. Contrary to popular belief, Spanish limes are NOT part of the citrus family, but rather are part of the Soapberry family.

The seed inside is big and white, and depending when picked, Spanish limes can taste anywhere from really tart and sour (when picked early) or sweet (when picked later!). Spanish limes cannot take temperatures below 25F (-4C).

Requirements for Growing Spanish Limes:

Sun:

Because this is a tropical and subtropical tree, it will need to be planted in a spot with full sun.

Soil:

Spanish limes can grow in almost any type of soil, so long as the soil is well draining.

Water:

Although Spanish lime trees are drought resistant, young trees (4 years old and younger), will need regular watering until they are established.

Propagation:

Spanish limes can be grown from seeds, but the best and easiest way to grow Spanish limes is to purchase an already grown young tree. Planting from seed can take a long time (8-10 years) to fruit. Once you’ve acquired the young tree, plant in an area with full sun and lots of space.

Spanish Lime Care:

Fertilizer:

Young mamoncillo trees need to be fertilized with a complete balanced fertilizer every other month. Twice a year, apply manure around the tree. Once the tree is established (after 4 years), feed it with a phosphorous and potassium-rich fertilizer.

Pruning:

Regular pruning should be done to control its size. Mamoncillo trees can grow to be very tall, so controlling the height is very important.

Harvesting:

After about 4 or 5 years, your Spanish lime tree will start giving off fruits. This will happen in early summer and fall. You’ll know it’s ready to harvest once the fruit’s outer shell becomes brittle and easily breakable.

Diseases & Pests:

Spanish lime trees can be susceptible to fruit flies and citrus black flies. Keep an eye out for leaf spot and green scurf as they can be common diseases in these types of trees.
