Soil type: clay or limestone, well drained.

Soil drainage: The poorly drained soil can lead to flooding and, consequently, to root suffocation.

Soil reaction: soil pH must be between 6.5 and 7.5. Calcium deficiency has to be be avoided.

Acerola reproduction

Acerola can be reproduced by seed and multiplied by cuttings.

Sexual reproduction by seed: seed germination may have very low capacity and it is not always feasible. Choose seeds from plants that have not been exposed to cross-pollination with other species of fruit. Clean and dry the seeds treated with fungicide. The germination rate is 50% or sometimes only 5%.

Asexual reproduction by cuttings: Performed in adult trees of 3-4 years old. You must take a cutting 12 – 15mm. thick and 25cm. long. Put it in a propagator with hormones until roots appear. It is the most used propagation method.

Other cultivation tips

– This plant produces fruit after 1,5 – 2,5 years after planting.

– It fruits from 3 to 4 times a year or more.

– Acerola is a rainfed crop. It should only be watered to foster flowering and in moderate amounts. It does not want over-watering.

– Protect it from frost in greenhouses or cover cover the tree with plastic

Picking up acerolas

For home use, the fruits are picked when fully ripe. If you want to make marmalades or jams, they can be harvested slightly immature, when they are changing from yellow to red.

Acerola pests and diseases

  • Root-knot nematodes (Meloidogyne spp.) They cause serious problems to roots because they form a sort of swelling in roots, called galls. This especially happens when they attack the young trees. It affects the productivity of fruits.
  • Insects: aphids, whiteflies, etc.
  • Acerola weevils (Anthonomus spp.): Some are serious agricultural pests that limit acerola production.
  • Fungi (Cercospora spp.): Cercospora is the main fungal disease, especially in tropical crops. It is characterized by spots on the leaves. Apply a suitable fungicide.
