How To Grow Babaco: Best Tips And Advice

Learn how to successfully grow babaco trees with the right location, soil preparation, planting steps, care techniques, and solutions for issues.

Choose the Right Location for Your Babaco Tree

Babaco trees require full sunlight and well-drained soil to produce fruit. At least 6-8 hours of direct sunlight per day is ideal for a babaco tree. The soil should be sandy, loamy, and fertile. Heavy, clay soils do not drain well and will harm the babaco tree.
Before planting, test the soil pH and ensure it is between 6 and 7.5. Add compost or organic matter to enrich the soil. Dig a hole 3 feet wide and 2-3 feet deep, removing any weeds or rocks. Refill the hole with enriched soil. The babaco has shallow roots, so plant it in the center of the prepared hole and tamp down the soil firmly with your hands after planting. Water thoroughly after planting and mulch around the base of the tree to help retain moisture in the soil.
With the proper location and soil conditions, a babaco tree will produce plenty of the pear-shaped fruit. The fruit has a slight citrus flavor and is commonly used in salads, chutneys, and desserts. With care and maintenance, a single babaco tree can remain productive for 15-20 years.

Prepare the Soil for Babaco Planting

Before planting a babaco tree, it is important to prepare the soil properly to provide the nutrients and conditions it needs to thrive. Test the soil pH and ensure it is slightly acidic, between 6 and 7.5. If needed, add compost or other organic matter to adjust the pH and enrich the soil with nutrients.

A babaco tree needs a large planting hole, at least 3 feet wide and 2-3 feet deep. Remove any weeds, rocks or debris from the hole. The enriched soil should be sandy and loamy, and drain well. Heavy, clay soils will not suit a babaco tree.

Nutrient Importance
Nitrogen Promotes leafy growth and fruit production
Phosphorus Helps with root growth and plant maturity
Potassium Essential for plant vigor and disease resistance
Calcium Important for plant structure and growth
Magnesium Required for chlorophyll production

Fertilize the babaco tree with a balanced, all-purpose fertilizer once a month during the growing season. Provide 1/4 to 1/2 pound of 5-10-10 fertilizer for every year of the tree’s age. Spread the fertilizer evenly around the base of the tree, avoiding direct contact with the trunk. Water thoroughly after fertilizing.

• Mulch around the base of the tree with 3 to 4 inches of compost, chopped leaves, straw, or wood chips. Mulch will help retain moisture in the soil, suppress weeds, and provide nutrients as it decomposes.

• For the first year, water the babaco tree regularly to keep the soil consistently damp. The top few inches of soil should dry out between waterings. Watering thoroughly but allowing the top layer of soil to dry will promote deep root growth.

• Once the tree is established, it can tolerate some dry conditions, but water during extended drought periods. The babaco tree can live 15-20 years or more with proper care and feeding.

Planting Babaco: Step-by-Step Guide

After preparing the planting area and soil, you are ready to plant the babaco tree. For the best results, plant the babaco as soon as possible after purchasing. Exposing the roots to air for long periods can damage the plant, so do not delay planting.

  1. Water the seedling thoroughly before removing it from the container. Gently loosen the root ball to encourage outward growth. Do not disturb the roots too much.
  2. Dig a hole in the center of the prepared area. The hole should be slightly wider and deeper than the root ball. Place some enriched soil in the bottom of the hole to support the tree at the proper level.
  3. Place the seedling in the hole and backfill the soil around it. Ensure the seedling is planted at the same depth as in the container. If planted too deep, the stem can rot. If planted too high, the roots can dry out.
  4. After placing the seedling in the hole, fill in and tamp down the remaining soil firmly around the base of the plant with your hands. This will remove any air pockets and provide support for the seedling’s shallow roots.
  5. Create a depression or well around the base of the seedling to help hold water. Water the newly planted tree thoroughly until water flows out the drainage holes at the bottom of the container or planting site.
  6. Place 3 to 4 inches of mulch around the base of the seedling but avoid contact with the trunk. The mulch will help the soil retain moisture as the tree becomes established.
  7. Fertilize the newly planted tree at half the recommended rate 2-4 weeks after planting. Provide water and nutrients to help the young babaco tree overcome the stress of transplanting.
  8. Stake the seedling to provide support if needed. Place the stakes 6 to 12 inches away from the trunk and secure the seedling to the stakes with tree ties.

Follow-up care like regular watering, fertilizing, and pruning will help ensure the success of the newly planted babaco tree. With the right conditions, the tree will produce fruit within 2 to 3 years.

Babaco Tree Care: Watering, Fertilizing, and Pruning

Proper care and maintenance of a babaco tree will help ensure healthy growth and maximum fruit production. Key aspects of babaco tree care include:

Watering: Water babaco trees regularly, especially for the first few years after planting. The top few inches of soil should dry out between waterings. Waterlogged soil can lead to root rot. Once established, babaco trees can tolerate some drought but should receive about 1-2 inches of water per week.

Fertilizing: Fertilize babaco trees every 4 to 6 weeks during the growing season. Use a balanced, all-purpose fertilizer with equal parts nitrogen, phosphorus, and potassium such as 10-10-10. Apply 1/2 to 1 pound of fertilizer for every year of the tree’s age. Spread fertilizer evenly under the tree canopy, avoiding direct contact with the trunk. Always water after fertilizing.

Pruning: Prune babaco trees to improve light penetration and airflow. Remove dead or dying leaves and stems. Lightly prune outer branches to thin the canopy and open the center to light and air circulation. Avoid heavy pruning which can reduce fruit production for up to a year.

Annual maintenance:

• Apply mulch around the base of the tree each year after the last frost to help retain moisture in the soil and prevent weeds. Pull weeds regularly, especially when the tree is young.

• Check the trunk bark and leaf petioles regularly for signs of pests or disease and treat if needed. Common babaco pests include aphids, mealybugs, and spider mites.

• Whitewash the tree trunk with a 50/50 mixture of water and white interior paint each year. Painting the trunk helps prevent sunburn damage. Avoid getting paint on the leaves.

• Remove fruit once they start to soften and turn slightly yellow. The fruit can be pickled, juiced, or used in chutneys and desserts. When harvesting, cut the fruit from the tree rather than pulling to avoid damage.

• Replenish the mulch and fertilizer during midsummer to provide nutrients for the second flush of growth. Water consistently into the early fall before temperatures drop.

With the proper care and annual maintenance, a babaco tree can produce fruit for 15-20 years or more. The tree may reach up to 20 feet tall, producing 200 or more fruit in a season.

Common Babaco Growing Problems and Solutions

While babaco trees are relatively low-maintenance, there are some common problems to watch for. By addressing issues early, you can ensure the health of your babaco tree and a successful harvest.

Root rot: Root rot is caused by overwatering and poorly drained soil. It shows up as brown, mushy roots and causes leaf drop, stunting, and death of the tree if untreated. Improve drainage and allow the top few inches of soil to dry between waterings. Root rot treatment may require fungicides.

Nutrient deficiencies: Lack of nutrients can cause yellowing leaves (chlorosis) and poor growth. Do a soil test and check that the pH is between 6 and 7.5. Fertilize with a balanced tree fertilizer and compost to restore nutrients. Magnesium, nitrogen, and iron deficiencies are most common in babaco.

Sunburn: Intense sunlight can burn the leaves, especially if the tree is newly planted or pruned. Sunburn causes bleached, dry patches on leaves. Whitewash the tree trunk and provide shade during the hottest parts of the day. Sunburn damage is usually minor, but repeated damage weakens the tree.

Pests: Common babaco pests include:

Aphids: Suck sap from leaves and shoots. Look for yellowing, distorted leaves and sticky honeydew. Spray with insecticidal soap or release ladybugs, which prey on aphids.

Mealybugs: Suck sap from leaves and stems. Look for white fluffy wax and honeydew. Remove by hand or spray with insecticidal soap.

Spider mites: Feed on leaves, causing stippling and webbing on undersides of leaves. Spray leaves with water to wash away webbing and mites. In severe infestations, apply miticide or predatory mites.

Scale: Sap-sucking insects attached to leaves and shoots. Look for circular or oval bumps on stems and leaves. Remove by hand or spray with horticultural oil or insecticide.

Birds and rodents: Netting or traps may be necessary if birds, rats or other rodents become a problem. They can damage fruit, buds, and branches.

By properly caring for babaco trees and monitoring them regularly, most common problems can be avoided or caught and treated early before long term damage occurs. Healthy, well-maintained babaco trees will produce an abundant harvest for many years.
