How To Grow Genip: Best Tips And Advice

Learn how to grow genip with these tips on choosing the right location, preparing soil, watering, pruning, and protecting against pests and diseases.

Choose the Right Location for Your Genip Tree

The most important factor in successfully growing genip trees is providing the right location. Genip trees require plenty of sunlight and warm temperatures to thrive. They grow best in tropical and subtropical climates with little chance of frost. Ideally, genip trees should receive at least 6 to 8 hours of direct sunlight per day.

When choosing a spot for your genip tree, consider available sunlight and shade from nearby structures and plants. The more sunlight a location receives, the more fruit your genip tree will produce. Genip trees can reach up to 40 feet in height and width, so select a spot with ample space. Avoid planting genip trees close to buildings, as their dense canopy and spreading roots can cause damage.

Though native to Southeast Asia, the [[Mauritius|Mauritius]] genip has naturalized in tropical regions around the world. In these areas, genip trees thrive in sandy, loamy soil with a slightly acidic pH between 5 to 6.5. The soil should be deep, fertile, and well-draining to support healthy growth. Before planting, enrich the soil with compost or manure to provide nutrients for your genip tree. With the right location and soil conditions, your genip tree will produce an abundance of sweet, red-skinned fruit.

Preparing the Soil for Maximum Growth

Preparing the soil before planting is crucial to the health and productivity of your genip tree. Genip trees require fertile, well-drained soil with a slightly acidic pH between 5 to 6.5 to thrive. The ideal soil for genip trees should be sandy loam, with plenty of organic matter to provide nutrients.

To prepare the soil for planting:

  1. Test your soil pH and nutrient levels. For genip trees, aim for a pH between 5 to 6.5. The soil should be rich in nutrients like nitrogen, phosphorus, and potassium.
  2. Till the soil to a depth of at least 2 to 3 feet to loosen the soil and improve drainage. Genip tree roots grow rapidly and spread widely, so deep, loose soil is important.
  3. Improve drainage and aeration by mixing in compost or other organic matter. Peat moss, composted manure, and sand can all help improve drainage for genip trees.Aim for mixing in 2 to 4 inches of organic matter into the top 6 to 12 inches of soil.
  4. Add fertilizer to enrich the soil. For new plantings, add balanced, all-purpose fertilizer at a rate of 1 pound per 100 square feet of canopy space. Use a fertilizer with equal parts nitrogen, phosphorus, and potassium, such as 10-10-10.
  5. Consider soil amendments based on the results of your soil test. To increase soil acidity, add powdered sulfur. For alkaline soils, try ammonium sulfate or aluminum sulfate. To boost nutrients, add compost, blood meal, bone meal, or kelp meal based on the needs in your soil.
  6. Mulch around the base of the tree after planting to suppress weeds, increase moisture retention, and protect the root zone. 2 to 3 inches of wood chips, shredded bark, compost, or pine needles make excellent mulch for newly planted genip trees.

With the proper soil preparation before planting, your genip tree will have all the nutrients and conditions it needs to become established in its new environment. Healthy soil leads to healthy, productive trees, so take the time to improve your soil before putting your genip tree in the ground.

Watering and Fertilizing Your Genip Tree

Providing proper watering and fertilization is key to the health and productivity of your genip tree. Genip trees need moist soil for the best growth, especially in the first few years after planting. Water stress can stunt the growth of young genip trees and reduce fruit yield. Fertilizing will supply the nutrients genip trees need to produce abundant foliage and fruit.


Genip trees should receive at least 1 inch of water per week. Water young genip trees regularly,especially in hot or droughty weather. Soil should remain consistently moist but not soggy. It is best to water genip trees in the morning to minimize disease risk.

The water needs of genip trees decrease once established. Mature genip trees can tolerate some drought, but fruit production will decrease if the soil dries out. Monitor mature genip trees and water when the top few inches of soil are dry. Continue to provide at least 1 inch of water per week during fruit development.

Overwatering can be as damaging as underwatering. Genip trees do not grow well in saturated soil conditions. To ensure proper drainage, plant genip trees in well-draining soil and avoid planting in low areas where water collects.


Fertilize genip trees regularly during the growing season. Start fertilizing genip trees about one month after planting. Use a balanced, all-purpose fertilizer with equal parts nitrogen, phosphorus, and potassium such as 8-8-8 or 10-10-10. Follow the directions on the product to determine proper rate and method of application.

For mature genip trees, fertilize every few months during the growing season. Increase the rate slightly with the size and age of the tree. Never overfertilize, as this can harm your genip tree. Watch for signs of overfertilization like burnt leaf tips or a strong flush of foliage growth with little fruiting.

With the right amount of water and fertilizer, your genip tree will produce healthy green foliage and abundant crops of sweet, red fruit. Take the time to monitor your tree’s needs and adjust your watering and fertilizing routine based on the age, size, weather conditions, and fruiting of your genip tree.

Pruning and Training Your Genip Tree

Pruning and training your genip tree from an early age will help establish a strong structure and open canopy. Proper pruning improves air circulation, light penetration, and overall tree health. It also aids in fruit production by allowing adequate sunlight to reach developing fruit.

The goals of pruning a genip tree are:

  1. Establish a strong central leader and wide-angled branch attachments. Prune away any weak or narrow-angled branches.
  2. Thin out branches to improve air flow and light exposure. Remove any dead or crossing branches.
  3. Reduce the canopy height to ease harvesting. Genip trees can reach up to 40 feet, so pruning helps contain their size.
  4. Stimulate new foliage and fruiting wood. pruning results in vigorous new growth, which will bear fruiting spurs.

Pruning genip trees is best done after the threat of frost has passed but before new growth starts in the spring. For young genip trees, pruning should be done annually to train the tree structure. Mature trees require pruning every 2-3 years to maintain an open canopy and contain size.

Use pruning shears and loppers to remove branches up to 2 inches in diameter. For larger branches, use pruning saws. When pruning, cut branches at their point of origin or back to a lateral branch. Avoid leaving stubs behind, as these can lead to pest infestation or disease. Only remove about 25% of living branches at a time to avoid stunting the tree.

With consistent and careful pruning, your genip tree will develop an open, spreading canopy that allows for maximum light exposure and air circulation. Pruning, combined with proper fertilizing and watering, will also stimulate new growth and increase fruit yields from your genip tree. An well-maintained genip tree can produce fruit for 40-50 years, so taking the time to prune your tree properly is well worth the effort.

Protecting Your Genip Tree from Pests and Diseases

While genip trees are generally low-maintenance, they can still face issues like pests, diseases, and fungal infections. Protecting your genip tree requires monitoring for common problems and taking preventative actions. With vigilance and care, many potential issues can be avoided or dealt with before they significantly impact your genip tree.

Some potential pests of genip trees include:

  • Aphids: Small, soft-bodied insects that feed on new growth. Treat with insecticidal soap or neem oil.
  • Scale: Sap-sucking insects that attach themselves to leaves and branches. Prune off badly infested branches and treat with horticultural oil.
  • Spider mites: Microscopic spider relatives that spin webs and feed on leaves. Increase humidity around genip tree and treat with insecticidal soap.
  • Mealybugs: Soft, flat, oval insects that cluster on leaves and fruit. Use a cotton swab dipped in rubbing alcohol to dab mealybugs. Repeat applications may be needed.

Diseases and fungi to watch for:

  • Anthracnose: Fungal disease that causes leaf and fruit spots. Improve air circulation, sanitize pruning tools, apply fungicides containing copper.
  • Bacterial leaf spot: Bacterial infection leading to leaf lesions and defoliation. Improve drainage and sanitation, apply copper-based sprays, remove affected leaves.
  • Phytophthora root rot: Soil-dwelling fungus that rots roots and leads to leaf wilt or drop. Improve drainage, do not overwater, apply fungicides for prevention.

The key to protecting genip trees is maintaining healthy trees through proper care and sanitation. Frequently inspect your tree for any signs of pests or disease and treat issues early. Ensure adequate drainage and air circulation around your genip tree. Sterilize pruning tools in between cuts to avoid spreading infections. Apply appropriate treatments at the first signs of problems based on the pest or disease affecting your genip tree. With diligence, you can prevent many harmful issues from significantly impacting your tree.

Healthy, pest-and disease-free genip trees will reward your efforts with vigorous foliage and abundant fruit crops for many years. Protecting your genip tree from problems is worthwhile to ensure maximum health, productivity, and longevity.
