In areas with cold winters, you can start the germination process indoors and transplant the seedling when conditions are optimal.
How to germinate an avocado seed step by step
- Remove the seed or pit of the avocado you just ate, taking care not to damage its outer brown layer.
- clean it thoroughly with water, removing any remaining pulp.
- Insert three or four toothpicks equidistantly so that they act as a support and keep the base submerged in water when placed on the edge of a glass.
- Fill the glass with water making sure the bottom of the seed is in contact with the liquid.
- Place the glass in a warm place with plenty of natural light., preferably next to a window, avoiding the direct sun exposure if the temperature is very high.
- Keep the water clean changing it every few days to prevent the growth of bacteria or mold.
- En 2-8 weeksIt's common to see the seed crack and the first root appear. Later, the aerial shoot will emerge. Before the root grows more than 10 cm, you can plan to transplant.
Throughout this stage, the humidity is key And the seed should never be completely dry. Patience is key: germination rates can vary depending on the variety and ambient temperature.
Land preparation and soil needs
The avocado tree is demanding with the soil type. Look for loose, deep substrates, with excellent drainage and rich in organic matter. To absorb nutrients well, The soil pH should be between 5 and 7 (slightly acidic to neutral). If your soil is clayey or waterlogged easily, mix sand, perlite, and compost to loosen it. Remove large stones or debris and dig a hole at least twice the diameter of the plant's root ball or root ball.
It is advisable to place a layer of sewer system with gravel or expanded clay at the bottom of the hole to prevent water retention.
How to plant avocado in the garden
- Gently remove the seedling when its stem measures between 15 and 20 cm and has several healthy leaves.
- dig a hole in the final location of your garden (at least 1 meter away if you plant more than one), twice as large as the root system.
- Place the plant straight shape, leaving the upper part of the bone visible if it is still attached.
- Fill the hole with a mixture of rich soil and compost, pressing gently to eliminate air pockets.
- Water abundantly after planting without flooding the soil.
- You can add a light coating of mulch to retain moisture and protect the roots from the sun.
Choose an area sunny, sheltered from the wind and where the tree can receive at least six hours of sunlight daily. If your climate is very dry, provide additional protection during early development with a shade cloth or natural barrier.
Essential care for avocados in the garden
- Irrigation: Keep the soil constantly moist, especially during hot or dry periods, but avoid waterlogging at all costsDrip irrigation is ideal for controlling the amount without saturating the soil.
- Subscriber: Avocado responds well to fertilizers rich in nitrogen, phosphorus, potassium and magnesiumFertilize in early spring and summer with specific products for fruit trees or with organic fertilizers such as mature compost.
- Pruning: It doesn't require extensive pruning, but it's a good idea to remove dead, damaged, or vertically growing branches. Perform formative pruning in the first few years to strengthen the tree and encourage lateral growth. Use light topping to promote more robust growth.
- Protection against pests and diseases: Control mealybugs, crystal mites, and scale insects with natural solutions such as potassium soap or neem oil. Monitor for mold growth and remove dead leaves regularly to prevent the spread of disease.
Remember that the avocado is slow growing and can take several years to bear its first fruits when grown from seed.
Planting avocado in a pot: Is it possible?
The avocado can develop in large pots (minimum 30-40 cm in diameter and 5 liters) during its first few years. This is ideal for areas at risk of frost or with limited garden space. It's essential to use a light, organic-rich substrate, ensuring good drainage.
Replenish the soil every year and repot when you notice roots emerging from the drainage holes. When the plant grows over 1 meter tall, you can move it to the garden or graft it from a tree that's already bearing fruit to accelerate production.
Grafting avocado trees: Advantages and techniques
If you want to get the fruits earlier and ensure a productive variety, performs a graft when the tree exceeds 80-90 cm in height. The most common method is the T-graft, which is more effective for ensuring quality and rapid production.
- Make a T-shaped incision in the stem about 30 cm from the ground.
- Carefully lift the bark and insert a healthy bud from a producing tree.
- Secure the joint with elastic bands and protect with a bandage or breathable mesh until it heals.
After a few weeks, the bud and the parent plant will merge. Remove the ties and maintain regular pruning to encourage budding of the graft. This can significantly advance fruiting compared to plants grown from seed.
Common mistakes and how to prevent them
- Excess watering: One of the most common problems that can lead to rot and fungus. Check the condition of the substrate before watering.
- Poor drainage: It is essential to prepare the soil or pot well, avoiding water accumulation.
- Pests: Chinch bugs, borers, and mealybugs can affect growth. Use organic solutions like neem oil and remove affected branches, leaves, or fruit.
- Poor fertilizer: Nutrient deficiencies cause yellow leaves and small fruit. Apply complete fertilizers during the growing season.
Additional tips for success
- Protection: Use stakes to protect the young tree from strong winds.
- Initial shadow: Shade seedlings during the hottest days to prevent sunburn.
- Patience: Avocado requires consistency. Some trees can take several years to bear fruit, especially if they haven't been grafted.
