Steps for growing an avocado plant from seed
What You Will Need:
  • An avocado pit
  • A glass jar
  • Three toothpicks
  • Potting soil
  • A pot with drainage holes
Instructions:
  1. Wash and dry the avocado pit. Remove any remaining flesh from the pit.
  2. Insert three toothpicks into the pit, evenly spaced around the circumference. The toothpicks should be inserted about halfway into the pit.
  3. Suspend the pit in a glass jar of water. The bottom third of the pit should be submerged in water.
  4. Place the jar in a warm, sunny spot. Change the water every few days to keep it fresh.
  5. After 2-6 weeks, a stem and roots should start to sprout from the pit. Once the stem is a few inches tall, you can plant the pit in a pot of potting soil.
  6. Place the pot in a sunny spot and water it regularly. The soil should be kept moist but not soggy.

Plastic Bag Method

You can also start your seed in a plastic bag, instead of a glass of water. Simply wrap a clean avocado seed in a moist paper towel. Place the wrapped seed in a plastic bag, Close the bag, but don’t seal it tightly; leave some air circulation. Store the bag in a warm place and monitor for growth.

Once the root is about 2 inches long, you can plant the germinated seed in a pot filled with well-draining potting mix. Place the seed half-buried in the soil, with the root pointing downwards. Then continue with our avocado plant care guide.

Additional Growing Tips

  • Use a ripe avocado pit for best results.
  • Removing the skin from an avocado seed is not strictly necessary for growing an avocado plant, but can help with faster, easier germination.
  • Be patient! It can take several weeks for the pit to sprout.

Producing Fruit from an Avocado Plant

Most avocado houseplants will not produce fruit. It’s possible that they can, but it is not as common as with avocado trees grown outdoors. The main factors that affect fruit production in avocado houseplants are:

  1. Variety: Some avocado varieties are more likely to fruit indoors than others. Choose a variety known for its ability to fruit indoors, such as ‘Hass’, ‘Wurtz’, or ‘Holiday’.
  2. Pollination: Avocado plants need to be pollinated to produce fruit. If you have multiple avocado houseplants, you can try hand-pollination using a cotton swab.
  3. Conditions: Avocado houseplants need the right conditions to fruit, including bright, indirect light, warm temperatures, and moderate to high humidity.
  4. Age: Avocado houseplants may not fruit until they are several years old. Be patient and give your plant the time it needs to mature.

So while an indoor avocado plant will usually never fruit, they can still grow into beautiful houseplants.

Caring for an Avocado Plant

Once the seed grows into a full plant, you’ll need to know how to care for it. The care for an avocado plant involves providing the right conditions for it to grow and ensuring it receives adequate water, light, soil, temperature, and humidity. Here’s a comprehensive care guide for your indoor avocado houseplant:

Light

Avocado plants thrive in bright, indirect sunlight. Avoid direct sunlight, as it can scorch their leaves. A sunny window near an east- or south-facing wall is ideal. If your plant starts to look leggy or its leaves turn pale, it may not be getting enough light.

Water

Avocado plants require consistent moisture, but avoid overwatering. Allow the soil to dry out slightly between waterings, and then water deeply. Aim to keep the soil moist but not soggy. Overwatering can lead to root rot, while underwatering can cause leaves to wilt and drop.

Soil

Avocado plants thrive in well-draining, rich soil with a slightly acidic pH of 6.0 to 7.0. You can use a commercial potting mix specifically designed for avocados or create your own by mixing equal parts potting soil, perlite, and peat moss.

Temperature

Avocado plants prefer warm temperatures, ideally between 60 and 80 degrees Fahrenheit. Protect them from cold drafts and sudden temperature fluctuations. If you live in a colder climate, bring your avocado plant indoors during the winter months.

Humidity

Avocado plants prefer moderate to high humidity levels. If your home air is dry, consider using a humidifier near your plant. You can also mist the leaves regularly with water to increase humidity.

Fertilizing

During the growing season (spring and summer), fertilize your avocado plant every 4-6 weeks with a balanced liquid fertilizer diluted to half strength. Avoid overfertilizing, as this can damage the roots.

Pruning

Avocado plants benefit from pruning to maintain their shape and encourage new growth. Prune in the spring or summer, removing any dead, damaged, or diseased branches. You can also trim the ends of healthy branches to promote bushier growth.

Re-potting

As your avocado plant grows, it may need to be re-potted to accommodate its expanding root system. Signs that your plant needs re-potting include roots growing out of the drainage holes, water draining out too quickly, or the plant tipping over easily. Choose a pot that is 1-2 inches larger in diameter than the current pot.

Pests and Diseases

Avocado plants can be susceptible to pests like spider mites, mealybugs, and aphids. Inspect your plant regularly for signs of pests and treat them promptly with insecticidal soap or neem oil.

Fungal diseases can also affect avocado plants, often caused by overwatering or poor drainage. Ensure your plant has good air circulation and avoid overwatering to minimize the risk of fungal diseases.

More Avocado Plant Care Tips

Here are a few additional tips when caring for and trying to grow your avocado plant:

  • If the leaves on your plant start to turn brown, it may be getting too much sunlight. Move it to a shadier spot.
  • If the leaves on your plant start to wilt, it may not be getting enough water. Water it more often.
  • Keep out of reach of pets, as avocado plants are toxic.
  • Avocado plants are not frost-hardy, so bring them indoors during cold winters.
