How to Plant Avocado Seeds in Water

Before you toss out those avocado seeds after making a batch of guacamole, consider using one or more to grow an avocado plant in water. This is a popular and simple project for school children. Watching the seed spout and grow into a lovely green plant is a rewarding nature project. Eventually the seed can be planted in soil.

Remove the avocado seed from the fruit and rinse in water.

Hold the avocado seed so that the pointy end is up and the curved end is at the bottom. The pointed end will be referred to as the top of the avocado seed, and the curved end as its bottom.

  • Remove the avocado seed from the fruit and rinse in water.

Insert a toothpick on the side of the avocado seed, half way between its top and bottom.

Rotate the avocado seed a third of the way around and insert the second toothpick, half way between its top and bottom.

Rotate the avocado seed another third of the way around and insert the third toothpick, half way between its top and bottom. There should now be three toothpicks, equally spaced, along the center of the avocado seed.

Fill the glass with water.

Set the avocado seed in the water with the pointy side up. The lower half of the avocado seed should be submerged in water and the toothpicks should be hanging over the rim of the glass, holding the avocado seed in place so that it does not fall into the glass.

Set the glass in a sunny window and keep the bottom half of the avocado seed in water at all times.

Plant Avocado Seeds In Water

Rinse the avocado seeds in lukewarm tap water, and remove avocado residue from each seed's surface. Push four toothpicks into each seed, spacing them at equal distances around the seed's middle. Fill a water glass with lukewarm water to within 2 inches of its rim. Set one avocado seed in the glass with the seed's wide end, or bottom, resting in the water and the toothpicks resting on the glass rim. Repeat the procedure for each avocado seed, providing each seed with its own water glass. Place the glasses in a warm area that receives bright but indirect sunlight, such as near a window. Replenish the water in the glasses as needed to maintain the water level. Avocado seeds typically take from three weeks to two months to sprout.
