The next time you eat an avocado or use one in a recipe, save the stone or pit. Planting your own avocado tree is fun and easy. It is a perfect task for all ages — for the garden, for indoors, and also makes a great project for class or at home! This method will yield a tree that flowers, but not one that bears fruit. If you want to grow an avocado tree for fruit, it is best to purchase a grafted tree from a nursery.

Things You Should Know

  • Stick toothpicks into a clean avocado pit and submerge 1 inch (2 cm) into a glass of water. Set the cup in a sunny area and change the water every 1-2 days.
  • Plant the seed in a 8-10 in (20-25 cm) pot full of enriched soil once the sprout is 6-7 in (15-18 cm) tall. Water it regularly to keep the soil moist.
  • Alternatively, dig a small hole in the ground and place a clean avocado pit inside with the pointed end face up. Keep the soil moist with regular waterings.

Preparing the Seed

  1. Cut into the avocado carefully, so as not to injure the pit, which is in the fruit's center. You can do this by scoring the skin/fruit about ½ an inch (1.3 cm) deep all the way around the outside, and then twisting the two halves in opposite directions to open it. Carefully remove the pit and set it aside.
    • So that you don’t waste the fruit, use the avocado meat to create the tasty dip/topping known as guacamole .
  2. Wash the avocado pit gently to remove all the flesh. Use warm water and your hands, and avoid using soap. Be careful not to remove the seed cover which is light brown, as this may destroy the pit and make it less likely to grow.

  3. Holding the pit "narrow" (pointed) side up, stick four toothpicks into the middle section at even intervals, just enough to give a firm hold. This will allow you to balance the pit on the inside of a cup, without completely inserting it into the cup.
    • The pit should sit in about 1 inch of water, so keep this in mind when inserting your toothpicks.
  4. Add some water to a small, slender container (preferably glass) until it reaches the top rim. Your container's opening should be wide enough to accommodate the full width of the avocado pit easily; however, make sure that it is not too wide, otherwise the toothpicks will not be able to reach and the pit will fall in.
  5. The toothpicks should sit on the rim of the container, leaving 1 inch of the pit only submerged in the water. Make sure the pointed end is up and the rounded end is in the water, otherwise your avocado will not grow.
  6. Set the avocado-topped container in a temperate, undisturbed place — near a window or any other well-lit area to begin rooting and the growth process.
  7. Do this to ensure that contaminants (i.e. mold, bacteria, fermentation, etc.) do not hinder the avocado's sprouting process. Ensure the base of the avocado always remains moist and submerged in water.
  8. Over the next two to three weeks, the avocado's brown outer layer will begin to dry out and wrinkle, eventually sloughing off. Soon after, the pit should begin to split open at the top and bottom. After three to four weeks, a taproot should begin to emerge at the base of the pit. [1]
  9. Take care not to disturb or injure the taproot. Continue to allow the avocado pit time to establish its roots. Soon, the avocado will sprout at the top, releasing an unfolding leaf-bud that will open and begin to grow a shoot bearing leaves.

Planting the Avocado Tree

  1. Avocado trees are very particular in terms of their ideal climate and growing conditions. Most of the time, avocado trees should be planted in a pot, and moved around to meet the changing weather. Avocado trees prefer a temperature of 60 – 85°F (15.6 – 29.4°C), and established trees can handle temps as low as 28°F (-2.2°C).
  2. Avocado trees can grow in soil at almost any pH level, but it must be low in saline and have plenty of drainage. The soil does not need to be heavily fertilized until after the tree is about 1 year old. At that point, you should conduct a soil test to find out what nutrients are available/lacking in your soil. You can then get fertility recommendations based on the nutrients found in your soil. [2]
    • You may want to use a 10-10-10 fertilizer twice a year to help the tree out. In general, you can use regular potting soil and add some rocks to the bottom of the pot to aid in draining excess water. [3]
  3. Use a 20 – 25 cm (7.8 – 9.8 inches) terracotta pot filled with enriched soil to 2 cm (.8 inches) below the top. A 50/50 blend of topsoil and coir (coconut fibre) usually works best, but make sure you check the soil where you're planting to ensure this is the right blend. Smooth and slightly pack the soil, adding more soil as needed. Once the soil is prepared, dig a narrow hole deep enough to accommodate your avocado's roots and pit.
  4. When the tree reaches 6-7 inches in height, prune it back to 3 inches. When leaves have re-grown, you are ready to plant. Remove the sprouted pit from the water container, and gently remove each of the toothpicks.
  5. Carefully bury the avocado pit in the soil such the top-half of pit shows above the surface of the soil. This ensures the base of the seedling trunk doesn't rot under the soil. Pack the soil lightly around the pit.
  6. Water your plant daily or enough to keep the soil moist. Avoid over-watering to the point the soil becomes muddy. If the leaves turn brown at the tips, the tree needs more water, while if the leaves turn yellow, the tree is getting too much water and needs to be permitted to dry out for a day or two.
  7. Continue to tend to your avocado plant regularly, and in a few years you will have an attractive and low-maintenance tree. Your family and friends will be impressed to know that you cultivated and grew your own tree from an avocado pit salvaged from your guacamole recipe .

Ground Growing

Some growers find that placing the seed in water to sprout it risks producing a long, leggy tree that fails to fruit. In this case, it is better to place the seed in the ground without soaking first.

  1. Cut the fruit flesh away from the seed. It is easiest to cut it the long way around.
  2. Whack it with a knife, then twist, and the seed will come out.
  3. this is the top of the seed.
  4. See the above method for plant positioning suggestions. Clear the sod or whatever else is there, in readiness for planting.
    • If possible, plant two trees, as these plants like company.
  5. Use your hands to mound up the loose soil around the seed. Do not stomp the dirt down with your foot as you may damage the seed this way.
  6. Fertilize after you see the plant above the ground. Do not do so sooner or the root system will fail to form properly. In about three to four years, expect fruit.
  7. They will not ripen on the tree. Remove and place inside a brown bag to ripen. They're ready to eat when soft.

    Avocado trees cannot self-pollinate. If you want to grow fruit, you will need two different types of trees planted together. A rule of thumb for spacing avocado tree is 20 feet between each tree.
  • Question
    My tree sprouted and is about 2 feet tall. Should I cut it back and cut the leaves off?

    It will help the tree if you cut the stem below the top two leaves. This will help your tree branch out.
  • Question
    How tall will the avocado tree get?
    Dvor
    Community Answer
    It depends on the variety, but it can be anywhere from 4.5 meters (about 15 feet) to 12 meters (about 40 feet). There are also dwarf avocado trees that generally range from 1-1.5 meters (4-5 feet) tall.

      Tips

      • It is also questionable whether two trees are required for cross-pollination. This is not necessarily the case. In at least some strains, the tree bears both male and female flowers and is self-pollinating. You may also graft from an existing fruit-bearing tree to your homegrown rootstock (tree grafting, however, is another process all unto itself).
      • Be patient. When you think it isn't going to grow suddenly it will look like someone stuck a stick in the soil. Don't pull out! That's your seedling growing! Sometimes it will grow 6 or 8 inches before you see any leaves.
      • During the winter or in cold climates, it is best to transfer the baby avocado tree into potting soil in a medium flowerpot rather than directly into the ground. Keep the plant in a sunny window and keep the soil moist but don't over-water.

      Warnings

      • An avocado tree grown from seed becomes very tall, unlike a grafted tree. Avocado branches are fragile and do not support any weight on them, so don't hang anything like a hammock from the tree branches as they will break off.
      • Low lighting and/or improper watering can also create weak stems and branches, which ultimately will cause the plant to collapse under its own weight.
      • Letting the pit's bottom tip dry out will most likely prevent the avocado from sprouting properly, if at all.
      • It can be difficult to get an avocado tree grown from a pit derived from an avocado purchased at a store to produce fruit. Though store Avocados are not genetically altered, it takes specific conditions to produce fruit. Do not expect any fruit from it.
      • Over-pruning (too much or too often) can stunt or stop leaf growth. After the first pruning, cut off only the very end leaf-buds on the stem and/or branches. For tree limbs and main stem trunk, pruning promotes both fuller branches and thicker, stronger leaves.
      • Keep your plant away from cold breezes, breezy doorways, and cold windowpanes. If your tree is potted, keep it indoors until the temperature rises. For young, ground-planted avocado trees and most potted avocado trees, cover the plants leaves completely with a blanket or heavy plastic during cold weather, at least until warmer weather prevails. Well-established avocado trees can often survive mild frosts and temperatures near freezing. The best bet: Always cover your tree when in doubt.
      • Not changing or adding water sufficiently to the sprouting avocado pit can allow contaminants to form in the water and/or on the roots. Molds, root rot, fungi, and fermenting water can quickly poison the entire plant. Keep the water fresh and at the proper level.
      • Until the tree is well-established in a pot, do not plant it directly in the ground. A strong plant root system with well-loosened ground soil make for a good outdoor planting situation.
      • Thin or spindly branches and stems make for a weak plant support foundation. Failure to prune often enough can create long, winding, weak branches and stems. Pruning allows the tree stem to thicken and grow more rigid.

      About This Article

      Article Summary X

      To plant an avocado tree, start by filling a pot with an even blend of topsoil and coconut fiber. Then, take the seed out of a fresh avocado and plant it in the pot so the thin end is sticking up above the soil. After you plant the avocado seed, water it thoroughly so the soil is moist. Avoid fertilizing the avocado seed until it sprouts or you could hurt the roots. While you wait for your avocado tree to sprout, water it every day or whenever the soil looks dry so it gets enough moisture.
