After removing the pit from an avocado, don't throw it away. Wash the pit. Stick three toothpicks around the pointy upper third of the pit. Then fill up a jar water and rest the avocado pit on the rim with the large portion of the pit in the water and small portion above water. After five days, place the jar in a spot where the pit can receive sunlight. It won't be long before you see roots appears and leaves sprout. Once you have a healthy system of roots and several leaves you can transplant to potting soil. Water once a week.

Avocadoes make excellent trees, I just stick mine on nails or toothpicks, three of them, and point them towards the sky and wait. They all have their own time. Some of them never grew, some of them did.
I never pinch mine back either.

They are so wonderful! I have had my most recent plant since last spring, while it was still cold. I also put tomato seeds in the soil of my other potted plants. I have become kind of tomato crazy, I love them! After they sprout, I move them to another plant holder. They kind of keep the soil happy and the avocado plant seems to love having plants growing around it.

Mine is now three feet tall, and I talk to it each day. They like it a lot, and they like being in a pot which is big enough so they don't become pot bound. OK I admit it, I occasionally name mine.

Hi everyone, you should all try starting the pits in soil. I have been growing these things for years and soil makes them a far more solid and sturdy plant. Just tuck it about 3/4 of the way into some good potting soil pointy side up and keep moist. I always use bottled water because they don't seem to like the chlorine that's in tap water. Have fun!

My mom has an avocado tree in her back yard that she started from a pit, and now she gets so many avocados she hands them out to all her neighbors. Of course she lives in the California Bay area, so that may help.

If you were lucky enough to have your avocado seed sprout, then you will now need to plant it. Choose a pot that is big enough that you won't have to repot it right away. Use a potting soil that is somewhat sandy, to allow for good drainage.


Add some soil to the pot and then test fit your seed, making sure that the top half of the seed will remain above the soil. Be very careful not to break the roots.

You can just cut or break off the toothpicks. Then gently work soil in and around the root, making sure that the seed is well support underneath. Then finish filling up the pot, leaving the top half of the seed sticking out. You may need to stake your plant up.

Your plant will do best if you mist it regularly. When watering your avocado plant, allow the soil to dry out slightly between waterings. Place your plant in a warm location, out of direct sun light. Pinch back growth as necessary. Wait a few months before fertilizing.

Growing an avocado plant from the pit is a great project for kids to do. It is so easy. Our kids love to eat avocados and really wanted to try sprouting one. We have tried to sprout one before and it didn't work. This time it grew and the kids were so excited! Now we need to transfer it into a pot. :)

Here's a fun summer activity for the kids to enjoy and a rewarding way to recycle the left-over avocado seeds.

  1. Wash the seed and suspend it (broad end down) over a water-filled glass using 3 toothpicks. The water should cover about an inch of the seed.

  2. Place the glass in a warm location, out of direct sunlight. A mature seed will crack as roots and stem sprout in about 2 to 6 weeks.

  3. When a stem grows to six or seven inches, cut it back to about three inches.

  4. When the roots are thick and the stem has leafed out again, plant it in a rich humus soil, leaving the seed half exposed. Use a terra cotta pot with a 10-1/2 diameter.

  5. Water the avocado plant generously, but let it dry out somewhat between watering.

I was wondering if anyone knows on how too start an Avocado Tree from a seed. Please Help

Tam, Avocado pits can be germinated in either soil or water. Pits germinated in soil are said to be hardier in the long run. Personally, I think it's more fun to watch them sprout in water.

Starting them in soil: Soak the pit in water for 24 hours prior to planting. Place the pit (broad end down) into a pot filled with a moist, soil-less mix. Bury the pit so it's about 1/2 inch below the surface of the soil and set the pot in a warm place. Keep the soil moist, but not wet. To keep the pot humid and to conserve moisture, you may want to cover it with plastic wrap. This isn't necessary, and if you do it, make sure you keep your eye out for signs of mold or rotting.

Starting them in water: Insert three toothpicks into the bottom 1/3 of the pit to create a tripod that will support the pit when suspended over a jar filled with water. Rest the pit over the mouth of the jar so that the base of the pit is submerged in 1/2 inch of water. Add fresh water daily to maintain the level of the water. Eventually, the pit will crack and roots will appear, followed by one or more stems. If multiple stems emerge, leave them all intact.

Transplanting seedlings: After the stem(s) grows to 6 inches, cut it back to 3 inches to encourage bushy growth. At this point, you'll need to transplant the seedling into soil within a few weeks of cutting it back. If you germinated the pit in water, don't worry about removing the toothpicks-just cut them off with a scissors before planting. When transplanting, be very careful to avoid injuring the new roots. Use a large pot filled with a light, sandy soil.

Once transplanted, place your avocado seedling in a warm, bright location, out of direct sunlight. Keep the air around it humid by misting it frequently (especially in the winter), but let it dry out slightly between each watering. Let your new transplant settle in for several months before giving it any fertilizer. It will be getting plenty of nutrients in the new soil. As your avocado grows, you may find it needs some staking or support. You can keep growth in check by pinching and pruning back as necessary.

Good Luck!

It is that time of year when I get the wonderful spring fever and want to start growing things. Here are a batch of avocado pits sitting in their own pods made from foam egg crates.

I have several avocado seeds ready for the Path Garden. There are already 4-6 tiny trees from seeds from a couple of years ago.

I took the pit right from the avocado and planted it with my tropical plant. It is flourishing so far. I guess I need to mist it. I will stake it up if it seems to lean but so far it hasn't.

I used some material from the bag our potatoes came in and then a piece of plastic grocery bag tied around the potato bag over the jar. The avocado pit was pushed far enough down into the jar to be able to start this way.

I have been growing an avocado pit suspended in a glass of water for about 8 weeks now. The pit has split and I see the beginning of a root, but now fine white hairs can be seen on the bottom of the pit. Does this happen? or is this algae? Has this happened to anyone else? I have been changing the water once a week.
