How to Grow Avocado from Seed (2 Easy Ways!)
2 easy ways to grow avocado tree from seed in soil or water, better than toothpicks method! Best tips on germination, indoor & outdoor planting, & more!
We have all seen lovely photos of avocado seeds on toothpicks over a jar of water. The truth is, the toothpick method is not as great as it looks, and many have ended up with their avocado pits rotted or shriveled.
As plant lovers living in Southern California – the biggest avocado growing region in the US, we have grown many avocado plants from seeds and learned lots of tips and tricks along the way.
Now it’s time to share with you how easy it is to grow your own avocado seed into a beautiful and unique indoor plant, or a fruit bearing tree! Let’s start with a question that everyone asks 🙂

Can you grow your own avocado tree that bears fruit from just a seed?
Avocado trees grown commercially or sold in nurseries are grafted to ensure the reliable varieties. The fruits can be a little or a lot different (either superior or inferior ) than the original avocado from which you got the seed.
It is important to know the top and bottom of an avocado seed.
When we grow an avocado seed, the roots always come out of the bottom and the stems come out of the top of seed pit. Therefore we want to plant the seed with the top part pointing up.
The top of an avocado seed has a pointed shape, like the top of the avocado fruit. The bottom of the seed is flat.
Helpful tip: avocado seeds that started to crack are great for planting, because roots have already started to develop!
How to sprout and grow avocado seed in water
I love this method because it is so much fun to watch beautiful avocado trees growing from sprouted seeds in jars of water! If you just want some pretty indoor plants to decorate your home, you will really enjoy this technique.
A big thank you to Brad on YouTube for the great video tutorial!
First, let’s look at a better alternative on how to sprout an avocado seed without toothpicks. The problem is actually not the toothpicks, but the timing!
Clean the avocado seeds and peel off as much of the skin as possible. This reduces the chance of the seeds molding while germinating.
Wrap the seeds loosely in damp paper towel, and place them in a plastic bag or a container with lid.
Check on the pits once a week. If the paper towel smells or look slimy, wash the seeds, the plastic bag or container , and change to a clean piece of paper towel.
Once the avocado seeds crack, look for tiny white roots that sprout from the bottom of each seed, and be careful not to damage the roots. When the roots grow and sprout beyond the bottom of the seeds, it’s time to start growing them in water.
This stage can take 1-2 months. It’s a good idea to start with more seeds than you need, and just keep the first sprouted seeds, because some seeds take much longer time to sprout, for no reason! You can also plant the cracked or sprouted avocado seeds in soil at this stage, like mentioned in previous method.
At this point, you can actually use tooth picks or something more unique! There are avocado tree growing kits you can get on Amazon here. You can also use recycled plastic water bottles to make some!
Cut off the top portion of a plastic water bottle without the lid, and place it on top of a glass jar as shown. Put a sprouted avocado seed inside this half sphere with roots pointing down. Add water until the bottom half of the seed is submerged in water.
Always keep the roots submerged in water as it grows. After a couple more weeks, stems and leaves will start growing out of the avocado seed. keep the plants in a very bright place, but out of direct sunlight.
Although avocado plants love direct sunlight when growing in soil, we need to keep them out of direct sunlight when growing avocado plants in water, because algae will grow when water is exposed to direct sun.
Here are some of our avocado seedlings growing in water at different stages. All we do is replenishing the water once a week, and add a drop of all purpose liquid fertilizer once a month.
The water stays clean and clear usually. If you occasionally see signs of algae, clean the jar and change water.
Again, the only difference when you grow avocado indoors in soil vs in water is that avocado plants growing in jars of water need to be away from direct sun, because algae can grow in water exposed to sunlight. 🙂
Another tip: If you eat an avocado but are not ready to plant the seed right away, you can wash avocado pits clean and keep them in a jar of water for several weeks, so they don’t dry out.
How to plant an avocado seed in soil
While it is fun to grow avocado seeds in soil, if you want a bigger avocado tree as indoor plant or a garden tree, you will want to plant them in soil, which will allow them to grow to much bigger size.
In warmer weather, all you really need to do is to plant some avocado seeds in soil either in the garden or in a pot, keep them watered. Avocado seedlings will grow in 1 to 3 months. We can’t even count how many avocado trees have grown from pits in our garden compost!
You can started with the seed straight from an avocado, or sprouted seeds, or avocado plants growing in water like we just did! Some gardeners like to soak or sprout their avocado seeds in plastic bag first before planting them in soil. This way they know the seeds with roots will keep growing.
When planting avocado seeds in pots, choose a well drained potting mix with slow release fertilizer. My favorite potting mix is kellogg raised bed & potting soil mix which you can find at Home Depot.
Place the pits in soil at a depth about equal to the seed, with the top part of the seed pointing up, and cover with soil to the top tip.
Avocados like well drained soil and direct sunlight.
Keep the soil damp but never let the soil get soggy. Keep the pot in a warm sunny place. Like mentioned earlier, seeds with cracks will be the first to germinate and leaf out. 🙂
If you live in a warm climate, your avocado tree can grow into a 40′ tall big tree in the garden.
How long does it take for avocado plant to fruit?
When we plant an avocado seed pit, the tree seedling may take 5 to 10+ years to bear fruits.
Can you grow avocado trees indoors?
Avocado trees can be beautiful as indoor plants. Although they may not fruit when growing indoors in a pot, due to limitations on size & pollination requirements. Use these tips for indoor plant Fiddle Leaf Fig care to care for your avocado plants!
Avocados are subtropical trees, so most of them do not like temperatures below 32F. The cold hardy varieties such as Fuerte or Bacon will grow outside down to USDA cold hardiness zone 8. You can also grow potted avocado trees in a greenhouse in colder climates.

Happy growing! 🙂
I planted a seed in soil and it got about a foot high and very lush then it split into two sides but I don’t know if I should cut one off if so witch side?
hi Donna! i would leave the split seeds and not try to break off anything in case the stem get damaged. the seed will eventually shrivel and fall off. 🙂
I placed seed wrapped in damp paper towel in snack size ziplock baggie. Should I place this on our window sill that gets indirect sunlight or do you have suggestion for a better place? Also I poked it with toothpicks before seeing your post. I removed the toothpicks but wonder if the 3 holes damaged the seed?
Thank you for your post and looking forward to your reply.
hi Joni! seeds only need light after germination. i think it’s best to put in a container than a flat bag because it’s easier to see the roots and plant the seeds later! 🙂
I’m thinking about growing one in a hydroponic garden indoors in Michigan. Question is how long before I see fruit? And does it need to be pollinated and if so what does it need? Meaning besides bees can this be done manually and does there need to be more than one plant?
-thanks
hi Mike! there are “type A & B” avocados, an the trees are more productive (not required) if you have one of each at least. in an indoor environment, you may need hand pollination! 🙂
I have an avocado seed that is about 6 inches tall.
I started it in water and transferred it to the soil once it started to sprout.
I currently have the top half of the seed sticking out from the top of the soil.
Is there ever a time when I should completely bury the seed or should I always
have it partially sticking out?
I am also wondering what to do with the see when the plant gets larger and
needs to be transferred to an even larger pot.
Thank you so much for this wonderful site…..SO much information.
Meant to say that I have an avovado PLANT that is six inches tall, not a SEED that is six inches tall.
hi AJ! i have done it both ways, burying the seed or leaving it at the soil level. they both work! i would just leave the seed at soil top at this point, and keep the seed there when you re-pot! happy growing! 🙂
Once the seed has sprouted by water method (about 4 to 5″ high) should I transplant to soil or keep it in the water?
Thanks!
hi Michelle, the plant can stay in water for long time, but it grows much faster and stronger in soil. you can plant it in soil at this point 🙂
Thanks so much for your quick reply! I’m going to plant it and hope it keeps thriving. This has been a fun project to do with my grandkids! Thanks!
Hello,
I have been growing my plant from a seed and it is about 14″ tall. I have it in soil, but it is not getting bushy. It is just growing taller. It has lost some leaves. Should I cut it back to 6 inches?
hi sharon! i would let it grow more. if you want to cut it to encourage branching, i would do it in spring or summer when it’s actively growing! 🙂
Love your site and instructions for growing avocados from seed. I have a question, actually, and a bit of a challenge that I haven’t seen addressed anywhere online so far. I have been growing avocado plants by germinating them in soil for a few years. My oldest plants are 3 years old. Here’s the rub: I just put the pits into existing pots with other non-avocado plants: as an experiment I put them in among all kinds of other plants in various pots, all in the same window but only had success with one big pot…and now I have 18 germinated pits in one pot! It became a bit of a game to see if they’d keep germinating and they basically ALL did! Not only did they germinate but they are doing so quickly, some sending up shoots in less than a week! But my dilemma is, the roots don’t like to be disturbed so I don’t believe I can transplant any of them. Now I have an avocado jungle and obviously they are all vying for light and space. I do not know what conditions exist in this pot to have this happen….So I do not know how to emulate it for transplanting and as I said, I tried seeds in other pots and no germination occurred. Has anyone else encountered a situation similar to this? T
hi Suze! i had a 5 gallon pot with 6 avocado seeds growing, and i was able to separate them and transplant them into other pots with no problem. i think you can keep all your plants in one pot, or separate a few out to test so you still have many plants in the original pot to be safe. 🙂 just try to keep as much roots as possible on each plant, and keep the transplants in shade for 2-3 weeks to adapt.
Yes! Thanks for recommending the water bottle method. I have tons of little mason jars and didn’t want to mess with toothpicks. My little avocado seed has its root startong to peek but not quite ready for the water. This will be great to use and I may just start a few more seeds now. They are pretty and I’m in AZ so the sun always shines here.
hi Nikki! if you can set the bottom of the seed in water where the root is touching the water, i would go for it. happy growing!! 🙂
Hi,
Thanks for this. I opened an avocado and discovered it has started sprouted but noticed the tip of the root at the bottom is darkened, (looks rottened) will it germinate if I grow in water jars?
hi Ruth! it’s very possible! just keep the water clean for the first week or 2. the root may still grow! 🙂
Thanks so much for your advice. Glad to let you know that I tried both, the glass jar and the one for pots and they are doing well. I can see the roots for the one in glass jar, also the pits are divided showing sprouts. Same for the one in the pot.
thank you Ruth for the update! glad it worked! 🙂
I’ll try these methods, and see how it goes!! It looks a lot easier than the toothpick method!
someone on instagram just shared her success with us this week! 🙂 good luck and have fun!
We have always wanted to try growing avocado pits. Just followed your tutorial and started a few seeds with our kids. Very excited to see the roots coming out! 🙂
Wow this is so pretty! I am saving some avocado pits to do this!
How do you get the skin off the pit? I have tried, but the skin does not want to come off.
Thanks
hi maddy! it’s not required, just make the seeds a little less likely to get moldy. soaking the seeds helps to loosen the skin 🙂
I love avocado! Once my son asked to help him grow a seed, but unfortunately, nothing came of it. I’ll try on your guide, thanks!
I wanted to grow Avocado as indoor plant. Today I kept the seed in the glass jar adopting the toothpick method.. Since it is a very long time consuming process, I will wait for some to response. Thank you.
Great tutorial. Wonderful pictures. Great instructions. I will try the soil method next time. MUCH better than the toothpick method. Thanks for sharing! Be safe.
thank you Carol! best wishes, and happy growing! 🙂
Well done post. Your water bottle idea looks a LOT easier than fiddling around with toothpicks!
thank you so much Kathy! 🙂 have a wonderful september!! xx
