Often I’ve heard how amazed people are that I’ve had so much success growing avocado plants from seeds. I think it is because the old toothpick-over-water method is such a hit or miss.
So far I’ve had 95% success with sprouting avocado pits with the method I’m going to share today. I can’t take credit for coming up with it…who knows where it first started, but a number of blogger friends have shared variations of this with great success. So I gave it a try myself with a few small tweaks, and a few different sets of pits to experiment. Sure enough, it lived up to expectations, so I’m excited to continue to share the love!
Here’s how I successfully sprout avocado pits:
#1. Soak The Avocado Seeds Overnight
As soon as you remove the pit from the avocado, clean it and soak it in warm water overnight. If you aren’t on well water, use filtered or mineral water moving forward.
#2. Peel Away The Outside Husk
You probably won’t be able to peel all of the outside husk at once, but get as much as you can. Don’t worry, in the next few steps you’ll have opportunity for the husk to soften up and peel more away.
While this step is technically not required, occasionally a harder husk may prevent the root or shoot from growing properly. I had to remove the husk on a couple of my avocado pits because the root couldn’t penetrate it and grow straight out the bottom. It rerouted to grow out the side, which you don’t want. Give your avocado seed every advantage you can!
#3. Wrap In A Wet Paper Towel
Wrap each seed in a wet paper towel. It doesn’t have to be dripping wet, but it should be more than just a little moist, and use warm water.
#4. Place In An Airtight Plastic Container In a Dark Place
Place the wrapped avocado pits in an airtight plastic container, or a ziplock bag. Set it in a dark and warm or room-temperature location (or just make sure the location isn’t cool).
I put mine in a kitchen cabinet where I wouldn’t forget about it.
#5. Check Once A Week & Change Paper Towel
Check in on the status of your avocado seeds at least once a week, and rise them off so they don’t get mildewy. Swap out the old paper towel with a fresh wet paper towel weekly; this prevents it from drying out, or molding.
During these checks you should be able to peel the rest of the husk off the avocado (bit by bit), and eventually they should all split. That is usually an indication that a root is starting to form.
Leave it in that dark warm location until the root starts to protrude out the bottom. Don’t let the root get long otherwise it will grow bent. It should protrude just outside the seed…
#6. Place On A Jar of Water Once Rooted
Once the root is protruding from the avocado seed move it to a jar filled with filtered water if you are on public water, or buy mineral water to sprout your avo seeds. My well water is like magic super sauce when it comes to propagating. You can use the toothpick method to hold the avocado above the water at this point. Or get a jar with a mouth just wide enough for the avocado seed to sit atop, or use a prop cone like this one I bought here.
Don’t submerge the whole seed, but make sure the root is touching the water. In the next week or two you should see the root grow down into the water and even send out root offshoots.
Be sure to place your sprouted avocado seed in a bright spot (indirect sunlight) in your house for it to grow.
Helpful Care & Growth Tips
Once the roots are deep down in the water it is okay that part of the root is exposed to air. However be careful to not allow the water to evaporate over time.
It may take several more weeks before the shoots finally emerge and you get any leaves. But in the meantime rinse the roots and refill with fresh water if you start to see buildup on the roots. And move the seed to a taller jar once the roots start to hit the bottom. You don’t want to stifle root growth.
Typically it takes about 8 weeks to go from day one soaking the seed, to having roots and shoots with small leaflets. However some avo seeds are late bloomers while others burst on scene, but on average this is the approximate times my various sets of avocado plants have taken to grow.
- Soaking (Day 1)
- Seed splits and root is visible inside split (Week #2-3)
- Roots grow down into water and branch out (Week #3-5)
- Shoot starts to emerge and grows tall (Week #4-6)
- Shoot grow real leaves (Week #6-8)
- Nice sized leaves, established root system…you have a real plant! (Week #10)
Moving It To Soil + Plant Care
The seeds sprout, grow, and do well in water for quite a while. But once your plant starts to grow tall (about a foot), it will need the nutrients it can only get in soil. It will grow tall fast and get top heavy, but the stem/trunk will be skinny instead of hearty if you don’t transfer it to soil before it grows too tall.
Use potting soil, and a pot with drainage holes in the bottom plus a drip tray. Avocado plants can end up with root rot and die if the roots sit in moisture for too long. Water it deeply and allow the top 2 inches of soil dry out between waterings.
Make sure your avocado plant gets plenty of indirect sunlight. Too much direct sun may burn the leaves, especially while it is young and just getting established. Avocado plants like the sun, the warmth, even humidity. It also needs to be fertilized periodically, but the frequency depends on the type of fertilizer…follow instructions.
And finally don’t forget to transplant into a bigger pot if you want it to grow tall and bushy. Once it is a few feet tall and looks like a regular tree, you can trim the top to encourage it to grow bushier and branch out.
Will It Ever Bear Fruit? / Why Grow It?
Let’s be honest, your chances of ever bearing quality avocados from your little seed sprouted tree aren’t very high. Avocado trees need other companion avocado trees in order to pollinate (so plan to grow more than one). And even if they do, it could take upwards of 15+ years to fruit and the produce might not be the best quality. Typically fruit bearing avocado trees produced from a graft are your best bet to get a ‘real’ plant that produces good fruit within a couple years. I bought two grafted avocado trees online, and it would have produced fruit in a year or two if I hadn’t killed it from over-watering. I was a rookie back then…
Alternatively you could use your seed-sprouted avocado tree as a base and actually graft a piece of a fruit bearing avocado branch onto it once it is big…but that requires a lot more knowledge and effort than simply buying a ready-to-go avocado tree.
So why grow it? Well I consider my seeded avocado plants a free houseplant. Think of it no differently than you would think of a Fiddle Leaf Fig tree. This variety of fig tree will never produce actual figs, and it’s not the easiest plant to care for, yet we love it in our decor as a sought after houseplant. So if my avocado tree does well over the years and I’m lucky to get fruit from it before my kids have kids, great! Otherwise I will likely buy a more mature tree for the purpose of gaining produce, and enjoy these seed sprouted ones as likely ornamental.

First time trying to germinate avocado this year and worked. Some just take mire than couple months. Question, one of my seed has no roots yet but starting to grow plant inside the seed. You can seed leaves forming inside the split seed. What should I do? It is still wrapping with wet paper towel on top of warm spot in the house. Thank you.
My avocado has grown a really big long shoot and it has started to grow a stem at the top but it looks brown and doesn’t seem to be getting any bigger. Is it dead?
Hi! So I’m currently trying to germinate a handful of seeds and I’m at the point where most of the pits are cracked. I noticed that there are roots that are growing!! But I’m seeing that the roots are spiraling back into the pits (one around the center too!). What should I do at this point? Do I want to put them into jars of water or soil? I was hoping to wait until the roots are much longer like the pictures, but it seems like they’re just growing in circles and not straight.
Go ahead and place them with the seed just barely touching the water. The root will be drawn down to the water as it grows. I’ve had that happen a couple times, it still grew just fine! Good luck!
Omg I’m so excited. I put 2 Avocado seeds in the dark like you said. Today they are spouting.
In the last 5 yrs I’ve tried the toothpick only method. I never got 1 to spout. That’s a lot of failures. I found your posting and first time it worked.
Thank you so much. I will do the next process and see what happens.

I’m so happy to hear that!! Woohoo!
How much soil space do plants need? The roots of mine all grew really tall in the wine bottles I had them in.
Definitely choose a planter the roots can reach all the way to the bottom of. While you could start in a smaller container, you’ll eventually just have to move them as they grow bigger. It’s just easier to start in a big enough container.
On a whilm, I put an avocado seed into a ziplock bag. I added about a half cup of water from my sink. I then zipped the bag up and placed it on my window sill (indirect lite). That was about 2 months r less ago. The plant is now about 6 r 7 inches tall within the bag. It has many branches beginning to grow & the top has green leaves that haven’t opened yet. I never added anymore water bc it still has enuff n the bag. I don’t know where it’s getting it’s oxygen from bc I never opened its small ziplock bag. So what do I do now? I’ve never grown a avocado plant before. Especially like this. Please enlighten! I look fwd to ur reply.
We have a 12 inch high plant in soil, in the house and doing well BUT it has 3 stems out of the stii partly buried seed. Should we split and get 3 plants/potential trees OR is that likely to impede or even halt the growth, acknowledging that the purpose of growing from the seed is most likely ornamental indoors. Unless we leave to our kids in our wills ? !!!
Oh wow, 3 stems! In my experience, the avocado plant is a bit finnicky when young. Splitting it might result in killing it. If it was me, I wouldn’t. Not to say it isn’t possible…
Hello
Tnx for the toturial
My seeds have changed color to a dark brown and grey, the brown color also transfers to the paper towels
Does this mean they’ve gone bad?
I’ve had a couple that turned a brownish color that still sprouted. It’s hard for me to tell without seeing it. It shouldn’t be soft, moldy, or smell bad.
I’m normally a black thumb, but I’ve been successful with this tutorial! How large of a pot should I plant this in? I’m a lost wanna be gardener.
What type/mix of soil do you use for planting? I have many baby plants in various stages thanks to your tutorial!
Nothing special, just regular potting soil…
How deep do I plant the seed once I put it in soil? Thanks!!
I leave the top of the seed poking part way out of the ground.
Hi, so before I get a chance to putt in water my root grew fasted than I expect and is now bent growing in the opposite direction than it started. Is there anything I can do to recover from this?
It’s admittedly hard to recover from, but you can try! Just break off the bent piece of root, put the pit suspended in water so that the remaining root is ‘just’ touching it. It may grow, but it also might be easier to just start over.
Thanks so much!
If the acocado seed has been sitting out for awhile will it still grow?
Also it’s the start of winter here now, would I be better to wait for the start of summer to try to propagate or can you do it in winter as well
Cheers
Thank you for the insights on these seeds!!! am growing about 18 of them now. Using wet papertowel method in dark closet. One did split in 1/2, so I rolled each 1/2 in it’s own towel, now they both are sprouting roots!!!!! Have 2 Q’s for u or anyone pls………………HOW to support these 1/2’s in top of a jar? next, I have several seeds that are sprouting, yet the roots are growing out and ALONG both sides of the seeds, am afraid to try to straighten them out and then put in a water jar, so HOW to deal with this please? I now just have them in a little bit of water, enough to cover roots on each side. yikes. Any advice is helpful please. Thank you!!!!
I see the two types of water and wondering if rain water will work as well or be somewhat the same as well water. I collect and use rain water for many of my other plants instead of public water.
Rain water is an elixir for houseplants.
I root is growing but the seed broke into two. So l’m leaving the two half together with the paper towel to hold the two halfs together. Will it still kept on growing or do l have to start another one
I always have a few growing at once just in case I accidentally kill off one once it’s grown. So go ahead and start another…however keep growing the one that split. Once the root is strong enough, it should be fine. I had one that a side of the seed split and fell off, and it did just fine without it. But it was a little harder to keep it balanced and upright in the jar.
Thank you for the directions to grow an avocado tree! I have a 12 year old tree I started purely by accident. It’s been repotted several times and topped once. It loved my PA home and grew to the ceiling. I am a fan of the mini avocados so let’s see if I can revive my green thumb.
That is AMAZING! You are so lucky to have it produce too! A friend of mine has had hers for almost 20 years with no fruit in sight…but it still makes for a beautiful tree. I hope to be so lucky as to have as much success as you have. Thanks for sharing!
Not really sure why specific water? I use tap water and they do just fine. Anyone worried about chlorination can fill a an open container and let it sit a few days the chlorine will evaporate out. While is extremely difficult to get them to bear fruit it is not at all impossible in the right conditions. Avocado trees take up to 6 years to bear their first fruit. And it will probably never happen (or rarely) inside the house in a pot. But if you live in hot climate and plant it outside in the dirt where it can grow into the tree it’s meant to be it can and will bear fruit.
Again. If the conditions are right. My mother took many avocado seeds (collected from avocados eaten from the store just as we’re doing) to Thailand and had a small avocado farm for many years. It took 5-6 years of babying them IN THE GROUND after sprouting plants for them to bear fruit. She had up to 13-15 trees at one point. Thai people don’t typically eat avocado but she loves them so much and she gave them away freely. Yes, they produced that much fruit. From seeds from grocery store avocados. Yes.
Tragically they all caught a disease or got over watered when she was away for a year by caretakers who didn’t care for them well. Almost all of them died at the same time.
Having said all that. Your plants will only grow into fruit bearing trees if put in the ground and temperatures are never freezing. They like hot weather all year round. But if they’re in the ground obviously you can’t bring them in during the summer.
Enjoy the journey and the destination won’t matter! ❤️
