I think you may have injured the seeds. There is a deep cut on the seed going diagonally. Try not to cut too deep into it.

It can take quite awhile before it sprouts. They do usually crack open. Change the water every week or so. Put by window.

I eat a lots of Avocados and leave the pits in the garden for compost, some are growing well even I do not intend to grow them.

I've had the same problem. Mom used to grow these things, and I watched her, but evidently I got something wrong. I'll try again this weekend!

Do an extra one with different water.

I don't think your doing ANYTHING wrong. Besides not waiting long enough, mine took up to 6 weeks to sprout. Then I threw them away :(

I tried this method before and even after several months, it still didn't sprout. I highly recommend that you just plant the pit into a pot. I got way faster results in the pot (2 weeks if I'm not mistaken) than the toothpick method

I've commented before about my 'method' for growing avocados: just toss them into a bowl of water and wait. That's it. Sometimes I toss one into a planter, burying it about an inch deep, and wait. That's it. I NEVER, ever use the toothpick method--when I used to do that, they NEVER grew. Seriously, just try the water method, no toothpicks, no cuts in the seed, just stick it in a bowl of water, refresh the water every few days, keep near a window if handy, and wait.

Do note that it can take weeks--or even MONTHS--for a seed to sprout. I've seen no particular rhyme or reason to it, just sometimes it takes days and other times much longer.

I just put the seed in some compost and it will sprout. My temperatures are always around 30 celcius, day and night. I think that's the trick.

Hi , I started 5 in Jan 2015 same method as You did, 2 just rotted , 2 cracked but no roots yet and the 5th I've included a picture :) Her Name is Eva and she s very beautiful ,, so just keep going it took Eva 4 months to grow roots , I planted her in potting mix and sand she was just a little twig for a month , my wife said "throw that dead twig out , I said "no way '" I watered her every week and now a couple months later she's a foot tall has 5 beautiful leaves , Ill keep her as house plant .Make sure once yours sprouts you plant it in good soil and sand make sure there are holes for drainage on the bottom . Good Luck,,

stick with it YOU WILL Be REWARED !

So, I had to post cause I had the same issue. I had my seed in water for almost a month and nothing. It was getting green (mold?) actually. So I thought it was just bug food, but decided to just plant it in the backyard. Not too deep but enough to cover it up. 2 weeks went by and I didn't notice there is a plant growing there, until the fiancé asked what I planted. To my much surprise, my little avo seed is about 8-12 inch tall and has 3 large leaves. Its been raining a lot down in s. Fl. But nothing too crazy where it's drowning the plants. The recommendation of everyone to just plant it in soil, is best and leave it alone for a bit. (Don't forget to water it, just don't drown it). I thought I killed my seedling, but she just wanted to be planted in soil to make her appearance. :-) good luck!

Don't use water, it can cause rotten...put the seed in a pot and let the smallest part on the top....it will sprout in few weeks

It can sprout using toothpicks and water. Make sure the pit is placed in the water correctly. Google for it.

I've always planted the seeds directly in the soil and they are always germinated.....

Just to join in, I have had two seeds grow roots via both methods, although neither have sprouted from the top of the pip. They say the soil method is a quick method, although mine hasn't sprouted. It has been in the soil for 3-4 months now! Guess I will just have to keep waiting!!

I did this to about 9 avocado seeds,and got 4 to grow,multiple is better,more chances to germinate :)

toothpicks is the best way,i tried every way and this was the best method,now im looking for avocado scionwood to graft to my plants?michaelky56@comcast.net also mango scionwood :)

takes about a month and a half to 2 months for the toothpick method,dont be discouraged,just forget its there and you will see results :) unless you need to add water

The pit starts to change color and rot... http://sgmygardenisgood.blogspot.sg/2015/09/growing-avocado-in-water-mid-september.html

In the soil, in spring, 1 month and it will sprout

move to the tropics. I used to toss the pits out into my uncleared yard house, and now I have about 30 avo trees coming up, some in not very convenient spots as we develop our property.

Steiconi, how do you like living in the Big Island? I'm considering moving there sometime next year.

I always thought they were the easiest. I have 3 avocados at the moment. I grew them all from the cup method. In water their slow but once in soil they take off. The tallest one I pruned but continued to grow straight wards. The short one has been dropped and the root completely broke but its still alive & healthy. The plant in the black pot is a mango.

And btw these are store bought hass

Hi,

not sure if you've had success in the past 2 years. I just wanted to say that I tried this method >20 times with the avocados I got from Woolworths (large grocery chain) and none of them sprouted. Then I got 2 avocados from the local vegetable shop and they both worked. So it might not be your technique that is the problem; rather the seed source. I wonder if some places treat the avocados before they're sold that damages the seed?

Anyway, good luck. One of my 2 plants is quite large now, almost a foot. It took a few months before I noticed any growth.

Also, I noticed the plant which I planted directly into the soil grew MUCH faster than the water method.

Maybe it's not warm enough. They like heat. I put my seed in the sun in a tiny little glass vase with water just half way up the seed. Didn't use toothpicks. It started sprouting a root so I immediately transfered it to a pot with the seed just as it was in water, just half covered by soil. It quickly sprouted a stem and leaves. After a month I planted it in the ground and it continued to grow. It's resting now that it's cooler here but should start active growth again once it gets hot out again.

Hi. I think the seed is sitting too deep in the water. I would let the bottom sit in the water no more than 1/3 of the seed. Also, I do not peel the skin off. Put the cup in the sunny(not too hot)& bright spot, and wait. Sometimes, though, it just don't want to grow, so I just start over with a new seed. Good luck!

Ah man but what do I do with the my useless expensive stupid bloody propagator now?! 🤣 I’ll just have to splash out on a new pot instead!

Roots require rooting hormone to grow. They make that hormone in the dark, which is why seeds have to be covered to sprout quickly. You can buy rooting hormone, but it's a powder. I have grown a tree from seed using toothpicks (no peeling or cutting first), but the same technique hasn't worked this time at least yet. It has only been 2 weeks, though, so I will leave it there and try something else for seed #2. It also needs warmth. Compost creates heat as it decomposes, so it would be warmer there year-round. I'm going to try soaking my seed for a few days, then potting it with the tip almost exposed, in a very warm place, and a little rooting hormone powder at the bottom.

I just did 3 seeds from my Wurtz and all 3 sprouted within 4 weeks using the toothpick method. I also peeled away the outer layer of the seed prior to placing them in water. This happened with indirect light inside my house changing the water once a a week and having the seed half in water/half out of water.

I have been looking at propagation from stem cuttings, and it seems that it is superior to the seed method because you get a genetic clone and it grows into a fruiting tree in four years instead of 10. There appears to be a group of people who use pieces of aloe vera plant to stick the stems into before burying in soil. Apparently, it is a natural root hormone. I definitely am going to try it because I have aloe vera growing in my yard, and I don't want to search for root hormone and shell out money when I have a potentially equivalent product at home. I also already have two grafted avocado trees. They are small, and I had already cut back the Fuerte, but I still haven't pruned the Mexicola Grande. I might use that pruned leader as a test. The Mexicola Grande would probably make the best root stock for grafting, anyway.

From my experience I would leave the toothpicks out of this. With the Avocado stone/seed while it's fresh peel off the brown outer skin carefully. Wrap it in some damp kitchen roll. Place it in an air tight sandwich bag for example, and place in a draw. Check on it in 3 -5 weeks you will see it split and roots shooting out. You can leave it for even a few months until you have a nice amount of roots exposed. At this point you can plant in to soil, or using the water method.
