allright now you can graft onto them. A few years ago they had Wurz avocadotree's for sale in that street of World Nurseries.

In Borneo they grow avocadotree's who fruit twice a year, that might also work for you if you can get that variety.

Hi Suzi, I kept it indoor and watered every three days. I think I had waited too long when the seedling was ready to be planted with soil. The soil was normal potting mix for seedling and was well drained.

Hi Bangkook, I don't think I would know the variety and how to graft onto them?

Just google for: grafting avocado, there are loads of video but it's the same technique as any other fruittree.

Avocado's don't like to be repotted or planted. Best would be to plant the seed at the right (prepared) spot and graft a scion onto that. (or multiple scions for a cocktailtree).

I see you made pictures, you can also just grow the pit in a pot with soil and it should grow. You can just practise the grafting, you cut a scion of and try to graft it back onto the same tree as exercise.

But if you want the tree to fruit fast then you better get it grafted. And also put it in a bigger pot. You won't get rootrot fast in a pot but you need to make a good draining soilmix because it can rain daily in singapore. Mix the soil with cactussoil or charred ricehusks or perlite or sand,

I guessed that it needs to be grafted onto another avocado tree or just any other fruit bearing trees?

No other fruit trees will accept an avocado graft. It has to be another avocado. The problem with seedling trees is they take forever to fruit and then the fruit may be very unlike the fruit from which you obtained the seed. It could be great or terrible.

Look around and find someone with a bearing avocado and see it they will let you have a cutting to graft onto your seedling.

With the seeds you don't know how it will develop....you could have small fruits as big, you don't know if they will be self-pollinating or not....better to choose a grafted Avocado....
