Growing avocado in water - Mid September 2015

I have started growing avocado pit in water a few months back. They had sprouted and grown quite well for a few months and lately something happened.

The pit started to turn colour and I guessed they are rotting and drying up. It has not affected the growth of the seedlings and I'm not sure whether the pits are needed for further growth. The seedlings that are grown in soil after the initial germination in water had the pits still intact. Only one seedling in the soil has half of the pit turning colour. I tried to search in the internet for information on the pit turning colour and rotting but did not get any meaningful answers.

I will try to document in the blog on the colour change and possible rotting of the pits.

The pits were still in their usual colour even when the seedlings had grown to about one feet. I'm not sure whether it is due to the air-conditioning that the plants have been subjected to since the haze has come to Singapore. The seedlings were kept inside the room with the air-conditioning turned on for a few weeks already. I hope this is not the reason.

I tried to move one of the small seedling to the living room where it was not subjected to air-conditioning at night. Only one half of the pit has turned colour and dried up. The other half is still in it's usual colour.

There are new roots appearing even when one half of the pit has dried up. I think it is going to survive. I'm thinking of transferring the seedling to a pot with soil soon. But I'm still thinking whether I can still keep it in water.

The below pit has the tallest seedling but the pit has turned colour and possible rotting. There is no abnormality in the root system and I hope that even without the pit, the seedling can continue to grow. I'm also not thinking of transferring it to a pot with soil soon. I will monitor this for a couple of months. So, now it is mid September 2015. I will update the status in mid October. Stay tuned!

The root system still looks ok. There are more branching on the roots and I have changed the water regularly every week. Currently, I have moved the seedling to a room without air-conditioning at night to see whether there is any effect on the seedling.

I will need to prune the seedling too. I hope the pruning will not affect its health. The rotting of the pit may have been stressful to the seedling and the pruning may add further stress.
