| Post subject: | Acer Sango Kaku Air Layer |
Hi folks, I put an air layer on an Acer Sango Kaku a while ago - following all the advice you guys on here gave me. Growth was pretty slow above the cutting point but the last week - 10 days its started growing a gain with a couple of good shoots taking off. I am guessing this is a good sign - does it mean that its ready to be removed? I think I did quite a good job wrapping it up with sphagnum, black plastic and cling film - if I take it off for a "peak" and its not ready I'm worried that I might damage it trying to put it back on! What do you guys normally do? Thanks, Andy |

Presumably the sphagnum is wrapped in cling film and the black plastic is outside that. Could you remove the black plastic and take a peek without disturbing the sphagnum. If there are loads of roots that are all over the place "bag bound" so to speak then it's ready. They'll only be growing extensively in the summer but you could leave them as long as possible until the Autumn if you're not sure. I've only done a few of these myself but those would be my thoughts. |

Don't be fooled by the top growth. Have a look at the roots, they will be clearly visible through the cling film, and be patient. Make sure the bag is well filled with strong roots before you remove the layer. |

Hi Gary - well kind of!! I read it wrong so I did spaghnum moss, wrapped in black plastic and then that was wrapped tightly in cling film. Daft now you've pointed it out that I did it my way  I'd have to take it all off - and then put it back on if there's not enough to root. What do you think? Leave it a few more weeks?

I'd take the black plastic off carefully and then rewrap. It's worth having a peek to make sure it hasn't bridged the gap . Some plants callous then root quickly, others take months even years to get enough roots to survive. I've put on nearly 100 layers this year. Some were ready to remove in just over a month, others died, around forty have good callouses but no roots yet. |

Thanks Penny - I'll have a look tomorrow. Wow 100 layers!! You've been well busy - what have you been putting them on? |

I live in the algarve, so most of the plants are half hardy. Edible figs were the quickest, bottle brush trees, and campsis climbers produce the most roots, Judas trees produced lots of roots but the leaves looked sick until the layer was removed. Now they look healthy. Oleanders rooted well. Bougainvilleas also. Citrus were also good. Pistachio and stone pines just died. Kermes oak, olive and carob have all calloused but no sign of roots after four months. I also did a firethorn but the whole tree died! I also have a load of others which I'm not sure what they are. I can't get moss, so just use a thick layer of potting compost mixed with catlitter. I use a plastic bag but no black plastic. I have to water twice a week using a wash bottle. The temperature is no over 40c by day so keeping them moist is the main problem. |

Brahma, you won't get a lot of top growth above a layer because the ring bark stops the sugars from the root getting to the foliage. Look below the ring bark- a good indication that the layer is taking is back budding or increased growth BELOW the layer point. From experience I look to separate crin early to mid September if I start in mid April - the bag is usually full by then. Your success rate rises with patience - more root, more vigour. After separation bury the whole root ball a few inches below the surface & guy or tie it down so it can't move. |

I agree with Paul - although layers can take quickly patience is a virtue in this case - nothing to lose by taking your time. However a quick and careful peek will satisfy your thirst for knowing where you are. |

Ah - I assumed that new top growth meant that it had pushed some roots and the top was growing because of new roots! I think I might have a look to see if anything is going on or whether it has bridged the gap. So can you leave an air layer on for too long? If it's pushing roots and they fill up the "moss bag" will it have a detrimental effect on the layer? I'm quite happy to leave the layers on for longer if it gives me a better chance of success |
