Title: question about Kiyo Hime
Post by: augustine on January 31, 2014, 09:25 AM
Hello All,

I bought a small Kiyo Hime Japanese Maple last April which needs to be repotted and live in zone 7, Central Maryland. We also have had record cold temps. The tree in question has been stored in a plastic shelter buried in mulch. I open up the shelter whenever the afternoon temps go above 30 degrees.

I noticed this morning that the buds are very fat in spite of the cold. I have been informed that this variety and other dwarfs start to leaf out very early.

How early will the buds open? Can I expect them to start to open within the next week or two? I need the benefit of your experience. (I will repot when the buds just start to open and keep it from the cold and freezing once it starts to bud.)

Thank you.

Augustine

Do you have a thermometer in the enclosure?  Trees are tougher than we sometimes think; especially bonsai in training that we pamper.  Some dwarfs and witches' brooms of Acer palmatum do pop earlier and / or have a greater sensitivity to an increase in temperature as we close in on Spring.  It would be a good idea to keep temps in there as close to 40 degrees or so if all the plants in there are temperate species.

Easier said then done Owen what with these insane temps.

I understand the issues involved with the nasty winter this year.   It's hard to moderate temperatures in a residential situation (which I have to do as well).  A plastic tent is hard to moderate.    Worst case, put it in a sunny window if it pops early.  You will not be alone.

Thanks Owen.

do you have an attached unheated garage?  that would be ideal for overwintering it. 

make sure your makeshift shelter isn't counterproductive.  mulch produces heat.  enclosed plastic (even 4 sided with open top) exposed to sun light gets very warm.

overwintering is not about keeping deciduous trees warm; its about keeping them cold and avoiding big temperature swings.  your maple is much better off exposed to constant single digit and negative temps than constant freezing and thawing.  when dormant, it doesn't need sun; sun only creates risk.

it doesn't need heat or light; it only needs protection from drying wind.  it won't need water if its frozen; and very little water if not frozen.  buds swell even during winter.

Don.

Thanks for the info. I have a good idea of how to proceed now.

Best to all,

Augustine

I have another question about kiyo hime. Does it air layer well? I have a small kiyo hime that has a branch that needs to be removed. The branch to be removed is about half the thickness of a pencil but has some interesting shape and branchlets. I want to air layer it rather than just cut it off. When is the best time to start the layer?. The buds are swelling some here with upper temps in the 50-60 range here in Georgia. Any suggestions on techniques for air layering would be appreciated Thanks

I've been propagating and training Kiyo Hime Japanese maples since I introduced them to the US bonsai community in the early 1970s. They air layer and root easily.

I think your branch is a bit too thin to air layer. Why not try rooting it? You can try as the buds open or later on in spring when the leaves mature. They root easily.

Bill,

Thanks. The kiyo hime is one I bought from you. And I am looking forward to the pine and arakawa maple you will be shipping soon.

I appreciate the suggestion on cuttings.

I would layer and repot at the same time and move it into the garage or somewhere where it won't freeze. Maybe  buy some lights and place them over your tree until the deep freeze is over. I love my lights at this time of the year so I can get an early start. I start with my maples then on to my fruits, and by then I start work on my conifers. Works for me. Just try to keep thei temp at about 40 f or so.
