Propagating Japanese Cherry trees

Posted: 22/11/2013 at 20:57

I have a few weeping cherry trees (Prunus kiku-Shidra-Zakura) that to maintain their form I need to prune. Ideally I would like to propagate them using these cuttings.

From what I have read they can only be rooted via air layering or softwood cuttings. It is too late for the latter (though I could wait till spring). Has anyone airlayered successfully or rooted cherry from hardwood cuttings?

Defo a Photinia - those flowers should come in white. The yellowing leaves are a sign of nutrient stress, normally lack of nitrogen. A weak nitrogen feed would help it ticking along till spring.

Greenhouse Condensation

If it's caterpillars they will be on the plants all the time.  What does the damage look like?

And they will leave little poo pellets that are a give away...maybe it is Vine Weevil.

I have found that opening the vents and doors during the day helps condensation. Insulation (bubble wrap) does help - at least it stops it dropping on the plants. Since I put tin foil on the floor of the GH that has also helped reduce condensation in my GH.

Can I repot in Winter

I am worried about the soil being waterlogged. I would take it out the pot and improve the drainage and squeeze the roots to get rid of excess water. With the improved drainage (stones, vermiculite, gravel or whaterver) and put the Acer back in the same pot. It will not be growing until spring and a quick way to kill them is waterlogging.

green house design, advice and experiences please

I have a wooden greenhouse with polycarbonate glazing. It is warmer than a metal frame and glass glazed greenhouse. You can hang things like insulation directly onto wooden frames. Polycarbonate as double glazed offers better insulation in winter and as the glazing is slightly opaque, you get the light but not full on glaze that glass offers.

Size depends on what you want to grow. I plant to dig down in my GH to get extra height and that also offers extra insulation.

I have not had any problems with GardeningExpress. I do not like paying £8 P&P but that is my choice of using them or not.

T&M plants tend to be small, too small for my liking and they often do not tell you the size of pot/plant that you should expect. Any problems have always been quickly resolved. There is no such thing as 'free'. You are paying £5-6 for the bulbs and a little for postage. In a GC you would get them cheaper! If you fall for their advertising then caveat emptor.

J Parkers - no issues and for bulbs they are very good. Plants are much larger than T&M and all have thrived.

I tend to use specialist seed and plant suppliers, all of whom I would recommend and would be happy to name but am not sure if this is the right place.

Cordyline indivisa

Keep it in the pot until spring, as you want to avoid overpotting with its problems of root rot. It would actually prefer to go in the ground - it should turn into a lovely tree within 5 years.

They like well draining, damp soil and frost free though are hardy. They do well in wet western Scotland and Ireland and progressively worse the further east you go. They were on sale as they are not as hardy as the normal Cordyline austalis.

Now is fine if you can keep them out of the frosts. They take till Spring to root.
