2019年9月29日 · I plant the entire pot int the ground back filling with half bonsai substrate and some organic. It allows the roots to escape the cut away growing feeders at the top of the root ball. Come spring I’ll cut away everything below where roots escaped, setting you up for an easy repot. I did this exact thing with 3 pyracantha in July this summer.

2013年7月10日 · If the parent tree survived Chicago winters, it's a safe bet the layer will too. The genus Pyracantha includes a large number of cultivars/varieties; many that do well in cold climates. I collected mine on the MS coast, but has done fine with little protection when outside temps dipped into the lower teens for a few nights at a time.

2017年8月6日 · Fire blight is the most common and most difficult to contain. It requires total removal of infected branches to control and for a yard plant this is acceptable while for a bonsai it is devastating. Most of the infecting fungus on pyracantha comes via insects and birds which forage over the prolific flower bracts in early summer.

2016年6月5日 · A few years ago, I pruned a Pyracantha. I put the cuttings in a jar filled with water, and forgot them in a shaded part of my garden. Three weeks later, I found them again, and to my surprise, they had produced long white roots! Here are some of them then and now: One I …

2016年8月28日 · Hello, Not expecting a great deal of comments, as there isn't much to say about it yet really! This is an air layer I started nearly 10 weeks ago, and what its roots currently look like. I did worry that they aren't quite the colour of roots I was expecting but, I …

2022年5月27日 · Here’s my little pyracantha I’ve been training for a few years now. This year the leaves have really gained some size & I feel it ruins the appearance a little. Can pyracantha be defoliate to stimulate a second flush in the same way I’d …

2015年4月8日 · My pyracantha is probably the slowest-thickening tree on my benches. I just removed copper wire from branches that was applied in early 2012, and after 3 full growing seasons, it was still not cutting in, even though it grew very strong each of those years. I don't have another tree on my benches that can remain wired for three years.

2020年4月16日 · Pyracantha are in the rose family, related to apples (Malus) and other members of the rose family. The "all in one" rose sprays that are used for hybrid tea roses will work without harming your Pyracantha. They are intended to be used outdoors, the "all in one" rose sprays are not labelled for indoor use.

2012年10月29日 · Hello, I am new to Bonsai and this forum as well. I have a pyracantha which has been declining. I'm mostly noticing defoliation now, although previously the leaves were turning yellow first. I read that pyracantha is susceptible to overwatering which can result in yellow leaves with green...
