My elm has brown leaves which I assume are fungal or pest related? Have sprayed. Should I remove all effected areas which will leave my elm almost leafless. I'm in the Pacific northwest in Canada, above Seattle. FWIW no other bonsai have issues and are thriving. The elm is in full/near...

Hey - similar challenges here. But am now following Graham Potter's seasonal pruning advice to see if it helps. Have you seen his instructions? https://www.kaizenbonsai.com/bonsai-tree-care-information/getting-bonsai-hawthorns-to-flower

Thanks - it's a sargent crabapple. From a nursery plant. Did a trunk chop about 4 yrs ago, and has grown well, but no blooms yet.

Hi - I've had a crabapple for a number of yrs (about 4 I think). It's happy and healthy, but has not flowered. Are there any particular pruning, or feeding tricks that I'm not doing right? I basically just feed once leaves are out, and repot every 2 to 3 yrs as needed, and try not to feed from...

How much charcoal and conditioner do you use? I've been using turface + pumice or lava rock (whichever of the two I can find). I will try to amend with some charcoal & conditioner.

Gorgeous - especially the hawthorn. What's your pruning / maintenance schedule for the hawthorn if you don't mind me asking? I've not had much luck with my hawthorn flowering. Do you do a hard prune in late winter, and then leave it alone the rest of the year?

Hi, Thanks for the reply. Tips of shoots only..... is that more suggestive of a fungus, that an anti fungicide eradicate? Looks like buds started to swell, then called it a day, went black. There are other areas where new shoots are starting to push out and other plants are now leafing out, so...

Hi, I went on holiday for 3 weeks, and just got back. Many of my bonsai are sick, with either a fungus or parasite / pest. What is this, and how do I fix it? It's effected a maple, juniper, boxwood, and pyracantha. For context: I live in the pacific northwest (mild / temperate / wet climate)...

Hi, I'm in the pacific northwest of N. America (north of Seattle). With JP Black & Red Pine, how late would you recommend fertilizing? Assuming early Oct would represent the last fertilization, for spring growth. Would you agree, or should I fertilize later into the autumn? Thanks.

Hi, I've been working on a Hawthorn for about 2 or 3 yrs (dug up from a friend's property). It's still very much a work in progress, however I'm curious as to why it hasn't flowered since I've had it. Aside from a bit of removing of branches that aren't working, I've left it alone...

Hi, I've got an elm, with leaves that are browning. Not sure why - ideas? Too much sun, pest problem etc? I'm in the pacific northwest, if useful. Normal daytime temperatures are around 20C / 70F. My soil is very porous (mostly turface) which generally works well for me with other plants...

Hi, I'm in the Pacific Northwest. I've got a couple of small trident seedlings (started from seed 3 yrs ago). They haven't budded yet, which is odd. If I scrape off some bark, it's still green underneath, so I know it's alive. Any reason why it'd be so late budding? Thx.

Hi, I'm on the west coast of N. America. Found this small tree growing - not sure if it's a type of hemlock.... Thanks.

Hi, I've got about a dozen or so small 3 or 4 yr old pines growing in the ground, over tiles, to get the nabari off to a good start (a few JP Red, JP black pines, a white pine, and a mugho). All started from seed, which grew in a pot for 2 yrs, and are now in the ground. Question: how often...

Thanks - here's a pic of the critter....

Hi, I'm in the pacific northwest, and in spring we get quite a few caterpillar / worms eating our plants. Suggestions on pest control that won't effect the bonsai negatively, but will keep the green things at bay? The critters are about 1/4 to 1/2 inch (up to 1 cm long) and are green...

Great tips, thanks so much. Interesting eastern vs. western hemlock. I'm from the w. coast of Canada, and knowing that it wasn't a mtn hemlock, I assumed that it was western. I'll try your pruning advice. thanks.

Hi, I got this hemlock about 1 1/2 yrs ago from a friend's garden when he was doing some reno's. Has been sitting in a pot since. No idea what to do with it. Ideas / suggestions? It's about 3 ft / 90 cm tall. Thanks. Cam

Can you give a bit more info on your fertilizing regiment? Thanks. Cam.

Eggs Hi Guys, Thanks for all of the advice. Hopefully I managed to remove all eggs, and we'll have to resign ourselves to never knowing for sure what they were - thankfully. I kind of wonder if it was moth eggs? Lots of moths (and wasps) right now in my part of the world. At any...

Hi, I found eggs on a few pairs of JBP needles today. I removed, but am not sure what they were. Attached is a pic I found online (this source too didn't know what they were). I'd like to know what it is, and how to prevent in the future PS If it's useful, I'm in the pacific northwest...

Interesting. Can you identify (perhaps colour) the branch that was bent? Thanks.

Lovely - I'm jealous =)

Love it.

Thanks very much. It appears that he doesn't (by default) ship to Canada, but I've emailed him to see if he is willing to give it a whirl.
