poisonous resin from Robert Young?

15 years ago

over the winter i was growing Robert Young in a pot indoors; i made the mistake of putting the pot near a south-facing window and the plant didn't do so well. once the weather warmed up this spring i placed the pot outdoors and it seems to be doing okay now.

the weird thing is, when i finally moved the plant outdoors, i noticed that the area it occupied inside my apartment was covered in a fine, sticky resin that came from the plant. the window sill and window are covered in the stuff.

also while the Robert Young was indoors, next to it i had a pot of Walking Stick (Chimonobambusa tumidissinoda) which also did very poorly. Personally, i believe the direct sun and dry conditions are what damaged the Walking Stick (it has since slowly died off after transfering it to an outdoor grove), but could the resin from the Robert Young have had anything to do with it? and if so, should i be careful transferring the Robert Young to a grove that has some Madake and Vivax in it (both fo which are doing very well)? The Robert Young culms are under 1/2" diameter....

thanks in advance.

Your plants were infested with plant-sucking pests which left behind excretions called honeydew, these being unable to utilize all of the sugar in the plant sap and pooping it out.

Inspect them now for bugs and treat accordingly. Use a magnifying lens if you can't see anything otherwise.

whoa. bug dung? rather icky.

well, relieved it's not the plant itself. also makes me feel better about the conclusion i drew about the Chimonobambusa's death.

thanks for chiming in!

Aphids as well as mites are frequent on bamboo plants here. Thin-leaved plants from wet climates seem to be especially favored by mites, when grown under dry conditions.

The death of your plants was probably due to being indoors(not tropical species). I had the same thing happen when I planted mine outside after being inside for the winter, but it came back from the root/rhimozomes. If yours didn't dry out too much it could still be alive!?
