Hi.

I have a small Acacia Confusa plant dying in my window It`s my first time growing this plant, and I could really use some tips regarding preferable growing-conditions.
Someone with experience?

Peace&Love

Try and make the conditions for your confusa similar to Taiwan & Hawaii for a start

Did you start the plant from seed or was it ordered already started? If you live in a cool environment than you have no choice but indoors but if you can move it to the outdoors in full sun if temps are above 70 or so it might do better. Look into its soil type and try and match it the best you can. The problem probably is that even if the plant gets direct light in the window for just a few hours(2-4) that really is not enough. Most plants prefer a minimum of six if they are a full sun plant. I don't know if this plant likes full sun or not but if it does that's likely your problem. Do keep in mind that if you move it to full sun its best to acclimate over time just in case so you don't burn your baby.
