How do I seal it?No. Cut off the dead part somewhere in the live section, seal the cut and wait.
It’s a schefflera bonsai and it sits on a window ledge. I water it when the soil is dry and I am from Ontario, Canada. Here’s a photo of the whole plant.Knowing what species it is and where it's kept/how it's grown would help.
Many bonsai people use "cut paste"...search Amazon. But wood glue or even white glue can do in a pinch. The idea is to protect the cambium around the cut from drying out which, in tern, can help with die-back issues. It can also help prevent fungus and bacteria, etc...from entering the open wound.
Whether this is always needed or not is debatable. Some species respond better than others. Where you live matters.. I seal cuts...but not on everything. A stem that small I would rarely seal on anything here in my climate.
You call this a "branch". Is there a trunk? What does that look like? This branch doesn't look good and looks close to the ground so it may be the entire plant is at risk
More pictures showing the rest of the plant, a species identification, and some basic notes about the care/history until now would help.
But, I'm sorry to say that from this one picture, it's not looking good![]()
Thanks for the advice! How much should I be watering this plant and how should I go about acclimating it?I almost said umbrella tree...the leaves are pretty distinctive.
I'll be honest with you...it's in pretty bad shape for a schefflerafor comparison, here's one of mine.

I'd place money that the biggest difference between yours and mine is mine lives outdoors as long as night temps are above 45F. In the winter, it lives in a bright window that gets direct sun (casts a shadow) for several hours.
Ontario is tough on tropicals. They like bright light and humidity. Many will tolerate indoors but often slide downhill the whole time...which can be years! Mine shows signs of suffering over winter then it gets re-invigorated over the summer.
If you can get it more light...or even slowly acclimate it to outside for the summer, and it should fill in. If it starts getting too leggy for you, they root from cuttings pretty easily. Yours needs to bounce back a little first: light, warmth and time...
