My tropical hibiscus has several branches growing from the main trunk. Are these considered suckers and should I trim them or are these a good thing? I just got the plant this year and besides a few yellow leaves it seems pretty healthy.
Without a photo we can only guess and generalize.
Branches growing from the main trunk are not necessarily suckers, and may be just natural branching that should be preserved and not removed.
If you mean that there are multiple shoots coming up from the same area at the low point just above the soil level, then those might be considered suckers, and maybe they should be thinned or removed.
