Treegator is not designed to be a permanent installation - it's portability is one of the features that make it unique - and we typically recommend that the bags be stored when not in use.

Yes. Additives such as liquid or water soluble fertilizers / stimulants / nutrients can be added to a Treegator Original.
To avoid any clogging issues, it is strongly recommended that the additives be pre-mixed in a separate container, and then added to the bag after filling to 1/4 capacity with clean water. NOTE: This is not necessary with dissolvable fertilizer pouches.
