To give existing containers and hanging baskets a mid-season boost, we offer Continuem Nutritional Plant Gel. Continuem is the same product as FertiSorb, only it is already hydrated, and is applied using a standard caulking gun.
Continuem is meant for plants which have already been planted, either in containers or in planting beds, indoors or out.

Several shots in the root zone will provide up to 3 months of plant nutrition along with the benefits of a water-holding gel.
