This Down-To-Earth acid mix is designed specifically for hummingbird vines. That tells you that it doesn’t get much more personalized for your vines than this. Using this fertilizer as directed on your vines is the best way to ensure good growth.
This fertilizer contains cottonseed meal, rock phosphate, and kelp meal. That sounds strange, but these ingredients come together to provide nutrients to specifically vines.
The application method for this fertilizer is just like that of others. If your hummingbird vines are not mature yet, mix in the fertilizer before planting. This is going to help your hummingbird vines have a strong start. But, if your plants are mature and need some extra help, put it at the base, for a slower release of the fertilizer, which is what mature vines need.
