Using Milorganite on Bananas-For the Ultimate Growth!
Many on the forum have asked how much Milorganite to use when planting their bananas, so here are a few of my consolidated answers:
If I am planting for the first time and the plant is smallish, I mix into the soil for the planting hole about 1 cup and then after the plant is in the ground I put about a half cup around it and then mulch on top with a good watering in. If it is an established plant like a Musa Basjoo, I take about 6 cups and spread it around the base and then mulch. As the season progresses I will put it on heavy around the base, a shovel full on the larger plants and a quarter to a half shovel on the smaller and medium ones. I will do this 2-3 times per season with super results. Keeping the watering up really helps too.
I've tried them all and the best by far has been Milorganite which is a mild 6-2-0 and I add some phosphorus with a 10-10-10 in the beginning of the season and then it is nothing but Milorganite and water. The results speak for themselves 15-20 foot Musa Basjoos, 18 foot Red Abyssians and 12 foot Red Blood Bananas. I have also had great luck using it with my cannas like Giant Peach that grows 14 feet high and looks like a Bird of Paradise and Canna Intrigue that has brilliant bold red foiliage that grows 10 feet in height. Try some, believe me you won't be sorry and will feel like you planted a "Jack and the Beanstalk" bananas.
If putting a banana in a pot, use enough to make up about 1/4 of the total fill of the pot. I know it sounds like a lot, but to a heavy feeder like a banana plant, it isn't and remember, Milorganite does not burn like chemical fertilizers. Mix it in well and even place some around the base of the banana plant and keep the water, sunshine and heat on the upside outside.
