Hi Sean, I've used Dynamite slow release. I've used the red, green,purple or yellow(Citrus and Palm) although the Citrus one is not as easy to find. Lowe's has it with their private label and is made by the same company that makes Dynamite(Florikan). BTW,my Lowe's right now has it for half price(Citrus private label) , I think they are discontinuing it? I mixed it in my gritty mix when I potted it up and supplement with Foliage pro at 1/2 strength about once a week or so during the growing season. Right now I am not fertilizing because December and January is the time they are suppose to bloom and I don't want to encourage a growth flush instead of blooms...but my mango tree is 4 years old and is mature enough to hold fruit. I have another potted mango that is less than a year old, so I do fertilize that one when our weather is warm and its growing. If your tree is only a year and a half its probably too young and not mature enough to let it fruit so I would continue to fertilize it if its growing...but don't over fertilize it...1/2 or less the recommended would be best...so you don't burn the sensitive roots, that's why a lot of people recommend fish emulsion for Mango trees, they are pretty mild. Since you live in zone 10(Miami area?) your growing season is much longer that most of us. I would concentrate letting your Mango tree grow and mature a little more then maybe next year you can let it fruit. Good luck! Below is the Dynamite fertilizers I use...you can also use Osmocote (very similar) also a slow release and won't burn the roots. Here is a link that might be useful: Dynamite Fertilizer

I dry all of my fruit skins and then grind them in my coffee grinder. Mix them with worm castings to make a complete fertilizer. To get the proper measurement find out what the NPK needs are for the plants you want to grow. Then go to https://www.thenutrientcompany.com/organic-npk-values to find out what nutrients the various fruit skins offer. Dig this into the soil at least 2 weeks before planting. It needs to sit for a couple of weeks to compost before spreading around growing plants.

You're welcome Alicia and thanks for the nice comments. I used the Alaska brand and used to buy it at WM and Lowe's till they quit carrying it. Now I have to buy it at Ace or a local feed store...more expensive unfortunately! But you can buy any brand, I know there's another good one called "Neptune" I think? I'm hoping WM will start carrying it again this coming Spring? I've used kelp and have had very good results too and it certainly can't hurt...just don't overdo with the fertilizer especially the ones in pots. As long as you use 1/2 or less the recommended dosage while its growing should work out great...mangoes are a little more prone to root/leaf burn than some of the others, so its best to fertilize "weakly". Oh, I also found out that Nutricote and Florikote are the same as Dynamite and they supposedly sell it in larger bags. The company that makes them is "florikan" Below is the link with an #800 number. Good luck and Enjoy your new trees! If I lived a couple more hours south I think I would have at least 20 different kinds of Mangoes,lol...I just hate covering/heating so many trees during freeze!

Hi tropicbreezent, I live in Boynton Beach west of the Turnpike, I have never had my soil tested. Realistically that would be the logical thing to do to determine what type of nutrients and ratio to put back into the ground. My trees produce very well and the varieties I grow are delicious. I would fertilize monthly from March - October perhaps a quarter of the reccomended amount each month up until October at which time I would apply a larger amount with a heavier ratio of potash. TB, my thinking is that I probably only need to fertilize the trees 2 or 3 times a year and water as needed and cutting back on watering from October to February. This winter we had near record rainfall in Palmbeach County. I don't know how that extra rain will affect production this year. I often feel that I throw everything at my trees but they would do just as well with less. I'm trying to find the right balance of fertilizer and schedule to go by. In my surrounding area there are several of us that grow mango trees. Our fertilization plans are all almost the same except one neighbor who does much less but yet has high productivity and very tasty mangos. tropicbreezent thank you for responding and giving your advice, I certainly appreciate it.
