Posted by brownmola San Diego (My Page) on

So I have a few newly planted 5-1-1 container citrus. I am using Dynamite Citrus CRF and am using a Foliage Pro with very watering. Does anyone use Ammonium Sulfate with their container citrus?

I used Ammonium Sulfate for the first time ever for my in ground citrus about a month ago and am seeing a lot of new growth on citrus that had been losing a lot of leaves.

Thanks!

brownmola, ammonium sulfate contains 21% nitrogen - all totally water soluble.
I cannot envisage it as the only fertilizer for citrus - except as a 'starter' for young plants - and then only in very dilute concentrations.
Here is a description of the product.

You can absolutely use ammonium sulphate on your container citrus. It is an easy way to give a nitrogen dose to a plant. Just dissolve it in water and fertigate. Calculate out your desired ppm and add enough to warm water to hit that target.

You can use it if you think your plant needs more "N".
I use it sometimes on my onions, garlics and other leafy veggies.
I think it also tends to acidify the soil a bit (not too much) due to presence of Sulfur in it.

Thanks guys! The citrus I have in pots was pretty neglected when they were in the ground and I want to try and push some growth/greening on them and thought dissolved Ammonium Sulfate would help. 1 tsp or Tbs per gallon sound okay?

Hullo brown,

Sorry no one responded so far but if it's not too late: usually for Ammonium Sulphate 1/4 per 2.5 gal once per week is fine, it's very easy to overfertilize with it since it contains so much N by weight, so best to start out with such a dosage. Bear in mind that's for container plants, so in ground something slightly higher (maybe 1/2 tsp) with lots of watering should be okay. I'll link a forum with some pictures of blueberry growth using that dosage ;)

Regards,
Dan

Thanks, I have actually transplanted the citrus into the ground and have been using Ammonium Sulfate in the soil in granule form. So far it has worked really well. Might try citrus in a container again later this year.
