Great for organic foliar and soil drench feeding

Great for organic foliar and soil drench feeding
Every spring, we replenish our gardening container soil with fresh compost and amendments. It's so important to provide a good source of potassium for developing healthy roots. When I ordered this Cz Garden Supply Sulfate of Potash 0-0-50 Fertilizer, I did not realize it is a water-soluble powder. It will just wash away after rain and/or waterings. However, once the seedlings are about 3 " tall, I do begin a 7–10-day organic fertilizer foliar spray schedule that's dependent on rainy weather. I can include a 1/2 tsp. of this Sulfate of Potash into the 1 gallon of water. I also add a fungicide, Neem or B.T., baking soda, and Castile liquid soap to protect against powdery mildew and some invading insects. This 4 lb. bag will last quite a while, as long as I keep it sealed and under cover.

It's a decent fertilizer.
I received this about mid way through the growing season so I've only just sprinkled a small amount on the soil, then watered heavily.
The plants seem to be enjoying it.
A week after dispersal, they're all doing great!
I have a fair amount left so next year I'll mix it with the initial potting soil.
I recommend it.

Medicinal plants LOOOOVE this, 1/2 TBSP per gallon per watering once or twice will stop those burning leaf edges right in their tracks. 1 TBSP per 5 gal of soil works as a good initial amendment as well.

This kicked my struggling banana trees into overdrive. Our trees got shocked from a late freeze and when Temps started to rise the trees didn't do much. Within 24 hours they woke uo and started growing crazy. Also amazing for tomato plants and any other fruit bearing trees

Vine Customer Review of Free Product( What's this? )
I don't have the ability to analyze this fertilizer. I must accept that it is what it says it is. I've put it in my duster, and spread it around the garden, as well as the yard. I expect that the plants will take up what they need, as they need it. The fertilizer spread easily, without clumping up and clogging the duster. I'm happy with it.
