I just planted new hops in 20 in pots and I'm about to fertilize with 20-20-20 miracle grow. I hope this isn't too much for the new plants. Any ideas before I give them a shower in the stuff?

Yeah, it's actually the Schultz brand. 20-20-20 is what it's labeled as. Otherwise I also have the miracle grow, 24-8-16 NPK. Which would be better? They are granules and there is not adjustment for strength.

by the way, I already have it in potting soil, so I'm not sure how important fertilizer is right now either...

Yeah I took a look at that already...seems to be for hop farming. Thanks.

I use a 20-20-20 liquid - but mine are in the ground. I also use a 19-12-9 slow release peletized. - with yours in pots Id be careful with it.

Cheers

I'm pretty clueless when it comes to fertilizer. the numbers are a ratio of nitrogen, pot ash, and Potassium right, or am I wrong on that?

I use 16-16-16 on my lawn and it makes my grass grow like crazy and look great. Is this fine for hops too?

I know the guys at Puterbaugh farms "hopsdirect.com" say Miracle Grow is fine to use, but was hoping someone could offer a more in-depth breakdown.

thanks

The numbers are N-P-K (Nitrogen- Phosphate- Potassium). Each number represents a percentage. So if you where to use 10-10-10 rather than 20-20-20 it would be exactly the the same if you used twice as much.
Nitrogen (the first number) is needed for leafy growth. Phosphate is needed more for flowering, and Potassium is needed all the time for root growth and some other stuff i can't remember at the moment. So during vegetative growth (before flowering starts) you want to give it lots of N and a bit of K (potassium). When it starts to flower you want to give it lots of P and still a bit of K.
Don't take this to any extreme; a vegetative plant needs P, and a flowering plant needs N. i.e. a 15-8-10 for veg, and 8-15-10 for flower would be good (i'm just pulling these numbers out of my "donkey", they are likely not available at stores)
But remember, these are just ratios. 15-8-10 is basically the same thing as 30-16-20, it's just a matter of dilution.

If you're planing on dumping a bunch of time release on them you'd want something more like the 20-20-20 to cover all growth stages.

All that said; you'd be much better off in the long run if you used organic fertz, like composted manure. Chem fertz work great for a few years, but they f$%^ up your soil after years of use.

Would I be best off then to dilute the 20-20-20 to 10-10-10 in a watering can and fertilize my container hops say once a month?
