Although not intended to be reusable, I found the insert can be
removed from an empty bottle so that it can be reused with an
alternate fertiliser which works out much cheaper than buying new
MiracleGro bottles. After working out its dilution ratio I tried this
with Phostrogen powder (the general purpose / high 'K' one). The
problem is, just as with the original MiracleGro concentrate, there is
a certain amount of un-dissolved matter present which promptly blocks
the pinhole. Infuriating!
Can anyone recommend a better device which can be used with Phostrogen
powder or other solid feed-stuff?
Thanks

Make up the concentrate the day before use give time for all crystals to
dissolve, mix with warm water.

Someone gave me one of these liquid feeders with a supply of the
bottles of liquid last year. Still unused but I've looked at the
bottles carefully (both plant and lawn food varieties) and I cannot
see any undissolved stuff in any of them. I doubt that my friend would
have given me one if they had encountered any problems with theirs.
Maybe you've got a duff bottle?
There's a Miracle Grow (granule type) hose end feeder on eBay at

among lots of other places. Phostrogen used to market one but I
haven't seen it anywhere for years.

Make the hole bigger.

Thanks for the tip. I did try using hot water to increase the
solubility of the Phostrogen, but with limited effect. I suspect the
problem may be that certain of its constituents have a lower
solubility which is not a problem when applied by watering can.
Salts of Nitrates and Ammonium salts (ie. 'N') tend to be highly
soluble, as do Potassium salts (ie. 'K'). I am less sure about
phosphates (ie. 'P'), these might be much less soluble and salts of
some trace elements (eg. Ca & Mg) tend to be quite insoluble.

: Make the hole bigger.
If only life were that simple! The hole provides the dilution
mechanism. Unfortunately, enlarging it reduces the dilution factor,
making the device less effective.

Phostrogen powder use is specified at a concentration of 1 level
teaspoon / 2 gallons water.
Using a calibration procedure with some water (containing a dash of
food colouring) in the bottle I got a result of 9.5 level teaspoons of
Phostrogen powder per 475ml bottle, to get the same dilution as 1
level teaspoon in 2 gallons of water.
If you try it please let us know how you get on.

Yes. That might be right. I could try another bottle but they are
rather expensive for the amount of feed they contain...

Interesting. Do you know what it was called? A second hand one

I've got one of the "old-type" Miracle Grow feeders and it's fine
though I use it with Phostrogen (don't like the Miracle Grow product).
I just assumed the new type feeder was ok.

A quick web search reveals two old products, the Phostrogen "Handy
Feeder" and "Easy Feeder". They also did a "through feeder" that you
could screw to the wall - great as you could use it with a sprinkler.
You could try filtering the liquid through something like a coffee
filter paper to remove the non-soluble bits. The trick with another
feed is to work out the right strength of liquid to put in the feeder
good luck with that!
The only other hose end feeder I can find which might be suitable is
at http://www.gardenwizard.net/#/online-shop/4519662637. (I actually
use Plant Magic feed with a watering can but will get one of the hose
ends to try it - could save a lot of carrying!)

You could try looking at this link

It's now illegal to apply weedkillers through hose end diluters, I
don't know about feeds, they probably havn't got around to them yet.
In the US of A they are very popular amongst dahlia growers.

My thanks to all on this thread for the URLs etc. Since doing a
couple of applications with the MiracleGro unit my Dahlia's have had a
big growth spurt, are now in full flower and look magnificent!
Presumably its the added fillip that a foliar feed gives over watering
the soil with Phostrogen using a watering can which is what I've done
in the past.
