Just wondering what Osmocote most of you guys use?
Is there any drama using one with wetting agent

Wal

I can't see any problem with using that one Wal. The wetting agent should help the water to penetrate if the mix gets a bit dry.
What is the release period on that one? They make a whole lot of different types. Some release all the fert in 3 months, others last 9months. The one I get has a 16 month release period but you won't find that at retail outlets. I have to order in a 15kg bag from the supplier.

The one you have will have relatively low N rating but higher K because it is for flowering plants. All plants will be ok with that one but growth may be just a little slower unless you supplement with something with higher N like Thrive for the trees you want to grow faster.

Thanks again mate

It says to reapply every 6 months

That means it is a 6 month release formula.
No point in putting fert on deciduous trees in winter (no leaves to use it) but evergreens can and do use nutrients even in cold weather so when and which to apply will depend on the trees and your climate.

Hmmm don't think it's organic though
Can i still you it along side a liquid fert like nitrosol too

Wal

In short... Yes

Do you mean Thrive is not organic? You'd be correct there. You can use any fertiliser in conjunction with osmocote but what's the point of only using an organic when the osmocote is not organic?
Does your last post imply that you think nitrosol is organic?

Yep i thought / think the nitrosol is organic ... hmm i gather its not then, i feel more than a tad deceived given not only did the guy at the nursery say it was, but the bottle of my Amgrow nitrosol says organic hmm

To my knowledge the Nitrosol is organic. Made up with blood n bone, fish etc...
Osmocote is not. But its a good fert as long as you follow the instructions.

So i should stick to once every 6 months for the Osmocote, but i can powerfeed the nitrosol every week or so? Still worried I'm going to nuke roots lol but i trust all you extremely knowledgeable people:)

Have a look at the fine print Wal and Kirky.

This includes ammonium sulphate, urea, potassium hydroxide, potassium sulphate, Superphosphate and other salts plus organic sources such as blood & bone.

The blood and bone may be organic but the rest of those ingredients are all straight from the factory.
Also:

Trace quantities of impurities are also likely.

There are actually very few truly organic fertilisers available commercially. one of the problems is that a fert must have a guaranteed nutrient analysis and because organic ingredients vary from batch to batch and from season to season the manufacturer cannot guarantee the analysis unless they fortify it with chemical nutrients.
This is 'greenwashing'. Using terms to suggest organic without actually specifying that it is organic. Also beware of 'Organic based' which means the same thing - some organic but mostly chemical nutrients.

Powerfeed and nitrosol are 2 different products but you can mix osmocote with the potting mix and also water with any soluble fertiliser every couple of weeks. that's what I do here and get good results. Just follow the directions for each product.

My bad i didn't mean the product "powerfeed" i ment powerfeed as in pump the plant with nitrosol more than the "once a month" the bottle says

Thanks everyone again

One thing to remember about Osmocote. The release time for at a set controlled temperature (I think, but don't quote me, it is around 26*) That is to say, if you have 6 month Osmocote it will take 6 months for all the fertiliser to release from the pellet at 26*. Now during summer, when your average temps are higher the release is much quicker and can be as quick as 6 weeks if temps are constantly high. Say in the 37 -40 range. I usually replenish my Osmocote (same one you put pic up of) at least every 3 months all year round up here on the Fraser Coast.

Cool makes sense... where i am far north side of brisbane we hardly have a winter, i gather i would be close to the same as you
