Fertiliser

Hi to all, just wondering does anyone use Sudden Impact for roses and what are there thoughts on the product??

Hi Martino. Yes I use it, I find it's excellent for roses grown in the ground. I also use manure (horse or cow) to enrich the soil. For pots, I use Strike Back.

Have a look about at some of the cheaper organic fertilisers. You may have to out twice as much on but you will find if you buy large bags you will save some dollars.

Just make sure that the potassium levels are up there, but even if you buy a bag of potash as well as a big bag of organic fertiliser you may still come out a lot better off dollars wise.

Martino, I forgot to add that as a member of rose Society Vic, I'm able to get a good discount on Sudden Impact. Don't know where you are, but maybe there's a similar discount available in your state's rose society?

Martino, your question about 'Sudden Impact' is very broad. Why do you ask, have you seen results from it, what have you used before, have you coincided other forms or brands with the same ingredients, is it that it suits your time frame. If you broaden you question I am sure there will be more options. "Marketing" in today's society gets us all IMO.

I have used manure too, sometimes with a bit of Blood and Bone and potash. Only once a year though, in autumn or winter.

I can't say how this stacks up against chemical fertilisers as I've only had roses for a year and I have never used the chemical ones.

There is no doubt in my mind that Sudden Impact is the best general fertiliser for roses however to use any fertiliser exclusively can be detrimental. I would suggest roses be given a varied diet including cow manure, worm casts/juice, liquid fertiliser, Seasol, Seamungus blood & bone, compost etc. if you are in the vicinity of a rose society join and you will have access to Sudden Impact and Seamungus at incredible prices.

thanks to all, a local store had a promotion on sudden impact and were flogging the 10kg drum for $18. though Ausrose you are correct a varied diet is the key on feeding roses.

Hi guys with using cow manure to feed roses how is it best applyed sprinkled around the plant etc a handfull or other methods.

Put a handful or two down, tickle it into the soil, and water.

I use a combination of fertilizers,,,,,manures only give you a certain amount of trace elements, so you need to add chemical ones to balance it out....I use cow manure as a mulch and as it starts to break right down, I turn it over into the soil.......one good thing about doing this way is that in the last year, I have had only about four weeds......oh lucky me.....

Manures are good, however, Australian soils are notoriously short on Potassium so you will need to add Potash to your soil as well as the manures.

Sudden Impact is 9:4:12 so it contributes more than enough potassium to roses. One of the criticisms of SI is that it builds up a detrimental amount of potassium if used exclusively over a long period.

That's correct. A figure of about 8% would probably be a better long term average. However, most growers want that sudden impact that the high level of potassium delivers without thinking about the long term affects.

Most manures contain very little potassium thus the need to add it to the mix.

Yep, very true. 

I think you can use wood ash from your fireplace in lieu of potash?
