Roses fall in the category of the strong growing plants and great demands are made by them on food reserves of soil.
It is necessary to follow some manuring programme in a regular fashion.
It is also necessary for this programme to be in balanced form.
It is not considered good to use the natural manures just like dung from some stable in its fresh form.
It is advisable to store it and let it loser its freshness.
It is sufficient applying some large barrow load containing manure to about twelve sq.
yards as dressing.
The time which is best to apply it is right after pruning.
If you can't find dung then as a substitute you can use garden compost, made properly, leaf mould and peat as well.
But it is a fact that they don't have nutrient properties like those of natural manures.
Natural manures will only be found in enough quantity only in some cases having soils that are highly fertile.
These can be a source of maintaining sturdy growth.
Most of the times it will be required by soils to have a fertilizer dressing with some long lasting effect that can provide phosphates and nitrogen.
With the passage of time the feeding properties will be given up by the fertilizer and it might be used with 4-6 oz per sq.
yard.
It is good to leave the application of some fertilizers that can act quickly and are made from ammonia's sulphates, lime's superphosphates or any other such in organic chemicals.
In summer or spring seasons more top dressings can also be given.
Many home made formulas are also there with the rose enthusiasts but their preparation as well as fertilizer is far too time consuming whether it is specially blended fertilizer for roses or some general one.
Whatever the case is, the instructions of the manufacturer about the application rate must be followed at any cost.
