Early September is the ideal time to feed your garden. Whilst you can add organic matter like sheep pellets or compost at any time of year, it is good to give some inorganic fertiliser over the next few weeks as your plants all move into leaf.
* Rose fertiliser for your roses and flowering plants.
* Citrus fertiliser for all your citrus and fruit trees.
* General fertiliser for everything else.
It is a good idea to feed when it is going to rain as this will wash the fertiliser in and make it available to the plants.
And finally, don't forget to make the amount of fertiliser relevant to the size and age of what you are feeding.
