You probably know that the key chemical elements contained in fertilisers are Nitrogen, Phosphorus and Potassium (Potash).

Taking away the Nitrogen leaves us with Phosphorus and Potassium. Now the easiest method of applying these two elements is by using Potassium Phosphate, which contains about 52% of a soluble Phosphorus salt and 34% of a soluble Potassium salt. It does not contain any Nitrogen, so Potassium phosphate would meet your needs exactly. Use at a rate of about 5 - 10 grams dissolved in a gallon of water.

If you can't find Potassium Phosphate locally, you should be able to get it via the internet. Type it into Google but make sure you add the word fertiliser or you might end up at the site of a laboratory chemical supplier!

If your after plenty of flowers only, use Potassium Sulphate instead, but Potassium Phosphate will give you plenty of flowers along with a well-rooted plant. I can't remember the rate for Potassium Sulphate offhand.

Bonemeal is a slow-release fertiliser that contains about 5% nitrogen,about 15% phosphorus but no potash. This will give you a strong well rooted plant, but will not do anything for the flowers.
