You can find fertilizers with a 3-1-2 or 2-1-2 ratio (such as 12-4-8). Avoid high phosphate or level phosphate (such as 10-10-10). P accumulates permanently in the soil and can cause deficiencies of other nutrients while suppressing beneficial mycorrhyzae.

Wise of you to get a test.

Thanks, should I take any action to get the pH to 6.5 or so?

If you have typical roses from the garden center, these are usually grafted on Dr. Huey rootstock that is fine at pH 7. If you have roses on their own roots, some varieties will develop iron deficiency at around pH 6.8.. The new leaves will be pale with greener veins. Other varieties will be able to take up enough iron.

To lower pH of heavy soil, add 1/2 cup of plain sulfur per square yard and wait six months for it to work. Use less in light, sandy soil. At pH 7, treatment is optional.
