Soil pH testing
I have a rugosa rose that is showing probable iron deficiency. I have an iron supplement, however I read that if the soil is too alkaline, that the plant cannot absorb nutrient supplements efficiently.
I have tried researching pH meters, but they have pretty dismal reviews.
Is there a place in Douglas County (or closer than Ft. Collins) where I could get a sample of my soil tested for pH?

Hi, you can come to Douglas County Extension Office at 410 Fairgrounds Road, Castle Rock, CO 80104 to pick up a soil test kit that you would prepare and send to Colorado State University in Fort Collins. There is a fee. The Routine Garden and Landscape soil test is $35. It tests for pH, EC, organic matter, nitrate, phosporus, potassium, zinc, iron, copper manganese, boron and lime & texture estimates. Results will be mailed to you.
