I have a Kelway ph meter. It is the best. It's more of a professional model. I've had mine for years and have done many ph tests with it. With this one just stick it into the ground, wait a minute and then look at your reading. Then clean it off and it's ready to use again.

OK - Santa Claus brought me that top unit Kelway HB2 (I was a very good boy all year :) ) Two questions: 1-what is ideal ph & moisture reading for minis? 2- what is best way to adjust if actual ph is high/low ?

Ph for roses is about 6.5-6.7. I don't use mine for moisture. But I don't grow mine in pots. I'm glad you got one. Mine has been used a lot over the years. I'm the President of the Stephen Decatur Rose Society in Decatur Il.
I tested everybody's soil in our Club!

Thanks Dan. My pots are presently in the garage waiting for spring but some growth is showing so things look good. I'll test ph when I move them outside later. Depending on reading I may be back to you for advice on correction techniques. BTW - flying to MDW tomorrow for meeting in Downers Grove. I really like Chicago and surrounding area - you live in a nice part of USA!

I just used my new ph meter for 1st time and got ph reading of 6.2 Should I raise the ph and what should I add to the container soil to help? Thanks!

A pH of 6.2 is just fine for roses. If it gets much lower, say 5.9 or so, then add a little lime to the soil to help raise the pH back up. Lime is slow acting, so don't expect to see the reading jump back up in a couple of weeks. However, it will do its work and eventually get the reading back up. Some say 6.0 - 6.5 is the best range, others say 6.2 - 6.7. Either way, your current 6.2 is fine.
