You have the best color on Boscobel !! I love its color and the beauty of your bush (better looking than the one in Austin Catalog). Is it grafted on Dr.Huey or own-root?

How's the scent? How do you fertilize it to get such deep pink color? Thank you.

That's magical, extensive, and large. Boscobel is a town in SW Wisconsin. But, I see it is a hunting lodge or estate in jolly old England, after which your rose is named. You produced a very nice video.

Hoang Ton What type of potting soil do you use? I grow tiny own-root roses for zone 5a winter-survival and I'm looking for the best potting soil, or additives to the soil for FASTEST growth. Also the best fertilizer to grow a tiny rooting (shorter than my finger) into at least 2 feet tall bush, so I can plant it 5 inch. below ground. Thanks for any info. on the best potting soil or soil additives for fast growth.

strawchicago, i don't use potting mix anymore, i use garden soil + native soil + manure compost for my pots, as for the other questions, i'm not sure, mycohriza fungi is best for root developtment

Hoang Ton: You help me a lot, much appreciated. One year I bought cheap potting soil (Schultz with mostly wood chips), and my gallon size own-roots actually shrank in such zero nutrients medium (except for blue pellets of chemical fertilizer). So 5 of my own-roots died through zone 5 winter when I transferred from pots into my clay. But previous years of planting smack into my clay: I have a higher rate of winter survival due to my fertile clay (with plenty of humus or decayed leaves), plus minerals for solid canes & roots.

I agree with what the poster Kimmsr stated below: "Soil Nitrogen availability is highly dependent on your soil temperature which influences bacterial activity, so if you test your soil for N when it is fairly cold and the bacteria are not very active the test will show little N available. I have found that if the soil contains adequate amounts of organic matter, 6 to 8 percent humus, there is ample amounts of Nitrogen even when a soil test shows a lack."

Bagged garden soil is more fertile than potting soil since black peat is #1 ingredient in garden soil in the midwest, and black peat is black humus & higher in nitrogen.

Your formula of garden soil + native soil + manure compost for pots give amazing roses !!

There's a poster Tique Lo in Utah who posted the best Pink Peace in a pot (with lots of petals & pretty ruffles), he mixed his clay with pine-barks and used that in pots.
