A lector sent in a interrogative sentence last week that I thought was worth sharing and mouth about . Here is the question .

“ adept morning . I live in middle TN , corpse soil galore . I had two knock out roses that were huge that I dig up and give to a friend and plan on putting an Austin rise in their piazza . Amended the soil a fleck with compost , have my own tooth root little David Austin rose , planted it , used the constitutional fertiliser the rosarians employ around it , mulched with pine needles . It has not maturate at all , well , one cane grew about six inches and that was it . It stick green and good condition otherwise . My instincts tell me test the soil but my brain say , well the knock out rose grew like gangbusters there . What would be your opinion on why not so much maturation ? ”

As we come into rose purchasing time of year what is bechance to this reader is deserving speak about because more and more of you are probable to be perplexed by the very same situation .

Why ?

More and more roses are being offered as own - root rose and more importantly being produce and sold as own - source rose wine grown in pots . These are very different from the budded bareroot lusus naturae you might be used to . Not only in sizing but in how they behave in their first season or two .

Budded ( or grafted ) roses are grown by bud a small piece of the trust rose on to a rootstock or understock . The rootstock is chosen precisely because it is vigorous and will help push the rose wine in terms of growth . This is how some rose that were not particularly solid growers made it into your garden . The rootstalk made up for the lack of muscularity in their growth .

But more significantly to our question is the fact these bud roses were grown in subject field for a two full years before they were sell . That intend you were not buying a youthful plant but in fact buy one that is two years old with a reasonably mature root and cane complex body part .

Own radical roses are grown by taking a cuttings of the desired jump and rooting them in land in a glasshouse . Once ascendent egress these cuttings are then transplanted to large stool and that scope from a band deal ( about 3”x6 ” ) to a full sized 3 - gallon . Generally the pink wine are rise on for anywhere up to six to ten calendar month and then sold .

This means the own root move up you purchase is less than one year old as opposed to the budded rosiness that is two positive years old . And the latter were grow in a theater of operations which does yield more matured root organization .

So the answer to the reader ’s question has nothing to do with what they are doing in terms of guardianship or even with the variety of arise embed . It has to do with the fact the Knockouts she planted were likely subject area grown / former plants when she got them . The Austin rose is unseasoned and will take more meter to get found . I ’ve grown dozens of dissimilar Austin uprise over the years on their own roots and I know they are vigorous by nature and the readers will quickly catch up and thrive .

I also know from personal experience that give time to catch up to the age of the field grown roses when they were plant ( two years old ) our reader will never live the difference .

My answer is that the reader is doing nothing incorrect and in fact doing everything proper .

Once again prove one of the major keys to gardening is patience !

Coming up . Is their a midway ground ? ? ?
