Are these rootstock growth???

2 years ago
last modified: 2 years ago

I bought a Florentina grafted rose this spring and recently I see some new shoots came up from the bud onion which is at the ground level, not buried . They grows very fast and look different from the original Florentina branches. So I'm not sure whether they are new growth of Florentina or of the rootstocks (which then need to be removed). Please take a look at the pictures and help me identify them!

Thank you!


These are the 4 shoots:


They come out from the bud onion so I dont know ???




Look, the new branch is big and straight vs. Florentina's branch is small and kinda zigzag:

So what do you think?

    Looks like it is now sending out it's mature cans. Those spindly canes are juvenile.. Florentina has very thick Games That need cane that need gently bending

    If you garden in zone 7 or colder, you are going to have problems with an unburied bud union during winter, I think. I live in zone 7 and still bury the graft. Diane

    Good photos. Did you do some excavation for photos 2 and 3?

    Good arrows.


    “They come out from the bud onion so I dont know ???“

    Is that a statement masquerading as a question?

    4 new basal canes from the bud union, top graft (Florentina scion), not from below it, and all in one year! That's phenomenal! Congratulations! Start planning its support. Those canes will need to be tied to it come spring, 2025. You may get blooms all over those 4 basal canes from lateral growth made in the spring. If not supported, everything will sprawl upon the ground.

    My Florentina is self supporting here and does not sprawl particularly. The canes are stiff and strong.

    Vanessa,

    Where do you garden: zone, state, and city, if you please? Also, is your soil sandy? Finally, what fertilizing program do you implement to get such great growth?

    Sheila, Mine is also stiff cane, but they will bend and form an arching shrub if not supported. I love this rose

    Mine does arch gracefully Vapor, true.

    Thanks everyone for replying. I'm so happy these 4 are from my Florentina. It's time to plan the support now, so excited!

    @Diane: Thank you for the advise! This Florentina is my first ever rose that I bought and planted before I know the different between grafted vs own root, and buried vs. exposed bud onion. I'm in zone 5b so I'm planning to put more soil and mulch to cover the bud onion later in the season and probably prioritize purchasing own-root roses next time.

    @Moses: I learn a new thing today: basal cane vs. sucker. Thank you! I'm in zone 5b, Colorado area. I planted this rose late May this year; so it is about 2 month so far. Here is what I have done:

    My soil is clay soil so before planting I amended with compost cow manure and worm casting. First 2 weeks after planting, I watered it every 2 days with half of a B1 pill dissolved in the water every time. End of June, I gave it fish fertilizer; and also buried into the surround soil some massed eggshells, shrimp shells, banana peels, and coffee ground.

    I'm planning to use fish fertilizer once a month till end of fall for this year and switch to granular rose food next year. Hope it will go well!

    Let me know if you have any other recommendations. Thank you!

    So for this Florentina, do you suggest me to dig it up and plant it deeper, or should I just put extra soil to cover the bud onion?

  • 2 years ago

    I might add more soil on top of the crown this Fall, rather than dig it up to replant.

    There is a tendency for a rose to 'sink' deeper over the years. This sinking is due to soil settling after planting, and the rose going along with the sinkage. Then there is the probability that your bush's proximity to your house will afford it more winter protection than if it was planted further out. As you mulch the soil around the bush the mulch decomposes, adding to the depth the crown of the rose is situated under, over years to come. Climbers, as Florentine is, are usually hardier than the average among the families of rose types.

    I wrote all this to advise you to leave the bush be, as it is where it is planted. You can easily add more soil in the fall to the crown as Sheila recommended, and (my additional thoughts), to 12 inches out from Florentina's crown, also.

    Remember too that Florentine is an ADR winner, and as such has passed some pretty rigorous survival trials, and proven its merit. It should show a lot of health and vigor for you.
