New Stem from Soil Up

5 months ago

Some of my roses throw out nice thick stems....that I don't hesitate to deadhead in the same season.

For others, like in this post. I have a new growth, soil line up. Is there any benefits to not deadheading this at all after the 1st flush if I want this stem to just grow as vigorusly as it can for this growing season /

A basal growth is one which emerges at ground level from a rose's crown. A lateral growth is one which emerges from an existing cane. They all theoretically end with flowers at their tips. When the tip's flower, or last flower finished blooming (if it was a cluster of blooms), drops its petals, that stem below is just about as thick as it will get. There will be some additional diameter increase of that stem over time. This increase in diameter is more true of basal canes which eventually become woody as they slightly increase in diameter over their lifespan. Their vigor and ability to support lush top growth diminishes every year as they get older and woodier.

Watch that tip. If it terminates into flower buds after the flowers are finished blooming, I would dead head the cane. Do it to a point where new growth made below your dead head cut comes from a spot on the cane that appears to be thick enough to support husky new growth.

If it terminates in blind growth, leave it be. Let it build up strength and substance, but if it starts making lateral new growth near the tip because of apical dominance, cut it back as if you were dead heading it as outlined above.

What I'm trying to say is that if leave a new basal growth alone....don't deadhead, so a side shoot emerges, will that new basal growth (bad analogy but apical dominance) remain at the new tip and just keep on growing longer for the season. Cause I don't care about a 2nd or 3rd bloom on the new basal growth. I just want it to focus on extending it's growth and girth for this season....so I have one nice new healthy cane for the following year

Yes, apical dominance rules. The dormant/sleeping bud highest up any stem, especially a green, current year basal stem, gets the message to break dormancy and grow.

I misworded it....meaning, I don't want a dormant bug highest up the new stem to grow. I would want the new stem to continue growing vert and focus all -energy- on growing vert and thicker in the same season

What rose variety are you talking about? What is your agricultural zone, and closest major city? Supplying this information will help me help you.
