Climbing rose blind canes

Hi all, new gardener here, have planted two climbing roses in a long planter under the edge of my deck the latter part of last summer. One is a Don Juan climber that is blooming like crazy this year. The other is an Eden Rose climber that is mostly sending up blind canes with (so far this summer) only one bloom on a fairly thin branch towards the bottom of the plant. I read too much nitrogen can lead to no blooms but the Don Juan is in the same planter so. Is it just that this is the first year? Any advice?

    If you allow the canes to grow straight up, all you'll get is a bunch of flowers right at the top of each cane. Flowers form at the top most point of the plant.
    What you need to do is to bend the canes horizontally and tie them in to the framework.
    When you do that, the whole cane is at the same height so there is no top and flowers will appear along the whole length of the cane.

    If I get a blind stem I just prune back to a leaf or 2 below. That should cause a new shoot to develop.
    But most important is to get the canes horizontal for lots of flowers.

  • Ok I have pulled them all horizontally and tied them with twine - only one broke. Hope this works and thank youuuu.  Looks like I may need to add some additional trellises or prune the canes back at the end of the season, but we will see! Thanks again

    Along with @Pete.8 helpful advice @shariloeHJ4ZDVMY, there's a dedicated rose thread on the forum, populated by some very knowledgeable growers, so if you have any problems or need advice in general with your roses, have a look there.  :)

    This is a link to the thread - it gets updated 'seasonally' , but the girls usually do a link when it changes

    Hello and you are very welcome to join the girls (and boys and any other gender you care to add!) on the Rose thread.

    What strikes me immediately is that you have one rose too many for that space, either can grow canes 3-4 metres long. In fact, I’ve seen Eden grown up and right over a 4m high and wide arch! To do just one justice and not be constantly fighting it with your pruners, you do need to gently and gradually (to avoid breakages) bend the canes near horizontal to get lots of flowering lateral shoots all along as Pete says. For that you need space.

    Personally, I would consider relocating Don Juan in winter. I’ve heard it said that the Don’s blooms are best appreciated from above, so is there a space you could plant it below your deck and grow it as a pillar rose? That way, you can train Eden all along and even wrap around the front of your balcony balustrade, enjoy the Don from above and not worry too much about espaliering his canes.

    Climbing roses do need around 3 years to reach their full size and blooming potential and Eden in particular is known as a rather shy bloomer to start with. Both of yours are actually doing really well for first year roses 😃

  • Gosh thanks for the advice! (Believe it or not there’s also a lovely purple clematis between the two so we got lotsa flowers in the one planter. See pics from earlier this spring; no blooms now, but I did prune the clematis and it looks like it’s heading for another round ….!) Both roses did surprise me with their enthusiasm, in just a few months! and I had been starting to think I had planted them too close.  I could definitely move the Don Juan to the bed at the front of our deck at the back edge of the bed with some new trellises to guide it … 🤔 
  • Ok sooooo I did start getting more shoots along the top of the long cane that I bent per Pete.8’s advice, but still no buds. So have fertilized - I had used compost only plus some bone meal when I put in the plants, and added some again this year early, but never fertilized. Maybe the Don Juan is just too greedy and getting it all?

    As for moving the Don Juan per Nollie’s suggestion - since I posted it has started coming up over and through the railing so I am getting some beautiful top views. I do have one additional trellis to train it to the right to start wrapping it around the front, and thinking to add one on the left of the Eden climber and train it along the steps. But I will think on moving it… there definitely is space in the middle of the bed in front of the deck where I am allowed to plant, behind some spiria that will provide nice shade for the roots…

    Looking good.
    It'll be next year that all the flowering buds appear on the horizontal canes - it'll look FAB
    Train any new canes that come from the ground in a similar manner then when you get too many canes prune out the oldest as near to the ground as you can - that'll keep it all looking fresh.

    Mine would too if I followed that advice 🤣
