So what are clems supposed to do in the fall?

17 years ago

Hello,

it's my first year growing clems, and I managed to acquire 11 of them through spring and summer.

Some are type two, some type three.

Some flowered a little in the beginning of the summer, some did not. After that all of them did NOTHING through the summer.

Now, when the weather got cold ( about 40F at night) they are swelling their buds and some put on new growth. I thought that type two flowers again in the fall, but will this really happen ? It is so late in the year, the trees are losing their leaves, is this normal behaviour for clems?Why are they growing now, when there's no point in growing any more, because winter is coming?

I have a few that did zero growth since I bought them and now they are still sitting there doing nothing, will the survive?

I also purchased a sorry looking Henryi a month ago, I potted in a 3 gallon deep narrow container, does it need to be burried for winter?

Thank you, sorry if the questions are dumb

    Don't be concerned if your young clematis don't do anything much flowerwise or growthwise since they were just planted this year. Clematis take several years to get established and are concentrating on their root development so that they can reward you in subsequent years with their flowers. They are not immediate gratification plants. Patience is the key with them.

    As to whether your type IIs will flower again, it all depends on the weather and how nice it stays before your first killing frosts. Plenty of my clematis that browned out this summer during the heat and lack of rainfall have begun putting out new growth since the weather has cooled and we have been getting rainfall. This is typical for any plant because this weather is similar to what they experience in spring--they are just responding to the weather conditions. There is nothing you can do to keep them from responding to the weather. I am just taking a wait and see attitude to see what happens with them and whether I will get any blooms this fall. If I do great, if not that is fine also.

    The Henryi will probably be fine in its container however burying the pot in the soil will help increase its chances of survival since I am not sure of the particular weather conditions you might experience in your gardening zone.

    I planted my first clems this year, some in February, some in mid summer, and some only recently.

    I've repeatedly cut all clems back throughout the growing season - within inches from the ground - to establish root growth per the advice of this forum.

    Some sat still for awhile after planting while others grew right away. One browned out completely, thought I lost it, only to find new growth has appeared within a months time.

    Others planted at the same time have already grown up to the top of my 4 1/2' fenceline. I stopped cutting them back at the end of July, and of the clems I planted in February, many of them have blooms now. Very pretty, just wish I could enjoy them on a warmer patio instead of this brisk weather.

    HF Young is blooming for me right now and Warsaw Nike has buds. If the warmer weather holds out a while longer, I should see blooms on it too. Harlow Carr never stopped blooming, and Madame Julie Correvon was without blooms for 2 weeks, but has more buds, a few should open soon. Huldine started growing like crazy a couple of weeks ago and I think it might be setting buds.

    Past years I've had blooms later in the season on Multi Blue, Arctic Queen and an unknown. The only reason I didn't have the second flush of blooms this year is I cut them back after the first bloom as an experiment.

    Same variety here Janet. I cut Duchess of Albany back 4 or so weeks ago and she is reblooming. One of my Blekitny Aniols has already rebloomed and is just sitting there. Kermesina is back up and growing. Ramona has already had more blooms. Addisonii has rebloomed for me three times now on one plant and the other plant is back up two feet tall. Betty Corning is back to 4 feet tall. Most of my type IIs look like H*LL like they normally do at this time of year. Some worse than others. Here is Proteus/Piilu--mostly brown with new green shoots developing in the axils if you look closely.

    The clematis on the wood and fencing arbor were cut back earlier and here is how most of them look. In the lower right corner you can see Hanajima reblooming and top and center my NOID reblooming with more buds forming along the whole length of the trellis. If you look closely behind the dark purple wandering jew plant you will see the browned out skeletonized leaves of my fremontii.

    Little Noid bloom up close.

    It truly seems once again that what happens to clematis in the fall depends on when they were cut back, the varieties involved, and whim.

    Thank you so much for answers and pictures!
    My type two's don't look like this, they are only a little brown at the bottom. None of mine were cut, except deadheading for the ones that bloomed. They stayed green, got eaten by earwigs, and have not grown. I couldn't cut some, because they were already 8 inch short and made of one stem only, but the roots looked big ( especially for how tiny the plant above is.... THey are all in amended heavy clay.
    Now they are swelling buds at the joins, and some make new leaves... I'll wait and see, and cut them all in the spring. But it would be so great if they were making at least one bloom!

    I think we missed one of your questions: Not all type 2's will bloom again in fall. To find out which ones, go to the link below and look up all your clems. Aside from that, you can't really expect much the first year. The second year, in comparison to the first, is better, but most clematis don't come into their own until the third year, some take 5 years to reach their full glory.
    In addition to that, I have found that group 2 clematis that typically rebloom in September won't rebloom if I cut them back. People in much warmer zones seem to get rebloom, but I don't.

    Also, you mentioned earwigs. Earwigs attacked the new growth on most of my clems this year. Those that were attacked the worst, which were group 3's, didn't bloom at all. The plants seemed to respond like they were constantly being pruned. Next year will be different, thought. As soon as the earwigs first appear, I'm spraying, regardless of how much as I hate to use pesticides.

    Oops, I see that Miguel did talk about the lack of blooming on new clematis. I understand how you feel, though. It can be somewhat frustrating when you first start growing clematis.

    Miguel, your Piilu looks so sad. My General Sikorski bloomed nearly all summer and then the entire thing wilted once it tried to grow again. In retrospect, I should have cut it back as soon as it put out a weird jumble of new growth all in one spot. The poor thing was probably exhausted from preforming so well over the summer and needed a rest.

    Yes, it does Janet. However it looked that way last fall and I cut it way back and it came back and went to town this spring with more blooms than I have ever had. Needless to say, I think you know what I will be trimming back severely again this winter! ;)

    I swear, clematis do what they want, when they want and there isn't a whole lot we can do about it. lol

    :) :) Janet you're right, clems really do what they want!

    Sorry to bug you again, but you meant to give me a link for type 2s, can you try to put it up again? I can't see it...
    if no link, maybe your knowledge can help me find which would be blooming in the fall.... what I have in type 2 is this:

    The president ( healthy, bloomed once)
    Elsa Spath (healthy, bloomed once)
    Dr. Ruppel ( lazy, just started some leaves)
    Warsaw Nike ( tiny sick twig)
    Miss Bateman ( tiny sick)
    Miss Curie ( tiny sick)
    Henryii ( purchased sick but started growing fast in container)
    Sunset clematis ( healthy, bloomed once)

    for type 3 I have Rouge Cardinal ( bloomed twice) and Pink Fantasy ( bloomed once)

    The earwigs were a nightmare throughout the spring and summer, but ever since I started a compost bin most of them seem to have moved in there....I hope that they never move out of there!

    then I got invaded by hideous huge slugs which ate all the daisy, dahlias and the hydrangea... and I can't mention here all the other pests that I found thriving in the backyard....
    I just ordered diatomaceous ( sp?) earth, to use next spring I heard it works well....
