Clematis

I have a 4-year-old clematis that is not getting any bigger. It blooms beautifully (once) in late spring, then it is done for the season. It has a short trellis to climb and it is fairly bushy. Do you think a taller trellis would help?

Have you fertilized it? If not, then fertilize with a 3:1:2 or 4:1:2 ratio fertilizer. You may also want to consider pruning, as this can oftentime promote growth. This article may offer additional help as well: http://www.gardeningknowhow.com/ornamental/vines/clematis/growing-clematis.htm

Clematis Won’t Bloom

I have had my clematis for three years. It grows every year and climbs the arch but I have never had a bloom on it. What can I do?

It may be lacking phosphorus. I would give the plant some phosphorus, like bone meal. If the foliage looks healthy but there are no blooms, phosphorus is normally the problem. This article should also help: http://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/phosphorus-plant-growth.htm

Transplanting a Clematis

I have a Duchess of Windsor Clematis that I would like to transplant. It has not started to bloom, although it does have buds on it. We live on the coast in Ct. Is it too late to do this?

You can transplant now, but if you do, it most likely will not bloom this year. Moving is hard on a plant and it will sacrifice its blooms in order to focus on recovering from being moved. You might be better transplanting in fall. The plant should recover enough by the next year to bloom for you.

Growing Vines Up Posts

I have 4 plants, 2 jasmine and 2 clematis, that I want to grow up two different 8 foot posts to an 18 inch wide, 15 foot trellis. How do I get the plants up the posts? Ideas I’ve had (wrap the post with chicken wire, buy two of those cheap 15 inch x 6′ trellises from the hardware store and somehow attach them to the posts, hang some wire from the top and loop it around–this is the most invisible idea I’ve had, but not sure how to make it work) are either ugly or questionable.

I would use bird netting instead of chicken wire. It is nearly invisible once the plants are on it and can simply be stapled on. You can find it at the hardware store as well.

What Would Be Cutting Just the Clematis Off

The last two years I have been watching my clematis being cut off at the ground level. They do not eat the plant, they just get cut off. I am not able to find anything. They do not eat my morning glories. Help please. I don’t know what to do.

ANSWERS

If the damage is on new growth at or near the soil line, it could be cutworms, which normally feed at night (their daylight counterparts are called loopers). During the day they hide in the soil or leaf litter below. Treat the plants with neem oil and this should help. Here is more information: http://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm

Clematis

I have a clematis that grows beautiful leaves and shoots each spring but has yet to bloom with flowers. Last year we had two blooms and the year before none at all.

ANSWERS

It likely has too much nitrogen. It makes the plant grow lush but with few flowers. Try adding bone meal. This will add phosphorous and balance out the nitrogen. Also, if there is lawn nearby that you fertilize, try not to do it near the clematis.

Here are some other possibilities:

Splicing a Broken Clematis

I accidently cut 3 established clematis clean off near the ground whilst tending roses. Is there a way to re-join the broken runners?

Unfortunately, you cannot splice them back together, but you may try rooting the cut sections. This article will help:
