To do a search in a specific forum, go up to the search bar at the top of the forum you want to search, type in the term you want to search for, and then wait briefly. The first option in the list that pops up will be for the term in the current forum, and you click on that. It isn't an obvious set of steps - took me some trial and error to figure it out since the default is to search all of Houzz if you just push enter after typing your search term.

I would probably enjoy the first set of blooms and then cut it back and plant it shortly after the blooms end. That will let it start settling in and growing, perhaps setting buds for next spring. For type 2 (blooms on old and new wood so light prune) or type 3 (blooms on new wood) it is usually recommended to hard prune the first year or two, but I am not sure what to do with type 1s. Mine are all C. macropetala or alpina and they grow so rapidly that I haven't done the hard prune since they have lots of stems and roots without it.

Nice to see you posting, Vera.

I grow many type 2 and 3 clematis. This early I would plant it now leaving on the flower buds and not cutting the plant back until after they have bloomed. Since it is a large pot it likely has a large root system already. If more buds form you could even wait until the first flush has finished to cut back. In my zone 4 I like to plant it 4 inches deeper. Type 1s, bloom on old wood, are not hardy here. Type 2s, bloom on old and new wood, usually die back to the ground over the winter so are usually treated like Type 3s. The early flush of blooms are lost but the plants still bloom well a bit later.

When you plant, if there is green growth on many vines you can try to untangle them from the obelisk, cut them off the obelisk, or let them stay on the obelisk until you are ready to cut the vines back. I would want to see the bloom so would wait to cut back until after the bloom has finished. Also post again when it blooms, maybe someone might recognize it then.

Here is some info from the FAQ. It appears that some of the questions and answers are missing. There used to be one on planting. The info below was taken from transplanting and moving a clematis but is still pertinent

.It is best to dig and prepare your new location before you dig up the plant to be transplanted. Dig a large hole, and dig it deeper than needed to make some room for compost or rotted manure in the bottom. You will also want to plant the clematis two to three inches deeper than the old level. One can use a post hole digger tool to get a nice deep hole. It is best to bury one or two pairs of latent buds, leaves and all, so that the plant can sprout from under the ground. It becomes a good insurance planting policy. The buried stem will develop roots.

Before you place the plant into the new hole, throw in a handful or two of bone meal or other fertilizer high in phosphate to aid in root growth. ... Bulbtone, an organic fertilizer, can be added to the hole without fear of burning the roots. Mix the bone meal and fertilizer with compost in the bottom of the hole, fill the hole with water, and place the new plant in it's new home, submerging it in the water. Fill in around the plant with the best compost or enriched top soil you can find, and water it in.

Keep the plant well watered and fertilized the first few years until a deep root system capable of supporting the plant through dry times has had time to develop. It is best to mulch a large area around the base of the plant to keep the soil moist and reduce evaporation. Watering your plant is critical to its survival!
