I used to grow mine in containers. I used the 5.1.1 mix. Most of my pots were 15 gallon plastic injection molded with handles. I bought the pots from griffin greenhouse supply. Now that I have much more land, I put them all in raised beds. They are very happy. I highly recomend a plant dolly for all your containers. I still grow lots of stuff in containers. I made the soil for all my raised beds, so I didn't even have to mess with my soil. I have 15 bushes in 4 large raised beds made with 2x12s. I have northland,northblue,blueray,bluecrop,patriot,chandler,reka,elliott,earliblue,berkley,duke,jersey. This year was my first good size crop. All of these were highly recomended. Some are sweeter than others. Mike said his tasted awful."Hi Mike" All of these get full sun, that blueberries need. Northland,berkley,duke,bluecrop are very sweet. patriot are tart, Chandler "the largest berry of all" are not that sweet. Elliott are tart but they produce so late they are worth it. I am still getting fruit off the elliott. The tart ones you can use for pies. I would like to add more. Duke would be my first choise. I just thought I would add my experience. Good luck Joe. Filix.

I grow garlic in 18" containers for clean seed. I grow the main crop in raised beds and the virus load gets too high and the crop starts to show signs of distress so this year I decided that I could probably clean up my seed stock by growing in completely clean soil. I have always grown in containers when I want to preserve a strain, but do not want to commit to a large bed of them. When I checked they yesterday I could see roots just busting out of the drain holes--they might be a bit more work as far as watering and feeding goes (takes more of each), but the results are really worth it to me.

Yes, it can be grown in a container - I have several clematis in pots growing on my deck. How large a pot depends a good deal on the type of clematis - some clems are bred specifically for this purpose and are quite compact plants. But other clematis can get to be large vines and will develop a root system to match. These need a generously sized container to accommodate their larger root system. My larger vines are in containers that are about 24" deep and about 18" across at the top with a slight slope to the base - like an oversized flower pot. You want a good textural, fast draining potting mix and add some CRF like Osmocote. In zone 7b, there is no reason to assume this container could not stay outside all winter. The large flowered hybrids are hardy to z4, so quite able to withstand the cold if in a generously sized container and z7 soils seldom freeze to any appreciable degree anyway. It would be more a matter of the durability of the container - if you use a plastic or plastic resin pot or a freeze proof glazed ceramic container, you are good to go!

The simple answer is - you water slowly and watch what happens. I have a couple of Aralias in 18" diameter terra cotta pots. I water and wait. If there's no water in the saucer, I water a bit more and wait again. This is repeated until there's some water in the saucer. Usually, by the third time around, I'm done. In truth, I'm not really waiting. I go off and water other plants and just come back check the ones that don't have any water in their saucer.
