The In-Depth Guide To Growing Clematis in Pots

Clematis is one of the plants every gardener should grow at least once during their lifetime.

It’s a real pleasure doing so and growing clematis in pots can be a lot of fun.

If you already have one in your garden, then you’re probably looking to squeeze in another one to add to the beauty of your place.

Growing Clematis

Clematis crops are really tall, a bushy vine that takes a lot of space.

If you grow your Clematis in a garden, that’s good, it won’t require that much attention. But, Clematis grown in closed spaces such as a small pot or container will need a lot more care and attention from you.

If you know little about this plant or nothing at all, then you’re in for a treat as we’re about to dive in real deep in explaining what should be done when growing this crop.

Selecting a Plant

A few years ago, you could only find the plant in some traditional flavors such as:

Jackmanii, Henryi, General Sikorski, and Comtesse de Bouchard.

But because this plant has become so popular, you can find dozens of more flavors at every garden center near you.

When choosing a Clematis plant, think about height, flower form, and color.

Pick a Clematis plant based on how long the vine you have is. They range between 10 and 20 feet, and there are even smaller ones that can fit in a decorated pot on the patio.

A standard Clematis flower form is a large blossom with around 6 petals that measure 5 to 6 inches across.

You can also find Clematis plants with smaller blossoms, or even double blossoms sometimes.

Colors range from white to wine red, lavender to purple, and some yellow ones, too.

Where to Plant it

You should plant these plants somewhere sunny because they need at least 6 hours a day of sun time.

They grow better in moist, well-drained soil that has a slightly neutral pH level. You should dig a good hole for it, and use a lot of compost and some granular organic fertilizer.

Be very gentle when planting it, because the roots are very fragile.

Put the plant a little deeper than how it was in the pot making the first set of true leaves just under the soil.

Water the plant once a week for the first season. Once it survives through its first year, it will probably grow and thrive.

Don’t forget to put mulch a few inches away from the crown to conserve moisture.

Make sure the plant’s roots are in the shade and its foliage is in the sunlight.

How to Support it

Clematis is a climbing type of plant, which means it needs something to hold on to, if not it will stop growing.

So, make sure you provide something that isn’t any wider than a half-inch in diameter. Something like twine, fishing line, and wire.

You may also need to do some trussing during the season to help support the vines and keep them attached to the trellis. Using the fishing line and twine would work perfectly for this.

Pruning & Caring

Clematis vary in how much pruning they need. You might want to avoid pruning them during the spring if their vines last for a year.

Keep this simple rule in mind: leave last year’s growth until mid-spring, and start pruning only when you’re able to see which vines are dead and which are starting to leaf out.

Steps To Growing Clematis in Pots

If you live especially in a climate with chilly weather, then Clematis will perform best in large containers.

Growing Clematis in pots require filling the container with good quality, lightweight potting soil, then mix in a general-purpose, slow-release fertilizer.

Right after planting the Clematis, install a trellis or other support for the vine to climb and don’t wait until has established itself because this may damage the roots.

Caring for Clematis in Pots

If you plant the Clematis plant in a container then it will need regular irrigation since potting soil dries pretty quickly. You should also check the plant once a day, especially if the weather is dry and hot.

You should soak the potting mix whenever the top 1 or 2 inches start to feel dry.

The fertilizer you use with the Clematis plant will provide it with the nutrients it needs to bloom throughout the season.

Depending on your preferences, you can feed the plant once every two weeks using a water-soluble fertilizer mixed according to label directions.

During winter, if the Clematis is healthy then it wouldn’t require all that much protection. Although some varieties are more cold hardy than some others.

A layer of mulch compost is more than enough to protect your plant if you live in a cold area. You can also move the pot into a sheltered corner or near a protected wall for more protection.
