Clematis will grow faster when you give them the right balance of sunlight, deep watering, proper feeding, and consistent pruning.
If you’ve been staring at a vine that seems stuck at the same height for weeks, you’re probably wondering how to get clematis to grow faster, and the good news is that most slow growth is fixable.
These climbers aren’t naturally sluggish, they just have specific demands that, when ignored, make them sulk.
In this post, I’ll walk you through the exact steps to get clematis growing faster, from planting depth to fertilizer timing, so you can finally see that explosion of vertical growth you’ve been dreaming of.
Let’s dig in and turn that stubborn vine into a vigorous climber.
How To Get Clematis To Grow Faster: The Core Formula
The secret to getting clematis to grow faster is mimicking their native woodland conditions, which means cool roots, warm sunny tops, and rich, moist soil.
When you nail these three things, your clematis will respond with rapid new shoots and a cascade of blooms.
The most common reason a clematis grows slowly is that it was planted too shallowly or it’s sitting in soil that’s too dry or too hot.
So let’s break down the exact techniques to get clematis growing faster in your garden.
1. Plant Deep For Instant Vigor
If you want to get clematis to grow faster, you need to plant it deeper than almost any other vine.
When you plant a clematis, bury the crown (where the stems meet the roots) at least 3 to 4 inches below the soil surface.
This deep planting encourages the vine to produce multiple stems from below ground, which gives you a bushier, faster-growing plant.
It also protects the crown from frost damage and disease, which can otherwise stall growth completely.
If you’ve already planted your clematis at soil level, you can gently mound soil or mulch over the crown this fall to encourage faster growth next spring.
2. Give It “Head In The Sun, Feet In The Shade”
To get clematis to grow faster, you need to understand that they’re paradoxical plants.
They want their flowers and leaves bathed in at least 6 hours of sunlight daily, but they absolutely hate having hot, dry roots.
If your clematis is baking in full sun with bare soil around its base, the roots overheat and the vine stops growing altogether.
So, plant low-growing perennials or place a flat stone at the base of your clematis to keep those roots cool and shaded.
This simple trick can accelerate growth significantly because the plant can focus on shooting up instead of just surviving heat stress.
3. Water Deeply and Consistently
Another key to getting clematis to grow faster is deep, regular watering, not just a light sprinkle every evening.
Clematis roots are greedy and will reach deep into the soil, but they need that moisture to be available consistently.
During the first two years, water your clematis thoroughly twice a week, soaking the soil to a depth of at least 12 inches.
If you let the soil dry out completely, even once, the vine will pause its growth for weeks as it recovers.
Use a soaker hose to deliver water directly to the root zone, which will definitely help you get clematis growing faster without wasting water.
Feeding Your Clematis For Maximum Speed
If you’ve got the sunlight and water right, the next thing that determines how to get clematis to grow faster is nutrition.
Clematis are heavy feeders, and a hungry vine will sit there looking healthy but never actually grow.
You don’t need a special fertilizer, but you do need the right timing and type.
1. Use A Balanced Fertilizer In Early Spring
When new shoots first appear in early spring, that’s your signal to feed.
Use a balanced, slow-release fertilizer like a 10-10-10 formula, and sprinkle it around the root zone, not directly against the stems.
This gives the vine a steady supply of nitrogen, which fuels those rapid green shoots you’re chasing.
Feeding too early or with a high-nitrogen food can cause soft, weak growth, but a balanced meal in spring is perfect to get clematis to grow faster.
2. Add Compost As A Mid-Summer Boost
Around midsummer, if your clematis has slowed down again, top-dress the soil with a couple of inches of well-rotted compost.
Compost acts as a gentle, slow-release tonic that revitalizes the soil food web and encourages a second flush of growth.
This works especially well for large-flowered hybrids that tend to get tired after their first big bloom.
Just spread it over the root zone and let the worms do the work.
3. Avoid High-Nitrogen Overload
While you want to get clematis growing faster, you don’t want to feed them so much nitrogen that they produce only leaves and no flowers.
Skip synthetic lawn fertilizers that are high in nitrogen, as they’ll give you a giant green mess with zero blooms.
Stick to organic, balanced feeds or ones specifically formulated for flowering vines.
And always water the fertilizer in well so it reaches the roots instead of evaporating.
Pruning Strategies That Unlock Fast Growth
Many gardeners are scared to prune clematis, but getting the pruning right is one of the best ways to get clematis to grow faster.
Pruning doesn’t hurt your vine, it actually forces it to push out more vigorous new basal shoots.
If you don’t know your pruning group, just watch when your clematis blooms and go from there.
1. Hard Prune Group 3 Clematis Every Spring
If your clematis blooms on new wood (usually late summer or fall), you can cut it down to about 12 inches from the ground every late winter.
This brutal haircut sounds scary, but it’s the absolute best way to get clematis to grow faster, because every node left produces a new shoot.
You’ll end up with a much bushier plant that scrambles up your trellis at double the speed.
2. Light Prune Group 1 and 2 Clematis
For early-flowering types that bloom on old wood, don’t cut them down hard or you’ll lose flowers.
Instead, just remove dead stems and lightly trim back to a pair of strong buds right after their bloom finishes.
You’ll still encourage new growth, and the vine will reward you with a faster, tidier climbing habit next season.
3. Deadhead Spent Flowers For Energy Redirection
Once blooms fade, snip them off with a few inches of stem.
This stops the plant from putting energy into making seeds and redirects all that power into extending the vines.
This one simple habit can genuinely help you get clematis to grow faster each season.
So, How To Get Clematis To Grow Faster?
You can get clematis to grow faster by planting it deeply, keeping roots cool, watering deeply, feeding balanced fertilizer, and pruning according to its bloom time.
Remember that this vine is a marathon runner, not a sprinter, but with these conditions, it will turn into a sprint.
Check your soil drainage first, as waterlogged roots will stop growth no matter what you do.
And always be patient for the first year, which is often spent establishing roots, then magic happens in year two and three.
If you’ve been wrestling with a lazy clematis, go give it a deep soak, a cool mulch blanket, and a light trim, and watch how fast it rewards you.
Happy growing, and I hope your fence is covered in glorious clematis blooms in no time.
