Caring for a lavender patio tree is all about giving it plenty of sun, sharp drainage, and a little tough love.
If you’ve ever wondered how to care for a lavender patio tree without killing it in a month, you’re in the right place.
These fragrant beauties look high-maintenance, but the truth is they thrive on a bit of neglect.
In this post, we’ll walk through everything you need to know about lavender patio tree care, from watering and pruning to overwintering and dealing with pests.
Let’s dig in.
How to Care for a Lavender Patio Tree: The Basics
Learning how to care for a lavender patio tree starts with understanding where it came from.
Lavender is a Mediterranean plant, which means it loves hot, dry summers and rocky, well-drained soil.
A lavender patio tree is simply a lavender plant trained onto a tall stem with a rounded canopy on top.
Because it grows in a pot, it depends on you for everything, so getting the basics right matters.
1. Give It All the Sun You Can
Lavender patio trees need at least six to eight hours of direct sunlight every single day.
Place your pot in the sunniest spot on your patio, ideally facing south or west.
If your lavender patio tree doesn’t get enough light, it will grow leggy, produce fewer flowers, and become more prone to disease.
2. Use Well-Draining Soil
The number one killer of lavender patio trees is soggy roots.
Use a gritty, well-draining potting mix, ideally one made for succulents or Mediterranean herbs.
You can even mix in some coarse sand or perlite to improve drainage further.
3. Water Sparingly
When it comes to how to care for a lavender patio tree, watering is where most people go wrong.
Let the top inch or two of soil dry out completely before watering again.
In summer, that might mean watering once or twice a week, while in winter you might water only once every two or three weeks.
Pruning Your Lavender Patio Tree
Pruning is essential for keeping your lavender patio tree looking neat and blooming well.
1. Trim After Flowering
The best time to prune is right after the first flush of flowers fades, usually in late summer.
Cut back about a third of the green growth, but never cut into the old woody stems.
2. Shape the Canopy
To maintain that classic lollipop shape, lightly trim the canopy into a rounded ball.
Regular shaping keeps your lavender patio tree compact and encourages bushier growth.
3. Remove Spent Blooms
Deadheading throughout the season keeps your lavender patio tree tidy and can even encourage a second round of flowers.
Just snip off the faded flower spikes with a pair of sharp snips.
Overwintering and Common Problems
If you live somewhere with cold winters, overwintering is a big part of how to care for a lavender patio tree.
1. Protect It From Frost
Lavender patio trees are often less hardy than lavender in the ground because their roots are above ground in a pot.
Move your tree to a sheltered spot, like a garage or conservatory, before the first hard frost.
2. Watch for Root Rot
Yellowing leaves and a mushy stem usually mean root rot from overwatering.
If you catch it early, repot your lavender patio tree in fresh, dry, gritty soil and cut back on watering.
3. Deal With Pests Quickly
Spider mites and whiteflies can occasionally bother a stressed lavender patio tree.
A strong blast of water or a little insecticidal soap usually takes care of them.
4. Feed Lightly
Lavender patio trees don’t need much fertilizer.
A light feed in spring with a low-nitrogen fertilizer is plenty, since too much nitrogen means lots of leaves and few flowers.
So, How Do You Care for a Lavender Patio Tree?
To care for a lavender patio tree, give it full sun, gritty soil, and sparse watering, then prune it after flowering and shelter it from frost.
It really is that simple once you understand what this Mediterranean plant craves.
Get the fundamentals right and your lavender patio tree will reward you with silvery foliage and fragrant blooms for years.
So whether you’re a first-time grower or adding another lavender patio tree to your collection, these tips should keep it happy and healthy.
Enjoy your gorgeous, low-fuss lavender patio tree.
