How To Grow Lavender In Water

You can grow lavender in water, and it’s actually one of the easiest ways to multiply your favorite plants without spending a dime.
 
If you’ve ever wondered how to grow lavender in water, the good news is that this fragrant herb roots quite happily in a simple glass of water on your windowsill.
 
It’s a fun project that lets you turn a few snips from an existing plant into brand-new lavender babies.
 
In this post, we’ll walk through exactly how to grow lavender in water, the best cuttings to use, and how to avoid the common mistakes that make stems rot instead of root.
 
Let’s dig in.
 

How to Grow Lavender in Water

Growing lavender in water comes down to a few simple steps, and once you get them right, you’ll be rooting cuttings like a pro.
 
Here’s the process broken down so you can grow lavender in water successfully every time.
 

1. Take the Right Cutting

To grow lavender in water, you need a healthy cutting from a mature plant.
 
Choose a softwood stem that’s still green and flexible, not the old woody stuff near the base.
 
Snip a piece about four to six inches long using clean, sharp scissors.
 
Make your cut just below a leaf node, since that’s where new roots love to form.
 

2. Strip the Lower Leaves

Before you grow lavender in water, remove the leaves from the bottom two inches of the stem.
 
Any leaves left sitting in the water will rot and turn your glass into a murky mess.
 
Keeping the top leaves intact lets the cutting keep photosynthesizing while it works on growing roots.
 

3. Place It in a Glass of Water

Now for the easy part: fill a clear glass or jar with room-temperature water.
 
Stick the bare end of your cutting into the water so the node is fully submerged.
 
Clear glass is best when you grow lavender in water because you can actually watch the roots appear.
 

4. Find the Right Spot

When you grow lavender in water, light matters more than you’d think.
 
Place the glass somewhere bright but out of harsh, direct afternoon sun.
 
A sunny windowsill with soft morning light is pretty much perfect.
 

5. Change the Water Regularly

To grow lavender in water without rot, swap out the water every two or three days.
 
Fresh water keeps oxygen moving around the stem, which encourages rooting.
 
If the water ever looks cloudy, change it right away.
 

How Long Does It Take to Grow Lavender in Water?

Growing lavender in water isn’t an overnight thing, so patience is your friend here.
 
Most cuttings start showing tiny white roots within two to four weeks.
 
Some slowpokes can take up to six weeks, especially in cooler months.
 
If you’ve been waiting and wondering how to grow lavender in water faster, a little warmth and bright indirect light will speed things up.
 
Once the roots reach about one to two inches long, your cutting is ready for the next stage.
 

Common Mistakes When You Grow Lavender in Water

Learning how to grow lavender in water is mostly about avoiding a few classic pitfalls.
 
Here’s what tends to go wrong.
 

1. Using Woody Stems

Old, woody cuttings rarely root well when you grow lavender in water.
 
Always go for soft, green, flexible growth for the best results.
 

2. Letting Leaves Sit in the Water

Leaves submerged in water rot quickly, and that rot spreads to the stem.
 
Strip the bottom leaves before you grow lavender in water and you’ll dodge this problem entirely.
 

3. Skipping Water Changes

Stale water is a rooting killer.
 
If you forget to refresh the water, your cutting may never grow lavender roots at all.
 

4. Putting It in Direct Sun

Too much harsh sun can cook a delicate cutting before it roots.
 
Bright, indirect light is the sweet spot when you grow lavender in water.
 

Can You Grow Lavender in Water Forever?

You can grow lavender in water for a while, but not forever.
 
Water alone doesn’t provide the nutrients lavender needs to thrive long-term.
 
Once roots are a couple of inches long, transfer your cutting into a small pot with well-draining soil.
 
That said, many people do keep lavender in water for months just for the pretty roots and the lovely scent.
 
If you go that route, add a drop of liquid houseplant fertilizer every few weeks to keep it going.
 

So, Can You Grow Lavender in Water?

You can grow lavender in water, and it’s a simple, satisfying way to create new plants from cuttings you already have.
 
Just take a soft green cutting, strip the lower leaves, and pop it in a glass of fresh water on a bright windowsill.
 
Change the water every few days, stay patient for a few weeks, and those little roots will show up before you know it.
 
Once they do, pot your new lavender up and enjoy that wonderful fragrance for seasons to come.
