How To Care For Alstroemeria: 4 Tips To Keep Them Longer

If you’ve ever received a bouquet of alstroemeria, you’ll know just how cheerful and elegant these blooms can be. Sometimes called Peruvian lilies, alstroemeria flowers are full of charm with their vibrant colours and unique markings. 

But how do you keep them looking lovely for as long as possible once they’re in your home? That’s where how to care for alstroemeria becomes important. Whether you’ve received a delivery from a friend or picked up a bunch for yourself, this guide will help you keep your flowers looking fresh and happy for days.

Let’s explore some down-to-earth ways you can give your alstroemeria the love it deserves.

1. Trim The Stems Right Away

The first and most important step is trimming the stems. Use a sharp, clean pair of scissors or garden shears to cut about 2 to 3 centimetres off the bottom of each stem. Make sure you cut at a 45-degree angle rather than straight across. 

Why? An angled cut increases the surface area that can absorb water, which means your flowers get hydrated more efficiently.

Also, avoid crushing the stems by using blunt tools. Damaged stems struggle to take in water properly, which can lead to drooping much sooner than you'd like. And if the flowers have been out of water for a while during delivery, the ends may have sealed themselves, so a fresh cut helps reopen those vessels.

2. Remove Any Leaves Below The Waterline

As you’re preparing your alstroemeria for the vase arrangement, take a few moments to check the leaves along each stem. Any leaves that would end up sitting below the waterline in your vase should be removed — gently pluck them off by hand or use your scissors if needed. Submerged leaves decay quickly and can cloud the water, turning it into a breeding ground for bacteria.

This bacteria doesn’t just look unpleasant, it can actually clog the stem ends and stop your flowers from absorbing water properly. 

3. Clean Your Vase Thoroughly

It might seem like a small thing, but a clean vase can make a world of difference. Even if it looks visibly clean, leftover residue from previous arrangements, especially cloudy water or slimy film, can introduce harmful bacteria to your fresh flowers.

Give your vase a good wash with warm water and a bit of dish soap. Use a sponge or bottle brush to reach all the nooks and crannies. Rinse it out completely to remove any soap residue before filling it with clean water. 

If you want to go the extra mile, you can sanitise the vase using a splash of white vinegar or a tiny bit of bleach (rinse thoroughly afterwards, of course). 

4. Use Fresh, Cool Water

Once your vase is clean and ready, fill it about halfway with fresh, cool tap water. Avoid hot or warm water, as it can stress the flowers and shorten their lifespan. Cool water helps the stems stay firm and crisp, which supports the blooms properly.

If your bouquet came with a sachet of flower food (which many do), be sure to mix it in according to the instructions on the packet. Flower food isn’t just a gimmick; it contains a mix of nutrients, pH balancers, and bacteria inhibitors that help your flowers stay fresher for longer. Stir the solution until it’s fully dissolved, then place your trimmed alstroemeria stems into the water.

Remember to change the water every 2 to 3 days. Each time you do, rinse out the vase, add fresh water (and more flower food, if available), and give the stems another slight trim, about 1 centimetre. These small, regular touch-ups can really stretch the life of your alstroemeria.

Extra Tips For Alstroemeria Care That Make A Big Difference

Keep An Eye On The Water Level

These flowers are thirsty. Make sure the water level doesn’t get too low and top it up if needed. Always keep the vase about halfway full.

Remove Wilting Blooms Promptly

As flowers naturally fade, remove any that look tired. This helps the rest of the bouquet stay fresh and prevents bacteria from spreading.

Don’t Refrigerate Them

Unlike some cut flowers, alstroemeria doesn’t do well in a fridge. Keep them at room temperature instead for best results.
