Alstroemerias, also known as Peruvian lilies or lily of the Incas, are beloved for their vivid colours and long vase life. These cheerful blooms are a staple in many homes and flower vase arrangements, thanks to their beauty and resilience. But if you’ve ever found yourself wondering how to care for alstroemeria after receiving or buying a bouquet, you’re not alone.
At Windflower Florist, we’re often asked how to keep these flowers looking fresh and vibrant. Whether you’re decorating your dining table, sending love to someone across the city, or just treating yourself to fresh blooms, knowing a few simple tips for alstroemeria care can make all the difference.
1. Unwrap Your Alstroemeria With Care
The first thing to do when you receive your alstroemeria bouquet is to gently remove all packaging. Whether they come wrapped in Kraft paper, plastic, or tissue, it's important to let the flowers breathe. Handle them carefully to avoid bruising the petals or snapping the stems.
Some packaging materials can hold moisture, which may promote mould if left on for too long. Unwrapping also lets you inspect the blooms for any damaged stems or wilted petals that can be removed right away.
2. Trim The Stems At An Angle
This is one of the most important steps in alstroemeria cut flower care. Using sharp floral shears or scissors, trim 1–2 cm off each stem at a 45-degree angle. Why the angle?
It increases the surface area for water absorption and prevents the stems from sitting flat against the bottom of the vase, which could block water uptake. Always cut under running water or submerge the stems in water while trimming to avoid air bubbles that can block hydration.
3. Use A Clean Vase And Fresh Water
Before placing your flowers into a vase, make sure the vase is squeaky clean. Even a thin film of old water or residue can introduce bacteria that shorten your flowers’ life. Fill the vase with room-temperature water, not too cold or hot, and make sure it covers about half to two-thirds of the stem length. This gives your alstroemerias enough hydration without drowning them.
4. Add Flower Food Or A Homemade Alternative
Flower food isn’t just a bonus; it makes a real difference. Most bouquets come with a small sachet of flower preservative, and it’s best to use it all in one go. If you don’t have any, you can create your own solution with one teaspoon of sugar (for nourishment), a few drops of lemon juice (to balance pH), and a drop of bleach or white vinegar (to reduce bacteria). Stir the mix well before adding the flowers to ensure even distribution.
5. Remove Leaves Below The Waterline
Leaves that sit in water begin to break down quickly. As they decay, they become a breeding ground for bacteria, which travel up the stems and clog the water pathways. This results in droopy flowers and shorter vase life. Take a few minutes to remove any foliage that will sit below the waterline, and your bouquet will thank you for it.
6. Keep Flowers Away From Heat And Direct Sun
Where you place your alstroemeria matters just as much as how you water them. These blooms last longest in a cool room with plenty of indirect light. Avoid sunny windowsills, kitchens with high heat, or spaces near radiators or air vents.
Heat speeds up the ageing process of flowers, causing them to wilt quickly. You should also avoid placing them near fresh fruit, especially apples and bananas, as these release ethylene gas, which causes flowers to deteriorate faster.
7. Change The Water Regularly
Changing the water every 2 to 3 days helps keep bacteria at bay. Each time you change the water, rinse the vase thoroughly, clean the stems if needed, and re-trim the ends to help the flowers stay fresh. It might seem like extra effort, but these small actions can help your alstroemerias last nearly double the time compared to flowers left in the same water for days.
8. Remove Wilting Flowers Promptly
As the days go by, some blooms will naturally begin to fade. It's completely normal, but it's important to remove them as soon as you spot signs of ageing, browning petals, limp stems, or discolouration. Leaving them in the vase can cause the healthier blooms to deteriorate faster. Think of it as editing your bouquet to help it stay lovely for as long as possible.
9. Give Buds Time To Bloom
One of the best things about alstroemerias is that many arrive with closed buds, meaning you get to watch them open over time. Don’t be discouraged if they seem a little tight at first.
Place the bouquet in a slightly warmer part of the room (still out of direct sunlight), and the buds should begin to open within a day or two. Patience pays off; the longer it takes to bloom, the longer your flowers will last.
Where To Keep Your Flowers
Placement is key when it comes to alstroemeria cut flower care. These blooms like cool spots with indirect sunlight. Avoid placing them near heat sources like ovens, radiators, or direct sunlight, as well as near ripening fruit, which releases ethylene gas and can cause flowers to wilt faster.
Changing the water every two to three days and re-trimming the stems will also help your bouquet stay fresh for longer.
