How to Care for Mimosa Flowers: A Florist’s Guide to Keeping Their Golden Beauty Alive

Mimosa (Acacia) is one of the most delicate seasonal flowers — loved for its fluffy yellow blooms, but notorious for its short vase life.

Often called the “diva” of spring flowers, mimosa dries quickly, sheds easily, and reacts fast to dry indoor air. Even in perfect conditions, mimosa typically lasts just 2 days. With attentive care, you may enjoy it for up to 5–7 days.

Here’s how florists keep mimosa looking fresh for as long as possible.

Why Mimosa Is So Fragile

Mimosa flower heads naturally hold very little moisture while having a large surface area, meaning they lose water rapidly. The stems also block easily, which prevents proper hydration.

Translation: mimosa is beautiful — but needy.

1. Hot Water Treatment (Florist Emergency Method)

If your mimosa starts wilting or shedding:

1. Recut stems by 1–2cm

2. Dip the bottom 2–3cm into hot water (60–80°C) for 10–20 seconds

3. Immediately place stems into clean, room-temperature water

This opens the vascular system, clears resin blockages, and dramatically improves water uptake.

2. Change Water Daily + Recut Stems

Every day:

• Replace with fresh water

• Recut stems at a slight angle by 0.5–1cm

Mimosa blocks extremely quickly — skip this step and dehydration follows.

3. Placement Matters: Cool, Humid, No Drafts

Keep mimosa:

• In a cool, bright room

• Away from radiators, heaters, and air conditioning

• Out of direct airflow

If your home feels dry, lightly mist the surrounding air morning and evening (never soak the blooms).

4. Light Misting (Only If Needed)

If flowers begin to lose fullness, apply a very light mist.

Important:

• Use minimal water

• Never drench flower heads

• Avoid trapped moisture (can cause mould or browning)

Bonus Tip: Mimosa Isn’t Meant to Last Forever

In France and Japan, mimosa symbolises spring — fleeting, joyful, brief.

As a cut flower, it’s admired for beauty, not longevity.

If you’d like to preserve it, mimosa dries beautifully. Its colour slowly shifts from bright yellow to soft butter tones — each stage has its own charm.

At LovFlowers, we believe in working with the rhythm of the seasons. Some flowers are here for longevity. Others are here to remind us to slow down and enjoy the moment.

Mimosa belongs to the second category.

Final Thought

Mimosa doesn’t exist to last.

It exists to remind us:

Spring is short. Beauty is now.

Enjoy it while it’s here.
