About The Pink Serissa Bonsai Tree

The serissa is a beautiful shrub that makes an excellent bonsai tree.  It has a distinct bark, small and beautiful leaves, and some of the most tiny and perfect flowers you’ve ever seen.

It showcases beautiful flowers from early spring until the fall, and sometimes all year long!

Be careful with the leaves on your serissa… if you bruise them too much, they can give off a smell.


A pink serissa makes a wonderful indoor bonsai.  It can live outside, but will die in temperatures below 50-55 degrees - so inside for a large portion of the year is best.

Make sure it gets a ton of sun (4-6 hours at the minimum) with a quality grow light, or a windowsill (south facing preferred.)

In the summer, it should be placed outside if possible - just be gentle with the temperature change.  Bring it outside for the season when the midday temperature is the same as indoors, and bring it inside for the season when temperatures are back in that range.  Generally, around 70 degrees in the mid-day.


Your pink serissa bonsai will not forgive you for skipping a watering.  Water it before the soil appears dry, and never let it dry out completely.

Depending on the soil, a few times a week should suffice when it’s indoors with decent humidity, and daily over the summer when outdoors would be fine as well.


When your pink serissa bonsai tree is indoors, using a humidity tray is recommended.


Since your pink serissa bonsai is in a small pot, and not the ground, it needs nutrients.  A slow release (pellet based) fertilizer is perfect for this, and can be added sparingly every 1-2 months during the growing season.

Pruning & Trimming

Trim back the new growth to the farthest safe point that looks good to you — but never remove all of the new growth.

A regular trim will help keep your pink serissa bonsai tree short, while helping the trunk grow thicker.


Repotting must be performed periodically on your bonsai, serissa included, when its root system has filled the pot.  If you can clearly see the roots coming out of the bottom of the pot, it’s time to repot your bonsai.

Generally, this means every 2-3 years for a deciduous tree and every 4-5 years for an evergreen.  Your pink serissa bonsai will fall somewhere in this range.

Repotting should be done in mid-summer, when the tree is at it’s least fragile state.

The serissa bonsai, along with all of its soil, should be removed from the pot.  From there, you can trim away no more than 1/3rd of the root mass (1/4th is preferred.) 

Then you can repot the tree in the same pot, or give it a newer / bigger pot to thrive in.

After repotting, your bonsai pink serissa should be thoroughly watered.

Diseases, Insects & Other Pests

Your serissa bonsai can be treated for pests like a normal serissa tree.  Just remember, your tree is miniature and will need a much smaller and more gentile dose of treatment.
