Frequently Asked Questions
When is my Moss Amigo order arriving?
Orders are processed within 3–5 business days. Delivery time after processing is 3–6 days for Standard Shipping and 2–3 business days for Priority Shipping. Please note that these timelines may vary during holidays or launches of limited edition items. Your patience is greatly appreciated.
How do I care for my Ball Moss Amigo? Do I need to switch the water out?
Moss Amigos are easy to take care of—whether you’ve got a green thumb or are a new plant parent! We recommend keeping your Moss Amigo out of direct sunlight and changing out its water every 2–3 weeks with filtered water.
Will my Ball Moss Amigo retain its spherical shape?
Yes, with a little love and care! Marimo moss balls are native to lakes and other cool, aquatic environments where the movement of water helps them retain their round shape. If you notice your moss ball is starting to look flat or irregular, try taking it out of its jar and gently rolling it between your hands.
How long will my Moss Ball live?
Marimo moss balls can live for decades under the right conditions! Following our simple care tips will help keep you and your moss friend happy for a very long time.
How big will my Moss Ball get?
Ball Moss Amigos are constantly growing and photosynthesizing! Marimo moss balls grow at an average rate of 5mm per year, so don’t worry, your Moss Amigo won’t outgrow its jar anytime soon!
Why is my moss ball turning brown?
Your moss ball might be getting a little too much sun! Marimo moss balls will start to brown if their environment is too warm. Try moving your moss ball to a cooler location with indirect or minimal light and changing out the water. Gently rinsing out your moss ball and adding a healthy pinch of salt to your jar can also help your Moss Amigo return to its natural green color within a week or two!
I love my tiny Moss Amigo hat! Can I keep it on 24/7?
We love that you’re having fun with our Moss Amigo accessories and letting your moss ball’s personality shine! We recommend taking the hat off after you’re done playing dress up. This will ensure your hat stays in good condition for the next time you want to show it off!

Can two moss balls co-exist or keep more than one moss ball in the same jar?
They can definitely coexist with adequate space. However, please note that we currently offer the moss ball only as part of a kit.
How long can the moss ball remain in its packaging? Should I set it up immediately?
We recommend setting it up as soon as possible. However, the moss ball can stay in the delivery bag for 3–4 weeks at room temperature. Upon arrival, please check its condition to ensure it’s in good shape.
Can I buy the Moss Ball alone?
At this time, we only offer our moss balls as part of a kit as it helps us manage our inventory efficiently and ensures the best experience for our customers. However, we’re always exploring ways to improve, and if we decide to sell moss balls individually in the future, we’ll update our website.
