monthly meeting on Tuesday, April 9th


DATE – Tuesday, April 9th
VENUE – In-person Meeting

We are having a big orchid repotting party!

It will be a hands-on workshop and demonstration of repotting a phalaenopsis orchid. Everyone will receive an orchid ready for repotting. You will also receive expert direction from experienced growers to help with the repotting process. You will get tips to make your orchid thrive and bloom!

Sonoma County Orchid Society will supply plenty of phalaenopsis hybrid orchids. We will also supply bark, pots, tags, and gloves. (SCOS members, please bring a pair of sterilized clippers.)

We will have everything you need to get your orchid off to a great new start! Once you have repotted your new orchid, you will take it home to enjoy!

New members and guests don’t need to bring anything! SCOS Members – Don’t forget to bring your gorgeous blooming orchids for Show and Tell!

Also, please bring a snack or something to nibble on and share with the group.
