Online Master Rain Gardener Certification
Welcome to class! Start your Rain Garden planning here!
Follow the syllabus below, and watching the class videos. Plan on some homework - getting outside and measuring and drawing.
There are five classes. Watch a video and do the homework. By the end you have your rain garden all planned out, and you are ready to dig.
Let me know you if you are taking the class self-paced! Then, when you are done, I can give you your certificate and Master Rain Gardener t-shirt. Just fill out this form, so I know you are taking the class.
Class discussion will be held on an online forum, with flexible hours. So even if you have a day job – you can take this class!
Feedback Forum: We will be using a forum for class discussion and feedback: either the Houzz GardenWeb, or our Facebook Group. Choose one to join, and post there to get feedback from instructors, classmates, and Master Rain Gardener alumni.
If you have questions, you can always e-mail Susan Bryan. Keep in mind that with the Washtenaw County shut down and shelter-in-place order, responses may be delayed. A quicker way to get questions answered is to ask the Master Rain Gardeners in the Facebook group.

Class 1: "What & Why" - Introduction & a Rain Garden Tour
- Get inspired! Watch a fun rain garden video.
- Start thinking where you will build your rain garden. It can be your own yard, or a willing friend’s.
- Take photos of the area (or potential areas).
- Start a new thread on the GardenWeb forum, or Facebook group, and post the photos of your site there. Explain what is going on in your site. Do you have basement flooding? Are you solving a problem of some kind? What is the source of the runoff water? (roof, driveway, patio, etc.) Do you have other needs in this space (sports, views out windows, you would like a tree, etc.)
- Read pages 3, 10-12 & 22-24 of the coursepack.
- Take Quiz #1.
CLASS 2 Video: Where to Put It and How to Size It
- If you revised your rain garden location, take another picture and post it on the GardenWeb Forum or the Facebook Group, in the thread you started.
- Do a percolation test in the spot where you are planning the rain garden. (Dig a 18” deep hole and fill it with water. Wait for it to soak in. Fill it again. Note the time it takes to soak into the ground.)
- Measure the approximate roof/ impervious-area that will feed the garden. (Coursepack p.14)
- Calculate the approximate roof area that will feed the garden (20% of the size of the roof.)
- Read pages 13 (measuring section), and 15-20 (sample designs) of the coursepack.
- Post your percolation rate and your roof area on the forum, or FB group, in the thread you started.
- Watch this video on digging a rain garden.
- Take Quiz #2:
CLASS 3: "How" - Planning and Digging
- Measure your outdoor space using the methods outlined in class and described on page 13 of the coursepack.
- Draw up a base sheet on graph paper (1 square=1 foot), mapping the house location, and any fences, trees, etc., that are relevant.
- Draw up a few tentative rain garden shapes on the base plan.
- Think of some plants that you would like to try in the rain garden. Post them on the forum or FB group, in your thread.
- Post your base sheet on the forum or FB group in your thread by Monday morning.
- Quiz #3
CLASS 4: Planting Design: The rain garden plant palette
- Draw your rain garden design on your base sheet.
- Draw the outline of the garden; the bottom; the berm; the cut edge. Make sure bottom is big enough. Does the number of squares (square feet) in the bottom correspond to the number of square feet you calculated you would need? If not, take the relatively more wet, or dry, conditions into account as you pick plants.
- Draw the water conveyance (pipe, or overland flow).
- Draw in individual, or areas for specific plants. List the plant palette you will be using.
- Post your plan, plant list and photo of site on the forum, or Facebook group, in your thread. If you draw it with pencil, just take a digital photo of it and post. Or you could use the digital drawing tool of your choice.

- We will especially focus on plant combinations and making it beautiful. So bring your suggestions! We will collaborate as a class.
GOING FORWARD: Dig and Plant your Rain Garden!
- Dig it yourself, or recruit help.
- Plant it. Frequent your local nursery. Find a local native plant nursery. Or do mail order. Divide up perennials in your garden to put in your rain garden, or ask a friend to share.
- Incorporate compost in, and mulch.
- Watch it grow! Watch it absorb water when it rains.
- Post photos of your finished garden on the forum, and bask in the compliments of your fellow MRGers.
- Send a note to Susan Bryan [email protected], so she can add your garden to her official map - and send you an official t-shirt!
- Congratulations - you are a certified Master Rain Gardener!

GIVING BACK: Become a leader and a resource for your community
- Help out newbie Master Rain Gardeners-in-training on the forum, in the Facebook group, or in your neighborhood.
- Document your rain garden in some cool way that we could share online. YouTube? Stop motion photography? Be creative!
- Share your rain garden: have a garden party where you show off your rain garden. Put your garden on a local garden tour. Invite a local garden club.
- Share with the next generation: help a scout build a rain garden as a project. Help your local elementary school put one in.
- Volunteer to maintain a public rain garden. There are many rain gardens in parks or in front of public buildings that need some love. Weed them, or better yet lead a weeding work day so others learn about their value. Contact Catie Wytychak for opportunities in Ann Arbor, Dexter, Saline, and Ypsilanti [email protected].
- Send Susan [email protected] a note about your activities so she can celebrate your success. And you might be selected for one of the Master Rain Gardener Leadership Awards!
