April - GMG Garden

4/2/25: This blog post will get updated throughout the month. Keep checking back!

Week 1: Preparations for Planting & Weeds

📅 Wednesday, April 2 at 5:30 PM
We’re doing a great job with weeding. And now we have the torch!

  • Torch the area for the extended potato row

    • Get a handle on the white-top weeds

  • Adding more city compost to the potato rows

  • Broadcasting cover crop that complements what we decided for the warm season rows - click the maps above for specifics

    • We can also do some more direct-seeding of cold-tolerant crops and flowers that can take a little cold!

  • Starting the trellising

  • Garden Prep at Home: Hardening off seedlings that are ready to go from our winter sowing! Specifically cold-tolerant plants including leafy greens

Thursday 3:45 - 5 PM: Mary K will be there with One Stone students to start on their row and get some help putting the drip line back in the larger area of the garden.

Week 2: Starting Potatoes!

📅 Sunday, April 6 at 11:30 AM

  • Bring all potato starts to the garden!

  • Laying down cardboard: Use non-glossy mostly unprinted (or one color matte), ideally staple- and tape-free cardboard to cover the entire area (two layers if possible).

    • Large cardboard can be sourced from Bob’s Bicycle on Fairview, or from furniture places. We want large thick stuff to avoid ANY gaps. Ideally double thick.

      • Smaller cardboard boxes = weeds.

  • Planting & Mulching:

    • Spread city compost and/or woodchips in 2 ft parallel strips, with 1 ft between them.

    • Place seed potatoes 1 ft apart on the cardboard, using your foot (heel to toe) to measure.

      • We’ll use pavers to mark where we can maintain the rows from.

    • Cover each spud with 2-3 quarts of compost (start with 2, add 1 later in the season).

    • Mulch rows with wheat straw to retain moisture and keep soil temperature below 80°F.

    • Wet everything down to prevent it from blowing away.

  • Maintaining the Crop:

    • A moderate amount of hilling the potatoes will be needed through the season using soil, straw, or woodchips to protect from sun exposure.

      • Just covering any spuds that breach the surface to keep them from turning green.

    • Use fresh compost to manage pill bugs and apply diatomaceous earth (DE) for pest prevention.


Tuesday 10:30 am : One Stone students are going to start planting out their row. We’ll also wrap up the relocating of the Native Plants.

  • After that’s done, Kayla offered to make a call to the city to request Compost for that area.

  • If we don’t get all the plants relocated with the students help, I’ll ask Co-op Gardeners to help.


📅 Wednesday, April 9 at 5:30 PM

  • Trellising continues

  • Transplant hardened-off cold-tolerant crops

  • Continue direct seeding cold-tolerant crops and flowers


Thursday 3:45 - 5 pm & Tuesday 10:30 am One Stone Students: Whatever we don’t finish with the trellising we can probably do with One Stone students who want to know more about garden set up.


Week 3: Drip Lines & Dump Truck Fun

📅 Sunday, April 13th at 11:30 AM

  • Drip line extension: We will work on adding more drip irrigation to increase our growing capacity as needed.

  • Sometime this week we’ll be working with a dump truck Shawna and Greg have access to in order to get our massive weed pile and other random weed-waste piles up to Diamond Street. And return with wood chips.


Week 4 & 5: Weeding, Trellising, Direct Seeding

The following applies from now through Sunday May 4th.

📅 Sunday, April 20th at 11:30 AM

  • Woodchips on cardboard in the walkways!

  • Weeding the Fairmont row

    • If we want to help out the One Stone crew, we can weed their rows too, to prepare them for planting. I’ve made some suggestions on the planting guide.

  • Getting our Trellises in order

    • With the help of a post driver, getting metal stakes on either side of each Hugel Row

      • Relocating the great pole structure from Michael and Shawna’s rows to the double tomato row. 3-4 people needed. Kayla’s got the vision.

On going through May 4th

  • Doing the rest of our cold-tolerant direct seeding around the planting chart. Updated 4/20 (top of page). A print out will also be at the garden.

  • Hardening off/preparing our winter sown seedlings.

    • Waiting to transplant tender, warm season varieties until May 10th

    • Potting up those that are getting too crowded - they’ll need to be covered at night or brought into a garage. If they’ve been winter sown, and outside all winter, bringing them inside a house could be too warm.

    • Please read this blog post for more detail on preparing seedlings.

Happening at the garden:

Friday 25th 2:30 pm: Fairmont Students plant their row out!

Friday 18th 2:30 pm: Fairmont Students clean their row! - Had a scheduling miscommunication. I’d like to help them by weeding this for them.
