Had a great morning with a local Girl Scout troop working on their Gardening Badge!

They toured the garden, learned the basics of designing their own, talked about reading seed packets, transplanted tomatoes to take home and did a seed germination project! They are off to a great start as gardeners!

Another fabulous Class in the Garden happened this morning! Hope you made it! And if not, join us at our next class on 6/27 when Garrett from Yakima Area Arboretum joins us to talk about great trees and woody shrubs for Yakima!

Just a note, instead of meeting in the grassy area across from our Ahtanum garden, we are now meeting in the grassy area right next to the garden, behind the arborvitae.

You still have time to come down to Ahtanum Youth Park to hear John Strong teach us how to set up our own drip irrigation. Your garden loves it more than being hit with the hose, and it is a better way to conserve water and making the most of each drop we use!

Today at 10am at Ahtanum Youth Park! Bring a chair, your coffee and your questions and join us for Classes in the Garden!

Don’t forget, tomorrow is the Drip Irrigation session of our Classes in the Garden! Join us at 10am at the Ahtanum Youth Park where MG’s own irrigation guru John Strong talks on how to get the water where your garden needs it!

Bring a chair and join us! If you’ve never been, just look for our signs in the park. If you have joined us in the past, know we are now meeting just across the road and now nexts to the garden, behind the arborvitae.

If you miss this one, you’ll be all wet. Sadly your garden will not! So come on down!

Did you attend our great class on Veggie garden issues last Saturday? MG Gini talked about cover crops.

Here is a great example of that cover cropping happening at our Heirloom Garden today!

MG Sally is cutting back the buckwheat, and laying it down as mulch around the base of the tomatoes. It had gotten taller than the new tomatoes and was shading then. So today she just did a rough chop and sprinkled the cut parts along the beds. This will help keep weeds down, keep moisture from evaporating from the soil, and eventually feed the soil. Key point is to do it before your cover crop sets seeds!

That tomato plant is hard to see, but it in there!

Great day at the Heirloom Garden this morning!

A beautiful day in the Ahtanum Youth Park Garden! The bees were buzzing, the birds were chirping, the Master Gardeners were working and the visitors were exploring! We had a great group of ladies come and tour the garden! And maybe a couple of grandbabies checking in on their MG Grandma! But we all can agree, that garden is certainly the place to be!
