This is a weekly look at what is happening in the school garden to assist teacher educators engage their students in agriculture. It can be used by garden students of all ages however!
Have you been using the Growing Teachers Throughout the Seasons guidebook to assist you with your growing?
Want to learn what Growing Teachers Throughout the Seasons (GTS) is? Check out the Guidebook HERE and the 20 Online Modules HERE! It is a great way for a teacher to learn how to engage their kiddos in agriculture in a data driven and teacher tested method based on the academic calendar.
If you are winding down the indoor and outdoor growing, I put the instructions for closing out the systems at the end of this post.
Lets take a look at the weather:
Outside in the raised beds:
Hopefully you have all your plantings outside in your raised beds, if you have those available to you. Only a few more days of school left this semester!
- It looks like this week has some great growing weather.
- Make sure you water before you leave for break or the weekend, especially if we do not get rain this week.
- Your plants should be fertilized according to the package directions to maintain good growth.
- This week also has great harvest days. Check out the harvest video below.
- You want to get all the produce harvested and the beds cleaned up and tarped before you leave for summer.
Here is a video that show how to safely harvest and store your fresh leafy greens
Inside under LED lights:
This month you are maintaining collard greens under LED lights for transplanting outside in the raised beds later this month or for maintaining under the lights to harvest in the classroom.
- Make sure to fertilize according to the directions with the pink fertilizer.
- Water as needed. They are growing fast!
- Make sure to check and water on Friday before you leave.
- Email questions to me at mcdermott.15@osu.edu
After you get the collard greens transplanted outside, if you have no other plants under the LED lights, make sure to clean all your pots and trays and store them with the lights, including the cord, in a safe spot for next semester.
Inside in the Aerogarden:
This month we are harvesting tomatoes from the Aerogarden.
- Make sure you are pruning as directed in the Aerogarden instructions.
- Make sure to pollinate your flowers to maximize your harvest!
- Check water levels daily! The tomatoes are growing fast and using lots of water.
- Make sure to get a harvest and then follow the cleaning instructions at the end before you leave for summer.

Keep the tomato under the lights by pruning as needed.
I need some better pics of tomatoes in Aerogarden Harvest units. Does anyone have a pic to share? Send them my way!
Aerogarden has some great information on planting on their website. CLICK HERE for their product manual website.

Here are the instructions for closing out your systems for the summer.
CCS GTS Teachers! It is time to get a last harvest and get your growing spaces cleaned and put to rest for the summer.
With only a few weeks left in the season it is time to think about harvesting and then cleaning up your indoor and outdoor spaces for the summer. I highly recommend that you do not garden during the summer in your outdoor space unless you need to do that for programming. Harvest your produce, pull any weeds, and then cover the raised bed with black plastic. That will prevent weeds and soil loss so that your outdoor agricultural space is ready to go in the fall when school starts back up. Enjoy your summer!
Closing Up Your Garden
Please be sure that all of your garden systems are closed up before you leave for the summer. We are getting closer to the last day of the year and now is a good time to engage your students to assist you with garden clean up. Here is some helpful information from Katie.
Outdoor Raised Bed:
- Harvest all of the remaining produce from the outdoor raised bed.
- Remove any weeds that are present.
- Cover with black plastic and use landscape pins to pin down the ends, middle, and sides of the plastic.
- Add some pavers or large rocks on top of the plastic to keep the wind from pulling the landscape pins out.
- If there is an issue with vandalism at your site, you may want to take your white hoops off of your bed and store them in your classroom.
- The black plastic is important because it will keep your garden free of weeds and pests over the summer. Then in August, all you will need to do is roll back the plastic, mix up your soil, and you are ready to plant. Please be sure to fold up this black plastic and store for use the following May. This item will not be replaced each year.
- Be sure to clean and fold up your fabric row covers and clips and store them for the following year. These items will not be replaced each year.
Row Cover Cleaning:
Row cover can be washed by hand in a sink or large tub of hot soapy water and then rinsed a few times in clear water. Or you can wash it in a washing machine on the gentle or delicate cycle. It’s best to dry it in the sun as it will also help disinfect it and brighten it.
Indoor Grow Stations : Cleaning your AeroGarden
Start by dismantling your garden and cleaning out your indoor plants and any leftover roots. Roots can grow into the filter, so be sure to clean it out and reinstall after you’ve finished cleaning the bowl. If the filter looks too worn, replace the filter to prolong the life of your pump. Be careful not to throw away your filter by accident! It’s easy to do when removing plant roots.
After clearing out the roots, you should clean and sanitize your AeroGarden® hydroponics growing system to help prevent the growth of root pathogens that can destroy your live plants. There are various ways to clean your garden:
If you have a dishwasher:
- Put your grow deck and bowl in the top rack of the dishwasher.
- Run through a warm or cold water cycle (do not use a hot water or heat dry cycle).
- Reassemble to start your next round of gardening.
If you don’t have a dishwasher:
- Fill the bowl with either water and a ¼ cup of chlorine bleach OR 5 cups of distilled white vinegar (no need to use water if you’re using the vinegar). Vinegar also helps prevent and clean up mineral deposits in your garden.
- Let the water pump or aerator circulate the solution for 5 minutes.
- Empty the solution, rinse well, and then fill with clear water (no bleach).
- Allow the pump or aerator to circulate the clear water for 5 minutes.
- Empty and rinse once more to ensure that all solution is rinsed from the bowl.
Cleaning the Grow Deck:
Sometimes roots will grow through the nozzles on the grow deck and prevent proper water flow. Separating and cleaning the grow deck of any stray roots can help keep the water flowing efficiently. The grow deck can be separated on almost all AeroGarden® models.
First, remove the grow deck from the bowl of your AeroGarden® and place it upside-down on a flat surface. Locate the tabs on the underside of the deck and push the tabs inward and down. The tabs are flexible and designed to be separated. Use a scrub brush or similar cleaning tool to remove the roots and any other debris from the grow deck. Snap back together in place.
For your LED light and seed starting trays:
- Clean trays and potting cups with soap and water (they are also top shelf dishwasher safe).
- Remove the sides of the LED light and place back into the box with the light panel.
- Store all of the potting cups, the timer, plug, and extension cord, trays and lights in a cabinet or storage tote. If you have any extra potting mix, fertilizer, or seeds please store them with these other supplies.
