School Garden Week of March 27th, 2023.

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!


CCS GTS Teachers!   Keep your eyes open on your email for an email from Lauren Preston to pick your times for end of the season focus group times. If you have not done the February survey, please fill that out this week as the last day is Friday March 31st.


Let’s check out the forecast.  It looks pretty good.

Best day to transplant is Thursday, you could harden off seedlings this week for a few hours a day on Monday, Tuesday, and Wednesday.


Outside in the raised beds:

It looks like we have a good window of opportunity to plant outside in the raised beds.  I would do my planting any day from Wednesday to Friday this week.  If you have leftover seeds from fall here is what you can plant:  radishes, peas, cilantro, lettuce, kale, and bok choy.   Any cool season vegetable can be planted now.  If you have some seeds in your classroom of other varieties let me know and I am happy to provide any recommendations or guidance. 

Please Note:  Plant your peas in the middle of the raised bed as they will get the tallest. Meaning down the middle in the tallest part of the raised bed.

If you have transplants in the raised bed growing right now, I recommend that you fertilize them every two weeks by mixing the pink Miracle Gro fertilizer in your watering can when you water.  If you need seeds or fertilizer contact Katie and she can check to see what she has.

Keep using your row cover,  we have cold overnight and while the spring plantings are cold tolerant,  they will appreciate a little extra protection.


Important to Note! This week and next are really the last opportunity to plant seeds outdoors in the raised beds with enough time to get a harvest so make sure you get any seeds in the ground that you need to plant!


We are pretty much done with the need to use plastic but do not throw it away.  Let it dry out and then fold it up and store it so that you can use it next year.

Inside in the Aerogarden:

Tomatoes are growing in the Aerogarden.   Follow the instructions for tomato planting carefully.  Make sure you are checking water levels and fertilize as needed.  Make sure you check water levels each Friday before you leave school so that the water level does not drop too low over the weekend.  CLICK HERE for the Aerogarden planting guide.

Keep your lights about 1-2″ from the leaves to avoid leggy plants.  Remember If you started two plants in your Aerogardens, you might need to thin to only one plant or they will overwhelm the Aerogarden eventually. You will need to start pollinating your tomato flowers once they appear.  Check the Aerogarden site for guidance on pollinating.  You will also need to do some pruning of your tomato plants to keep them growing correctly.

All of that is detailed very well in the Aerogarden Tomato Guide  –> tomato_planting_guide

Start to plan what you will do with your Aerogarden if you are leaving town for Spring Break.  Take the unit home, find a babysitter, or perhaps a fellow teacher who can keep the water added and the tomatoes fertilized. 

Want to share a kid-safe video with your kiddos on what hydroponics looks like growing in a greenhouse?  Check out this Extension Today segment we filmed last year at Howlett Greenhouse on OSU’s main campus.

Inside under LED lights.  

How do your plants look under the LED lights?   Make sure you continue to fertilize every two weeks as they grow.  The bigger they get the more you will have to water.

Make sure that you fertilize your outside plants every two weeks mixed in water according to the label.  Contact Katie if you need more fertilizer.  It is the pink crystal one for indoor seed starting and watering plants outside,  not the Aerogarden fertilizer. If you have some Shake and Feed from prior years that would be a good choice.

This week in transplanting:

  • Monday: A good day to harden off transplants for a few hours,  bring back in to your classroom overnight.
  • Tuesday:  A good day to harden off transplants for a few hours,  bring back in to your classroom overnight.
  • Wednesday: A good day to harden off seedlings for a few hours.  A good day to plant under row cover if this is your only option to plant.
  • Thursday and Friday: Good planting dates.  The predicted rain on Friday will be helpful to new transplants.
  • Be sure to re-cover your beds after you transplant.
  • Use only row cover and not the extra plastic layer so that the plants get watered when it rains.

  1. Our broccoli is several inches tall and starting to get florets. Can I transplant it under the row cover now? Thank you for your help.
