Seed Starting And What To Plant When

What To Plant When

Getting Ready To Grow
In preparation for indoor seed starting, I’ve setup my grow lights and work area, and now I’m pouring over the seed catalogues and my current seed inventory.
I’ll be ordering some new seeds as well as using up what I have on hand. The zinger with seed orders is the curse of many mail order businesses: postage costs. It’s best to place larger orders less often or combine orders with friends to keep costs down.

My main concern is that I don’t want to run out of my favourite types of peas, salad greens, and kales later on in the year, right when it’s time to plant more. To avoid this tragedy, I started a system when I plant seeds where I flag any seed packet that’s running low and it gets noted in my Order More file. This, my dear friends, is what happens when you are an avid list writer with a dash of OCD. Some neuroses do have their perks.

    I love the chart. I am in New Hampshire (region 5a/b border) and many of your plantings will work here as well. Could you either explain or point me in the right direction to learn what your rotation letter mean? Thanks so much

      Hi Marcel, I just updated the post to show the crop rotation chart. Just click on the image for a larger view.
      I change where I plant each group every year to reduce the chance of pest problems. Also, certain veggies do well when planted in soil that previously contained certain other veggies, so it incorporates that information as well.

    Hello I just got 100 cat whisker seeds off of a plant in bloom on Saturday. It had white blooms. With alot of internet research I cannot find what season to plant the seeds. If you could help me at all that would be awesome. This was a beautiful flowering plant and I do not want these seeds to go to waste. Thanks!!
