Seed Starting Tips Part I: Containers


Spring is here! And across the world, gardeners of every age are getting ready to plant their gardens - whether they're growing containers of herbs on the porch, a plot of vegetables, or a sunny bed of flowers.  Nurseries, garden centers and even drugstores are stocking up on potted plants and seedlings to sell, but those of us who like a little more variety, and maybe want to plant a larger garden cost-effectively, will know to pass up the potted plants and head over to the seed rack.  Buying seed to start yourself will give you far more plants for your money, as well as offer many more varieties - usually varieties of heirlooms and other neat flowers and vegetables you can't find as seedlings in pots.  Plus, starting your own seeds is always so much more rewarding!  And with a little patience and practice, it's really not difficult to get the hang of!

With that in mind, I wanted to address a series of seed starting issues, step-by-step, and pass along a few tips.

Containers for Starting Seeds

Unless you plan to sow seeds directly into the ground (a perfectly viable option), planting in containers will allow you to keep a closer eye on germination and give your seedlings a little extra protection.  Seedlings in containers can be easily moved into a protected area if there is heavy rain or an unseasonably hot day, then transplanted into the garden when they're big enough to take better care of themselves.  So, you're going to start your seeds in containers... but what type of container?  Really, mostly anything you can find that's two to four inches deep will do, as long as it's clean (so disease isn't spread to your new seedlings) and allows drainage.    

I'm a recycling, reusing, composting fanatic (not to mention avid do-it-yourself-er), so some of my favorite seed starting containers are also the simplest solutions:

  • Reused nursery flats, pots and six pack containers: Wash and disinfect with hot soapy water and rinse in a dilute solution of water and white vinegar.  (Or bleach, but bleach is pretty nasty, unnecessarily harsh stuff, both on your skin and the environment, and vinegar works fabulously as a substitute.)  Rinse and save for next year or recycle them after transplanting.
  • Paper egg cartons:  Avoid the polystyrene (Styrofoam) ones, all the time, always.  Once it's created - from chemically altered fossil fuels - the stuff sticks around forever, filling landfills and polluting ecosystems... So really, just avoid it altogether, in every form.  Besides, paper egg cartons are biodegradable, so there's no need to even transplant your seedlings.  Just pull or cut apart the individual cups and plant; the seedling with grow roots right through the carton, and will be even happier for not having had those little roots disturbed in transplanting!           
  • Yogurt cups:  Wash and punch holes in the bottoms for drainage.  Rinse off and recycle (or save for next year) after transplanting.
  • Milk or juice jugs/cartons:  Cut off the tops, punch holes in the bottoms, and plant.  Cardboard cartons can be composted after transplanting, and plastic jugs saved for reuse or recycled.
  • Cereal boxes:  Cut out one large panel (the front or back) and tape the top flaps closed.  The cardboard does start to get soggy and break down after a couple weeks, but by then the seedlings should be ready to be transplanted.  And, the best news, soggy cereal boxes can be composted when you're done with them!  Hooray!
