Starting Veggie & Perennial Seeds Indoors

Starting Seeds Indoors

Hello Fellow Readers,

Ready to dig in? A rule of thumb is 8 weeks before the last frost date (normally May 19th here) is the time to start seeds indoors. I don’t know about you, but I am counting on normal despite our crazy winter! Hence I plan to start seeds the last week of March.

Mike from Washington is a first timer and asked for tips of how-to and what vegetables he should start with. Favorites like peppers, tomatoes, celery and less loved Brussels sprouts need a long growing season for an abundant harvest and ours is not long enough to start seeds directly in the ground.

Planting containers should be at least three inches deep. Use a good quality starting mix rather than garden soil which can compact easily. Moisten but don’t saturate the mix and fill each container to a half inch below the top. Sow individual seeds into each container according to seed pack directions; typically four times as deep as the seeds width. Cover with plastic and prick holes for ventilation all the while keeping the mix moist.

Seeds germinate sooner and produce healthier roots if kept warm making the top of your refrigerator a great spot.  Or there are electric heating mats specifically for that purpose. Once the seeds sprout remove the plastic and move them into bright light; preferably under grow lights or a fluorescent shop light suspended a few inches from the plants for 12 to 16 hours a day. Move the lights up as the plants grow. If using a sunny window rotate the plants so they are not reaching for the sun.

How about starting perennial seeds indoors, asked Dorothy of Stroudsburg? Many of the seed catalogues lure us with plants that are tough to start.  But there are easy-to-grow perennials that usually bloom in their first growing season if you provide a head start. A few I tout are: Tickseed (Coreopsis), Maiden Pinks (Dianthus), Catmint (Nepeta), Blanket flower (Gaillardia), Anise Hyssop (Agastache), Yarrow (Achillea), and Shasta daisy (Leucanthemum); all are medium to high in deer resistance.

Perennials seeds are slower to germinate than annual or vegetable seeds taking up to a month to sprout which justifies starting 2 weeks earlier.  Yippee! So dig in, think spring and save lots of dough!
