Starting Seeds Indoors

Do you want a cure for late-winter cabin fever? Want a whole yard full of flowers without the cost? Want to pick and choose which flowers you have this year? Want to try some unusual or hard to find varieties? Want to get a jump start on spring? Then why not start some of those seeds indoors? It’s fascinating, it’s fun! And a great project to work on with the kids.

Most flowers...99 percent of them...are easy to grow from seed.  Just give them enough light and elbow room, and don’t let them dry out during germination. Seed starting takes little effort. Some plants have particular requirements, but the basics never change.

What you will need:

  • Seeds
  • Seed Starting Tray, Preferably One With A Plastic Lid
  • Good Quality Seed Starting Mix
  • Cookie Sheet or Something For The Trays To Sit On When Watered
  • Wood, Metal or Plastic Plant Labels. One For Each Tray.
  • Small Pots For Transplanting Your Seedlings.
  • Good Quality Potting Mix.

Lets Get Started:

1. For best germination, seeds need a loose, disease-free starting mix, not rich, heavy garden soil. Use a special, soil-less mixture prepared for starting seeds. Most soil-less seed starting mixes are so light they tend to blow around in the slightest breeze; to prevent this, wet the mixture thoroughly before you begin. Place it in a bucket, add warm water, and mix with your hands or a long handled trowel until it is evenly moist but not dripping wet. (You should not be able to squeeze any water out of a handful of soil.)

2. Fill your clean container with the damp mix. Press the seed mix down as you fill the tray, then tamp it to level and firm the soil surface, using a piece of scrap wood (a paint stirrer works well also). Add more mix to fill the container to within a half-inch of the rim. Water again before sowing the seeds so they won’t be washed around by a stream of water applied after sowing. Any excess water will run out of the drainage holes.

3. Sprinkle the seeds into the flat. Cut open one end of the seed packet and sow the seeds thinly, either “broadcast” or in row. We recommend rows; there is much better germination and the plants are less likely to need thinning (an extra step). Sowing seeds too thickly is a common mistake; seeds should be at least an eighth-inch apart. Don’t cover the seeds too deeply. As a rule of thumb cover seeds to a depth three times their diameter, or roughly a quarter inch; large seeds like peas and beans need to be about an inch deep. Use your plant labels and write the name of the plant and the sowing date; stick it into or onto the container. Trust us...you can forget what is growing in your seed flats! And...it’s amazing how many seedlings actually look alike!

4. Seeds need warmth and constant, even moisture to germinate well. This is why we suggested you purchase a seed starting tray with a plastic lid. If you don’t have a plastic lid, use a sheet of glass, acrylic or plastic wrap to cover your tray. Don’t seal it so tightly you cut off all air circulation, or mold may develop on the surface of the soil. Good air circulation discourages damping-off and other fungal diseases. If the seeds need dark to germinate, cover the flat with a black plastic. If they need light set the flat in full light-not in direct sun-which would be too hot-until the seeds sprout. Keep the soil moist. If it becomes dry to the touch, mist it immediately or set the container in a pan of warm water. Keep the seed flat warm, but not hot. Room temperature is okay. You may also want to consider purchasing a seedling mat. These are like little heating pads that keep your seedlings at just the right temperatures. As soon as the seeds sprout remove the cover and set them on a windowsill or where they can get good light. At least 12 hours of light every day is recommended. A fluorescent light with an automatic timer is ideal.

5. Like all young sprouts, seedlings need tender care until they put down good roots and get settled. Coddle them with warmth, plenty of light and water, and good air circulation. When the seedlings have developed their first pair of true leaves (they’ll still be less than 2 inches high) transplant them to a roomier container. We prefer using small individual pots filled with a professional potting mix. Begin by lifting a bunch of seedlings out of the moist soil and separating them, gently, one by one. Hold them by the seed leaves, never by the stems. Their stems will be very soft and tender at this point. Using a pencil (yes, a pencil) make a hole (deep enough to hold the roots) in the soil and tuck the small seedling into it so that its leaves are slightly above the surface. Gently tamp into place. Water using mister with a fine spray.

6. Transplanted seedlings may wilt a little, but don’t be alarmed. They will perk up after a good watering from below (set the container in a bowl of tepid water and let it drain). Keep the seedlings out of direct sun for a few days. After they have become established, fertilize weekly until they are planted outside. When the seedlings are six to eight inches tall, pinch out the growing tip to encourage bushy growth. Then, continue to pinch off the branch tips to promote compactness. As soon as the soil has warmed, move the seedlings into place into your garden. Don’t rush it. It can be a tough transition from a warm house to cold nights in the garden. To toughen up, or “harden off,” your seedlings, move them outside on warm, sunny days and bring them back in at night.

Try some unusual seeds for that “new look” in your neighborhood. Get the kids involved (what a great project when you’re stuck inside) and you all will discover a great family pastime. And... the enjoyment of telling everyone the whole family grew them from seed.    Good Luck!

 

Easy - To - Start... Flowers and Veggies From Seed

Basil (Ocimum basilicum) Basil is one of the easiest and most rewarding herbs to grow. Give seeds a well-drained mix and darkness to germinate, which takes only about 10 days. Seedlings need lots of light.

Tomatoes (Lycopersicon esculentum) Start seed indoors six to eight weeks before you want to transplant seedlings outdoors. Keep in mind tomatoes germinate very slowly in cool soil. Harden off seedlings gradually.

Zinnia (Zinnia) Zinnia seeds germinate in about seven days after sowing. Sow them thinly to avoid leggy plants.

Marigolds (Tagetes) Start seed about four weeks before you want to plant outdoors. Seeds take about 7-10 days to germinate. Transplant seedlings into loose soil at about 1-2 inches.

Morning Glory (Ipomoea) Morning glory seeds have a hard coat. To aid germination, soak seed overnight in warm water. Sow seed in individual pots, so roots won’t be disturbed when transplanting outdoors. They should germinate in 14-21 days.

Shasta daisy (Leucanthenum x superbum) The shasta daisy will germinate in about 14-21 days. Seeds need light to germinate; leave seed exposed.

Purple coneflower (Echinacea purpurea) Seeds take about 10-15 days to germinate. Give them warmth and good light.

 

 

 There are many other plants that are easily grown from seed...we just wanted to name a few.
