How To Start Plants From Seeds

Sow, Sow, Sow Your Seeds
In order for seeds to germinate successfully, they need moisture. The key to watering seeds is to provide a gentle, consistent source of moisture. Never let your seeds dry out. Use a gentle spray from a watering can to keep the soil moist. Always use room temperature water, and if your water is chlorinated, allow it to sit for 24 hours before using. Consistently warm temperatures are also essential for germination. In fact, some seeds require soil temperatures as high as 85 degrees. However, most germinate in temperatures between 70 and 85 degrees. A root zone heating mat will provide consistent bottom warmth vital for germination.

How to Sow Seeds
Moisten your geminating mix and scoop it into seed-starting flats or containers. Determine the planting depth of the seed from the instructions on the seed packet. Large seeds can be easily inserted into the soil with the finger-thumb method. Smaller seeds are hard to sow in small numbers, so mix the seeds with a little sand for bulk. You can sow them by hand or add the seed-sand mixture to a salt shaker and shake them directly onto the growing medium.

Plant more seeds than you think you need; this insures against poor germination and seedling mortality. Once your seeds are nestled into the growing medium, cover the flat with a clear plastic cover until the seeds germinate (this will help conserve moisture evaporation). Once the seeds start to sprout, take the plastic cover off immediately because the heat build-up could actually kill emerging seedlings.

Seedling Care
Once your seeds have germinated, you need to make sure they have the proper environment and nourishment to help them grow into strong plants. The following are requirements for raising top-notch seedlings:

Light
Although most seedlings don't need light to germinate, they need lots of light to grow - nearly 10 to 12 hours of sunlight a day. A south facing window may work but you are better off starting your seeds under Floralites. These special fluorescent bulbs provide the right light intensity and solar spectrum colors required for plant growth. Place the lights about 6 to 8 inches above the seedlings and continue to raise them as the plants grow.

Food and Water
Water your seedlings whenever the surface of the germinating mix feels dry to thetouch. If the soil dries out too much, the plants could die. But if you over water, youmay encourage fungal diseases. Seedlings also need to eat. Use an easy-to-apply liquid fertilizer, such as Fertilome Blooming & Rooting Plant Food every two weeks following the appearance of the seedling's first leaves. Don't fall into the more-is-better trap with fertilizing, though.

Thinning
Overcrowded seedlings will remain thin and weak. Perform seedling triage and keep the most vigorous seedlings; snip off the extras at the base with a pair of small scissors. Don't thin seedlings by pulling them up by the roots.

Transplant Time
Before you move your seedlings to their permanent place in the garden, they need to be acclimated. This process is called hardening off. To do this, place the seedlings outdoors in a well-protected spot and gradually expose them to more sunlight each day. Harden off the seedlings for about 10 days.
