The first thing you must do when you want to start a garden from seeds is to make sure you can get all the necessary equipment or materials to do this properly. You will need pots—to start, use peat moss pots. Other pots and planters, tools, potting mix, plant markers, watering supplies, grow lights, fertilizers and sometimes heated seed germination equipment are just some examples of what you may need. You will also need some desire and patience.
You have selected the seeds of the plants you have chosen to grow. This requires a little careful research to know which ones will work where you plan to grow your garden. Be sure to read the instructions on the back of each seed packet for the zone in which you reside. And to achieve optimal results, follow the recommended timeline: for example, planting three weeks before the last frost.
Now here is an easy how-to guide to getting started: Loosen and dampen the potting mix before putting it into peat moss pots or other seed starting containers. The mix should be thoroughly moist, not dripping, however. Each peat pot can be filled with the prepared potting soil about 2/3 full. Avoid packing mix into the pots. Plant at least three seeds in each peat moss pot. Some seeds require pre-soaking or chilling before planting. The instructions on the seed packet will tell you if this is necessary. Cover the seeds with some more soil loosely and water. Markers for easy identification will be helpful to place in each pot. Using any type of plastic, cover the peat moss pots loosely. The plastic acts as a greenhouse holding in moisture and heat. When the seedlings start to emerge from the soil remove the plastic.
The ideal temperature range for seed germination is 65 to 70 degrees Fahrenheit. Seedlings need between 12 and 18 hours of light each day. A fluorescent or high intensity plant light may be necessary for this to happen. When the seedlings start to grow leaves, fertilize them. At 2 to 3 inches tall, the seedlings can be transferred into larger pots. If two or more seedlings have emerged within the same container, remove all but the strongest seedling. Remember to cut instead of pulling out unwanted seedlings as their roots could be intertwined below.
Two to three weeks must be allowed to introduce seedlings to the outdoors gradually. Move your seedlings to a shady spot for increasing amounts of time each day. Gradually increase their time outdoors, and make sure to protect them from inclement weather.
Remember to water the seedlings before and after planting. Do what makes sense here. Do not over water which will wash out the seedlings. Soil that looks muddy probably is and requires better drainage. On the other hand, soil that looks and feels dry needs watering. Seedlings will wilt and die without water. Use your judgment to provide the best environment for the seedlings to grow strong.
