Starting a Garden From Seeds
Growing your own garden from seed can be a great activity to do for yourself or with your family. If you have never grown plants from seed let this be the year you start. You do not need a greenhouse to grow healthy transplants and many varieties can be started indoors over the next month to transplant to the garden this spring
Raising seedlings indoors will put you a few weeks ahead of the normal growing season. While the soil temperature is still a bit too cold outside for good germination of your seeds, your tender seedlings will grow happily in the warmth of a propagating light shelf. Not only will it give you a head start on the garden season, it can also save money and allow you to grow different varieties of plants that you may not be able to purchase locally.
Light shelves/growing racks can be purchased commercially (they can be pricey)
like the one on the left or you can build one yourself very economically and repurpose components as well, such as this one.
The growing rack consists of a heavy duty plastic storage shelving with recycled hanging shop fluorescent light fixtures mounted under the shelf bottoms with chains. You will want to keep the fluorescent lights about six inches above the tops of your seedlings so it is
important to be able to raise the light upward as your plants grow.
While the commercial light shelf came with specialty gro-lux bulbs, Standard fluorescent lighting is all that is needed and not a particular growing lamp light. I used one cool white light bulb and one warm light bulb. The commercial shelving came with built in removeable trays.
Consistent bottom heat is key for many types of seeds to germinate. By supplying steady warming to rootzone of your plants, a heat mat encourages successful
seedlings and cuttings. Warm season plants to start off early include eggplant, tomatoes, peppers and basil. The family will love them! You just can’t stay mad at anyone when you take a bite out of a fresh homegrown tomato still warm from the Carolina sunshine.
I have repurposed aluminum foil catering trays to hold my seed starting “flats”. My flats consist of cleaned, previously used divided plant packs, as well as cleaned empty plastic containers that held everything from cherry tomatoes, to eggs, to salad greens. It is vital that your containers have drainage holes. You need the water to get into the soil, function mechanically and chemically as needed and then drain away. Otherwise the root zone will get saturated and soggy resulting in not get enough oxygen to the plant roots and your plants will fail from root rot.
“Soil” mixtures for starting seeds comes in a variety of products. But not all seed-starting mixes and potting soils are created equally. Experienced gardeners generally have their favorites, based on what plant varieties they’re growing and the environment they are working in. Even though it’s not all that difficult to pull together, beginners may be at a loss as to what potting media to select. Extension is here to help with the trusted information you can count on.
The basic difference is soilless seed-starting mixes have a finer texture and are made from ingredients such as milled peat moss, perlite, coconut coir fiber and vermiculite. Potting soils may be used to start seeds, but they tend to be more
coarse in texture and may contain, compost or composted manure along with vermiculite, peat moss or perlite. Some seed-starting or potting mixes may contain added fertilizer as well.
As with all things, READ THE PACKAGE. Some products contain enough fertilizer to provide seedlings with sufficient nutrients to last up to three months, while others may have no added nutrients. If you are making your own mix, avoid incorporating typical garden/field soil. When potting soil ingredients include field soil, compost or manure, they may also contain some weed seeds or other hitchhikers that you don’t want to bring into your seedling’s environment.
There are several key benefits of garden-based learning for children, youth, adults, and families: Nutrition Awareness; Environmental Awareness; Learning Achievements; Life Skills; Health and Wellness; Community Building and Social Connections, and general garden-based learning. Start making memories today with starting seeds indoors. For more information on seed starting resources, contact your local Extension office or email me at email@example.com.
