9. Seed Starting Growing from seed not only gives you a much larger selection of vegetables and flowers to choose from – including unusual varieties you’re unlikely to find at a garden center – it also lets you get a jump on the growing season by starting many plants indoors. Generally speaking, annual flowers and vegetables are the easiest to grow, and their seeds germinate quickly. When to start seeds indoors is a little tricky: Check seed packets for “days to germinate” and how many weeks growth each variety of seedling needs before being transplanted to the garden, then count backwards from your area’s last frost date. (If you don’t know that date, call your extension service or ask a local nursery.) You don’t want to start too early, or your seedlings may grow weak and leggy. To get growing, you’ll need peat pots, pellets, plastic flats, egg cartons with holes poked in the bottom, or other shallow containers with good drainage; growing medium (a special soil-less mix for seeds is best); a plastic humidity cover or plastic bag; plus water, fertilizer, labels, warmth and light. If you re-use plastic pots or flats, make sure they are thoroughly clean – a couple of minutes in the microwave should sterilize them – before filling them with moistened mix to within ½-inch of top. Or use peat pellets, which expand when moistened and can be transplanted intact, without disturbing delicate roots. Whatever containers you use, place them in a waterproof tray so you can add water from the bottom, so seeds aren’t disturbed. Keep the mix damp, but not soggy.

10. Seed Starting Once seeds germinate, they need light. A sunroom or windowsill that gets lots of natural light (with daytime temperatures of 60 to 70 degrees F) might work, but most gardeners will need to put their seedlings under fluorescent or full-spectrum lights for 12 to 16 hours a day. Inexpensive “shop lights” will work fine. Position the lights immediately above the seedlings, and adjust upwards as the plants grow. When plants have two sets of true leaves, add half-strength liquid fertilizer such as fish emulsion to the watering tray once a week. Your young plants need to be hardened-off before you can transplant them into the outdoor garden. That means gradually adjusting them to the outdoors by setting them out in a sheltered, shady spot for a few hours a day. Each day, increase the time and the light exposure. Keep them watered, as small pots will dry out quickly outdoors. After a week to 10 days, plants should be ready to be transplanted into the garden – though you may still want to cover them with sheets of newspaper at night if temperatures are particularly cool. Plant seeds according to packet directions – generally, two or three times as deep as the seed’s diameter. Seeds that need light to germinate should barely be covered. Label each container with the plant name and variety, and date of sowing, then cover it with a humidity dome or place it in a plastic bag until seeds germinate – but allow for air circulation by not sealing the bag. Bottom warmth (75 to 85 degrees F) helps seeds germinate, so set trays on an electric heat mat, or atop a refrigerator or radiator.

11. Greenhouses A mini-greenhouse helps maintain warm temperatures in the soil and air, which aids in seed germination. Most mini-greenhouses have a plastic tray that holds soil or pots and clear plastic covering that allows in light. These greenhouses are usually used indoors, although you can also set them outside during sunny weather if the temperature is above freezing. The clear covering continues to allow light in after the seeds sprout, creating a greenhouse environment during the early plant growth period. The greenhouse to the left is mine, which I bought for $30 at a local discount retailer. Small walk-in greenhouses like the one to the left can be found in a current ad for $50

13. Raised Bed Gardening For space efficiency and high yields, it’s hard to beat a vegetable garden grown in raised beds. Raised beds can improve production as well as save space, time, and money. They also are the perfect solution for dealing with difficult soils such as heavy clay. In addition, raised beds improve your garden’s appearance and accessibility.vegetable gardensoilsclay One reason raised beds are so effective for increasing efficiency and yields is that crops produce better because the soil in the beds is deep, loose, and fertile. The quickest and easiest way to make a raised bed is simply to add lots of organic matter, such as well- rotted manure, compost, or shreddedleaves to your garden soil. In the process, mound up the planting beds as the organic content of the soil increases. organic mattercompostleaves My preferred method for raised bed gardening is to first remove the sod grass. Next, I line the edges with landscape timbers and add organic topsoil, composted manure and peat moss in equal parts. Some gardeners also add expanded shale (shown in my hand below), which helps keep soil aerated. We keep a large composter going all year. All garden waste from gardening, mowing and pruning as well as organic household waste is composted. Note: it is not a good idea to compost meat, dairy, or feces from carnivores. Our composter provides enough organic content to keep 2 raised beds rich in organic compost and mulch year-round.
