When buying plants, seeds are much cheaper than transplants. Compare two extremes. Tetraploid pelargoniums cost $2.95 for a packet of only five seeds, nearly 60¢ for each plant. A transplant, however, costs around $3. Of course, you have to factor in the cost of growing the seed, but after doing that, even expensive seed is still a bargain. Then there are the seeds you buy on sale or wholesale, or those you save from your own plants. Outside of a few pennies for seed, soil, and water, the costs are negligible for a homegrown transplant.
Tucked away in its cozy little hiding place, protected by a tough seedcoat, a baby plant waits to make its grand entrance into the world. When conditions of light, temperature, and moisture are just right, which varies by the type of seed, the embryo bursts forth. It carries just enough nutrition in the seed for the incredible feat of breaking free and stretching upward. Afterwards, it makes its own food. Through the miraculous process of photosynthesis, plant cells convert light, air, water, and soil nutrients into sugars, starches, and proteins. Seeds may be direct seeded, which means planted directly into the garden where they will grow, or started in containers for later transplanting. Most plants are better suited to one method than the other.
Direct Seeding
This is the original plan for seed-bearing plants. They flower, set seed, and some seeds manage to get a foothold. Some types of garden seeds, especially those that develop extensive root systems, are best suited to direct seeding. Direct seeding begins with preparing a seed-bed. Begin by removing all weeds and cultivating the soil. Rent a rototiller or get a good workout turning the soil by hand. Rake the soil to remove any clumps, sticks, or rocks, and break the soil into fine particles. Water the area the day before planting so the soil is moist. You may want to treat the soil with an insecticide, such as diazinon (one of the less toxic of the chemical insecticides) or diatomaceous earth (an organic alternative), especially in soil freshly turned from sod. If soil-dwelling insects such as army-worms or cutworms get your plants before they emerge, you not only waste the money, time, and effort of planting, but you fall behind in the growing season. Space seed plantings to avoid wasting seeds and having to pull out healthy plants later.
You can broadcast seeds or plant them in rows. Spice dispensers, such as those for salt substitutes, make handy, free seed broadcasters. Those with smaller holes work for small-seeded crops, such as carrots; those with larger holes, are great for bigger seeds, such as marigolds. Fill the dispenser and gently scatter the seeds evenly over the prepared area. Scatter tiny seeds more evenly by mixing with fine sand for a carrying medium. To plant in rows, use a dibble, made from a stick or your finger, to poke a hole the appropriate depth into the soil, and drop a seed or two in each hole. Use either method for raised beds or wide rows.
I include broadcast seeding because many gardeners use it, but I don't. I think it wastes seed. It is faster than placing each individual seed where it belongs. Much of the time saved is imaginary, because thinning the thickly sprouted seeds takes time. Since it is more difficult for me to justify yanking out a perfectly healthy seedling than it is to space my plantings in the first place, I take the extra few minutes spacing seeds according to their size at maturity. Since I plant wide rows in raised beds, I space the seeds a certain distance apart from a center point. For example, carrot seeds are 3 inches apart on all sides and bean seeds are 4-inches apart.
Once planted, cover seeds lightly with fine soil. The standard rule of thumb is cover seeds with soil two or three times as deep as the seed's thickness. Gently press on soil over the seeds until dirt is firm. Remember to keep moist. Tender seedlings will die if allowed to dry out.
When starting vining plants, such as pole beans, scarlet runner beans, or sweet peas, plant a support along with them. Another prime candidate for direct seeding is a lawn. Till and amend the soil; most lawns benefit from tilling in peat moss or other organic matter. Rake until as even as possible, then compact with a roller, a large metal drum you rent and fill half-full with water for weight.
Seed evenly with a spreader by walking across the area first in one direction, then perpendicular to the first pattern, and finally at a diagonal. This pattern prevents bare spots.
The best germination depends on good seed, warm temperatures, and constant moisture. Until the grass is about 1 inch tall, water it every day. Spread a grass seed mulch over the seed to reduce water loss. You will save money substantially by planting your own lawn rather than laying sod or hiring someone else to install it either way.
