Seeds vs. Seedlings: What’s the Difference?
- Seeds: These tiny powerhouses contain all the genetic material needed to grow into full-fledged plants. They’re like nature’s magic beans, waiting to sprout and flourish with the right conditions.
- Seedlings: Seedlings are young plants that have germinated from seeds and started to grow their first set of true leaves. They’re like the toddlers of the plant world, needing a little extra care and attention to thrive.
Starting from Seeds
If you’re starting from scratch with seeds, here are some simple steps to get you going:
- Select Quality Seeds: Choose high-quality seeds from reputable sources to ensure the best chance of germination and healthy growth.
- Prepare Containers: Fill clean containers with moistened potting mix, leaving some space at the top for watering.
- Plant Seeds: Follow the instructions on the seed packet for planting depth and spacing. Cover the seeds lightly with soil and gently pat them down.
- Water Gently: Water the soil gently to keep it moist but not waterlogged. A spray bottle or watering can with a fine rose attachment works well for this.
- Provide Light and Warmth: Place your seed containers in a warm, sunny location or under grow lights to encourage germination. Keep the soil consistently moist until the seeds sprout.
Using Seedlings
If you prefer to start with seedlings, you can purchase them from nurseries or garden centers. Here’s how to transplant seedlings into your containers:
- Prepare Containers: Fill your containers with potting mix, leaving some space at the top for watering.
- Make Holes: Use your finger or a small tool to make holes in the soil for the seedlings.
- Transplant Seedlings: Gently remove the seedlings from their containers, being careful not to disturb the roots too much. Place them in the prepared holes and lightly press the soil around the base of the seedlings to secure them.
- Water Thoroughly: Give your newly transplanted seedlings a good drink of water to help them settle into their new homes.
- Provide Care: Keep an eye on your seedlings and water them regularly to keep the soil evenly moist. Gradually introduce them to outdoor conditions if they’ve been growing indoors.
Tips for Success
- Label Your Containers: Keep track of what you’ve planted by labeling your containers with the name of the vegetable or herb and the date it was planted.
- Thin Seedlings: If you’ve planted multiple seeds in one container, thin out the weaker seedlings to give the stronger ones room to grow.
- Hardening Off: If you’ve started your seedlings indoors, gradually acclimate them to outdoor conditions by placing them outside for short periods each day before transplanting them permanently.
Beyond Seeds and Seedlings
But what about vegetables like potatoes, sweet potatoes, garlic, and onions? These crops don’t typically start from seeds or traditional seedlings. Instead, they use other planting materials, such as:
- Potatoes: Planting potatoes involves using “seed potatoes,” which are small potatoes or potato pieces with at least one eye (or sprout) on them. Cut larger seed potatoes into pieces, making sure each piece has at least one eye, and plant them in containers with soil.
- Sweet Potatoes: Sweet potatoes are grown from “slips,” which are shoots that sprout from sweet potato tubers. You can purchase slips or grow your own by placing sweet potato tubers in water until slips develop, then planting them in containers.
- Garlic: Garlic is typically planted using individual cloves from garlic bulbs. Separate the cloves and plant them in containers with the pointed end facing up, about an inch or two deep in the soil.
- Onions: Onions can be grown from sets (small bulbs), onion transplants, or even onion seeds. Sets and transplants are the easiest options for beginners. Plant sets or transplants in containers with soil, making sure they’re spaced appropriately.
