How to Start Seeds: A Step-by-Step Guide
1. Choose Your Seeds
Select seeds based on your gardening goals and the types of plants you want to grow. Mixing vegetables, flowers and herbs is a great way to enjoy each all season long. Check seed packets for specific planting instructions and timing.
2. Gather Your Supplies
You’ll need:
- Seed trays or pots: Select ideal tray size for seed sizes.
- Seed starting mix: A lightweight, sterile medium that promotes germination.
- Labels: To keep track of your varieties.
- Watering can or spray bottle: For gentle watering.
3. Prepare the Seed Trays
Fill your seed trays with the seed starting mix, do not compact soil in tray. Moisten the mix well but avoid over-saturating it.
4. Sow the Seeds
Plant seeds according to the depth recommended on the seed packet. Generally, smaller seeds are sown closer to the surface, while larger seeds are planted deeper. Gently cover the seeds if required with soil or vermiculite.
5. Water and Cover
After planting, water the trays gently to settle the soil around the seeds from the bottom or mist gently to prevent disrupting the seeds. Cover the tray with a humidity dome to maintain moisture. Remove dome daily to ensure proper moisture.
6. Provide Light and Heat
Position your seed trays in a warm location or use a heat mat to keep the soil temperature consistent. Once seedlings emerge, remove the cover and place them under grow lights or near a sunny window, ensuring they receive at least 12 hours of light.
7. Fertilizing
Once seedlings have developed their first true leaves, begin fertilizing weekly with a 5-5-5 or 10-10-10 solution.
8. Bumping Up and Transplanting
When seedlings have developed a good root system and a few sets of true leaves, they are ready to be transplanted into larger pots (bumping up) or directly into the garden. Be sure to harden them off by gradually exposing them to outdoor conditions for a week prior to planting outside.
