When should I transplant tomato seedlings from the seed tray? If your starting mix has some fertilizer incorporated, it will not hurt anything however, early fertilizing is not necessary. Seedlings will not need fertilizer until they have produced their second set of “true leaves”. This will allow it to warm up to room temperature, and any chemicals in the water will evaporate into the air. Let the water sit out in an open bucket or watering can for twenty-four hours before using it. Water very gently to avoid eroding the soil around the roots. Check them daily to make sure that the soil feel slightly damp.

Throughout their growth period, your tomato seedlings will need to have moist, not soggy soil. Turn it on low and place it so that it blows an indirect breeze around the area rather than having it blow directly on the plants. Good air circulation will help your tomato seedlings develop strong, stocky stems. How can I be sure that my tomato seedlings grow strong?

Excessive heat causes plants to grow leggy. This little dip in temperature overnight will encourage strong, sturdy plants. Nighttime temperatures should be between 60☏ and 65☏. Once your seedlings begin to grow, they should have daytime temperatures ranging between 60☏ and 70☏. What temperature is best for tomato seedlings? Be sure to turn the lights off after this amount of time has elapsed. If you’re growing them under artificial light, they will need between 14 and 16 hours of light daily. If your tomato seedlings are receiving natural sunlight, 6 to 8 hours a day will do. Light that is too far away will cause weak stems. Place the containers a couple of inches below the lights to encourage sturdy growth of the young seedlings. If you do not have such a location, you can use florescent light or grow lights. When they develop their first set of true leaves, you can move them into direct sunlight. When this happens, you should remove the plastic and move your seed trays and/or containers to an area that receives bright, indirect sunlight. In a few days, your tomato seedlings will begin to emerge. You may want to place your containers on top of your refrigerator to maintain a warm, consistent temperature. During the first few days of germination, your seeds will not need sunlight. You may need to add a heat source below the containers to achieve the best results. Be sure that the soil around the seeds stays a warm, consistent temperature. Place your prepared seed trays and/or containers in an area where the temperature will stay at about 70☏ consistently. What’s the best temperature for tomato seed germination? Check daily and spray the surface of the soil with water as needed. You can do this by placing entire seed trays or containers inside clear plastic bags or by simply laying plastic film lightly over the surface of the soil. Keep the soil lightly covered with plastic during the germination period. How can you keep the soil moist during germination? You want to make sure that your seeds have good soil contact on all sides. Press the seeds into the soil surface and then add a very thin layer (no more than a quarter inch thick) of light soil mix over the top. Press the medium down lightly and then simply sprinkle your tomato seeds over the surface of the soil. You should fill your seed trays or individual containers with your soaked potting medium.

How much should you water newly planted tomato seeds?īefore planting seeds, moisten your starting mix to the consistency of a well-wrung-out sponge. Stay away from heavy potting mixes because they retain too much water, encourage fungal growth and discourage high germination rates. Failing that, a very light and fluffy potting mix is a good choice. It’s best to start out with a sterile commercial seed starting medium. What is the best starting medium for tomato seeds?
