How long should seedlings stay in starter trays?

Typically, after sowing the seeds, the cell trays are used for around 3-4 weeks before transplanting occurs – whether it be to an outdoor plot or into a larger container.

How do you germinate seeds in trays?

Moisten the newly planted seeds with a mister or a small watering can. To speed germination, cover the pots with plastic wrap or a plastic dome that fits over the seed-starting tray. This helps keep the seeds moist before they germinate. When you see the first signs of green, remove the cover.

Should seedlings get direct sunlight?

Initially place seedlings outdoors in a sheltered spot – protected from wind and direct sun. Each day following, expose plants to another 30-60 minutes of filtered sunlight. By the end of the hardening-off time frame, seedlings should be experiencing the same amount of sunlight they’ll receive in the garden.

Should seed trays have holes?

Any type of seed tray that you use must have sufficient drainage holes and saucers. The holes keep water from getting trapped for a long period of time. The saucer underneath prevents dirty water from dripping where it shouldn’t and will also retain some of the moisture in the tray.

How many seeds do you put in a seed tray?

Plant at least 2 seeds in each hole. If both of the seeds start to grow, you can always cut back or remove the weakest looking plant. Plant 4 seeds if they are small. This gives more chances for them to grow.

Should you put seed trays in the sun?

Most seeds will not germinate without sunlight and will perform best with 12 to 16 hours each day. Indoors, place seed containers in a sunny, south-facing window and give the container a quarter turn each day to prevent the seedlings from overreaching toward the light and developing weak, elongated stems.

Do seedlings need direct sunlight?

Acclimate seedlings to direct sunlight. It is best to do this over a three-day period by placing them in direct sunlight during the morning only of the first day, then increasing their time outside by a few hours each day until they are vigorous enough to be transplanted.

Soak the seeds in water overnight. This way, the seeds get all the moisture before they hit the soil. Then you can fill the starter trays with soil. Push the seeds into the soil, maybe only ½ inch deep.

What is the first step after planting seeds?

Triggering the process of germination is the first step after planting the seeds. Many seeds will have their own set of requirements that need to be met to successfully trigger their sprouting.
