Harden off seedlings prior to planting out by moving them outdoors into a sheltered, frost-free location at least 3 days prior to transplanting.ĭon't forget to label what you planted. Fertilizing recently planted seeds or young emerging seedlings is not recommended. Start fertilizing a few days after they have been planted out in the garden using 20-20-20 water-soluble fertilizer once or twice a week.seedlings that are too tall will tend to break and dry out more easily once planted out into the garden. The internodes (spaces between leaves along the stem) will be small. has a good root system but is not root-bound (tight, hard ball of roots) or has lots of roots growing out of the Jiffy-7.All leaves that grow after these are true leaves. They are "seed leaves" called cotyledons and are round. has no more than two sets of true leaves. The first leaves that grow are not true leaves.For more details, check out our article on growing your own seedlings.Leave a fan blowing on your young seedlings as they grow to help to grow heartier plants and to reduce some seedling diseases. Research has shown that stem diameter can be increased by providing seedlings with constant air movement from an oscillating fan – or by lightly brushing seedling tops with a tea towel or stick at least 20 times daily.Place seedlings under lights after germination, which is crucial for the growth of healthy seedlings. seedlings require a minimum of 14 hours of light each day.Soil should be moist like a damp sponge, but not soggy. Take care not to over water your seedlings.Use a heat mat if you have one, or place pots in a warm spot like the top of the fridge for germination. At 24☌, seeds will germinate in 5 or 6 days. Sow 2 seeds 1 cm deep per JIffy-7 or container and then thin to the strongest plant after they have grown their first set of true leaves.Otherwise the rim acts as a wick and will dry out your seedling.) (Both of these types of pots can be planted directly in the soil, but be sure to bury the rim of these pots. Fill them with a soil-less mix that contains peat or coir and vermiculite and/or perlite. Another way to reduce root disturbance is to use home-made newspaper pots or peat pots.Remove the plastic once seeds have germinated. Once they are planted, cover with plastic or a dome and do not water. Soak the Jiffy-7's for 20 minutes in warm water to fully hydrate and expand them. Jiffy-7's are good for sowing seeds because there is less root disturbance when planting.For example, in Wollaston Lake (northern Saskatchewan) your plant out date is June 5, so start your seedlings around the first of June for planting out around June 20. You can transplant seedlings as soon as daytime and nighttime temperatures are warm at least 18☌, about 2 weeks after your last average frost free date. Start seedlings about 2 weeks prior to transplanting out.Larger transplants will experience transplant shock when they are planted outdoors: plants will not grow for several weeks (or at all) depending on the level of transplant shock they experience. Seedlings should only be 10-14 days old before planting out (cotyledons have emerged along with only one or two true leaves). Melons do not like root disturbance from transplanting, so it's important not to start seedlings too early.Seedlings can sometimes also be purchased from a local greenhouse. If you live in the far north, you can grow melons as seedlings. Direct seeding works on the prairies, so using seedlings is not necessary. They can be seeded directly into the garden once the soil is very warm (at least 18☌, but even warmer is better), usually about 2 weeks after your plant out date. Melons are a warm season plant that need between 52 and 85 days to maturity. Landscaping at the U of S - A storied history.Weddings, photography & events on campus.
