When to Start Seeds in Illinois
In most cases, the all-time time to start seeds is approximately 6 weeks prior to the last frost appointment. In both Bloomingdale and Carpentersville , that lands somewhere around May 21-31 every year. This is the rule of thumb to follow when in doubt, but your seed packets should include recommendations for how early on you should start sowing!
Getting Fix
Starting seeds is biology, not rocket science! Merely a few simple, affordable items can assist you get a fantastic running first on this year'due south garden. You'll need:

Seeds need moisture and warmth to germinate properly, so your offset job will exist to create a welcoming environment for them.
Start by adding water to your tray until all of the cells comprise evenly moist, but not sopping wet, soil. Add water slowly until the soil is moist like a damp sponge—avoid turning the soil into mud!
Step two is to institute your seeds in each prison cell to the depth recommended on the seed parcel. Plant a few seeds per cell, as it'south likely that some won't germinate, and some seedlings won't grow every bit strong. Y'all can "thin out" the weaker seedlings later on.

Step iv; place the plastic encompass over your tray and leave information technology alone! At this phase, your seeds don't need light even so. However, some seeds may require a slightly warmer surround to germinate correctly. A heating mat placed beneath the tray provides the right amount of gentle, even heat. Straight sunlight is non a practiced substitute—the greenhouse effect can cause the tray to get too warm, and your seeds can get "overcooked"!
Stride five is all about waiting and watching. For the next several days, monitor the tray for changes. Keep the plastic cover on equally much every bit possible and make certain the soil stays consistently moist, simply look out for any sign of mold.

Without the actress light from the lamp, your seedlings are likely to develop problems like legginess or frail stems. Keep the grow lights on your plants for approximately 14-sixteen hours per day; using a timer will come in handy for this part. Position the grow lamp about iv inches above the soil line.
At this point, you can movement into the maintenance stage of seed starting. Check on your tray daily to manage moisture levels and look for any emerging problems. One time your seedlings have sprouted their second prepare of true leaves, use a make clean pair of scissors to snip away the weakest seedlings in every pod.
Fertilizing Seedlings
At this indicate, your seedlings are also ready for their first dose of fertilizer. Apply a high-nitrogen, water-soluble fertilizer at half strength and apply the fertilizer past pouring the water into the bottom layer of the tray. This will allow the fertilizer to gently soak in from the bottom of each jail cell, feeding your plants without the risk of fertilizer burn.
Hardening Off
When the last frost appointment arrives, your seedlings will need some time to get used to an outdoor environment. This process is known equally "hardening off."
On a nice day, bring the tray(due south) exterior and place them in a shady surface area for two hours. Practise this over again the next solar day.
On the third day, get out them outdoors in a sunny surface area for two hours. Echo this process once more the next day, increasing the time to three hours.
Continue to repeat this process daily, adding another hour each time. When your seedlings are finally spending eight hours outdoors, they're ready to move into your garden beds and outdoor pots for good!
If this is your showtime twelvemonth starting plants from seeds, you're in for a care for. While a few months seems like a long time to babysit a tray of seedlings, it's common to grow a picayune attached to your babe plants—and information technology's so rewarding to watch them grow upward!
