How to start seeds indoors, step-by-step
Where to buy
My favorite seed starting supplies
Step 1: Gather your seeds and supplies.
If you ’ve alreadymade your recycled newspaper bay window , you ’re all set . If you ’ll be using other seed starting flock or cell trays , make trusted they ’re clean.(1 )
you could alsorepurpose household items into semen starting containers , like egg cartons , Dixie cups , and yogurt cups . Just lap them out and poke a few drainage holes in the bottom with a nail or an awl .
Step 2: Fill your pots or trays with seed starting mix.
Dump your seed start out mix into a large tubful or bucket , pour in a generous amount of water , and stir it up with your hands or a trowel .
As the seed commence commixture start to absorb the moisture , bestow more water as needed . ( This will take several minutes , as peat - found seed start out mixes are dull to absorb . ) You want the mixture to be uniformly dampish , like cockeyed gumption .
Fill your pots or trays with this pre - moistened come take up mix.(2 )
Step 3: Sow your seeds.
localize two to four seeds ( per pot ) on the control surface of the seed commence mixture , and gently press the seeds down with your fingers so they ’re nestled in nicely .
If your seminal fluid are very small , like St. Basil the Great or leaf mustard , you’re able to leave them uncovered.(3 )
If your ejaculate are larger , like beans or pea , or they require dark to shoot , breed them with a thin bed of seed starting mix ( orvermiculite , which also helps retain moisture ) equal to their pinnacle , ordinarily 1/4 inch to 1/2 inch .

Step 4: Label your newly planted seeds.
judge each kitty . Trust me , you will never remember what you plant where , as most seedling search the same at birth .
At this early stage , cheap plastic flora markers work great and stay out of the room , so redeem your big and beautiful metal plant markers for the garden .
Step 5: Keep your seeds moist and warm.
haze over your seeds with water.(4 )
get together your pots in a propagation tray ( orrepurpose a disposable aluminum roasting panor baking pan ) and cover with a humidness dome ( or just patently one-time plastic wrap).(5 )
If your domed stadium has vents , keep them open to help with air circulation during the sprouting menses .
Now , you necessitate to add hotness . Since sunlight is not indispensable at this detail , your seminal fluid trays can be grade wherever it ’s warm in your home , such as an attic , bathroom , laundry elbow room , or kitchen.(6 )
If your seedling plenty stay report in a warm nook , the low humidity will keep your seeds happy until they sprout . high-pitched humidness will make them sad . Only spritz the seed with more pee if the mix feels dry to the touch.(7 )
Within a couple of day to a couple of weeks , the seeds will germinate . As your seedling start to go forth , some of them will look like they ’re wearing little seed lid . ( No penury to do anything , as they ’ll fall off on their own . )
Germination ( the process of a seed sprouting)is highly variable , so do n’t stress if it feels like it ’s guide forever to materialise . In most cases , seeds will germinate within three weeks ( after that , try out starting a new round of semen ) .
Step 6: Give your new seedlings light.
At this level , the fresh germinated seedling need Inner Light . take the humidity dome or plastic wrapper , and move the seedling to the sunniest spot in your house ( preferably a Confederacy - facing window ) .
persist in to keep the mixing moist , but not overly lactating . Seedlings should be watered once a solar day or every other day , depending on how much sun and heat they get . Remember that seedling roots are fairly airless to the surface and they ’re growing in a small amount of medium , so they do n’t need a bass soak the way great plants do .
I wish using spray bottles or spurt bottle , as the gentle stream of water wo n’t give the sack seeds or impairment seedlings .
Step 7: Moving day! Transplant the strongest seedlings when they’re ready.
After your seedlings develop their first “ on-key circle ” of leaves , they are ready to be transplanted.(8 )
If more than one semen sprouted ( or if yousowed a multigerm cum like chard or beets ) , choose the strongest one and pinch or snip off the others . you’re able to even keep all of them , but be heedful part the roots if the seedlings are stuffy together .
transfer the seedling into a larger container occupy with potting mix . Hold it by the cotyledons ( the first leaves that appeared ) and try not to manhandle the tiny roots .
At this stage , you’re able to lightly douse the potting mix using a diluted resolution of liquid fertiliser or compost Camellia sinensis . Keep it round-eyed , keep it organic , and do n’t haunt too much over the nutrients.(9 )
Give the seedling plenty of sunlight each Clarence Day ( at least 12 and up to 16 hours is optimum for most vegetable seedling ) to keep the stem from getting too marvellous and spindly . ( Learn how to fix leggy seedlingsif this is happening to you.)(10 )
Step 8: Harden off those seedlings.
To get your seedling prepped for a good life outside , you canstart to harden off the seedlinggradually(11)by move it outside under diffused light for a few hours and bringing it back inside each night .
Over the next calendar week , move it from soft sun to partial sun to full sun , and for long periods of clock time , until it ’s lastly observe outside all night .
Step 9: Transplant your seedlings outdoors.
After the hardening off period , you may transfer your seedling to its last destination , whether straight into your garden or into a larger container .
And then , in a couple of months , you could bask the fruits ( and veggies ) of your task !
Footnotes
( 1)This seems obvious , but laziness have the best of us . clean-living pots are key and helpkeep tone down off at bay(an untreatable fungal disease that causes seedling to suddenly careen over and die at the soil line ) .
Discard or thoroughly launder any pots that previously house pathological plants . Avoid using leftover soil from the nursery container you brought home , as it might harbour weed seeds and bad bacterium . If you have a hefty garden , you canskip washing your potsand simply dump out the dirt from your pots before using again .
I ’ve put countless seed trays and humidness domes to the test over the years , and found thesetraysanddomesto be the thickest and strongest on the mart — they do n’t bend , flex , or crack as easily as other trade name , and can be recycle for many seasons.back
( 2)It ’s prosperous to start with pre - moistened admixture , as peat - base admixture are harder to wet down uniformly if they dry out out in pots . Although peat has a very in high spirits pee - halt mental ability once it ’s soused , it actually repels water when it ’s dry . Go figure .
If you ’re starting lots of seeds , it may be more economical tomake your own seed starting mix(that ’s my topnotch light formula for one ) versus purchase a bagged mix . If you choose a ready - made mix , here ’s a reputable brandthat I like . If you ’re looking in a local garden heart , youdo notneed anything fancy;seeds just need a basic mix of perlite , vermiculite , and peat moss ( or coco coir ) to sprout and grow into healthy seedlings . The cotyledons offer all the nutrients they need for the first week of life.back
( 3)For sure sort of plant , such as lettuce or Chamaemelum nobilis , luminance may be necessary for germination ( the process of a industrial plant sprouting from a seed).back
( 4)The moisture will help the seeds shed their protective finish and finally sprout.back
( 5)This create a greenhouse core to keep your seeds moist and warm , the keystone to germination . Most annual vegetables pullulate best in temperature of 75 ° F to 90 ° atomic number 9 . A few ( particularly cool - time of year crops ) will germinate at lower temperature .
seeded player will usually sprout in less than idealistic temperature , but the germination period will be longer.back
( 6)I like to put my source tray next to my heat vent on the floor . Some horticulture guides suggest placing your tray on top of a icebox , but most widget these Clarence Day are Department of Energy - effective and do not give off much heat.back
( 7)Toomuch piss can make the come rot . If your makeshift greenhouse is seem a bit too wet inside , remove the binding or plastic wrapper for a few hour during the warmest part of the twenty-four hour period to allow air circulation.back
( 8)The true leaf are in reality the second set of farewell that come along ; the first leaves that initially unfurl are not leave-taking at all , but cotyledon . These leaf - life structures are part of the embryo of the semen , and supply food to the seedling until its truthful leaves start the process of photosynthesis.back
( 9)I like to use aliquid seaweed / fish blending , liquid seaweed , orhome - brewed compost tea . No fertilizer is o.k. , too , especially if you start with good filth that has lot of constitutional thing added . I have grow sizable veg with no plant food through a whole time of year , and could barely keep up with the harvests.back
( 10)Insufficient light makes your seedling spindly and sapless as it channels its muscularity into produce taller and taller , straining for sunlight . To reduce this problem , I like to gently play my hands across the top of my seedling to imitate a piece of cake ; this slows down initial growth and strengthen the shank . A few brushes a daytime is all it needs.back
( 11)Hardening off is the operation of bit by bit acclimatise the seedling to its succeeding environment outdoors … getting it acquaint with the breeze , the birds , and the bees.back
