It’s a few weeks before spring, and gardeners everywhere are starting baby plants from seed. Germinating seeds isn’t usually a difficult process, and for most veggies, the process is quite simple.

For complete instructions for starting seeds, get the seed starting guide.

But what do you do if your seeds don’t germinate?

When seeds don’t sprout, you should always take time to evaluate what happened. So I thought it would be helpful to talk about the most common reasons you might have seed germination problems.

Some years our germination is a little patchy, and occasionally whole rows of seedlings will not germinate. It is important to keep up with our germination rate to evaluate our technique and seed health.

For us, a minimum acceptable germination rate is when at least 80% of our seeds sprout. But ideally, 100% of our seeds come up, so anything less than 80 or even 90% germination rate, and we start looking at what went wrong.

Learn the 5 fatal mistakes for germinating seeds

When vegetable seeds are not germinating, there are a few common problems that you should look for.

1. You used old seeds

The first thing to consider is whether the seeds were viable in the first place. If your seeds have not sprouted within the appropriate number days (this will depend on your seeds), then you may want to consider using a pen or pencil to gently dig around in your soil and find the seed.

  • If you don’t find the seed, think back. Did youforget to put the seeds into the mix? Don’t laugh! It could happen!
  • If you find the seed, take a good look at it. You may see that it looks just the way it did when you put it in the soil. In this case, the cause for a low germination rate might be that it was an old seed or not properly stored.

If you have some old seeds and are unsure of whether your seeds were viable, you can always sprout a couple of them in a wet paper towel to check prior to planting.

For new seeds or seeds you saved last year:

  • When you saved seed, did you put them away without letting them dry completely? This can cause seeds to rot or mold.
  • Were they exposed to extreme temperatures during storage? For example, if you left seed packs in your car over the summer. High temperatures over 90 can kill the plant inside the seed.
  • Was the parent plant healthy? Seeds can harbor infection from the parent plant that may prevent sprouting, however, this is not usually the case.

2. You didn’t use new or sterilized containers

Disease issues can be a factor in seed germination. Think back to last year and whether you had any disease issues with your seedlings.

  • Most plastic containers can be reused for several years, but they need to be sanitized.

We clean ours by submersing them in bleach water at the beginning of the season.

If you are looking for a bleach alternative, try the environmentally friendly bleach alternatives that use hydrogen peroxide as their active ingredient.

Fungal and mold infections are the most common infection from dirty containers. If infection occurs you will notice a fuzzy growth on the top of the planting medium.

  • You may also see that a seed sprouts, but then rots at its base and falls over.

This is called damping off and is caused by a funal infection in your soil. A hydrogen peroxide or colloidal silver solution can help treat fungal disease on your tender plants.

3. Your technique is not right

  • If you started seeds in any mix that includes non-sterilized soil from the yard, your seeds may have been affected by disease organisms in the soil.

In order to use garden soil for starting seeds, you should sift it carefully to remove sticks and clumps. Then bake it on a cookie sheet in the oven at 180 degrees for 30 minutes. That should kill most weeds and pathogens.

You’re better off using a seed starting mix. Seed starting mix is usually a soiless mixture that has a finer grain and is free of clumps, sticks, and pathogens.

  • Did you plant your seeds too deep?

Planting your seeds too deep can cause problems with sprouting. You should also avoid pressing down on top of your seeds after you plant them. If the soil in your container is too compacted, the seeds cannot sprout or form healthy roots.

4. You didn’t provide the correct temperature

The temperature of your soil is of utmost importance in getting a good seed germination.

  • Temperatures that are too high or too low can cause problems germinating seeds.

Given all else is equal, even tray germination requires even temperatures. If temperatures plunge at night, or peak over 100 for a prolonged period, seeds will either remain dormant or die.

  • Did you leave the heat mat too high or too low?

Even when using seed starting heat mats, accidents happen. If you forget to put the temperature probe into the seed tray, the heat mat can overheat and cook the seeds.

Sometimes heat mats get accidentally turn off, or you forget to plug it in.

An alternative to the heat mat is to put them in a sunny south facing window or on top of the refrigerator. You can also use grow lights to provide heat above, and I have even seen people use rope lights to generate warmth.

5. You watered incorrectly

Seeds need to be moderately moist to sprout.

  • Seed germination is highly dependent on watering. Too dry and they won’t get the message to sprout, too wet and they will rot in the dirt.

Very young seedlings are even more tender. Seedlings do best in what we call the “Goldilocks zone.” You know Goldilocks. She likes her porridge not too hot and not too cold, but juuust right.

  • Tender seedling babies can’t tolerate drying out. While young, even a short dry period can mean death after the first wilt.

On the other hand, their tender roots will be the first victim of conditions being too wet. They can’t get the oxygen they need to carry about their business, and it will stunt or kill the seedling.

How Long Cannabis Seeds Germinate?

If you’re one of those people that have to have control over everything you might find yourself wondering how long cannabis seeds germinate. The long and short of it is that it usually takes 24 to 48 hours for the cannabis seeds to germinate. If they are placed somewhere moist, warm and dark, like a cupboard or in a propagator. These are ideal places for the Cannabis seeds to germinate and they will crack out of their protective shells.

So now you know how long cannabis seeds germinate, what will happen after?

After another two days, they should have a pair of leaves then continue growing for another two weeks until they begin the vegetation period. If you are concerned that the seed cover is still on the leaf or concerned about how long the cannabis seed germination will still take, just remember the more warmth and moisture (not dampness) will accelerate the process for the Cannabis seeds to germinate and within 24 to 48 hours it should be completely out of its shell.

HOW LONG DOES IT TaKE SEEDS TO SPROUT

12-24 hours to crack if the seeds are fresh but can take up to 2 – 3 weeks for older seeds.

if they are in soil then it deppends how deep they are?? give them 7 days im sure they will break through the soil in that time.

yea your being a little impatient. When u germinate seeds in a paper towel it usually take 1-4 days for the seed to crack, and another 1-2 days before u see any decent taproots, then u plant them and another1-3 days they will pop from the soil. You just don’t see the work going on beneathe the surface. Keep it watered. Give it about a week. If ya don’t see anything in a week, week in a half, then ya have something to be worried about.
Until then. your gonna need time and patience, expecially if your working outdoors. You got til September-October buddy.

The paper towel baggie method takes me 2 days to see a tap root.

Ph’ed water all over a paper towel placed in a baggie. throw the seed up in the thing and close the damp paper towel over the seed. DON’t close the bag. Place the bagggie on top of a warm place like a cable box or p.c. Place a bowl over the bag to trap heat. Over night the seed will POP. The tap root soon follows. 100% germ rate for me.

I’m not new to the board. Just a new name is all.

Watch that GT and FDD. hahaha

All i did was sit them in at cup of water and i waited to all of them stopped floating and hit the bottem. I fretilized the ground/soil 2 days before hand then i planted the seeds and watered the dirt. They’re in a place that gets good shade and very good light depending on where the sun is

Your probably not gonna get all 20 seeds growing. The seeds you wanna use are the thick, “beefy” ones. usually brown in color with “tiger stripes” on them. also most regular brown seeds pop too. But defiantly not the lil green ones. Those are immature seeds

yes the soil will be to hard. You best bet to assure outdoor growth: dig a big enough hole to fit a large pot. Dispose of the dirt u dug up and fill the hole with a top soil mix or organic mix from your local nursery or hardware store. Make sure the area you plant the seeds in is an area that has loose soil that becomes spongey when wet, holds water well, and drains well.

But then again pot will almost grow anywhere if the conditions are OK. But anything to make it more suitable for the plant, the more chance of maximum growth with maximum yield.

for me it takes approx 36 hours to properly germinate and then 24 hours to sprout and start showing some greenery

yea 36 hrs hrs and 24 sounds about right if u purchased the seeds from a vendor, but if im not mistaken he said he had bag seeds and he didnt know if they were old.

I’m on a grow process now, growing bag seed also, and it took from February 26-March 7th before i seen anything pop from the soil (after i germinated in a paper towel and buried the taproot)
I’m just stating from my experience.

the best thing would be to start them in little cups with good potting soil

Old thread but Incase of a search like me. Takes 1 day to soak. 24-36 hrs to crack. I’ll let you know on the soil pop once planted. Been 24 hrs hopping in am it will be sprouted.
