While young, even a short dry period can mean death after the first wilt. ![]() Tender seedling babies can’t tolerate drying out.She likes her porridge not too hot and not too cold, but juuust right. Seedlings do best in what we call the “Goldilocks zone.” You know Goldilocks. Very young seedlings are even more tender. Too dry and they won’t get the message to sprout, too wet and they will rot in the dirt. Seed germination is highly dependent on watering.Seeds need to be moderately moist to sprout. You can also use grow lights to provide heat above, and I have even seen people use rope lights to generate warmth. Sometimes heat mats get accidentally turn off, or you forget to plug them in.Īn alternative to the heat mat is to put them in a sunny south facing window or on top of the refrigerator. If you forget to put the temperature probe into the seed tray, the heat mat can overheat and cook the seeds. Did you leave the heat mat too high or too low?Įven when using seed-starting heat mats, accidents happen.If temperatures plunge at night, or peak over 100 for a prolonged period, seeds will either remain dormant or die. Given all else is equal, even tray germination requires even temperatures. Temperatures that are too high or too low can cause problems with germinating seeds.The temperature of your soil is of utmost importance in getting good seed germination. You didn’t provide the correct temperature If the soil in your container is too compacted, the seeds cannot sprout or form healthy roots. You should also avoid pressing down on top of your seeds after you plant them. Planting your seeds too deep can cause problems with sprouting. Seed starting mix is usually a soiless mixture that has a finer grain and is free of clumps, sticks, and pathogens. You’re better off using a seed starting mix. That should kill most weeds and pathogens. Then bake it on a cookie sheet in the oven at 180 degrees for 30 minutes. In order to use garden soil for starting seeds, you should sift it carefully to remove sticks and clumps. 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.A hydrogen peroxide or colloidal silver solution can help treat fungal disease on your tender plants. This is called damping off and is caused by a funal infection in your soil. You may also see that a seed sprouts, but then rots at its base and falls over.If infection occurs you will notice a fuzzy growth on the top of the planting medium. If you are looking for a bleach alternative, try the environmentally friendly options that use hydrogen peroxide as their active ingredient.įungal and mold infections are the most common infection from dirty containers. We clean ours by submerging them in bleach water at the beginning of the season. Most plastic containers can be reused for several years, but they need to be sanitized.Think back to last year and whether you had any disease issues with your seedlings. You didn’t use new or sterilized containersĭisease issues can be a factor in seed germination. Was the parent plant healthy? Seeds can harbor infection from the parent plant that may prevent sprouting, however, this is not usually the case.Ģ. ![]() High temperatures over 90 can kill the plant inside the seed. Were they exposed to extreme temperatures during storage? For example, if you left seed packs in your car over the summer.When you saved seed, did you put them away without letting them dry completely? This can cause seeds to rot or mold.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.įor new seeds or seeds you saved last year: In this case, the cause for a low germination rate might be that it was an old seed or not properly stored. You may see that it looks just the way it did when you put it in the soil. If you find the seed, take a good look at it.Did you forget to put the seeds into the mix? Don’t laugh! It could happen! If you don’t find the seed, think back.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. The first thing to consider is whether the seeds were viable in the first place. When vegetable seeds are not germinating, there are a few common problems that you should look for. Learn the 5 fatal mistakes for germinating seeds 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.Įasily keep track of your germination rate with these garden worksheets. For us, a minimum acceptable germination rate is when at least 80% of our seeds sprout. ![]()
