Have you tried starting some seeds, but your still staring at a pile of soil weeks later?
Here are some of the most common reasons your seeds aren’t germinating.
Not Enough Light
Starting seeds early in the season can be a tricky but rewarding endeavour.
One of the many issues that can arise is a lack of light getting to your seeds.
Many seeds need a lot of light to germinate.
This is where grow lights can be helpful and “trick” the seeds into thinking the days are longer, that spring has arrived, and that they should start sprouting.
Again many seeds need a certain amount of heat before they germinate.
This is true of more exotic plants like chillis used to warm growing conditions.
That is why many growers use a heat mat to help get their seeds started.
A heat mat provides gentle but constant heat and is placed under seed trays to warm the soil up.
Not Enough Water
Seeds need water to kick start a lot of the processes that begin germination.
If they arent getting enough water, then germination won’t happen.
Ensure you check on your seeds every few days, and the water is moist.
Please don’t overdo it, though, as you don’t want your seeds sitting in water, as this can cause issues of its own.
As seeds get older, they cease to be viable and won’t germinate no matter what you do.
If you are sowing from an old packet and nothing seems to be happening, this is likely the cause.
Check the packet to see if it has a use-by date, and always try to use your oldest seeds first.
Many seeds will be viable for at least two years, some even longer.
Natural Poor Germination
Some seeds just have poor germination rates no matter what you do.
Different plants have different methods for seed germination, and this results in some being excellent germination while other are poor.
Thats just the way it is.
Seed companies will often include the expected germination rate on the packet, so look out for that.
