There is no benefit to a tough-love approach with seedlings when they are young. They will either instantly die or become weak and then fail to thrive. Even the most stalwart plants, when young, need a considerable amount of coddling and attention.

Seeds are finicky when it comes to how deep they are planted. Some seeds need complete darkness to germinate and others require light to germinate. Proper planting depth is usually provided on the seed packet. If there is no information on the packet, the rule of thumb is to plant seeds two to three times as deep as they are wide. Determining depth can be a challenge, but if you are not sure, err on the shallow side.
Moving Seedlings Outdoors Too Soon
Suspend the lights from chains so that you can raise the lights higher as the seedlings grow. Keep the lights as close to the seedlings as possible without touching them (2 to 3 inches). When seedlings first appear, keep the lights turned on for 12 to 16 hours per day. To reduce your hands-on time, use a timer to turn the lights on and off automatically.

To be able to identify seedlings as they grow and to know when they will be ready for transplanting, you should label the seed containers as you are sowing. For every type of seed sown, use popsicle sticks or plastic plant markers and permanent ink pens to record the plant name and date sown. Insert the plant labels into the soil near the edge of the container or tray.

3. Plant at the proper depth.
You’ll find the proper planting depth on the seed packet. The general rule of thumb is to cover seeds with soil equal to three times their thickness – but be sure to read the seed packet planting instructions carefully. Some seeds, including certain lettuces and snapdragons, need light to germinate and should rest on the soil surface but still be in good contact with moist soil. Gentle tamping after sowing will help. After planting your seeds, use a spray bottle to wet the soil again.
Here are the basics in 10 steps.
Maybe you want grow plants from seeds to save money. It’s definitely cheaper than buying transplants. It will also be easier to find seeds of varieties not typically available for sale as transplants. Whatever the reason, starting plants from seeds is probably not a hard as you think. And growing plants all the way from seed to maturity is one of gardening’s most rewarding endeavors.
5. Maintain consistent moisture.
Prior to germination, cover your container to help trap moisture inside. Seed-starting kits typically come with a plastic cover. You can also use a plastic bag, but it should be supported so it doesn’t lay flat on the soil. Remove covers as soon as seeds sprout. Once seedlings are growing, reduce watering so soil partially drys, but don’t let them wilt.
Seed-starting containers should be clean, measure at least 2-3 inches deep and have drainage holes. They can be plastic pots, cell packs, peat pots, plastic flats, yogurt cups, even eggshells. As long as they are clean (soak in a 9 parts water to one part household bleach for 10 minutes), the options are endless. You can also buy seed-starting kits, but don’t invest a lot of money until you’re sure you’ll be starting seeds every year. If you start seeds in very small containers or plastic flats, you’ll need to transplant seedlings into slightly larger pots once they have their first set of true leaves. Keep in mind that flats and pots take up room, so make sure you have enough sunny space for all the seedlings you start.
You will need a container that is two to three inches deep and features holes at the bottom, for drainage purposes. The width of the container can vary – it all depends on how many seeds you wish to plant. However, remember to ensure you leave enough room for the seeds to germinate. You can buy trays from your local garden centre or online, or you can even use an egg carton. Now that you have your container ready, you will need to line your seeds with your growing medium. Do not fill your container right to the top with this combination, instead leave approximately half an inch at the top. Lightly wet with water to provide a good environment for the seeds to grow in. However, do note that soil-less mixture contains zero nutritional value so it may be a good idea to use seed and cutting compost.
There are so many benefits to growing from seed that you may choose to start planting and growing flowers and vegetables at home rather than buying them fully grown in store.
2) Learn About Your Seeds
A seed is defined in the dictionary as being ‘the unit of reproduction of a flowering plant, capable of developing into another such plant. We recently spoke about how plant cells grow and how to sow seeds indoors , so we thought we would expand on that a little bit.
Some seeds may require soaking before you plant them, whereas others do not. Make sure to check all the information on the packet as previously mentioned. If your seeds do require soaking, you will need to do so for several hours before adding to your growing medium.
Now, that you’ve got your seeds ready – you will need to plant them. It is possible to plant seeds both straight away directly in your garden soil or alternatively in containers that can then be transported outside further down the line. This decision depends hugely on the species you wish to plant as some require more sensitive care than others. To do so, you will need to know the ideal growing conditions for your plant; the germination time, and also the earliest time from which you can transport your plant outside.
