How to Start Your Seeds Indoors

It’s that time of year when you can start planning for your planting!

Many people are beginning to plant vegetables and flowers indoors in order to transplant them outdoors when the weather is warm enough. This helps you get a head start on your spring garden. Check out the advice below to see what things you can do to start your indoor seeds.

Growing your own foods in your garden can help you become more self-sufficient - saving you money and allowing you to grow the foods that your family will need. It’s also a great way to help teach children about responsibility and work.


The date you determine to plant your seeds will vary depending on where you live. You’ll want to figure out when the last frost of the season will be. It also depends on what you’re growing. If you are planting something that grows quickly, you don’t need as much time before the final frost. If you having something that grows slowly, you’ll need lots of time. Usually the seed packs will have an indication on the label of how many weeks are required before transitioning to an outdoor setting.

Usually, you’ll want to move seedlings outdoors when it’s consistently above 50-degrees both night and day.


One of the most difficult aspects to overcome when starting seedlings indoors is light. You can start seeds in a windowsill that gets at least 8 hours or light per day. Most gardeners will need to use additional lighting or special machines to simulate the sun. Even if you use an artificial light, you may need your plants to be under the light for 12-15 hours a day.

Seed Choice

You might not be able to use any seed that you’d like. Remember that you’re going to have to transition these plants into larger pots that will end up taking more space. If the plant grows rapidly, you’ll have to have space to expand your plant area quickly. You’ll also have to be able to adapt quickly. If the plants don’t grow that well indoors, you might have to restart - be sure you can pick a plant which has inexpensive seeds.

You probably shouldn’t grow things like lettuce, spinach, cabbage, beets, onions, potatoes, or carrots indoors. They usually take up a lot of space or don’t transplant very well.


You should also consider what type of soil you’ll be using. Using potting soil to start your plants indoors might give them an initial advantage. Be careful that when you transition the plants outdoors that you’re still giving them enough nutrients that were provided with a potting soil. Since potting soil is full of things like peat, vermiculite and fluffy matter that retains water well, you’ll have to ensure that these same elements are present in the outdoor soil to the plants aren’t shocked when they’re transplanted.


After all, you’re starting your seeds indoors so they won’t die in the cold winter frosts. Seed starting starts in two stages: Germination and growing. Germination is also known as the sprouting stage - when the embryo of the plant emerges from the seed casing. You’ll need to water the sprouts during that stage, but more importantly, you’ll need to apply gentle heat to the sprouting seeds. You can place them on top of your fridge or a few inches above your radiator. There are also a number of heating mats sold for heating seedlings.

After the seedling start to grow and they’re placed in soil, you’ll need to make sure that the plant stays warm enough. Remember that your house might get cooler next to windows and at night. While you’re wrapped up in a blanket, your plants are not. Be sure to keep them at least at 50 degrees or above.


While some gardeners are accustomed to allowing their plants flourish in the rain, indoor plants won’t be able to do that. You’ll have to make sure that your plants are getting enough water. In the same stroke, you’ll want to make sure that your plants aren’t being over-watered and become too moist indoors growing mold.


The weather can be unpredictable. For that reason, it’s a good idea to slowly transition your plants to the outdoors. Set them outside for a day allowing them to grow accustomed to the outdoor weather. If the weather gets too cold, you can pull them back indoors. If the weather continues to improve, plant them in the ground.

I’ve been trying the new method of sprouting in a mason jar. It seems simple–put a teaspoon or two of alfalfa seeds, cover with an inch or two of pure water. I’ve changed the water twice a day and even after 6 days they still are not sprouting. Any idea why? Has anyone else tried this and got it to work?

You’re draining after rinsing, right? It’s not clear from what you wrote. You don’t leave them in water or they’ll end up fermenting or even rotting. See this instruction page from Cultures for Health.
