Overwintering Petunias: Growing Petunia Indoors Over Winter
Growing petunias indoors is not only possible but it’s actually pretty easy if you follow some simple rules. You don’t need special equipment or any specialized skills. If you’re interested in growing your own indoor plants, then you’ve come to the right place!
If you have ever wanted to grow your own indoor plants, then here are some tips on how to do it.
First things first, you’ll want to get yourself a container large enough so that they won’t wilt in the cold weather. A 5 gallon bucket will work just fine for most plants. I like using these plastic buckets because they’re cheap and easy to clean up after use. They’re also reusable and make great containers for herbs or other small plants.
You’ll also want to buy a few seeds from a nursery. Most nurseries sell their seeds online, but you can also go into a garden center and ask them to order some for you. Some of the best places to look are Seed Savers and Garden Connection. These two sites both stock many different kinds of seeds at reasonable prices. You might even be able to find some free samples there too!
Once you have all your supplies, it’s time to start planting! Fill your container with soil. Make sure you don’t put too much in so that your containers don’t get top heavy and fall over.
You can also add a bottom layer of gravel or small rocks for drainage. This is especially important if you live in a climate where it rains a lot. You don’t want all that moisture just sitting in the soil and rotting your plants.
Now, you’re ready to plant! Just take your seeds, dip them in water for about a minute, and then stick them into the soil. You should plant them about as deep as they are in their shells. Try to space them out so that they have enough room to grow. Don’t plant them too close to the edges though!
You don’t want to knock them over when you water or feed them later.
Now you just have to give them some light and keep them watered! These guys can’t survive on their own, so you’ll have to take care of them. Just set the container in a sunny window (that doesn’t get a lot of direct sunlight) and add a little water once a week. You should also feed them every couple weeks too. You can use either an organic fertilizer or an organic seed starter.
You’ll know its time to transplant your petunias when you notice them starting to wilt. You can keep them in their little container, or move them into the ground. If you want to plant them in the ground, just dig a hole and gently lower them into the ground making sure the roots stay intact. You don’t want to cover them or crowd them. Just gently place them in there and keep the soil around the edges loose.
Water it well after planting.
Now you just have to keep watering and feeding them every week and watch your petunias grow! You’ll have bright, beautiful flowers in no time.
Storing seeds so you can grow more next year is easy too. Just let the petunias dry out completely (soft and brown) and place them in an envelope or container where they won’t get ruined.
These are some of the basic instructions on how to grow petunias from seed. If you want to learn more techniques, I would suggest joining a local gardening club or taking classes at a community college. The more you learn, the easier it is to grow beautiful flowers and plants.
