How To Grow Marigolds Indoors Step By Step

In this article, I’m going to show you how to grow marigolds indoors. Let’s get started.

In pre-Hispanic Mexico, marigolds were known as the flower of the dead, and they are still utilized as a symbol during Day of the Dead celebrations!

Marigolds are common garden plants because they grow quickly and easily and come in a variety of color combinations and sizes.

Marigolds can also be grown indoors as houseplants.

Marigolds brighten up the flower yard with their orange and yellow hues. These hardy annuals are ideal for indoor gardening or kitchen windows.

Although certain types, such as the crackerjack marigold, can grow to be 4 feet tall, lesser varieties, such as the dwarf French marigold, grow to be 6 to 8 inches tall.

How To Grow Marigolds Indoors

Fill the planting cells in the seed tray with sterile planting material. For this stage of the growing process, any excellent potting soil would suffice. If you like, you could just use a flower pot or planter instead of the seed tray.

Fill the pot with potting soil to three-quarters capacity. 1/8 inch deep is the recommended planting depth for marigold seeds.

Apply a thin layer of soil to the top. The roots will not be able to build a deep root system if the seeds are planted any deeper.

If the seeds are planted too deeply, they may not germinate. Thoroughly water the seeded area. Do not soak the soil, but make sure it is sufficiently wet to feel damp.

Wrap plastic around the seed tray or pot. Placing the entire planter or pot inside a plastic food storage bag is an easy way to cover it. Using tape or rubber bands, fasten the plastic or storage bag.

Plant the seeds in a bright, southern window or beneath a grow light. Depending on the soil and weather, marigold seeds germinate in five to fourteen days. With warmer temperatures, germination occurs more quickly.

Once the seeds have produced two leaves, remove the plastic. Make sure the soil remains moist. If the soil is dry, spray with a water bottle. Watering newly planted seedlings might cause root damage.

Throughout the growing season, keep an eye on the new plants for watering and light requirements. To ensure a constant display of blossoms, deadhead the plants (remove spent blooms).
