Zinnia Indoor Seed Starting Cut Flower Guide


Zinnias are beautiful cut flowers that are perfect for beginner gardeners. Here are simple steps for sowing zinnia seeds indoors.

Choose a Clean Plant Container With Drainage Holes.  If you’re reusing old plastic containers or trays, wash them thoroughly.


Fill Containers with Moistened Seed Starter Mix Tap firmly against the table or shelf to ensure the soil settles and prevent air pockets in the containers.


Label the  container with the name of the variety of plants and the date planted.


Sow two seeds per container or cell by creating a 1-half-inch hole into the soil in 2 opposite corners. You can use a pencil, dibbler, or even your finger to make a hole.


Bottom Water Your Seed Containers Set the container in a drainage tray with an inch of water in the bottom if needed. Do not  let the container sit in the water for more than an hour.


Place the container on a heated mat or in a warm corner of your house, and cover it with a clear plastic dome. This will help speed up the seed-starting germination process.


Keep your seed starts in a light and bright space, such as a greenhouse or sunroom. If you don’t have that option, keep the seedlings under a grow light.
