How to Start Flower Seeds


Flower seeds can be started indoors or directly in the flower bed outside. If sowing flower seeds outside, the ground must be warm for germination and free of all danger of frost. Starting flower seeds indoors allows you to get a head start on planting. It also gives the seeds an opportunity to become established plants before the birds and squirrels steal them for food. Starting seeds indoors eliminates the chances that seeds will be washed away, eaten or die from lack of moisture required for germination.

Step 1

Mix two parts potting soil, one-part compost and one-part garden soil thoroughly in a large container.

Step 2

Cut the lid off a cardboard egg carton using a kitchen knife or scissors. Fill each egg hole three-quarters full with potting mix. Don't pack as it will settle on its own.

Step 3

Moisten soil lightly with water using spray bottle.

Step 4

Place three to four flower seeds on top of the soil in each egg section. All seeds may not germinate.

Step 5

Spray the top of the seeds with water. Moisture is necessary for the seeds to sprout.

Step 6

Cover seeds with at least 1/4-inch soil mix and lightly spray the top of the soil with water.

Step 7

Place the egg carton into the resealable plastic bag and seal.

Step 8

Set the sealed bag containing the egg carton near a window where the sun can warm the contents producing condensation. This will facilitate the germination process.

Step 9

Observe daily for seedlings to emerge. When sprouts are detected, remove the egg carton from the bag and keep the soil moist until seedlings are well established.

Step 10

Thin seedlings if necessary. Seedlings will be stronger if they do not have to compete for nutrients, water or soil.

Step 11

Transplant the seedlings to a container or directly into the garden soil, once seedlings begin to grow leaves. Simply pull each egg section apart from the carton and plant directly into the soil.

Tips and Warnings

  • Once the egg carton is removed from the plastic bag, be sure to keep the young seedlings moist. This is a fragile growth phase and they will die if the developing roots dry out.
