How to Start Phlox Seed


If your garden is in need of some colour, you may want to consider adding one of the many different types of phlox (Phlox spp.). There are two different types of Phlox species: those that grow tall and those that crawl along the ground. The species that grows to be rather tall is perfect for using as a backdrop in the garden, while the creeping version may be cultivated to create a multicoloured carpet in USDA plant hardiness zones 3 through 10, depending on the species and cultivar. Blooms in the form of stars are produced by the plants. These flowers may be a variety of colours, including white, blue, red, and purple; some species even produce bicolored flowers. Beginning your plants inside is the best option if you want to get a head start on the growing season.

You should start growing phlox from seed roughly eight weeks before the day when your region is expected to see its last frost. According to the University of Vermont, it is important to choose a plant species and cultivar that are appropriate for the hardiness zone of your garden.

Choose a suitable container to begin germinating your seeds in. Select a seed-starting tray that has drainage holes in the base of the unit. If you are going to use yoghurt cups that are empty or the bottom portion of a milk carton that is empty, you will need to manually create holes in the bottom.

Clean the container you’ll be using to grow seeds in. Combine the water and chlorine bleach that has been added at a ratio of 1 part bleach to 9 parts water. After letting the container sit in the liquid for five minutes, remove it and let it to dry in the air.

To within half an inch and a quarter of an inch of the brim of the container, add wet potting soil. Apply some little pressure with your fingertips to the soil in order to get it to seat firmly in the container.

Plant the seedlings. Spread the seeds out throughout the soil with a gap of one inch between each one. The seeds should be covered with dirt. A planting depth of 1/8 inch should be your goal.

Warm water should be used to moisten the top layer of the soil. When you are moistening the soil, use a spray bottle since this will prevent the seeds from being washed away and will keep them intact.

  1. 1. Phlox Seeds: When to Plant

    To assist the soil in holding onto its moisture, cover the container with a transparent plastic bag. Put a stopper in the bag and secure it with an elastic band. Keep the plastic roughly 1 inch above the soil surface. Put a plant name tag into the ground to assist in holding the plastic container upright.

  2. 2. Select a Seed-Starting Container

    Put the container in a cool, dark place within the home to store it. In order for phlox seeds to germinate, the temperature must be at least 65 degrees Fahrenheit. If you need more heat, you may either use a space heater or lay a seed heat pad beneath the container in which the seeds are being raised.

  3. 3. Wash and Sterilize the Container

    Attend to it until the seeds have sprouted. It might take anything from five to ten days to complete this task. Maintain a consistent check on the moisture level of the soil while the seeds are germinating. Aim to maintain a constant level of moisture in the soil.

  4. 4. Fill with Potting Mix

    Move the container to an area of the home that gets plenty of natural light. Once the seeds show signs of beginning to germinate, remove the plastic from the container. It is important to provide the seedlings with at least 12 hours of light every day, therefore place the container in a bright window. Maintain the appropriate level of moisture in the soil.

  5. 5. Plant the Seeds

    After the date when the last frost is expected in your region, transplant the seedlings into the garden. Put the phlox in spaces that are between 12 and 36 inches apart. According to the North Carolina Extension, the height of your phlox might range from three inches to five feet, and its width could be anywhere from one to three feet, depending on the species and growth behaviour.

  6. 6. Moisten the Soil

    Moisten the top layer of soil with warm water. Use a spray bottle to moisten the soil — this will keep the seeds intact and won’t rinse them away.

  7. 7. Cover With Plastic

    Cover the container with a clear plastic bag to help the soil retain moisture. Seal the bag with an elastic band. Keep the plastic approximately 1 inch above the soil surface. Stick a plant name tag in the soil to help hold the plastic up.

  8. 8. Put in a Warm Dark Location

    Place the container in a dark, warm area of the house. Phlox seeds need a temperature of 65 Fahrenheit to germinate. Use a space heater for additional heat, or place a seed heat mat under the seed-raising container.

  9. 9. Check Regularly While Germinating

    Wait for the seeds to germinate. This can take anywhere from five to 10 days. Check the soil moisture regularly throughout the germinating period. Aim to keep the soil moist at all times.

  10. 10. Move to a Bright Spot

    Relocate the container to a bright area of the house. Remove the plastic from the container once the seeds start germinating. Place the container in a sunny window to expose the seedlings to at least 12 hours of light. Continue moistening the soil as needed.

  11. 11. Plant the Phlox Outdoors

    Transplant the seedlings to the garden after the last frost date for your area. Space the phlox 12 to 36 inches apart. The North Carolina Extension says that your phlox may grow 3 inches to 5 feet tall and 1 to 3 feet wide, depending on the species and growth habit.
