When to Plant Seeds for Flowers

Starting flower seeds indoors can give you a head start to the growing season. Knowing what time to start planting flower seeds depends on the climate of where you live, and the hardiness of the flowers you want to plant. Cool season flowers are hardier to the colder temperatures you might see in the early springtime. Flowers that are tender to cold temperatures should not be grown outside until the period of time when there is morning frost, has past.


Annuals that are hardy such as bachelor button (Cenia turbinata), calendula (Calendula officinalis), wallflower (Erysimum spp.), and clarkia (Clarkia spp.) can tolerate the cooler temperature of early springtime. You are able to start growing seeds for these flowers and other cool-season plants inside during the early days of February. The seedlings should be ready to transplant outside in March, depending on your variety. Starting your year with planting seeds for cool-season flowers can give you a very colorful garden in the spring.


Warmer-season flowers including nicotiana (Nicotiana spp.), dianthus (Dianthus spp.), zinnias (Zinnia spp.), and cosmos (Cosmos spp.) can be sown indoors during the month of March. This will prepare them for a late spring and summer bloom. These types of plants cannot tolerate the cold, so they should not be transplanted outside until frosty morning and done and gone.


Seeds for cool-season flowers can be sown right into the ground during the month of April. They can handle the remaining cooler weather and have later-spring blooms. At the end of April, warmer season flowers can be seeded outside, too. You should keep in mind that direct seeding outdoors can make the maintenance more difficult, as flower seedlings compete with weed seedlings. You should clearly mark the areas where your seeds are planted and be able to know which leaves below to each kind of plant. This will greatly help you make sure you are removing the weeds and not the seedlings.

Growing Seeds

If you choose to begin seeds indoors while it is still cold outside, remember to give your plants warmth and light. You can place a heating pad beneath the seedling tray for extra warmth. Sunlight coming through a window can be adequate for warmth, fluorescent light or a grow light is pretty ideal. Not having enough light can cause your plants to have weakened stems. To be successful in your seed-starting, proper seedling care is important.

The Benefits of Hydroseeding

Hydroseeding is a cost-effective choice and allows you to have a beautiful lawn. This is the wave of the future, and gives you a healthy lawn with faster germination. It involves a process of seed and mulch that creates a slurry and is spread around the ground.

Quality of Hydroseed

Hydroseed lawns are healthier, longer lasting, and greener than hand seeded or sodded lawns. The root is established deeper in the soil and avoid shock of being in foreign soil. The seeds end up being more resistant to external problems and yield great results the first time it is installed. The soil can hold moisture better than hand seeded or sod types, and seeds can germinate way quicker. Hydroseeding includes far less weed seeds and no layering of the soil. You can also customize the application process of different seeds.

Coverage of Hydroseed

Hydroseeding gives a thicker and more uniform lawn. It consists of a mat of interlocking fibers and creates a mat of interlocking fibers. By creating an evenly covered area, it forms a barrier to keep the seed stabilized and retains moisture and fertilizer. This results in a full and lush lawn. Hydroseeding can cover cover large and inaccessible areas such as slopes. These are usually to hard to sod. Increased plant survival also comes with hydroseeding, so it is great for big spaces like golf courses or roadside erosion control.

Water Retention

Hydroseeding can retain up to 10 times its weight in water, therefore being the best method for fast and healthy germination, as well as high plant survival. No other grass growing method has advantages of hydroseeding when it comes to water retention. Within the mix, fiber mulch and tackifiers are used to hold the mixture and seal in moisture. The water is slowly released to the roots and replenishes until the next time it rains.


Hydroseeding is typically 50-80% less than the price of sod with saving in material costs and installation prices. An average hand-sewn lawn takes about half of a day to install, but hydroseeding can be done within an hour to an hour and a half. While maintaining an even healthier lawn with beautiful results, hydroseeding is the most cost effective choice for your yard.


Hydroseeding is becoming increasingly popular for many different uses. Hillside stabilization, residential lawns, erosion control, wildfire repair, vegetation restoration, roadsides, soil renovations, national parks, city parks, and more. The varieties of seeds in the hydroseeding mix are unique and are different per job site. One main differentiation between hydroseeding and other methods of seeding is the ability to seed large areas economically.
