Timing is essential for planting flowers, whether annuals or perennials. Planting flowers in Maine can be challenging because of the extreme climates and the poor soil structure. However, you can be a very successful flower gardener in Maine if you can properly time and plant your flowers at the right time.

The best time to plant flowers in Maine is after the last frost fall, particularly about two weeks after the last frost.

By this time, the soil is warm enough to support the germination of new flower seeds and growth of flower sets, transplants and bulbs because it will be free from the dangers of frost.

Maine spans USDA plant hardiness zones 3-6, and the last frost date is between May 21 to June 30, while the first frost date is between September 11 to October 10, all depending on the Maine planting zone you live in.

Of importance, these dates may change over the years, so you will need to be keen on the weather forecasts in your locality. There are times when the last frost will come earlier or later than the above dates.

After the last frost fall, you can start making final land preparation practices as you plan to plant flowers outside. If you have potted seedlings indoors, harden them by taking them outside for a few hours every day during the last winter days. This will help them get accustomed to outside conditions before transplanting.

Flowers that can withstand light frost effects can be planted in the first few days after the last frost fall, whereas those that are not cold tolerant should be planted after the soil warms up.

Planting flowers too late will produce short blooms or no blooms due to the extreme scorching sun. Some may wither just a few days after being planted late in spring because most young flowers do not require much sunlight.

When planted too early, they will be killed by frost or the adverse cold temperatures in the soil. Starting flower seeds indoors gives you a jump through the long growing season. You can start the seeds indoors 40 to 80 days before the forecasted last frost fall date.
