Why You Shouldn’t Plant Flowers Too Early in Spring.
Spring is a wonderful time to enjoy the beauty and fragrance of flowers in your garden. But before you rush to plant your favorite blooms, you should know that timing is everything. Planting flowers too early in spring can expose them to the risk of frost damage, which can ruin your hard work and waste your money.
What is Frost and How Does it Affect Flowers?
Frost is the formation of ice crystals on the surface of plants when the air temperature drops below freezing. Frost can damage flowers by causing cell rupture, dehydration, and tissue death. Some symptoms of frost damage are wilting, browning, blackening, or collapsing of leaves, stems, buds, or flowers.
Some flowers are more susceptible to frost damage than others. Generally, flowers that are native to warmer climates or have tender tissues are more vulnerable. These include annuals such as impatiens, marigolds, zinnias, begonias, geraniums, and petunias; and perennials such as dahlias, cannas, gladiolus, and hostas. On the other hand, flowers that are native to cooler climates or have hardy tissues are more tolerant. These include annuals such as pansies, snapdragons, violas, and calendulas; and perennials such as daffodils, tulips, crocuses, and hellebores.
When is the Best Time to Plant Flowers in Spring?
The best time to plant flowers in spring depends on your local climate and the type of flowers you want to grow. A good way to determine the optimal planting time is to use your area’s average last frost date as a guide. The last frost date is traditionally the date when the threat of a hard frost has passed. However, nature is unpredictable and frosts can happen after that date. You can find your last frost date and your hardiness zone by visiting the USDA website.
As a general rule of thumb, you can plant hardy flowers four to six weeks before your average last frost date. These are plants that can tolerate a heavy frost, lows around 28 degrees Fahrenheit. Some examples are peas, radishes, turnips, cabbages, kale, spinach, collards, broccoli, cauliflower, Brussel sprouts, and beets to name a few.
You can plant semi-hardy flowers two to four weeks before your average last frost date. These are plants that can tolerate a light frost, lows around 32 degrees Fahrenheit. Some examples are lettuce, carrots, Swiss chard, leeks, parsley, celery, cilantro, and potatoes.
You can plant tender flowers on or after your average last frost date. These are plants that cannot tolerate any frost at all. Some examples are tomatoes, peppers, eggplants, cucumbers, squash, melons, basil, and most annual flowers.
You can plant very tender flowers one to two weeks after your average last frost date. These are plants that need warm soil and air temperatures to thrive. Some examples are okra, sweet potatoes, corn, beans, and some tropical plants.
How to Protect Your Flowers from Frost Damage?
If you have already planted some flowers too early in spring or if you expect a late frost in your area, there are some steps you can take to protect your plants from frost damage.
* Water your plants well before a frosty night. Moist soil retains more heat than dry soil and can help prevent rapid temperature fluctuations.
* Cover your plants with an old bedsheet, newspaper, cardboard box, plastic sheeting, or plant cone in the evening before the temperature drops. Make sure the cover reaches the ground and does not touch the foliage. Remove the cover in the morning when the sun comes up.
* Move your potted plants indoors or under a sheltered area such as a porch or garage. Make sure they get enough light and ventilation during the day.
* Apply a layer of mulch around the base of your plants to insulate the soil and keep the roots warm. You can use organic materials such as straw, leaves, pine needles, or bark chips. Avoid using materials that can compact or retain too much moisture, such as grass clippings or sawdust.
* Prune off any damaged parts of your plants as soon as possible to prevent further injury and disease. Cut back to healthy tissue and dispose of the pruned material. Do not fertilize or stimulate new growth until the danger of frost has passed.
Conclusion
Planting flowers too early in spring can be tempting, but it can also be risky. Frost can damage or kill your plants and ruin your gardening efforts. To avoid this, you should follow the recommended planting times for your area and the type of flowers you want to grow. You should also monitor the weather forecast and take precautions to protect your plants from frost damage if needed. By doing so, you can enjoy a beautiful and healthy flower garden throughout the spring and summer seasons.
