Driving in Oklahoma, seeing wildflowers on the highway is not uncommon. The variety of colors and textures makes these surfaces attractive to the eye.

Wildflowers are a great addition to any landscape and redecorating this beauty in a public garden or at home can create a delightful beauty – if the right steps are taken.

Gardeners are concerned about the environment, and in some ways wildflower gardens are more environmentally friendly than traditional gardens, said a horticulturist who uses Oklahoma State University Extension.

“Although most plants do not require human intervention in any environment, wildflowers need the right conditions to function properly. Fertilizers and other improvements may be needed when conditions are not favorable, ”said Hillock. “Once established, wildflowers must adapt well to the local climate and soil conditions.”

Indigenous wildflowers include blankets, black-eyed Susan, sunflowers, joyous weeds, purple conifers, purple primer clover, butterfly weeds, dairy weeds, blurs, golden, Mexican hats and ticks.

Late fall is ideal for planting a wildflower garden, but like any gardening, site selection is important. Consider factors such as sun and wind exposure, drainage, site topography, and site access for maintenance and irrigation. If Hillock has multiple options for a site, the desired plant species or beauty can determine the location of the wildflower garden.

It is important to clean any plants from the site and this process can take some time. Non-selective, post-emergence weeds are an effective way to kill perennial weeds and many treatments may be needed. Once invented, the area should be left untouched to see new weed growth, and then treated.

“Another option for managing plants is solarium, as long as existing plants can be managed,” he said. “Solarization is basically done using a clear plastic sheet and solar heat to cook plants and seeds. Solar heat can also be used to reduce weeds, but it does not completely eliminate weeds. Using black plastic or other obscure material blocks sunlight and stops photosynthesis, thereby killing plants.

Although not as reliable as other methods, weeding is another option. Plowing kills and helps to remove some annual weeds by stubborn root systems, but it can also help to propagate others by dividing the rhizomes and other parts of the plant that are used as propaganda for new plants. In addition, this method can also germinate seeds sown underground.

Like traditional garden beds, soil improvements are not usually necessary because the plants are generally suitable for poor soil conditions.

For gardeners who want to plant a wild flower bed, it is important for them to understand seed sleep. Many indigenous species have changed only to thrive when conditions are right after heavy rains or fires. Seeds are commonly called cold and wet periods to disrupt sleep. Seeds can be artificially broken by placing seeds in the refrigerator for four to eight weeks in a moist medium.

“Some seed companies are already selling seeds. But others do not, because untreated seeds have a longer shelf life. ” “Here in Oklahoma, it is advisable to plant your seeds in late spring to make sure the seeds are in a natural position or during another sleep breakdown process. In areas with additional snowfall, post-snow / rainfall is ideal. Another benefit is that late fall does not interfere with more spring gardening.

Successful sowing will lead to a full-fledged garden with a balance of selected species. If the space is large, divide the area into equal parts. Combine your seeds and mix well, then divide the seeds into equal parts. Next, add moisturizing materials, compost, compost, grass cover, sand or rice husk to each seed section. Add three parts filling material to each seed section to create a distribution mix. Distribute the mixture over each area to ensure good seed-soil contact without burying the seeds too deep, and destroy the seeds with feet or other tools.

Remember, wildflowers are not-and-forgotten efforts. Once the seeds are planted, pay attention to weeds in the winter. If the garden begins to grow next spring, it will need to be repaired as usual for the overall beauty and purpose of the garden.

“Wildflowers are becoming popular with gardeners who are looking to improve the ecology of cities and reduce the resources needed to beautify their gardens. This type of gardening lends itself to bringing a portion of Oklahoma’s heritage to the backyard and to show the diversity of Oklahoma plants, ”Hillock said.
