While these plants can grow in many different climates, their growth rate is typically higher in warmer weather than in cold weather; a minimum of 6 hours of sunlight per day is also needed to maintain these plants.
Adding fertilizer high in phosphorus and potassium can help increase this plant’s health by giving it more nutrients it needs to thrive and produce more blooms, which attract butterflies and other insects for pollination. Let’s look at growing the Butterfly Bush in Georgia.
When To Plant The Butterfly Bush Georgia
In Georgia, you can plant them from mid-February until April 1st, depending on rainfall and temperature. You can dig a hole twice as deep as the bush’s root ball and about two feet wide with well-drained soil at the bottom.
Plant your butterfly bush (with a shovel, not your hands), burying half of the roots in a trench that is just big enough to hold it upright without falling over or getting too close to any nearby tree trunks or roots.
That will ensure that the plant remains healthy and upright. Then gently fill in the hole, tamping with your hands. Water generously and continue to do so at least once a week during the first month after planting.
Conditions For Planting The Butterfly Bush in Georgia
Temperature
To keep the Butterfly Bush plant healthy and beautiful, it must be kept in a warm, shady area. The optimal temperature range for the plants is between 20 and 30 degrees Fahrenheit. That range is suitable for all bloom periods of this plant’s different colors.
Generally, the cooler temperatures are not ideal for growing these plants while fully growing. The flowering period of the pink butterflies bush will occur in late spring or early summer when daytime temperature ranges between 60 and 70 F, with nighttime temperatures not exceeding 50 F.
All other colors generally flower in late summer or early fall at daytime air temperatures above 75 F but do not require direct sunlight to bloom. Soil temperature is also essential to get these plants to bloom, as there must be a soil temperature range of between 50 to 75 degrees F.
USDA climatic zone
The best USDA climatic zone for planting the Butterfly Bush plant in Zone 8. In this USDA zone, there is a growing season of 210 days. That means the temperature stays at or below 60 degrees Fahrenheit and fluctuates by less than 20 degrees during the year.
The overall precipitation level in this USDA zone is 50 to 100 inches per year. These plants need long, hot summers with little rain and an average annual temperature ranging between 32-104 degrees Fahrenheit without any frost.
Soil
The Butterfly Bush plant thrives in soil that holds moisture. Gardeners may want to water their bush regularly for the first season or two, about once every week. After this time, the butterfly bush should only need water when it is dry, and the leaves start to turn brown; during this time, watering once every two weeks should be sufficient.
It is also vital that gardeners do not overwater their bush as this can cause growing roots and make the plant susceptible to disease. Many gardeners in areas with very little rainfall need to water their bushes daily, while others with more rainfall will only need to water their bushes when the soil begins to dry out.
These plants will still require some moisture in the winter, but it is best to water them sparingly or only when dehydrated, although there should be no prolonged periods of not watering.
When planting a Butterfly Bush plant, the soil pH should be at least six on the pH scale, which translates roughly to alkaline or basic. If the soil pH is 6, then plant it in acid soil.
If your soil is considered neutral, you should consider adding a bit of lime to the soil. This change is because the Butterfly Bush plants will not thrive if they are planted in acidic soil or if they are planted in slightly alkaline soil.
What makes the leaves turn yellow?
As the leaves on this plant begin to die, they will turn yellow and fall off. That is not a sign of disease, and new growth will soon appear. When pruning these bushes, it is important to prune them correctly. Over time, the Butterfly Bush can become a tangled mess and make it difficult for the butterfly bees to pollinate, so careful pruning is needed for good pollination to occur.
It is best to check to see if the blooms are being pollinated, as this will tell gardeners how well their plants are growing and whether or not they need to over-fertilize them.
In addition, gardeners should not over-fertilize their plants as this can cause damage and other problems with the plant’s health. Butterfly bushes that are over-fertilized may produce seed pods, which will have a minimal chance of producing butterflies.
As with all gardening projects, proper care is needed for the Butterfly Bush plant to flourish. These plants can provide years of enjoyment and beauty in the landscape with proper care. Gardeners must take great care of these plants, as any neglect can ruin the beauty of a plant and upset the balance of nature.
Butterlfy Bush Georgia: Final thoughts
The Butterfly Bush, also known as Buddleia davidii, is a gorgeous flowering shrub that requires light, well-draining soils and a sunny location. The plant survives in the USDA climate zone of 8-9.
For best performance, it needs full sun exposure and temperatures above 10 degrees Celsius(50 degrees Fahrenheit) annually. It does not tolerate frost or snow well; therefore, winter temperatures must be mild for the plant to survive long-term.
