Antibiotics work in one of two ways: A bactericidal antibiotic kills the bacteria. Penicillin is a bactericidal. A bactericidal usually either interferes with the formation â¦ of the bacterium's cell wall or its cell contents. A bacteriostatic stops bacteria from multiplying.
Sunflowers are perfect for Florida. You'll plant seeds in the summer for fall bloom. You need to look at the seed packet and just back out the number of days to maturity as it depends on the cultivar (type of sunflower) that you choose. Autumn Beauty takes 95 to 100 days.
Temperature. Sunflowers germinate best at a soil temperature of 70 to 85 degrees Fahrenheit. Outdoor planting time is typically several weeks after the last spring frost when the soil has warmed thoroughly.unflower seeds are planted one-half inch deep. Because sunflowers are an oil-rich seed, they require slightly more water for germination than many other seeds. This requires watering the ground thoroughly outdoors after planting and not allowing the soil to dry out completely until germination occurs.
