Soaking Akita Dahlia tubers before planting is not necessary, but it can be beneficial for promoting faster growth and healthy plant development. Dahlia tubers are susceptible to disease, and soaking them in water for a few hours prior to planting can help remove any fungal spores or pathogens on their surface. Additionally, soaking the tubers can help plump them up and encourage healthy root growth.
It's important to note that dahlia tubers should not be soaked for more than a few hours, as prolonged soaking can lead to rot and death of the tubers. When soaking, make sure to use clean, room-temperature water and change it frequently to prevent the growth of any bacteria.
After soaking, it's essential to plant the tubers as soon as possible to avoid any further deterioration. Place the tubers in a well-draining soil mix and cover with a few inches of soil, water thoroughly and wait for the new growth to emerge.
