dahlia tuber ordering & shipping information

You will receive dahlia tubers that have been organically-grown and hand harvested from our flower farm. We do not buy tubers in bulk and resell them — all tuber stock comes from our flower farm in Lockport, NY. You are guaranteed to receive the variety you ordered. Our dahlia tubers are stored with care and are fully viable with at least 1 growing “eye” that has the potential to grow into a robust plant. Your “eye” may be invisible to you when you receive the tuber — some varieties will still be in hibernation at the time of shipping.

You will receive dahlia growing instructions, including information on planting, fertilizing, cutting, and digging/storing your tubers. This information has been specially curated by Heirloom Soul Florals. We are here to set you up for gardening success; however, we are not responsible for poor growing conditions.
