    Step by Step Sunflower Transplanting Guide

    Our garden experts put together an 6 step guide with a few tips and tricks to make transplanting your sunflowers a success. Our guide will help you pick the right time of year, remove the plants then replant them without hurting the plant.

    Step 1: Dig Circle Around Stalk

    Start by digging a circle around each plant. Dig deep enough that you can reach under the root ball and scoop it out.

    Step 2: Remove Seedlings from Pot

    If you started the growing season early using an indoor planter you can loosen the sunflowers from the side by getting the soil wet and gently scooping it from the pot. Don’t let the plant get too tall or it won’t be able to be replanted outside.

    Step 3: Dig New Holes

    Find a new home for the flowers and dig a hole 10 inches deep. If you are moving multiple plants dig each hole at least 12 inches apart so the flowers have room to grow.

    Step 4: Prepare the Flowerbed

    Find a new home for the flowers and dig a hole 10 inches deep. If you are moving multiple plants dig each hole at least 12 inches apart so the flowers have room to grow.

    Step 5: Place Flowers

    Place each sunflower into the holes and cover with dirt until it is level with the ground. If the plants are large you may need to set up supports so it does not fall over when the wind blows. It is also a good idea to cover the soil with a layer of mulch to prevent soil run off when it rains

    The best area to replant sunflowers is in an area with direct sunlight that gets plenty of water.

    Step 6: Water the Garden

    After all the sunflowers have been replanted water the garden enough to make the soil damp. Make sure not to over water or you could wash away valuable soil or introduce root rot to the plants.

    When to Transplant Sunflowers

    The best time of year to transplant sunflowers is when the weather is warm outside and the plants are about 6″ tall. If you started growing indoors in a pot you can replant at the start of the summer.

    Transplanting Sunflowers from Pots

    Many gardeners start their sunflowers using a seed tray indoors to start the seedlings then later transplant them outside for the tallest sunflowers. Transplanting a sunflower from a pot will work most of the time – just make sure the soil is rich with compost and regularly watered.
