Tips for Growing Roseroot

Written by Mindy on December 15th, 2016

You may have not heard about roseroot since it is typically seen in European countries but a recent study of this plant showed that it could be a plant of the future.  It has been noted to grow in USDA Plant Hardiness Zones 1 through 7, which provide the cold that is required for this perennial plant.

Roseroot is propagated through plants and seeds.  Once the plants are established, they are pretty much carefree while the seeds can be a challenge to grow.  While seed propagation of roseroot can be a challenge, it is still fun to try.

roserootTo give your gardening hand an up when it comes to growing roseroot from seed, you will first need to soak the seeds in water overnight.  While the seeds are soaking, prepare your flat or pot for planting by sterilizing the container in a basin of water with a capful of bleach.  After the container has soaked for a few minutes, scrub to remove any soil and rinse in clear water.  Allow the container to dry before moving on to the next step.

Once the seeds have set in water overnight, drain them and set them aside.  Add 2 inches of sand to the container and sprinkle seeds on top of the sand.  Top the seeds with another 2 inch layer of sand and cover the container with plastic wrap.  Put the planted pot in the refrigerator for 30 days.

After the seeds have set in the refrigerator for 30 days, it is time to sterilize a seed tray. This is done as described previously.  Once that is done, mix equal parts of peat moss and sand.  Put this mixture in the seed tray.  Add water to this mixture until you see it coming out the bottom.  Allow all the excess water to drain out of the seed tray.  Next, remove the seeds from the sand and plant on top of the peat moss and sand mixture.  Cover with ½ inch of sand.

Place planted seed tray in a cool but sunny location.  Keep the planting medium evenly moist.  Germination will take about 4 weeks.

Continue to monitor the soil moisture and once the seedlings have three leaves you should transplant them into their own pots.  Place them in a location that receives indirect sunlight and care for them through their first winter.

In the following spring, harden off your roseroot to prepare them for living outside.  While your roseroot is acclimating to the outside, select its new home.  What do you need to look for?  Well, a soil that is well draining but a little rocky.  It also needs to have some protection from wind and if the area is hot, it also needs to have some shade.  Once the location has been found, dig a hole twice the width of the container and the same depth.  If drainage is questionable, place 3 inches of coarse sand in the hole.  Next, remove the plant from the container, tease the roots, place in the hole and fill in.  After all seedlings have been planted, water in the seedlings and add 1 inch of water every 10 days if it does not rain.  After the first year outside, roseroot is pretty much carefree.
