Gunnera tinctoria, or “Giant Rhubarb” is a non-native invasive plant that was introduced to Hebridean gardens in the 1980’s. Since then it has spread rapidly in the wild and is now threatening our crofts, gardens and native habitats.Click to see full answer. Also asked, how big do Gunnera grow?Sometimes called Dinosaur Food (Gunnera manicata), the Gunnera’s deeply-lobed leaves can get up to 4 feet across and the plant can stand up to 8 feet tall.Beside above, how do I get rid of gunnera? Pull out seedlings (all year round). Dig out individual plants or small patches (all year round). Cut and paint (spring): cut off the leaves and paint the stalk stumps with picloram gel or glyphosate (250ml/L) Spray (full leaf and actively growing): glyphosate (10ml/L knapsack) In this regard, how do you transplant gunnera? it’s not a good time to move it, but if your really really have to, then water it well, dig around a BIG root ball and keep it moist until you can replant it, then replant in good soil and keep moist. Idea is that most of the roots don’t get any disturbance & don’t know they are being moved.How do you divide gunnera plants?Divide the gunnera rhizomes after the plant finishes blooming in June. Push a garden fork or dirt shovel into the soil 1 to 2 inches away from the rhizomes. Lift the rhizomes with the tip of the shovel or fork tines.
