Lime resistant rhododendron
Rhododendrons are beautiful and well liked but they are very sensitive soil pH level. They prefer soil that is around pH 4,5-5,5 and are unable to grow properly if lime is present. But this is less of a problem today, as we offer varieties that are adapted to thrive in soil around pH 7.
Their flowers and leaves show great variety and can be found in every color except blue. The most common varieties are white, yellow, pink, purple and red. Dried flower have to be broken off, otherwise they won’t regrow the next year. We recommend that they are planted either between the beginning of March and the end of May or the beginning of September and the end of November.
Rhododendrons also show a great variety in size. Some species remain on the ground while others grow to up to 2-6 m tall. They don’t like an excess of sunlight and feel best in shade or partial shade, even under a larger tree, but they do need some light. Since their roots don’t go deep, the ground should be airy and capable of letting through enough water. They require a lot of water and respond strongly to drought. Species that are not resistant to lime usually require a soil transfer before planting.
