INKARHO Lime-tolerant Rhododendrons

The revolutionary new "Inkarho" lime tolerant rootstock is particularly recommended for growing Rhododendrons on neutral clay soils, up to pH7. This patented rootstock was developed from a Rhododendron growing in a German lime quarry, and has been the subject of an extensive 20 year breeding and testing programme. These plants are grown under licence in Germany, and enable choice hardy hybrids and yakushimanum varieties to be grafted on the rootstock and grown in a much wider range of soil types than ever before. They are hungry plants and require more feeding than other Rhododendrons to keep their foliage a healthy dark green. We recommend our own recipe Millais slow release fertilizer and plenty of good Ericaceous compost for best performance.

Please note that some of these plants are broader than they are in height, and that the specimen sizes (eg 90-100cm) are measured by the larger of the height or width.
