Lobelia Growing Tips
|
|
|
- Plant in a moist soil that is well-drained and high in organic matter.
- An ideal pH range of 5.5 - 6.5 is recommended for optimum performance.
- Great for bog gardens and pond sides.
- Build tussocks in bog gardens in order to keep plants out of the water. In nature
cardinal flowers grow on stream banks, in old logs, wet bottoms, and on mossy stream
bank shelves.
- Do not grow the Lobelia siphilitica or the Great Blue Lobelia in bog like conditions as it
is prone to root rot in overly moist soils.
