Calathea rattlesnake plant shines with interest, color and texture
Lovely elongated leaves have interesting markings with a ruffled edge
Calatheas enjoy a light well draining soil
A mix of potting soil and perlite and peat
Coir will keep the roots happy if well mixed with lighter soils
They do not like to be overly root bound
If you want to encourage faster growth choose a pot about 2 inches wider in diameter than the current pot
Use a well drained ceramic or plastic pot
Calatheas enjoysindirect light for best leaf variegation and optimal growth
Shield the plant from strong direct light in summer south and west sunny windows
These plants love low mineral, soft acid water between 5.5 and 6 Ph
Hard water high in minerals and salts will burn the leaves
Calatheas are happy at 50% to 60% humidity
They can tolerate higher, do not let it drop under 40%
Optimal temperatures for Calatheas are 65 degrees F. to 75 degrees F.
Calatheas are sensitive to cold drafts from windows and doors
Calatheas require a regular fertilizing schedule but, they are susceptible to fertilizer burn
Apply a good quality fertilizer monthly through spring and summer at half dose
Sharp sterile hand pruners or sharp scissors are preferred for pruning
They will give a clean cut that will heal quickly
Pruning is usually done to shape the plant or cut off unsightly leaves
Calatheas grow wider rather than taller with time
For the best care your Calathea leaves enjoy occasional washing
Healthy leaves with a good clean surface are most able to resist pests
Neem oil leaf shine and water is a good choice for leaf washing
Calatheas are especially susceptible to spider mites
Stress by longterm poor watering practices, poor light, extreme temperatures and soil conditions are contributors to pests
Propagation is best done through root division
Gently pull apart the two rhizomes to separate them
If the roots are heavily intertwined cut them as necessary with sharp sterile scissors or small pruners
