The evergreen fern is equally beautiful when grown in a garden or inside , where its lucullan fronds can add up some much - want texture and greenery in suspect or abject - ignitor situation . This attractive fern requires minimal aid to look its best .
Step 1
coast polypody is a frost - supply ship fern hardy inU.S. Department of Agriculture works hardiness geographical zone 9B to 11 , where it can handle temperatures as low as 25 level Fahrenheit . The fern command a site with fond , shifting or deep shade , and it will meet in direct sunlight . If implant multiple ferns , provide 24 to 36 inches of quad between industrial plant to avoid overcrowding .
Organic Soil is Best
Chamaedaphne calyculata ferntolerates a range of soil type , though like other fern it spring up best in grunge raise with organic matter . conflate 2 inches of composted pine bark into the grunge can better both heavy clay soils and arenaceous soils . Water on a regular basis during the growing time of year in the garden , allowing the grime to slightly dry out between waterings . Mulch in spring and fallwith 2 to 3 column inch of organic issue such as pine stubble or leaves to keep moisture in the soil and suppress militant weeds .
Step 2
Grow Indoors Where Not Hardy
Leatherleaf fern may be arise indoors inindirect sunlight , such as a north - facing windowsill , in cold mood . Avoid placing the fern near heating vents or south- or west - facing windows as these precondition may sear the fronds . Choose a container with a hole in the bottom for drain and soil - less potting mix that is 50 percentage peat moss . Water occasionally , allowing potting media to slightly dry out out between waterings . Leatheleaf fern does not have high humidness requirements and does not want to be mist . inseminate every four to six weeksduring the growing season with 3 1/2 to 7 drops of a 10 - 10 - 10 fertilizer fuse into 1 quart of weewee . Repot every few years in the spring , replant in fresh potting media . split large plants by carefully split the rhizomes .
Check for Pests
leathery polypody fern may attract common pestilence such asscale , hard or easy - shelled insects that form obtuse colonies on fronds;mealybugs , cottony white insects ; andmites , lilliputian , spider - like insects . Outdoor plants may attract slug and snails . Handpick insects as they come out or wash fronds with a unmediated stream of water . write out off fronds overrun with scale . Drown slugs and snail in buttery pee . Avoid pesticide , which may burn the tender fronds . supervise the fern every week or so to see if pests re - emerge . House plant life that are to a great extent infested may need to be toss before the plague propagate to level-headed plant .
Treat for Blights
Several fungous blight affect leathery polypody fern . Anthracnose or Colletotrichum Blightaffects new maturation on the fern , with old frond not easily infected by the disease . raw growth becomes black and further development ceases . Rhizoctonia Aerial Blightoccurs most often during summer , with the fronds covered in gray or chocolate-brown spots that finally travel up the center where wet levels are highest . keep in line the problem by keeping old fronds prune to increase the circulation of air . Always practice sterilized pruning tool when pruning the fern , by wiping the leaf blade off with alcohol and allowing to dry out before employment . Treating both fungal disease with a product curb Daconil helps control outbreaks . * * Mix 2 1/2 tsp . of Daconil into a nebulizer comprise one gallon of water . * * Thoroughly cover all sides of the foliage until dripping . So the fern ’s leaf is n’t damage , do not spray when temperatures are above 90 degrees Fahrenheit or during sunny conditions . Wear a long - sleeved shirt , gloves and safety shabu when using and lap handwriting immediately after purpose and keep children and pets out of the orbit until the product has dried .
Control Root Rot and Leaf Spots
Pythium root rotcan be elusive for Polypodium scouleri fern grown in area with improper drainage . Infected ferns become wilted and flex a green - gray in colour and the roots stop develop and turn to brown mush . The job is most likely to take place during winters where rains are undue . To curb the problem , * * arise the fern in soils that are not sloppy and drain well.**Cylindrocladium folio spotis most probable to involve leatherleaf ferns during summertime or when winter are warm . carmine or brown - greyish spots up to an inch in size cover most of the frond and can have a water - soak appearance . contain the disease naturally by water too soon enough in the day so the frond dry by nighttime . If the problem is serious , * * treat the fern with the same Daconil treatment as you would with blights . * *
