nasa suggest houseplants to reduce house pollution

Pollution is a well-known word to one and all and unending afflict to everybody.Actually it has many types including house pollution but we do not anticipate the severity of pollution in our home.It's creates a pack of health problems one after another,so both NASA and Associated landscape contractors of america are combined to inquest on house plants for reducing pollution in the house.They are given final report on 1989 and pronounced that certain organic compounds such as benzene,formaldehyde,ammonia,methanol and trichloroethylene create numerous health hazards to human as well as pets,so they tested almost thirty indoor plants,here I pick out a few plants from the lot,these are also do not pernicious to your pets.

What are the causing elements of house pollution?

NASA mentioned so many elements creates pollution,these are:

  • Airtight sealing of buildings:Somebody wanted to reduce energy consumption but this method completely preventing enter the fresh air,so finally negatively affecting on human health.
  • We are using various building materials at the time of house construction such as ceramics,plastic pipes,foam core,metals,bricks,concrete and more.
  • We are using different types of furniture items in our home and in office,these items made with different toxic chemicals.
  • Someone smoking cigarette in our home but smoking affects not only on their health but also health risk around them.This is almost demolish our happy home environment.
  • Dust items,repaired electronic gadgets,candles etc..
  • smoke released from burning gas and grills when you start to make food items.
  • Insanitary items
  • Floor cleaning chemicals,room sprays,perfumes,mosquito coils and liquids,doormats and more items released harmful chemicals into the air.

How house pollution affect on human health?

Actually house pollution creates adverse effect on health such as eye allergies,lack of mental agility,anxiety,skin rashes,discomfort for breathing,headaches,blood cancer,kidney problems,gastric complications,asthma and more.

List of NASA recommended house plants:

1.Rhapis excelsa:

rhapis excelsaRhapis excelsa is also called as broadleaf lady palm,it is belongs to arecaceae family.It is easily grown on every climate conditions including sub-tropical,temperate,tropical etc..and filtering harmful chemicals in your home such as formaldehyde,xylene and toluene,ammonia and also non-toxic to your dogs and cats.

How to grow Rhapis excelsa?

It is growing up to 8 to 12 feet but growth rate is low so required small to middle range size pot.
It is sustainable in different soils such as loam,peat,sand.silt etc,but remember moisture retain is very important for preventing dryness and allowing adequate water,so moist soils are appropriate.
It is well grown under the aegis of partial shade and cannot tolerate in full sun.
It's growth rate is low so no need high amount of fertilizer,you can add less amount of nutrients in case leaves turned into yellow color.
Medium level of water is required but pouring the water regularly otherwise gray spots appeared on the leaves and also leaf scorch occurred,sometimes leads to shedding of the leaf.
Rhapis excelsa is well grown at room temperature as well as lowest temperatures.
Most of the interior plants requires high humidity but this lady palm plant thrive in moderate to high range humidity.
Pest Control:
Basically lady palms are resist from pests and various diseases but some insects threaten,these are spider mites,mealybugs and scales,so if you follow efficient methods then easily get rid of above all insects.

2.Gerbera Jamesonii:

gerbera jamesonii Gerbera jamesonii also known as barberton daisy,the transvaal daisy and barbertonse madeliefie and belongs to Asteraceae family.It is a flowering plant in various colors such as red,yellow,pink or orange,so most of the people likes this quite pleasing ornamental flower plant in the world.It is completely filtering benzene,formaldehyde and trichloroethylene.

How to grow Gerbera Jamesonii?

Sun light:
It requires full sun so you must put the plant beside window.
It will efficiently grow in a 2 parts sphagnum,one part loam and one part perlite soil mixture.These combination of mixture help to the retention of adequate water and help to well root formation and also prevent soil compaction.
Medium level of regular watering and well-drained pot are needed otherwise root rot occurred and destroyed the entire plant,so my slight suggestion is 5-tier stackable porous pot,it will save your room space and pull out the water through bottom side holes.
It is well grow at temperature range between 18°c to 24°c.
It requires 30% to 50% relative humidity in your house at a present temperature.
9 to 15 cm is better,so I aforementioned the pot appropriate.
International fertilizer development center recommended 45% ammonium nitrate,35% urea and 20% water solution for providing rich nitrogen to the plant and improve cut flowering growth.
Pest control:
aphids,thrips,snails,spider mites are damage the plant growth rate and causes plant death so you can easily remove all those insects with using neem powder or Neem oil or insecticidal soap solution.

3.Kimberly Queen Fern:

Kimberly queen fern Kimberly Queen fern scientific name is Nephrolepis obliterate and belongs to Lomariopsidaceae family.It is filtering formaldehyde,xylene and toluene.

How to grow Kimberly Queen fern?

It is grown 3 feet height and spread 3 feet so required 10 inch round shape pot.
Kimberly queen fern required moist and well-drained soils,so sandy,silt and loam soils are the most preferable.
It requires bright light under the partial shade,so better to keep beside window.Remember it is intolerant direct sun exposure.
Apply 1/2 strength 20-20-20 liquid fertilizer onto the foliage of the plant twice a month.
This interior plant is very sensitive with over watering,it causes leaves turned into brown color so requires moderate level of watering when the soil become dry out.
It requires very low temperature between 60°F to 75°F.
Actually it requires low temperature so as usual need high humidity,so use humidifier for increase humidity as well as reduce ailments, if you are stay in arid climates.
Pest control:
Either low watering or over watering or insufficient nutrient plants affected by pest but this plant not like that because consumed only moderate water and do not require high amount of fertilizer,so Kimberly queen fern is the most resistant plant from pest.

What are the other initiatives taken for reducing house pollution?

There is a possibility for reducing indoor pollution when we take proper proceedings along with house plants,these are:

  1. Keep the smoking stoves outside of the house.
  2. Arranges chimney in kitchen room for pulled over the harmful gaseous molecules to the outside of the house.
  3. Built house with good ventilation for entering sufficient air and sunlight.
  4. Refine various items everyday
  5. pledge and partake of giving new hopes for future generation.So we have to plant trees in open spaces for our own boundless benefits.
  6. Using exhaust fan for purifying inside air and expelling heat outside.
  7. Using vacuum cleaners for removing dust and spill over liquids.
  8. We should give most importance on which items are need rather than decorative items.
