FOOD AND AIR
The soil of plants must be "well enriched" ,which means that the soil should be rich enough for the growth of the plant and able to retain moisture.The soil may be enriched by adding organic and inorganic manures.Organic manure is a manure made from wastes of plants and animals(decomposed leaves and cow dung). An inorganic manure is made chemically and is, therefore also known as chemical fertilizer.These are available in small packets.The manure is added to the soil in the plants,three to four times in a yer-once before winters, then before the onset of summers and again before the rainy season.The soil is loosened a little by digging and the manure is put around the plant on top of the soil.While digging the soil, take care not to damage the roots.The day you loosen the soil, do not water the plant that same day.The interval between loosening and watering of soil, helps in the aeration of roots and absorption of water from a greater depth.

Rooms with indoor plants placed in it, should let some fresh air into the rooms,even if it's only through the wire mesh (jaalis) on the windows.

Top-Dressing Large Houseplants
When plants inpots become too large to be re potted, they are top dressed in spring.Allow the surface soil to dry slightly, then use small trowel(tool for digging)to scrape away the top 1-1.5 inches.

Replace the surface soil with potting soil. Leave a space between the top of the soil and the rim of the pot,so that the plant can be watered without the water over flowing, when the soil in the pot becomes dry.
