Interior Plant Tips



Plants for use inside the house or office can be grown organically. Plants not only have far fewer problems under the natural program, but they also provide a benefit other than just looking nice and softening spaces. They also help clean the air.


Potting soil for interior plants should be the same used for outdoor potted plants. The two best mulches for potted plants are shredded cedar and lava gravel.


The fertilizer program is simple. In fact, the two most common mistakes made on house plants is too much water and too much fertilizer. Adding a mild organic fertilizer once a year in the spring is usually plenty. Compost, earthworm castings or compost tea along with a one time application of lava sand is all I use. Use about ¼” of lava sand and gently work in.



Adding a tablespoon of apple cider vinegar per gallon of irrigation water will help keep your potted plants healthy and vibrant.


The easiest plants to grow tend to be the most effective at air purifying. My recommended list is as follows:


Bright Areas

Aloe vera

Areca palm

Bamboo palm

Christmas cactus



Dwarf banana

Lady palm





Boston fern

Corn plant dracaena


Heart leaf philodendron

Janet Craig dracaena

Pothos ivy

Rubber plant



Spider plant

Warneckei dracaena


Shadiest Areas


Heart leaf philodendron

Red emerald philodendron



ZZ Plant


An excellent book on the air purifying properties of plants is How To Grow Fresh Air by Dr. B.C. Wolverton, Penguin Books.
