 The danger for Pets and Children- some indoor plants are poisonous and cause harm to pet and children (on physical contact). e.g. - Philodendrons, Pothos,

Arrowheads, Lily, Dieffenbachia, Caladium, Ivy, Sansevieria etc.

 Allergens- the major disadvantage is they can cause allergies because of spores, pollen grains. The mould can be formed in moist soil under low light.

 Lack of maintenance:

1. Brown leaf tips may appear because of overuse of fertilizer, lack of water or excessive fluoride in irrigation water. 2. Leaf yellowing and dropping are caused by air pollution, cold weather, lowintensity light, poor water drainage, overwatering, or lack of water. 3. Slow growth or light green or yellow foliage is caused by too much light, poor root system, root rot or lack of fertilizer. 4. Small leaves and spindly growth are caused by lack of sunlight. 5. Small leaves and stunted growth may be caused by lack of water or lack of fertilizer. 6. Small new leaves and leaves curled under may be caused by bright light.
