Indoor Plants As with any house guests,indoor plants require a certain amount of basic,regular attention if they are going to feel at home. The first consideration when purchasing plants is to make reasonably sure that they are suitable for the condition in which they are going to be housed. A general rule for most plans being brought indoors for the first time is to ensure that they have reasonable temperature of not less than 60 degrees Fahrenheit,a position out of cold air,safe from pets and not exposed to strong sunlight. Plants love company. When plants are growing together,they create an atmosphere of damp around themselves which is far more beneficial than hot dry conditions. A group of plants will also present a more pleasing picture and provide an opportunity for a creative arrangement. There is no secret to this. Just rely on your natural feeling for harmony. Watering and feeding plants are probably the two areas of care that are the least well understood,but,again,if you follow a few simple rules,your plants should do well. Cold Slightly warm water is therefore the answer. It is usually better to pour water on to the soil on the surface of the pot rather than put the water into the pot holder at the bottom. Avoid giving small amount of water at regular intervals- it is much better to wet the soil right through the pot in one go and then to allow it to dry noticeably before giving it a further watering. The majority of indoor plants will be in active growth from March until October,and during this time,the established ones will benefit from regular feeding. This may mean feeding with a weak liquid fertilizer  at each watering or at intervals of a week or ten days with fertilizer at a standard strength. It is important,however,to ensure that plants are not fed when growth is inactive,when the soil in the pot is dry,or too soon after the plants has been potted up. What is the best time to feed the plants?
When the soil is dry. When their growth is active. When the temperature is high. When they have just been planted.
