How to care indoor plants?
Know the trick to help your plant survive for years
Considering pollution inside the house, indoor plants are not any more luxurious commodity, these have become necessity for the modern sealed houses. In addition to aesthetic, indoor plants are indispensable for a number of scientific reasons such as, these plants help regulate humidity levels, clean several types of air contaminants, absorbs airborne bacterias, molds and add fresh oxygen to the surroundings. Bring nature home with indoors plants. There are houseplants in all sorts, shapes and sizes – some loved for their flowers, others for their elegant foliage and most for their fairly low maintenance and air purification.
Several houseplants are easy to grow, provided they are given appropriate opportunities in order to thrive. Proper watering and lighting are the most important components of indoor plants care, for some type of indoor plants humidity and temperatures also play a key role. Tropical plants thrive in warm, humid environments, while cacti and succulents prefer hot, dry climates. Of course, home can’t be everything to every plant, but you can take plant needs into consideration when choosing the plants. And, with a few tricks, you can convince your green friends that they are living in their ideal environment.
The first thing to consider when selecting a houseplant is where you want to keep it. Then match the space and lighting with the plant’s requirements. Do you have a big spot by a sunny window or a small space with moderate light? Next ask yourself if you are looking for a plant with beautiful green leaves or would prefer a flowering plant? Third consideration is how much time you can devote to a particular plant?
Plants require sunlight in order to photosynthesis, the quality, duration, and intensity of light affect a plant growth. Avoid putting indoor plants in direct sunlight as that may burn their leaves. Instead, offer them plenty of indirect light by putting them in a well-lit room, fluorescent lights can work as an alternative to sunlight for some plants:
Give flowering plants 6-8 hours of light per day.
Give foliage plants 4-6 hours of light per day.
Potting soil should be kept moist, but not wet. Of course, there are always exceptions — succulents, and other thick-leafed plants do best when the soil dries out between watering. If the soil is kept too dry or too damp the plant’s roots will begin to die, which can lead to inadequate growth or even death of the plant.
There are several methods to determine when a plant needs water. If the potting soil becomes lighter in color or cracked, it’s probably time to water. Pick up your plant and gauge the weight after watering. After a few practice lifts, you’ll be able to tell if the plant needs water just by picking it up. You can always stick a finger in the soil to determine how moist it is below the surface. Signs of underwatering include:
Slow leaf growth
Premature dropping of flowers or leaves
Brown, yellow or curled leaf edges
Too much water is just as detrimental as too little. Frequent watering forces air from the soil and opens the door for root-killing bacteria and fungus to move in. Overwatering is the number one killer of houseplants. Signs of overwatering include:
Fungus or mold on the soil surface
Mushy brown (maybe stinky) roots at the bottom of the pot
Standing water in the bottom of the container
Young and old leaves falling off at the same time
Leaves with brown rotten patches
Watering on Demand
|Plants requiring more water||Plants requiring less water|
|– Flowering plants
– Plants potted in clay pots
– Plants grown in small pots
– Actively growing plants
– Plants located in direct sunlight
– Large-leaved or thin-leaved plants
– Plants that are native to wet areas.
|– Resting or dormant plants
– Recently repotted plant
– Plants grown in high humidity

– Plants grown in a water retentive mix
For those who are too busy to keep up with a regular watering schedule, which requires checking individual plants every 3-4 days, they must pick drought tolerant plants or go for several self-watering devices available.
How to Water
Plants can be watered from the top down or bottom up. When watering from the top, try not to wet the foliage, while ensuring the entire soil mass is moistened. Water should be coming out of the drainage holes in the bottom of the pot.
If you prefer to let your plants do the work, set the plant in a dish of water and the roots (and capillary action in the soil) will pull up whatever they need. This method, known as bottom-watering, is a more thorough, if time-consuming, way to water plants.
Tip: Be sure to dump any standing water from the saucer one hour after watering.
Good drainage is essential to healthy houseplants. Start with a good, organic potting soil (not regular soil) that has been mixed specifically for indoor gardening. Choose a container with drainage holes, or put a layer of pebbles in the bottom of a container without holes. The point is to not let the plant stand in water. From time to time, check that the drainage holes have not been clogged. And always empty standing water (don’t run it back through the plant’s soil).
As with watering, every plant has different light requirements. Many plants prefer direct sunlight, but this may be hard to get inside a house. Placing a plant in a window might offer enough light, but some houseplants will need supplementing from a grow light. Flowering plants generally do best in moderately bright light and for this reason windows located on the south, east or west side of the house are best for potted flowering plants.
Foliage plants can be divided into three categories: those requiring low light, moderate light and high light. A dimly lit room should suffice for those few plants willing to survive in low light areas. Moderate light-needing plants will prefer a north-facing window, light diffused through a thin curtain or daylight without direct sun. Indoor plants that prefer high light will need to be in a south-facing window or under a grow light. Some plants will benefit from being moved outside in the summer to get a little extra light.
Do not let plants get to the point where they are wilting or the soil is pulling away from the edge of the container. These symptoms indicate dehydration and at this point the plant is already seriously stressed and the roots may be damaged.
Many houseplants thrive in temperatures between 18-24° during the day and 12-18° at night. Of course, temperature preferences vary from plant to plant with tropical plants liking temperatures around 30° (or higher) and other plants growing better in cooler temperatures.
Most plants thrive in high humidity — around 80%. Unfortunately, most homes are much drier, especially in the winter when forced heat can even further drop the humidity. Using a humidifier can help, but there are other ways to increase the moisture in the air near your plants. A small tray containing pebbles and water can boost local humidity as can grouping plants more closely together. Daily misting of the plant’s leaves can help as well. For some plants, such as gardenias and orchids, keeping them in a bathroom or the kitchen can help.
Every time a plant is watered nutrients leach out of the soil. Even if that didn’t happen, plants would quickly deplete the nutrients in their soil. Unlike plants living outside, houseplants don’t have a regular source of nutrient replenishment unless you fertilize them regularly. Fertilize once a month when plants are flowering or growing. During the winter, when plants are dormant or generally not growing much, fertilizer can be withheld.
If a plant is dropping its lower leaves, showing weak growth or an overall yellow-green color, it may need more fertilizer. It might also need more light or less water, so take the time to analyze all conditions before pouring on more plant food. Adding fertilizer when a plant does not need it can be worse than doing nothing at all.
Tip: If a plant is wilted, water well first then apply a fertilizer later — after it has recovered.
Choose an organic fertilizer specific to houseplants and read the instructions carefully. While natural fertilizers are less likely to burn or harm your plants than a synthetic fertilizer, it is important to apply the correct amount. In general, plants grown in low light will not require as much fertilizer as plants grown outside or in bright light.
To start, use about 1/4 the amount of fertilizer recommended on the label once a month. Then, if overall plant color becomes lighter, increase fertilizer applications to every 2 weeks. On the other hand, if the new growth is dark green, but the leaves are small and the space between the leaves seems longer than on the older growth, fertilize less often.
Tip: Soluble salts from synthetic fertilizers can build up over time and create a crusty layer of salt deposits on the soil surface. Remove this layer and leach the soil every 4-6 weeks with generous amounts of water to help avoid toxic salt build up. Excessive salts can damage roots and make the plant more susceptible to disease and insect attack.
If your plants are thriving and growing the way you want them to, eventually they will need a bigger pot — or some fresh potting mix. Repot plants in the spring when they are just starting to grow. Vigorous root growth will allow the plant to adjust to its new container quickly.
When it comes time to repot, choose an organic soilless medium made specifically for potting houseplants (maybe even specific to your species of houseplant).
Choose a pot that is bigger than the current container, but not huge. A pot that is too-big can encourage root rot and other problems because the soil will remain wet for days, or even weeks before it can be used by the plant.
Take care with the root system when repotting to avoid damage. Carefully firm the soil around the root ball without compacting the soil. Leave enough space at the top of the new container for water and water thoroughly.
