How to Care for Plants

Provide ample light for your plants. One of the key considerations when growing plants indoors is ensuring they receive sufficient light. While plants placed near a living room table may look beautiful, if the spot is too far from a window, the plant may not survive long. Research the light requirements of the plant you are growing and move it to a suitable location. Note that south-facing windows in a home receive the most light, while north-facing windows receive the least. Basic guidelines for plant light requirements are as follows:

• Plants needing 'full sunlight' should be placed where they can receive direct sunlight for 4-6 hours daily.
• Plants needing 'partial sunlight' should be placed where they can receive direct sunlight for 2-3 hours daily.
• Plants needing 'shade' should be placed where they can receive direct sunlight for 1 hour daily.

Water your plants regularly. Maintaining the right balance when watering indoor plants can be tricky: too much water and the roots may rot due to poor drainage, while too little water can cause the plant to dry out. The exact amount of water needed varies by plant, as some species require consistent moisture year-round, while others (like cacti and succulents) only need watering every few weeks. However, most plants thrive when watered 2-3 times a week. You can use a spray bottle or watering can to moisten the soil without over-saturating it.

• Insert your finger into the soil up to the second knuckle to check moisture levels. If the soil feels dry, it’s time to water. If it feels damp, wait another 1-2 days.
• Always use lukewarm water, as cold water can shock the roots and harm the plant.
• Deep water your plants about once a month. Place the plant in a sink and let water run through the soil to prevent salt buildup.

Fertilize your plants every few weeks. Fertilizers are substances added to soil to provide essential nutrients. Fertilizing indoor plants every 2-3 weeks is especially important, as potted plants don’t receive natural nutrients like outdoor plants. Most fertilizers are labeled with a three-number ratio, such as 10-20-10, representing nitrogen, phosphorus, and potassium content. Each plant has unique needs for these minerals, so choose a fertilizer accordingly. However, balanced fertilizers like 6-12-6 or 10-10-10 are generally suitable for most plants and are a good starting point.

• Apply fertilizer directly to the soil as directed on the packaging.
• You can mix liquid fertilizer with water in a watering can and apply it to the plants.
• There’s no need to mix fertilizer into the potting soil, as it will gradually dissolve and absorb into the soil.

Dust your plants regularly. Over time, indoor plants accumulate a layer of dust. This not only dulls their natural beauty but also hinders growth by clogging the leaf pores. Depending on the plant’s size, you can clean it using a damp cloth or by rinsing it under a faucet. For the cloth method, mix warm water with a small amount of dish soap or plant-safe soap, dip the cloth, and gently wipe each leaf. For rinsing, place the plant in a sink, run lukewarm water, and use your hands or a clean cloth to wash the leaves.

• Rinsing is ideal for smaller plants, but ensure excess water doesn’t pool in the pot.
• You can also use commercial plant-cleaning sprays available on the market.

Keep plants away from vents. Indoor humidity is often lower than outdoor levels, which can dry out houseplants. While regular watering helps, a bigger issue is placing plants too close to air vents. Whether it’s a heater or air conditioner, constant airflow can dry out the leaves and risk killing the plant. To solve this, move plants away from all vents. You can also use a humidifier to increase air moisture while adding a decorative touch to the room.

Ensure your plants receive adequate water. Outdoor plant care heavily depends on weather conditions and the surrounding environment. Therefore, the amount of water your plants need varies based on the climate and soil in your area. A general rule is to water your plants 2-3 times a week using a watering can or a sprinkler system. Make sure the soil remains moist but not soggy, and avoid letting it dry out completely.

• Research the ideal water requirements for each plant, as some species need more water while others thrive with less.

Regularly weed your garden. Weeds can sprout overnight and ruin the beauty of your garden. Not only are they unsightly, but they also compete with your plants for space and nutrients. Remove weeds as soon as you spot them. Grasp them firmly at the base and pull straight up to ensure the roots are removed, slowing their regrowth.

• You can use herbicides, but most are non-selective and may harm surrounding plants, not just weeds.
• Check for weeds growing beneath shrubs or bushes.

Apply garden mulch every few months. Mulch is an organic material spread over the soil to suppress weeds and retain moisture. It also enriches the soil as it decomposes, promoting healthier plant growth. You can purchase mulch at most gardening stores and apply a layer 2.5 cm to 5 cm thick across your garden.

• Avoid covering the base of plants, as mulch can hinder their growth, especially for young plants and shrubs.
• Compost can be used as an alternative to mulch, though it doesn’t prevent weeds as effectively.
• For long-term weed control, combine mulch with garden fabric to nearly eliminate weed growth.

Remove dead or diseased plants. Plant diseases can spread rapidly if not controlled. The same applies to damaged plants. If you don’t remove dying branches, the damage can spread further. Whenever you notice branches turning brown, dry, brittle, or diseased, use pruning shears to cut them off at the base. Dispose of the cuttings away from the garden to prevent the spread of disease.

Deadhead spent flowers. This encourages new growth and removes wilted blooms. Use garden scissors to cut the flowers just below the bud. Within a few days, you’ll notice new buds forming and blooming.

• To promote leaf growth, trim flower buds before they bloom, helping the plant conserve energy.
• This method works for most flowering plants, such as marigolds, cockscombs, and zinnias.

Fertilize your plants once a month. Outdoor plants absorb more natural nutrients from their environment compared to indoor plants, meaning they require less frequent fertilization. Choose a fertilizer that meets the specific mineral needs of your plants or opt for a balanced formula like 6-12-6 or 10-10-10, available at nurseries. Apply the fertilizer to the soil every 4-5 weeks, following the instructions on the packaging.

• Mix the fertilizer into the top few centimeters of soil to prevent it from washing away or spreading to areas where it’s not needed. Leaving fertilizer on the surface allows nutrients to evaporate rather than soak into the soil.
• Consider using organic compost. Chemical fertilizers often waste nutrients due to their rapid dissolution, which outpaces plant absorption. Organic compost, on the other hand, releases nutrients slowly and provides additional trace elements.
• If unsure about the right fertilizer, consult staff at your local nursery.

Improve drainage in poorly draining soil. If your garden or plant pots frequently have standing water, the soil’s drainage is inadequate. Poor drainage harms plants, as waterlogged roots can rot and eventually kill the plant. To fix this, carefully dig up the plant and its root ball, place it on a tarp or in another pot, and mix organic compost or peat moss into the soil before replanting.

• If the entire area has poor drainage, consider digging up the soil and mixing it with sand to enhance water flow.

Relocate overcrowded plants. If you’ve planted too many seedlings close together, they’ll compete for space and nutrients as they grow, hindering their development. Dig up the overcrowded plants and transplant them to larger pots or different areas in the garden. Fill the holes with garden soil.

• Use store-bought potting soil instead of garden soil to avoid introducing pests, diseases, or weeds.
• Overcrowding occurs when plants grow intertwined or their stems become thin and weak.

Avoid applying mulch too thickly. While mulch benefits plants by adding nutrients and suppressing weeds, excessive mulch can cause problems. Thick mulch layers can block new shoots from emerging. Keep mulch layers under 5 cm thick. If plants struggle after mulching, remove 2.5 cm to 5 cm of mulch and monitor for improvement.

• Mulch piled too high around plant bases can block sunlight and hinder growth. Keep mulch away from the base and stems of garden plants.

Remove diseased or dead plants. Plant diseases can quickly spread throughout your garden if left unchecked. The same applies to damaged plants; if you don’t remove dying branches, the damage can spread to the entire plant. Whenever you notice yellowing, browning, dry, brittle, or diseased branches, use garden shears to cut them off at the base.

• Dispose of the cuttings instead of composting them, as diseased plants can still infect nearby healthy plants.

Avoid overwatering. Even if you think you’re watering correctly, yellowing and drooping plants may indicate overwatering. Most plants don’t need daily watering and actually thrive when watered deeply every few days. Only water when the top 2.5 cm of soil is dry. If you water every time the surface looks dry, you’re likely overdoing it. For indoor plants, consider using a spray bottle instead of a watering can to avoid overwatering, as it releases water in smaller, controlled amounts.

Don’t plant too deep. If your plants keep wilting and dying without explanation, they might be planted too deep. Roots need to be relatively close to the surface to absorb nutrients from the topsoil and access sunlight. Carefully dig up the plant and replant it so the roots are level with or just below the soil surface. If any roots are exposed, cover them with a layer of mulch for protection.

• When transplanting potted plants into the garden, plant them at the same depth as they were in the pot.
• If most roots are above the soil, the plant will also struggle. Ensure the roots are within the topsoil layer.
