The watering frequency depends on the type of plant, soil, and climate. Generally, it's best to water when the top inch of soil feels dry. Ensure thorough watering until excess water drains out from the bottom of the pot.
Most plants thrive in well-draining, nutrient-rich soil. Use a general-purpose potting mix for houseplants, and amend garden soil with compost to improve texture and fertility. Specific plants may have unique soil requirements, so check individual care guides.
Light requirements vary widely among plants. Most houseplants prefer bright, indirect light, while succulents and cacti need direct sunlight. Shade-loving plants thrive in low light conditions. Always check the specific light needs for your plants.
Fertilize during the growing season (spring and summer) when plants are actively growing. Use a balanced, water-soluble fertilizer every 4-6 weeks. Reduce or stop fertilizing in fall and winter when growth slows down.
Pruning helps maintain plant health and shape. Remove dead, damaged, or diseased branches and spent flowers. Use clean, sharp tools to make precise cuts. Pruning encourages new growth and flowering.
- Overwatering signs include yellowing leaves, root rot, and moldy soil. Underwatering signs include wilted, dry, or brown leaves. Adjust your watering schedule based on these signs and the plant’s needs.
Increase humidity by misting plants regularly, placing a tray of water and pebbles near the plants, or using a humidifier. Grouping plants together also helps create a more humid microenvironment.
Identify the pest type first (e.g., aphids, spider mites, mealybugs). Remove visible pests by hand or with a strong stream of water. Use insecticidal soap or neem oil as treatments. Isolate the infested plant to prevent spread to other plants.
Repot when the plant outgrows its current pot or roots start emerging from drainage holes. Choose a pot one size larger, gently remove the plant, loosen the roots, and place it in the new pot with fresh potting mix. Water thoroughly after repotting.
