Sunlight and Watering Needs
Bring on the Sunshine
Bougainvillea loves the sunshine! This plant requires at least 6 hours of sunlight to thrive.
However, too much direct sunlight can be harmful, so it’s important to provide some shade during the hottest part of the day. If you’re growing your bougainvillea indoors, place it in a bright, sunny window.
Watering Tips
One of the biggest mistakes people make when caring for bougainvillea is overwatering. This plant prefers well-drained soil that stays slightly moist.
Water your bougainvillea deeply once a week during its active growing season (spring through summer) and reduce watering in the winter months when growth slows down. Check soil moisture levels before watering; if the top inch of soil is dry, it’s time to water.
Avoid Overwatering
Overwatered bougainvillea often suffer from root rot and other fungal diseases that can cause yellow leaves or even death. Make sure that your pot has drainage holes to prevent water from pooling around the roots and causing damage. If you notice any signs of overwatering, such as wilting or yellow leaves, reduce watering frequency immediately and allow the soil to dry out slightly before watering again.
Providing adequate sunlight and proper watering are crucial for keeping your bougainvillea healthy and blooming all season long. Remember to give your plant enough sun without overexposure or underwatering in order to ensure its beauty lasts throughout its life cycle.
Soil Requirements
Bougainvillea is a tropical plant that prefers well-draining soil with a slightly acidic pH level between 5.5 to 6.5. The ideal soil mixture for bougainvillea is one part sand, one part peat moss, and two parts loam or potting mix. This mixture allows for good drainage while retaining enough moisture for the plant to thrive.
If you are planting bougainvillea in an existing garden bed, make sure the soil has been amended with organic matter such as compost or aged manure before planting. This will help improve soil structure, drainage, and nutrient availability.
Tips on Fertilizing
Fertilizing is important to promote healthy growth and blooming in bougainvillea plants. Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium (NPK) every four to six weeks during the growing season (spring through fall). Avoid using fertilizers high in nitrogen as this can cause the plant to produce more foliage than flowers.

Uninvited Guests: Common pests that can affect bougainvillea’s health and blooming potential
While bougainvillea is a resilient plant, it can fall victim to a range of common pests that feed on its leaves and sap, causing damage to the plant and impacting its ability to bloom. Some of the most common pests that can affect bougainvillea are spider mites, mealybugs, aphids, caterpillars, whiteflies, and scale insects.
Spider mites are tiny arachnids that build webs on the leaves of the plant. They suck sap from the leaves causing yellowing and eventual leaf drop.
Mealybugs secrete a sticky substance called honeydew which attracts ants which then protect them from predators. Aphids suck sap from new growth shoots and often leave behind sticky residue leading to secondary fungal growth.
Caterpillars chew holes in leaves making plants look unsightly while whiteflies cause yellowing and stunting due to their feeding activity on the underside of leaves. Scale insects create their own armor-like covering which protects them as they feed on plant sap.
Common Bougainvillea Pests and Their Treatments

Aphids
Small, soft-bodied insects that cluster on new growth, causing yellowing and curling of leaves
Use insecticidal soap or neem oil, or spray with a strong stream of water to knock them off the plant
Caterpillars
Caterpillars may eat leaves and can cause significant damage to the plant
Handpick the caterpillars off the plant, or use Bacillus thuringiensis (Bt) insecticide
Spider Mites
Small, spider-like pests that suck the sap out of leaves, causing a mottled appearance and eventual yellowing and death of leaves
Use insecticidal soap or neem oil, or spray with a strong stream of water to knock them off the plant
Scale
Small, immobile pests that attach themselves to leaves and stems, causing yellowing, stunted growth, and leaf drop
Use insecticidal soap or neem oil, or scrape the scales off with a soft-bristled brush and wipe the plant down with rubbing alcohol
Natural vs Chemical Treatments: Keeping pests at bay
When it comes to keeping these uninvited guests at bay there are two main options – natural remedies or chemical treatments. Natural remedies include solutions such as spraying plants with water or insecticidal soap (made by combining dish soap with water) or rubbing alcohol onto affected areas of plants with a soft cloth or cotton ball. There are also many essential oils that act as an effective pest repellent for bougainvillea including lavender oil sprayed onto foliage or placing eucalyptus branches near plants.
If natural remedies don’t do the trick then chemical treatments may be needed. The most common chemicals used for pest control in bougainvillea are neem oil, malathion, and pyrethroids.
