What are the fertilizers for Bougainvillea
For information about the fertilizers for Bougainvillea and tips on how to care for them to ensure continuous blooming, keep reading! Bougainvillea is a plant with a strong blooming capability. Many people grow it to ensure it blooms throughout the year. To achieve this, you need to provide it with fertilizer. Most people would buy a pile of fertilizer and use it immediately, but actually, Bougainvillea is not as difficult to care for as we think. You don't need too much fertilizer for blooming. Usually, experienced gardeners will prepare three types of fertilizers, and any more would be a waste. If you choose the right fertilizers at the appropriate time, the plant will have lush green leaves and continue to bloom.
1. Bloom-Boosting Fertilizer
Since Bougainvillea is a flowering plant, the fertilizer we must prepare is bloom-boosting fertilizer. What kind of fertilizer should we use? Generally, as the plant grows, it keeps producing flower buds on the branches, so the fertilizer should have a high phosphorus content and not lack other elements. For example, using "Flower多多 No. 2" fertilizer regularly can provide sufficient phosphorus to ensure flower bud differentiation, adequate potassium for more developed roots, and enough nitrogen for the terminal buds to continue growing, which is the best fertilizer for it.
However, some people may find that their Bougainvillea blooms very few or not at all due to environmental conditions. For Bougainvillea that doesn't bloom, you should use monopotassium phosphate. Using it once can cause the plant to bloom profusely. You can also prepare some as a backup in case your Bougainvillea is reluctant to bloom, so you can use it directly.
2. Green Leaf Fertilizer
Bougainvillea naturally has lush green leaves, so why prepare green leaf fertilizer? Because Bougainvillea is a plant that thrives in acidic conditions. If you let it grow and bloom for a long time, you may notice that its leaf veins turn green, while other parts turn yellow, and the whole plant stops growing, which is caused by alkaline soil. Alkaline soil prevents the plant from absorbing iron, leading to poor root growth and eventually a僵苗 (stunted growth) state, with all leaves turning yellow and falling off.
So, we need to prepare some ferrous sulfate. Ferrous sulfate should be supplemented every two months or so. You don't need to use too much. This way, the soil remains acidic and doesn't lack iron, allowing the plant to grow quickly and maintain green leaves. Remember, when using ferrous sulfate, it's best to mix it with some vinegar to prevent oxidation and ensure quick absorption.
3. Soil Fertilizer
Soil fertilizer refers to keeping the soil fertile at all times. If you forget to fertilize or don't fertilize your Bougainvillea properly, the soil will become impoverished and may become compacted, ultimately leading to weak roots. We need to ensure the potting soil contains enough nutrients. Therefore, a type of fertilizer that should always be kept at home is slow-release fertilizer, which should be balanced in nitrogen, phosphorus, and potassium. This fertilizer releases nutrients slowly. You only need to sprinkle ten or eight granules, and you won't need to add more fertilizer for about half a year. This way, the soil can provide a weak nutrient supply for the Bougainvillea to grow, and it won't have any issues even if you occasionally forget to fertilize. Of course, if you don't want to use slow-release fertilizer, you can use some well-fermented sheep manure, sprinkling it on the soil surface every one to two months. This not only ensures the soil's fertility but also makes it looser and more breathable.
Caring for Bougainvillea is relatively simple. If you want it to grow well and bloom profusely, these three types of fertilizers must be prepared. Then, place it in a location that gets sunlight throughout the year to ensure adequate light. To make it bloom, you can control the watering by waiting until the soil is completely dry before watering thoroughly. Make sure to use well-draining soil and grow it in a small pot. As long as the temperature in your home does not drop below 10 degrees Celsius, it can bloom all year round.
