Plumeria pudica is a delightful choice, and caring for it properly can really enhance its growth and bloom potential. Let's break down each aspect of care you're curious about:
Light: Plumerias thrive in bright, direct sunlight. A south-facing window can often be ideal, as it will provide the intensity and duration they crave. If natural light is insufficient, especially during the shorter days of winter, you might consider supplemental grow lights. LED grow lights can effectively mimic sunlight and may help maintain healthy growth if your indoor light levels drop.
Watering: These plants prefer a balance when it comes to moisture. You're right; they don't enjoy being too wet, which could lead to root rot. A good rule of thumb is to allow the top couple of inches of soil to dry between waterings. You might find that in winter, you need to water less frequently compared to the growing season. Be observant of the plant's response and adjust your schedule accordingly.
Soil: Plumerias require well-draining soil. A cactus or succulent mix is often recommended as it provides the right drainage. You can enhance drainage further by adding perlite or coarse sand. This mix minimizes the risk of waterlogged roots, which is crucial for their health.
Fertilization: During the growing season (spring through early fall), a balanced fertilizer with a slightly higher phosphorus content can promote blooming. Look for something with a ratio like 10-30-10. Fertilize every 2-4 weeks, but be cautious not to overdo it, as too much fertilizer can harm the plant. During the dormancy period, you can halt fertilization or significantly reduce its frequency.
Maintaining good air circulation and monitoring for signs of pests or disease will also contribute to a thriving Plumeria. I've found that each plant can be a bit unique, so a little observation can go a long way in fine-tuning your approach. How often are you currently watering, and have you noticed any changes in the plant since you got it?
