Maerua angolensis

The Bead-bean tree typically needs about a gallon of water on a regular schedule. For potted plants, water them deeply until you see water dripping from the bottom of the pot. Then, wait for the soil to dry before watering again. To determine the amount of water given in a week, you can use a water calculator or moisture meter. During the flowering period, provide ample water but allow the moisture to evaporate to prevent root rot. If the Bead-bean tree is planted outdoors and receives sufficient rainfall, it may not need additional watering. However, when the tree is young or newly planted, ensure it receives 1-2 inches of rain per week. As the Bead-bean tree grows, it can rely solely on rainfall. Only in very hot weather or when there is no rainfall for 2-3 weeks should you consider giving the tree a thorough watering during the cooler parts of the day to prevent heat damage. Additional watering will be necessary during prolonged dry spells.

If you are planting Bead-bean trees in the ground, they mostly rely on rain. However, if there hasn't been any rainfall for 2-3 weeks, you may need to water them deeply. It's best to water them in the morning during the summer, as a large temperature difference between the water and root system can stress the roots. Avoid watering the bushes when it's too hot outside. Start mulching them in the spring, when the ground is not too cold. The age of the plants is important. Newly planted ones often fail to grow due to lack of water, so make sure to water them enough. Once they are established, you can reduce the watering schedule. During the fall and winter, especially if there is a water-retaining material in the soil, water them less. The dry winds in those seasons can dry them out, and newly planted ones are particularly at risk of drought during windy winter, summer, and fall. Windy seasons require more watering. Plants in pots dry out faster, so they need to be watered more frequently. If you notice less blooming and drying leaves, it may be a sign that they need more water. Watering potted plants can be complex and the frequency may vary. Avoid letting the potted plants sit in water by not using containers with saucers, bowls, or trays. Too much watering in the fall can cause mottled or yellowish foliage. Regardless of the climate or season, it's important to prevent overwatering. When the Bead-bean tree starts flowering, you may want to increase the watering frequency, but once they are fully grown, you can reduce it again. Water them with an adequate amount of water every 3 to 5 days, but don't stick to a strict schedule. Check the soil moisture by sticking your finger in the pot or using a moisture meter if you're unsure. Too much watering can lead to root rot and plant death, so be cautious not to overwater or underwater regardless of the climate or season in your area.

A Bead-bean tree needs a generous amount of sunlight to thrive, ideally flourishing in conditions of full sun, which means it requires more than 6 hours of sunlight daily. However, it's also capable of adapting to partial sun exposure, about 3-6 hours of sunlight. It's essential to monitor the movement of sunlight through your garden to identify spots that offer an ideal balance of light and shade, ensuring the optimal growth and happiness of your plants.

When natural sunlight is not sufficient, especially during winter or in less sunny spaces, artificial lighting can be a vital supplement for indoor Bead-bean trees, promoting faster and healthier growth. LED lights are recommended due to their ability to simulate specific wavelengths needed by plants. Full sun plants require 30-50W/sq ft, partial sun plants need 20-30W/sq ft, and full shade plants need 10-20W/sq ft of artificial light. The light source should be placed 12-36 inches above the plant to mimic natural sunlight, and most plants will require 8-12 hours of light per day.

When Bead-bean trees do not receive adequate sunlight, they may exhibit several symptoms indicating light deficiency. These symptoms include smaller new leaves, leggy or sparse growth, faster leaf drop, slower or halted growth, lighter-colored new leaves, and conditions like chlorosis and sunscald. Leaf curling, wilting, and leaf scorching are also signs that the plant is either getting too much sunlight or struggling under inadequate light conditions.

To remedy light deficiency for Bead-bean trees, gradually adjust the plant to receive at least 6 hours of direct sunlight daily. For indoor plants, consider using a south-facing window or artificial grow lights to ensure adequate light exposure for 8 hours daily. For outdoor plants, move them to sunnier spots progressively each week to avoid sunburn. For plants that have outgrown their location or are in heavily shaded areas, reducing obstructions like pruning nearby trees or transplanting the plant to a sunnier location might be necessary. It's important to note that while parts of the plant that have already been affected might not recover, new growth should be healthy following these adjustments for increased light exposure.
