Flower Varieties & Their Defining Characteristics
There are two main varieties of Nymphaea caerulea, the Egyptian Blue Water Lily and the Egyptian White Water Lily. The Egyptian Blue Water Lily has upright blue petals and thick yellow stamens, with the leaves growing up to 16 inches. It is native to Lake Nasser and the Nile Valley throughout Africa. The Egyptian White Water Lily is white in color, with a slightly different leaf shape than the blue variety. The petals are flat, instead of the erect petals the blue variety has. The flower thrives in full sun and has a sweet smell.
How To Pot and Repot
Potting the Egyptian Blue Water Lily is quite simple and requires just a few steps. Start by selecting a heavy potting container. The pot should be around 8-10 inches wide and 8-12 inches deep so that the roots of the plant have enough room to grow. Make sure the pot has proper drainage holes. Next, mix the soil with organic compost and perlite. Place the potting mixture in the pot and gently place the water lily in it. Press the soil around the roots, making sure that the plant is firmly rooted in the container. Water the pot and keep the soil moist while the plant is taking root. Once it has taken root, the pot should be moved to a site with direct sunlight and should be fertilized regularly. When the plant starts getting bigger, it should be repotted in a larger container.
How To Prune
Pruning the Egyptian Blue Water Lily is essential for healthy and beautiful blooms. You should start by cutting off any browning, aging or unhealthy foliage. Then you should prune off any flower buds that have started to wilt, as these can stunt the growth of the plant. Finally, remove any overlapping leaves or flower buds to encourage the plant to bloom and retain its current shape and form. Pruning can be done with scissors or pruning shears and it is important to make sure that all the leaves and bud ends are cut cleanly and at the right angles.
How To Propagate
Propagation of the Egyptian Blue Water Lily is done mostly through rhizome division and cuttings, since the plants are not able to produce seeds. The rhizome division is done by cutting the existing plant in sections using a sharp knife and replanting the separated pieces in new pots, while the cuttings should be taken from the stem of the plant and planted in wet soil. New plants will start forming and growing in the new pots. Also, seed can be obtained from seed banks. Once the seeds are collected, soak them in warm water for 1-2 days and then sow them in moist soil, after which the plants can be moved to a sunny area and given regular water and care.
Common Pests & Diseases
The Egyptian Blue Water Lily is susceptible to several pests and diseases. The most common pests include aphids, mealybugs, scale insects, and thrips. These pests can cause leaf discoloration, stunted growth, and eventual death of the plant. Diseases like root rot and fungal diseases can also be found on this flower. If these pests or diseases are spotted, it is important to immediately treat the plant with the appropriate measures. This includes using pesticides to get rid of pests and using fungicides to control fungal growth. Keeping the plant away from standing water and wet soil can help prevent the growth and spread of pests and diseases.
