Nepenthes rajah x lowii Potted
This is another dream cross that is super exciting! This hybrid does occur in nature so we have some idea what it will look like! These horticulturally produced ones however, are already showing significantly better color with dark purple! They will require ultra highland conditions but be easier to grow than either parent. This is a must have for the Nepenthes collector!
These are from assorted clones in tissue culture from Borneo Exotics, BE-4502. The first two photos are of the parents in this cross; Nepenthes rajah and Nepenthes lowii.
Sun: Nepenthes should be grown on a sunny windowsill where the plant receives direct light for at least four hours daily. Grow in a cooled greenhouse in full sun, but we recommend 30% shade cloth overhead in summer. Grow in a terrarium or shelf under grow lights for the best color and pitcher formation. When grown under lights, lights should be on a 10-12 hour day length, and the plants can be grown six to ten inches from the light, depending on the strength of the light. Poor pitcher formation is usually a sign of not enough light.
Water & Humidity: Water frequently with distilled, reverse osmosis, or rainwater. Do not let the pots sit in water for long periods. You can water from the bottom, fill trays with water, and let the plant dry out for a few days before watering again. Be careful not to dry the plants out completely. Watering overhead occasionally is also beneficial for the plants. Ultra highland Nepenthes appreciate humidity of at least 70%. Any added humidity will be enjoyed by your plant! This hybrid will do best with high humidity. Too little humidity is the second most likely cause of poor pitcher formation.
Temperature: Daytime temperatures should be in the 68-75, with a 10-15 degree drop in night temperatures. Never expose your plants to temperatures below 40 degrees or above 90 degrees, as this can damage or kill them. Nepenthes do best indoors and should not be grown outdoors in most areas unless you have very mild temperatures.
Dormancy: Nepenthes do not have a dormancy as they are tropical plants, but they can slow down growth in winter when photo periods shorten.
Fertilizer: Apply diluted Maxsea fertilizer once or twice a month to the leaves and inside the pitchers. Slow-release osmocote pellets can be added to the pitchers along with a bit of distilled water. Small pitchers may burn back upon feeding, but this will still greatly benefit the plant with nutrients. Small insects can also be fed to pitchers.
Soil & Repotting: Nepenthes should be grown in a mix of long-fibered New Zealand sphagnum moss, orchid bark, pumice, and perlite. We have all of our custom Nepenthes soil blends available to add to your order, but you do not need to repot your plant for at least a year after receiving it from us. Nepenthes appreciate frequent repotting every three years and only move to a slightly bigger pot.
