    Default Culture Questions Regarding Cattleya Violacea

    A few months ago I acquired a bare root Cattleya violacea with mostly dead roots. I have mounted the plant with a bit a sphagnum moss to keep the plant slightly moist. Now I have noticed that the plant is starting to grow a new growth, but still has no roots.

    I have reviewed several websites and could not find specific information regarding the growth cycle for this plant. My questions are: (1) does Cattleya violacea normally start new growth this time of year, and (2) when does this plant typically grow roots?

    I have not grown this orchid but was able to find some information. As a rule these take a Winter rest during which watering is reduced but the plant should not dry out excessively or remain dry for long. New growth normally begins in the Spring. I would try giving the plant moderate light conditions and intermediate temperatures. I would up the watering a little if root development begins. The plant is beautiful and I wish you the best.

    The roots will sprout from the base of the new growth when it is nearly fully developed. Because the plant has no roots left on the older pseudobulbs it may try and put out new roots earlier when the growth is only about 4 to 5 inches tall. The old growths will certainly not produce any new roots, so you must ensure that the new roots stay happy when they emerge. This particular species is more temperature sensitive than most cattleyas. It comes from lowland rain forests and mostly grows high up on large trees close to rivers that flood the surrounding areas for several months of the year. As a result of this it likes a very warm, humid and bright environment with good air movement and drainage. In its natural environment it doesn't get a cooler rest period, it simply rains a bit less during a couple of months but you can't really call it a dry season either. It should be kept warm all year round with just a bit less water during winter. If you can't provide hot house temperatures during the colder months, it's best to reduce the watering and let the bulbs shrivel a little bit than to keep it moist and cool. Mounting the plant is a good idea as they tend to rot easily if kept too wet or cool when potted.
