Tuberose Plants

Tuberose plant flowering

Zone Trivandrum | Srivishnu45 added on May 29, 2018 | Answered

I planted 20 rajanigandha/tuberose bulbs 5 months ago. All of them grown well and now spikes have come out from all plants. Lots of buds are in each spike. But the buds are decaying. The buds are not opening/growing into flowers. Each bud is decaying from the spike and getting brownish and falling down . But the plant and stem of spike are healthy. What will be the reason for the decaying of buds ?

Sir checked thoroughly and found small spider nets in between buds and spikes and also found some too small spiders also. How to get rid of them?

Of the few pests and diseases that affect tuberose, most would also show signs on the leaves. Since it is only flowers that are affected, 3 possibilities remain. One is a fungus, Botrytis cinerea, that typically strikes when weather is wet and cool and two are insects. Thrips and spider mites are tiny - spider mites are the size of a grain of pepper might be infesting the buds where they suck the juices. Spider mites can sometimes be identified by a small spider-web appearance near the bud. Examine buds carefully for these pests and hand remove or choose an insecticide that is rated for those insects.
