The rose tree that I was referring to is my hot orange miniature rose.
What causes a rose bud to split and form twin blooms?
I kept asking myself this question for days. Since I am not a plant botanist, my best attempt is by visiting few relevant websites to uncover the science behind twin blooms. I found out there are few causes to such occurrence:
- A random mutation can occur during bud formation process. Random mutation can be triggered by sudden change of weather; hence the randomness. Effect of fertilizer or change in its dosage can also trigger a mutation.
- Some varieties of roses are more prone to genetic mutation as compared to others.
- Damage can also occur during bud formation process, caused by herbicide or insecticide. However, I ruled out this possibility as my insecticide spraying routine hasn’t changed since last month. It wasn’t the frequency of spraying or the concentration of the solution either.
- A mutation can be also caused by a disease, spread by mites or insects that causes the plant to produce excessive growth or distortion.
My garden has been receiving plenty of rain since early of the month. The downpours usually started at about 2 pm or 3 pm every day when the day’s heat was still at its peak. Last month, the downpours mostly occurred very late in the evening.
