my rose flowers are smaller in size what should i do to get bigger size flowers it is a semi in-door type plan

Question

at first i got big flowers now flower size is getting rreduced why

Answer 1

When the terminal (top) bud is removed from any plant, secondary buds (side of stem) are encouraged to grow and are usually smaller in size than the first. If you want larger roses, remove all but one on each side branch.

Answer 2

perhaps you might wanna fertilize the soil as it might have got weak through out the many plantation times....;)

i have no idea about farming...but that sounds good to me...
