I have some lovely rose bushes in the garden,here when i moved contained by . They have lots and lots of flowers in adjectives shapes and sizes . The problem i they dont seem to open they get hold of to a point and then seem to rot unopened turn brown and the die. Any concept? The plant itsself looks healthy enough but the buds give the impression of being to be having problems.
Answers:    Rain has rotted the outer leaves and that stops the inner bit from passage.Cold nights can do the same.Immeadiately cut them adjectives off and a new set will grow next.If it rains again the buds will open as the space heater weather will evaporate the wet quickly and no rot will form on outside
