Newbie to roses - some basic questions!
HI, i am a COMPLETE newbie to roses. I bought a few pots last season and after they developed serious mildew and black spots, abandoned them for growing other things.
Yesterday, I saw 3 pretty pots on sale and bought them to give them another go. They obviously just came out of the nursery as they were perfect - not a spot on their leaves, little buds waiting to bloom.
Ive repotted them now and put in some osmocote as feed, put them in a semi sunny spot. Now, i anticipate the same problems ahead. Should I start spraying them with insecticidal soap/neem to prevent the mildew and spots now already as a prevention, or should I wait till the problems hit?
I know these are very basic questions compared to the ones that are usually posted here! but hopefully someone can help get me started. THANKS!
