Suitable locations for roses in the garden
Many of the old varieties in particular are quite undemanding with regard to location.
Still, they should get no less than 3 hours of direct sunlight.
For climbing roses there is an exception here: starting from a shady spot, the rose may very quickly push up into sunnier heights.
This also applies to large shrub roses; a practical solution for very shady places is to "grow the plant on" in a container or at a more suitable location for the first 2-3 years and only then plant it out for good.
In general, roses grow better in sunny spots than in shade, but some blooms, especially red ones, quickly scorch in the summer sun.
Of course the various varieties and rose types have their own peculiarities regarding location, but going into more detail here would very quickly exceed the scope of this FAQ.
