out the colour in roses
it true that putting lime around your roses brings out the pink,
and aluminium sulphate brings out the blue? I've tried it and it
seems to work.
may just be incidental that you've had better roses that particular
year I know roses grown in Queenstown have far more intense
colour (and less insect pests) than roses grown in Auckland because
the environment is far more favourable down there than in Auckland
which is humid. A really cold winter can produce roses with more
such as light and temperature are likely to have more of an effect
on roses than aluminium sulphate or lime.
The higher the nitrogen
content, the faster the growth, the more washed out the flower colour.
More potassium, the better the flower size, colour and form. Regular
feeding, watering and care will enhance the quality of flowers.
