Troubleshooting
Hansa Rose problems — and how to fix them
Hansa Rose (Rosa 'Hansa') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Suckering spread
On its own roots Hansa suckers freely and can colonise an area. Remove unwanted suckers or site it where its spreading habit is welcome, such as a hedge.
Lime-induced chlorosis
Yellowing leaves with green veins on chalky or over-fed soils. Avoid lime and high-pH conditions; mulch with acidic organic matter and ease off feeding.
Floppy blooms in rain
The full double flowers can ball or droop after heavy rain. Plant in an open sunny spot so blooms dry quickly and weak stems are minimised.
Rose aphids on new shoots
Soft spring growth attracts aphids. Usually controlled by predators on this robust plant; hose off heavy infestations rather than spraying.
