Perennials can be very forgiving when it comes to prunnng!
Dead Heading
Dead heading is the best way to get repeat flowers from your perennials!
Simple snip off all the dead flowers and wait for new ones to pop up!
Add some slow release fertiliser to speed things along.
Just be careful not to cut back in winter as they can get frost bite.
Cut Back
Herbaceous perennials go dormant/semi-dormant over the cold seasons.
Once the flowers are finished in late autumn you simply cut off all the upper growth and dried flower stems.
Don't leave it too late as they can get frost bite in winter. This step can wait until late winter/ealry spring as it becomes warmer as good bugs reside in the woody foliage!
Tidy Up
Groundcover perennials only need some tidying up.
Similar to dead heading. Simply chop off any unruly or unwanted growth.
Just be careful not to cut back in winter as they can get frost bite
Dividing
Divide bulb perennials when they aren't flowering so they can focus on regenerating root and leaf tissue!
