Pruning encourages new growth and thickens up the foliage of your shrubs. It also promotes flowering whilst giving your shrubs great shape.
It is important to know when each species is due to flower, otherwise you might be cutting off the branches preparing to set bud for flowering. Once Spring arrives, & preferably before the days get too hot, give all your shrubs a good prune.

This guarantees that you don’t put too much stress on the plant all at once. Also leaving a sufficient amount of leaves on the plant, supports the plant to breath & photosynthesize.
Cut the stem/branches just above a node & once the plant starts to shoot then you know it is happy. It is at this point, should you need to reduce the size of the plant further, that you can prune another third off and so on until you reach your desired size.
Fertilising (where required) and definitely mulching the plant, will support it whilst it is recovering. Regular water will ensure fresh new growth in no time at all.
Ornamental Grasses can be cleaned up too by cutting them back to 5cm above ground level. As you can see in the images below, it looks pretty drastic but they will shoot and look fresh and lovely before you know it.



Splitting up your ornamental grasses is so easy and allows you to plant them into other areas of your garden, saving you money.
Once you have dug the plant out of the ground it will be easy to see the individual plants that can be divided by either cutting or prying the plants apart at the root ball. Plant divided plants quickly to ensure they don’t dry out and water in well once planted and mulched.
You can also split up Agapanthus, Hippeastrum, Dietes, Dianella, Liriope and Pennisetum, to name a few.
