Geraniums , both tender geraniums ( Pelargoniums ) and hardy geraniums , can be comparatively well-to-do and trouble - free plants to grow .
The hardy types especially can be bully low - maintenance plants for a garden .
However , there are some jobs that it is important not to neglect , and pruning is one of them .
According toexpert Horticulturist Colin Skelly : “ many hardy geranium , peculiarly taller or flop - prone coinage and cultivars , will look better later on in the time of year if give a ‘ Chelsea chop ’ – so - called because it is typically carried out in May around the bloom show metre .
“ This will ascertain a healthy industrial plant and flush into late summertime . ”
That being say , how you snip geranium will reckon on which type you are grow , and , if growing attendant case , how you plan to winter them .
Here are the introductory principle to follow :
Pruning Pelargonium (Tender Geraniums)
When you should prune Pelargoniums depend mostly on how you have ( or project to ) overwinter them .
Remember , these are plant life which can not subsist the winter outdoors in our mood .
Pelargoniums can be keep for more than one year , if you do not bid to dispose of them at the death of the season by :
The pruning fourth dimension and the extent to which the plants are bring down back will depend on which of these choice you have chosen .
If you decide , at the ending of the growing season , that you would care to keep your genus Pelargonium in a dormant state in pots , then you should cut back the works to around 10 centimetre above the surface of the growing medium in autumn , when you fetch them into a icing - devoid emplacement .
You might also cut in fall if you plan on maintain your plants in pot in active growth .
transfer any yellowing or browning leaves and any sprawling growth , and , if the plant count a morsel leggy , you’re able to also regard cutting back halt by around one - third to one - one-half .
However , this may not be necessary and you may hold back until spring .
Pelargonium which are winter as unembellished - antecedent plants should typically be cut back to 10 centimeter in spring .
Regardless of which option you have chosen , with most Pelargonium it is also a good estimate to nip off the growing tips after impudent raw growth come forth in spring .
This simply imply nipping or snipping off the top 1 - 2 cm from all the stems just above a foliage node .
Where the tips have been pinched off , this will advance unexampled fork to occur , which leads to a bushier and fuller works .
Pruning Hardy Geraniums
Hardy geranium are low maintenance and do n’t always need much pruning at all .
But it can be a good melodic theme to keep them levelheaded and forbid straggly or woody plants by pruning back by around one - third after they have polish off anthesis , as Gary Carroll , proprietor of Cranesbill Nursery , explain :
“ Most hardy geranium will gain from being cut intemperately back halfway through the season .
“ They will then bounce back with bracing foliage and , normally , a second blush of flowers .
“ The plant will lean to give you a hint when to do this , as it will start out to look a bit commonplace , and the bloom might diminish . ”
If a plant is not looking as honest , you’re able to heavily dress back to just above the undercoat to give your plant a new term of a contract of life .
However , be cognizant that not every geranium variety can cope with punishing pruning .
“ The two main types that are a bit unlike as regards turn off back , are theG.xcantabrigiensesandmacrorrhizums , ” says Gary .
“ These can be turn out back , but they have thick stems from which the foliage sprouts , which you should n’t write out into , as these stems shape the [ independent ] structure of the plant life . ”
