How do you care for salvia plants in winter ?

Well , salvia coinage and their derivative cultivar set out all the elbow room from tiptop - intrepid varieties rated to H7 all the way of life down to H2 sort that may not live temperatures even tight to 0 ° C .

“ The only thing that permit the salvia down is that they are not reliably hardy across most of the UK , ” shares Lachlan Rae , a Garden Designer .

“ Still , I would n’t be without them . I think they are fantastic and there are so many brilliant late - blossom smorgasbord . ”

So the dubiousness for UK gardener really is , should you care for your Salvia industrial plant in winter ?

If your variety has a hardiness paygrade of H5 or above , you and your salvia works are all set for wintertime , then you ’ll need to do nothing except protect the industrial plant from northern photograph .

But if your salvia variety is rat H4 or low , you will need to take progressively more winter precaution of the works the less hardy it is , and even more so if you live in the country ’s colder regions .

“ think of , all big folio Salvias are frost tender , ” admonish salvia expert Lyndi Garnett , Coordinator of the Victorian Salvia Study Group .

“ In cold area , keep these varieties in a glasshouse away from low temperature and frost . ”

Depending on your indigence , you’re able to protect your salvia plants during winter by take away these measures :

My four key measures are explained in more depth below .

1) Bring Potted Plants Indoors

Before the anticipated first rime of the season , bring in your pot salvia indoors or , better yet , put it in a greenhouse if you have one .

The indoor temperature should stay on above the minimum necessary for the variety in question , so before you put a plant life in a frigid shed , find out on its hardiness paygrade to see if it will survive the anticipated temperature low in the shed .

The huge majority of salvia diversity should have several hours of lineal sun per day , so site the container accordingly .

“ As well as protect Salvias over the wintertime , I take cuttings semi - hardwood cuttings in recent summer to ensure that I have backups should the wintertime weather do its worst , ” shares Horticultural Consultant Colin Skelly .

“ you’re able to also separate clumping Salvias to keep under cover to ensure some small pots of ‘ insurance ’ plants . ”

2) Protect From Wind & Rain

Evergreen sage that are in the open ground and which are fearless enough to survive the winter should be protected from north winds , so sort them appropriately .

They should not stay in the cold , plastered ground for a draw out period or even for a few days in winter .

Therefore , if you have a thunderstorm , sleet , or snowfall , be certain to check on the basis .

If the soil is waterlogged , you will need to enfeeble off the wet if you want to keep your plant .

It would be wise pre - emptively to encompass the ground with a flat solid of plastic or tarp if you anticipate wet atmospheric condition in the winter .

3) Lay Mulch

Deciduous salvia that are in open land and which are hardy enough to subsist the winter should be allow to retain their withered foliage as , to some extent , this will shield the plant from icing and stale .

Foliage can be pruned after the last Robert Lee Frost of spring .

Before the first rime of autumn or winter , enforce a 6 - 8 cm layer of mulch made of pine phonograph needle and barque , or constitutional compost .

Mulch will protect the flora from Robert Lee Frost and wetness .

4) Use A Horticultural Fleece

Before you look for severe cold weather , protect open - ground salvia with a horticultural wool .

The horticultural fleece should cover the main stem and the crown rather than the entire plant .

If you embrace much of the foliage ( as in the image shown above ) think back to remove the fleece for several hour during the tallness of the day and then replace it in the late good afternoon .
