Vinca small-scale ( usual red periwinkle ) is a repeated groundcover in USDA zone 4 through 9 and an annual plant in cold regions . Although gardeners usually apply vinca as a ground cover in shady growing areas , it also create an attractive tracking plant when you use it in containers . As wintertime approaches , winterize genus Vinca plants growing in the soil by cover the leafage with a heavyset layer of mulch . The mulch will foreclose rough winter winds from drying out these recurrent plants .

Step 1

Allow the vinca to proceed to turn unprotected throughout the autumn months until late fall . Vinca will continue to thrive throughout most of the autumn conditions , include periodic Robert Frost and freezes .

Step 2

employ 3 to 4 inch of shredded mulch over the full country where vinca is growing in late fall . One grounds for not give the mulch too early in the fall season is that it invites rodent to tunnel in the mulch and they may spend the winter within the mulch . Spread the mulch evenly over the vinca , cover the foliage entirely .

Step 3

Remove the mulch the next spring when the temperature begin to moderate . Vinca will tolerate some immobilise temperature , so removing the mulch in other springiness is best for the genus Vinca .

Step 4

Cut back the vinca vines to prune them if they look overgrown . Most genus Vinca spell will benefit from cutting back to soil story every two to three years . The vinca will regrow with renewed energy after you write out it back .

Winterize Vinca?

Vinca favor at least fond spectre , although it can grow in full sunshine or full shade . Drought damages vinca , so it demand mulch and at least monthly wintertime lacrimation in long-winded and drouth - prostrate condition . It will also grow in container and indoors . The abject visibility makes it commodious to isolate . For greater auspices from frost , freeze and snow , whole underwrite the leaf in 5 to 6 column inch of slack mulch . A ready path to winterise vinca for unusual cold gingersnap in usually temperate climates is to cover vinca when the weather forecast is for freezing temperatures . Vinca generally reply with vigorous growth after being shorten back , so if it get important legal injury from freezing , prune the vines down to the earth and insure with mulch .
