WINTER PROTECTION 



79 



Some perennials have a fleshy root system (as Alkanite, Hollyhock, 

 Foxglove, Poppy, etc.)? and these are likely to decay as a result of 

 standing in water. Therefore, as in the case of tender bulbs, mound 

 the soil above them; then after it has frozen, the manure or hay can be 

 spread. 



Another class of plants which retain their leaves throughout 

 Winter — both shrubs and perennials — should be well covered 

 with dry leaves, which can be kept in place by boards laid right over 

 them. So placed, the boards will prevent water from soaking directly 

 through the leaves to the plants, and possibly heating and decaying 

 them. No moist or fresh manure should come in direct contact with 

 any perennials. 



Vines can be covered with burlap as suggested for climbing Roses . 

 If not hardy, take them down and bury them, mulching afterward. 

 However, very few vines need much attention.
