How TO GROW VINCAS 



You can root Vincas at any time of the year when cuttings 

 that are not too soft can be had. This usually is during Fall or 

 Midwinter. Three or four eyes is all you want and these cuttings 

 don't need to consist of end tips. If you root them during Winter, 

 carry the little plants along in small pots up to April, when they 

 can be planted out in the field and perhaps pinched back a couple 

 of times. By October lift the plants, cut them back to about four 

 inches, divide the heavy ones and pot up into 3s or take the clumps 

 or plants and bring them into a coldhouse where they can be planted 

 closely in deep flats and kept moist up to January. Or the plants 

 can be potted up into 4s as they are and packed in on a bench. 



Just what you do with the field plants up to January doesn't 

 make much difference so long as you don't place them in too warm 

 a house or let them suffer for want of water. A period of rest does 

 them good. One of the most successful men I know brings his 

 plants, after they are cut back, into a 'Mum house and plants them 

 closely on a solid bed. By January they are divided into clumps 

 just large enough to go into 3j^-in. pots. A rich, well-manured soil 

 is used and, by the way, old Rose bench soil or such as was. used for
