 PiNCYi,EA\ED CALADinib — As soou as the plants 

 begin to lose their leaves in the fall water should 

 gradually be withheld until the leaves are all gone 

 The pots should then be removed to a position under a 

 bench and laid on their sides or taken from the soil 

 and placed m sand During the resting period they 

 should not be subjected to a lower temperature thin C0° 

 F and kept neither too wet nor too dry Al out the I e 

 ginning of March the tubers should he started f ji the 

 earliest hatch to be grown in pots. Arrange the tubers 

 in their sizes. an<l keep each size by itself. The largest 

 sized tubn-s will start quickest, and it is desirable to be- 

 gin with ili.sc t(ir pot plants. Start them in chopped 

 m.is- in lMi\es. rhe tubersmay be arranged pretty close 

 togithir in the bus, and merely covered over with the 



CALADIUM 207 



moss to the depth of about an inch. The new roots are 

 made from the top part of the tuber, so it is important 

 that this part should be covered to encourage the roots. 

 For starting, a heat varying between 70° and 85° will 

 suffice. As soon as a healthy lot of roots make their 

 appearance, the plants sh"iili| Im- iH.tt.-d, nsii,L' as small 

 sized pots as possible. 'I'h. -,,il imi iin- i.i 1 1 1- should

this occasion be a littli- sin,nj,i' ; l: i , . ,i jim-itioh near 

 the glass, and shade from strung sunshine. New forms 

 are raised from seed, this operation being an exceed- 

 ingly easy one with the Caladium, as they cross-fertilize 

 very readily. The flowers, unlike those of the Anthu- 

 rium, are moncecious, the females ripening first. To 

 pollinate them, part of the spathe must be cut away. 

 (seedlings at first have the foliage green, and it is not 

 until the fifth or sixth leaf has been developed that 

 they show their gaudy colorings. Propagation of the 

 kinds is effected by dividing the old tubers, the cut sur- 

 faces of which should be well dusted with powdered 

 charcoal to prevent decay. As bedding plants, the fancy- 

 leaved Caladiums are gradually getting more popular. 

 To have them at their best for this purpose, the ground 

 should be worked for some time previous to planting 

 out, with a goodly quantity of bone meal incorporated 

 with the soil. The tubers are best put out in a dormant 

 state, as then they make very rapid progress, and eventu- 

 ally make finer plants than when they are first started 

 in the greenhouse, as by this system they are too apt to 

 sustain a check in the hardening-off process, and lose 

 their leaves. The fine, highly colored kinds are not so 

 well suited for outdoor work as those having green pre- 

 dominating in the foliage, but some of the kinds, such 

 as Dr. Lindley and Rosini, do remarkably well. Fre- 

 quent watering with manure water is absolutely neces- 

 sar\ to the development of the foliage both outdoors
