sliailc, though the plant illustrated 

 li,,l(is its foliage and color well and is 

 .rrowing in the full sun. 



The plant of Phu'nix C'aiuirionsis is 

 u(,t growing at Los Angeles, but a few 

 miles distant, at Pasadena. As will be 

 lilted, the plant is finely developed, 

 li. viug held its fronds for a number of 

 V ars. It is a quick growing, robust 

 p;lra, needing ample room for its full 

 ,1 velopment. 



Khapis flabelliformis is another beau- 

 t tul palm when well grown, and one 

 t i;it is not as much grown as it de- 

 - rves to be. 



LILY FOLIAGE BROWN AT TIPS. 



Can you tell us what makes the ends 

 . :' the leaves on lily plants turn brown? 



K. B. F. C. 



There are two or three possible 

 :iuses for the foliage on your lilies 

 1 irning brown at the tips. If they are 

 landing too close together and are 

 Imsed quite freely, an excess of mois- 

 ture may start it. Overdoses of stim- 

 ulants, particularly those of a chemical 

 ii;iture, may produce a like result. 

 Strong fumigations are another cause. 

 None of these may meet your case, but 

 if you can give the plants a night tem- 

 perature of 60 degrees, water freely 

 mid care for them well the trouble 

 should practically disapi>ear, although 

 n.casional plants may continue to de- 

 \i'lop it, especially if they are kept 

 !iio wet at the root. C. "W. 



TREATMENT OF CANDYTUFT. 



1 have a batch of candvtuft just, 

 iiiicly out of the soil. At what time 

 '.111 1 expect them to bloom, and at 

 what temperature shall I keep them? 

 Which would be better, to transplant 

 into flats or into pots before jaitting 

 ilii'ni in the bench? How ituu-li s[)ace 

 ^viU each plant require in the bench? 



\V. 1). 11. 



<Jandytuft is in great (leiiiaiid at 



^liTiiorial dav. "S'our plants ar(> just 



' little late 'for that date, but it will

''"t off singly. When they are nicely 



-tablished ;nid before they become too 



iifh pofboiind, plant them out in beds 



hciiches in rows twelve inches apart, 



liiwiiig six ()!■ seven inches between 





the plants. The soil must be well en- 

 riched and such as you would use for 

 carnations or chrysanthemums. Give 

 them a temperature of 4") degrees at 

 night. Kaise this to 48 or .10 degrees 

 as they advance, running them a trifle 

 cooler as the flowers open. C. \V. 



ADIANTUMS. 



Where adiantums have been resting 

 for a few weeks they can now be over- 

 hauled and, where necessary, repotted. 

 Ijarge sized plants will carry for sev- 

 eral years in the same pots if occasion 

 ally fed with li(juid manure, but smaller 

 sizes are liable to become starved if 

 not shifted, and furthermore there is 

 more or less danger of their drying out 

 and losing much of their foliage. One 

 severe drying off is generally sufficient 

 to ruin the appearance of an adiantum, 

 and this is most liable to occur with 

 the smaller plants. Large plants can 

 l)e divided, but these divided portions 

 do not give as satisfactory returns as 

 younger plants potted on. While the 

 adiantums take kindly to soil contain- 

 ing considerable leaf-mold, and this is 



Phoenix Canariensis. 



Rhapis Flabelliformis. 



particularly good for young stock, 

 larger plants want something heavier, 

 ami good pasture loam, with some 

 thoroughly decomposed manure added 

 and a good dash of sand, will grow ex- 

 cellent plants. Bone and chemical fer- 

 tilizers are better not used in the soil, 

 although a little Clay "s or Bon Arbor 

 in the water during the growing sea- 

 son is excellent for them. A. cuneatum, 

 while still the s[)ecies mostly grown, is 

 not equal to A. Croweanum commer- 

 cially. The growths of the latter are 

 tougher and keep much better out of 

 water. 



PRIMULA OBCONICA. 



With conditions favorable, how long 

 should Primula obconica continue flow- 

 ering? We have some that began flow 

 ering about January lO. Wo should 

 like to hold some of thetn until Easter 

 if this can be successfully done. They 

 are in 5-inch and 6-inch pots and are 

 well flowered. We are giving them 



Jubaea Spectabilis. 



li(iuid cow nuinure every week or ten 

 days. Tiiey have a nice head of flowers, 

 with si)ikes in all stages of growth. 



T. S. M. 



This primrose is persistent-flowering 

 and will easily last until Kaster in a 

 cool house. In fact, it will bloom until 

 .Funo if wanted. Keep the fade<l flow 

 crs and seeds removed and continue to 

 feed with cow manure as vou are doing?

EFFECT OF SULPHUR IN WATER. 



We are in need of information re- 

 garding the use of water from a sui- 

 jdiur water well, for irrigation. What 

 effect will it have on flowering plants, 

 such as sweet peas and asters, and 

 what effect on the soil.' We thought 

 that perhajjs some of the readers of The 

 Review might have had experience 

 along this line. We have a sulphur 

 water well which will furnish all the 

 supply we shall need and there is nu 

 other water available. D. R. W. 



So far as th(^ sulphur water is con 

 cerned, whether it will injure plants 

 will depend upon the amount of sul 

 phur and the form in which it is found. 

 A small amount of sulphur would not 

 he injurious and might be helpful, as it 

 is a splendid fungicide. The trouble 

 is more likely to come from various 

 alkalis which ar(^ often associated with 

 the sulphur in the water, but, as they 

 are odorless, their presence is not sus 

 l)ected. Jf they are present in consid 

 erable quantities the water would not 

 lie fit for greenhouse use. The best 

 way to determine whether or not it 

 can be used with safety is to try it for 

 watering a few plants and at the same 

 time water the same numl)er of other 

 plants with water which is known to 

 be free from sulphur and alkalis of all 

 kinds.
