because they cannot be ]ilaiited over

 be all sorts of qualities.

SUGGESTIONS 



— .> 



Iiiliiun Harrisii. 



To li:i\e bilium Harrisii in tlower for 

 the holidays, the plants must be pushed 

 light along now. A night tenii)erature 

 of GS to 70 degrees, with a free use of 

 the hose overhead and a weekly fumiga- 

 tion to keep aphis in <dieck, is what 

 they need. Apply liquid manure twice 

 a week. While we are still (Mijoying 

 warm and summer-like weather, we 

 must not forget that in November and 

 December the liglit and solar heat are 

 greatly lessened, and the Hower buds to 

 be on time should be so that they can 

 lie ccmiited a month hence. 



Formosa Lilies. 



Formosa lilies do not all start at 

 once, as the Jlarrisii invariably do. 

 ."^ome may be a foot or more high while 

 others have not pushed through the soil. 

 The earlier ones can be given a house 

 with more heat, say (In degrees at night. 

 Their flowers will be useful in .lannary, 

 xvhen floweis are gent'raily not over- 

 abundant. Tiiese {'(uinosas grow all the 

 w.-iy from a foot to six feet high and 

 are quite a xariable tyjie. They are, or 

 li:i\c been, free from disease. Their 

 Mowers are fine and possess excellent 

 texture, renderiiiL; tiiem iileal for mar- 

 ket |iurpo>>es. The number grown will 

 he i iiiuieiisely iuci'ea^^ed this yeai', es|)e- 

 cially in view of the report of serious 

 'lauiage to ckiiis of mult illoi'ums aiul 

 Lii^a III iiini^ ill .la|iaii. 



Primulas. 



Ill order to iia\(' jilants of I'rimula 

 ■ dM-oiiica and Sinensis in nice tlower for 

 I liristmas, they sliould now have a tem- 

 |ieratiire of }^ lo ."ill degrees at night. 

 A ii\ tiling high"!- i.iii i....i.-n +i,n... ,1. 



(uishing on maiix' of the jdants. and .as 

 there is some sale for pot stock at 

 Thanksgiving, the earliest can be used 

 for that ((ccasioii. Do not crowd the 

 |ilaiits. It is a good ]il;in to (devate 

 ^luiie on inverted ]iots, ("^pecialh' the 

 larger ones. I'.e careful abiuit feeiling. 

 Aii.v strong dose will do a lot of liarm, 

 which no after care can remeily. Weak 

 cow manure water with some soof in it 

 ■ nice a week will keep the foliage that 

 healthy daik green one loves to see. 

 I'liless wanted early, the primulas can 



be kept in a well built frame for some 

 weeks longer. It is better to afford 

 them a little shad(,' during the hottest 

 part of the day, the Chinese seetioa 

 needing it more than the ohconicas and 

 Ixewensis. 



Hydrangeas. 



Any hydraiigi'a plants still in the field 

 should be potted at once. The advan- 

 tage of earlier jjotting is that the plants 

 have a (diance to pretty well fill the pots 

 with roots before winter sets in, and 

 they are thus the better fitted for forc- 

 ing. Established plants in pots and 

 tubs may now have their water supply 

 gradually reduced, in order to harden 

 nj) the wood and make it of that nutty 

 brown color which is so desirable. 

 Aleans must be t.aken to protect the 

 plants from severe frost. If still green 

 and s(d't, a lemjierature of liD to -'2 de 

 grees will blaidten the foliage and proh- 

 alily kill many of tlie flower buds. 



Rambler Roses. 



Crimson liambleis. and jiossibly some 

 of the pink varieties, which usually con- 

 tinue to grow later than the older ^•ari- 

 ety, should now be completing their 

 growths, if jiot grown, and the water 



supply should be decreased to assist in 

 hardening u|) the wood; not to the ex 

 tent of dust dryness, by any means, as 

 this would mean shriveled rather than 

 w(dl hardened woo<l. The jjlants should 

 hav<' all possible sun, ami to somewhat 

 counteract riMluced moisture at the root 

 the plants can have a spraying with the 

 hose once or twice a day. After the 

 middle of the month those with the best 

 ripened wood can be laid on their sides. 

 Soaking rains will have a tendency to 

 keep them soft and growing. It is yet, 

 somewhat early to dig up and pot field 

 grown ramblers. 



Canterbury Bells. 



The jiresent. is a suitable time to dig 

 up and ]pot a number of strong plants 

 of Canterbury bells, giving a preference 

 to the single or calycanthema (hose-iu 

 iiose) varieties. Stand the ])ots outdoors 

 ;ind leave them there until sharp frost 

 necessitates their removal under glass. 

 They should have sonu' frost before 

 forcing, which sluudd not begin before 

 Christnuis. If lifted with a good bunch 

 (d' roots, the plants will show little signs 

 of a check after potting. 



Freesias. 



It is time to ]dace the earliest batch 

 of freesias in a house kejit at 50 to 5'J 

 degrees at night, jirovided they are 

 wanted for Christnuis flowering or the 

 early jiart of .laiiuarv. He sure they are 

 well supidied with water, and when the 

 jians are weli filled with roots, use weak 

 liipiid manure once in four or five days. 

 Avoid strong doses, which will cause 

 the ends of the foliage to become 

 brown, just iis fumigaticm will do. Any 

 bulbs not yet jilaced in ])ans or flats 

 should be got in now. They will onlj' 

 dissipate their strength if allowed to 

 remain out of the soil any longer. 



POTTING GIGANTEUMS. 



When the bulbs of black stemmed gi 

 ganteums are received in October, should 

 they be jjotted and left outside for a 

 i-(uiple of months, or brought insitle at 

 once and placed under carnation benches 

 for a while.' H. AI. (J. C. 



(iigant(Mims and any other lilies, with 

 the exce|ition of candidum, should after 

 potting be jdaced under sash protection
