- CONDUCTED BY 



Questions by our readers In line with any of tbe topics presented on tbis page will be cordially received and promptly unswend 

 by Mr. Kuzicka. Such communications sbonld Invariably be addressed to the office of HORTICULTURE. 



Fumigation 



There is iiu rea-sun why tlie phiiit.s shouhl be 

 allowed to become infested with greenfly at this time 

 of the year when it is plenty cool enough to fumigate 

 and with many nice preparations made for the purpose. 

 The same applies to spraying. To keep expenses as low 

 as possible it is best to Avatch the plants closely and 

 apply a dose of spray or fumigate as soon as the least 

 trace of insects can be seen. Do not wait until they 

 increase to large niunbers, as it will be hard work to get 

 rid of them then, for the smoke or spray will have to 

 be made quite strong to kill some of the older ones who 

 are pretty tough as a rule. Try to spray or smoke Just 

 l)efore syringing. The work should be done the last 

 thing in the evening or at night and never in the day- 

 time unless it is cloudy. In spraying, spray in the 

 morning during the winter and late in the evening 

 (luring the wann and hot months of the year. To 

 make the fumigating as effective as possible have the 

 plants plenty wet enough. Then do it on a quiet day. 

 When it is raining is an ideal time, as the houses are 

 tighter then, as all cracks and spaces between glass are 

 tilled with water. 



Tobacco Steins in the Walks 



With winter here, the houses not getting very much 

 air, growers will be thinking of tobacco stems for the 

 walks to keep the greenfly down. Personally I do not 

 like the idea of the stems either, as they make the walk 

 unnecessarily damp. Also the air in the house is not as 

 healthy to work in when charged with the odor of the 

 stems. Growers who smoke will not notice this at all 

 or if they do they will not mind very much. j\lake no 

 mistake in thinking that these stems will rid the plants 

 of greenfly for they will not. They will help prevent 

 greenfly from spreading but the houses must be clean 

 before the stems are put in. As soon as the stems get 

 stale more will have to be put in, taking the old ones 

 out before doing so. The old stems should not be 

 wasted but should be put on the manure pile as they 

 make excellent plant food when they decay and nre very- 

 good to use in the vegetable garden. 



Syringing Young Plants 



As soon as the young tattings become established in 

 the pots" they will have to be syringed. This work must 

 be done very carefully and with less pressure.than what 

 is used for" the old plaiils. Also the spray .should be 

 directed to hit the plants as the leaves are pointing and 

 should be steady, moving the nozzle from side to side. 

 No up and down motion should be used at all as this 

 will shake up the cuttings a good deal, and ruin quite 

 a few. In syringing okl ]flants in benches next to the 

 young stock care should l)e taken not to throw any 

 water from the old plants on to tlie young as this water 

 is likely to be mixed with some spidei-s and these would 

 certainly make themselves at home on the little plants. 

 Care should also be taken to syringe the plants very 

 quickly and quite early in the morning so that they 

 will have every chance to dry off before night. 



Watch Out for Worms in the Pots 



Sometimes the man a|)plying lime to the benches be- 

 fore the ashes are put on will lie a little careless and 

 not cover the soil well and some woims will work up 

 into the pots. If there are not very many it is best to 

 take the plant and knock it out of the pot, and as a rule 

 the worm can be caught right there. If there are many 

 plants affected this way then it will be necessary to 

 give them a dose of lime water which will do away with 

 most of the worms. There are worms in the soil used 

 for potting at times so it is not always a case of care- 

 less work in preparing the i)ench. These may be in egg 

 form, so thev may not be noticeable, but as soon as 

 given heat and moisture they liiitcli nuf and make a 

 nuisance of themselves. 



Watering 



With the dark days of winter here every now and 

 then, sreat care should be taken not to get the plants 

 too wet. This applies esiiecially to Beauties, and plants 

 that are cut off pretty well. If there is any spot on the 

 ])lants at all it should he picked oft" as it is almost sure 

 to spread and prove quite botheisoiiie before spring 

 .sets in. 



objectionable on either account. Yet even in this 

 materialistic twentieth century youth may i-espectfuUy 

 do homage to age and experience, and in any and every 

 era an indebtedness can be honestly acknowledged. 

 For the attention and loving care he has lavished on 

 the seeds, plants, sticks and roots 1 culled in the back 

 Mocks of western China and dapan, 1 iiwe .lacksou 

 Oawson a debt of gratitude and my apjn'eciation of liis 

 taie lacks notliing from a full knowledge of the utter 

 lutiiity of a collector's work when his spoils fall into 

 I lie hands of the indifferent or incompetent. Though he 

 may be quite unconscious of the fact, it is none the 



less true that virtually every reader of this paper also 

 owes something to tliis grand old gardener. And the 

 science of Horticulture owes him a lasting debt for his 

 labors toward its uplift. Long may Jackson T. 

 Dawson in health and strength be spared to increase 

 this debt, and to increase in number and variety the 

 plants he lo\-es so well.
