THE FLOKAL WORLD AND GARDEN GUIDE.

efforts must be made to keep down green- 

 fly and thrips. Many of the less tender 

 things may be removed to cold pits, to 

 increase the room for other things that 

 want continued protection, to make fine 

 plants. Young stuff from the propagating- 

 house should be potted as fast as rooted, 

 and kept close till started afresh, and then 

 be gradually inured to air and light, so as 

 to bo strong by the middle of May. All 

 tropical plants required for summer bloom- 

 ing in the house should be got on without 

 delay, and a quick growth promoted, so as 

 to allow them as long a season as possible 

 for blooming, and ripening their buds for 

 next season. Average temperature this 

 month, 55" by night, 60' to 65' by day. 

 Where desirable, the house may be shut up 

 with sun-heat, to render fire unnecessary. 



Stove. — Many choice subjects may 

 now be propagated, such as justicias, 

 euphorbias, erauthemums, etc.; use for all 

 such a brisk moist heat. Recently potted 

 specimens will now be growing freely, and 

 must have plenty of water, and crowding 

 must be avoided. On fine days the ther- 

 mometer may go up to 90°, which must be 

 the maximum ; to prevent any further rise, 

 give air. Orchids will require frequent 

 attention, and those in bloom to be kept 

 tolerably cool, to prolong their beauty, 



Water must be used abundantly, both to 

 keep roots moist and to fill the atmosphere 

 with vapour. 



Vinery. — Vines in bloom must be kept 

 warm and dry ; air may be given, but it 

 must be with care, so as to neither admit 

 damp nor cause any check by lowering the 

 temperature. Brush the hand over the 

 bloom lightly at midday, to assist insetting 

 the fruit. In forward houses set about 

 thinning the bunches as soon as they are 

 the size of peas. 



Pineby. — If there is any lack of water 

 now, red spider will make sad havoc. 

 Keep up a good growing temperature, and 

 pay special attention to plants showin" - 

 fruit ; young stock, 65° to 75' ; fruiting 

 plants, 70' to 85\ 



Pits and Frames. — As auriculas 

 show colour, remove them to a shady and 

 sheltered situation under hand-glasses 

 placed upon bricks, and on frosty nights 

 put mats over them. Remove carnations 

 and picotees from the frames. If beddino- 

 stock is still in request, put in more cut- 

 tings ; a heat of DO 3 may be used now if 

 the cuttings are of stout young wood. 

 China roses may be propagated now by 

 taking off young shoots close to the old 

 wood when four inches long, and plunging 

 in a moderate heat. 



TO CORRESPONDENTS. 



A Preventive or Onion Grub. — For 

 a number of years past I have been 

 sadly tormented by the onion grub ; in 

 some seasons they destroyed my whole 

 crop, but the last two seasons I have 

 been quite free from the pest by using 

 the following mixture : — To a barrowful 

 of dry sawdust mix two quarts of coal 

 tar ; mix them thoroughly, so that the 

 sawdust may be quite blackened by the 

 coal tar, and have the appearance of 

 soot. In the beginning of May I sow 

 the above quantity over four "beds 30 

 feet long by 3^ feet broad. It is not at 

 all injurious to the young onions. The 

 smell of the coal tar, I suppose, banishes 

 the onion fly, as I have had fine healthy 

 crops since using the above precaution.

Delphinium Chinense. — R.T.E. — This 

 may be had in bloom in the coming 

 autumn from seed sown at the latter 

 end of March, if they are "pushed on," 

 as gardeners call it— that is if they are 

 kept in the greenhouse till May, and 

 regularly shifted, first to thumb pots, 

 then to the next size, and so on, as fast 

 as they fill their pots with roots. Then 

 if planted out at the end of May, and 

 carefully tended as to watering, a good 

 bloom will result.
