QUERIES. 



On planting Rhododendrons. — About two years ago I planted a'large bordci 

 with Rhododendrons, formed of a compost which I considered very suitable, but 

 they languished, and the leaves turned yellow. 1 have now prepared an entirely 

 new compost, thus: — one-third heath-mould from a dry stony moor, one- third 

 line light loam from a rich pasture, and the remainder equal parts of river sand 

 and vegetable mould, well prepared for at least half a year ; and as the above 

 failure may have arisen from latent moisture, I propose placing in the bottom a 

 stratum about six inches deep of broken brickbats and river sand, covered with 

 twigs of larch or other wood ; but I should esteem it a great favour to have the 

 benefit of your opinion or suggestions in your very next Number. 



The situation of the border is partially shaded by trees from the meridian and 

 afternoon sun, and therefore one that I considered eligible.

On Pruning Standard Rose Trees. — A few directions in an early Number 

 of your Cabinet on a successful mode of pruning the standard Roses will much 

 oblige a young gardener and constant subscriber.

[Every shoot of last year's wood that remains must be shortened to three or 

 four buds. If not pruned in this (apparently) severe manner the head will soon 

 become straggling, the shoots weakly, and flowers small. Only as many 

 shortened shoots must be left for blooming as will keep the head properly siqi- 

 plied without crowding, bearing in mind that each of the three or lour buds left 

 will produce a shoot. Attention must also be paid to have the head equally ba- 

 lanced. Where the head of a standard has been improperly treated, and in con- 

 sequence the shoots of several years, now old wood, are too extended, then cut 

 the shoots of old wood back to within a few inches of their origin, and so form 

 a new head. The portion of old wood retained will push shoots, which generally 

 will bloom the following season ; and if, in a seldom case, they should not, they 

 will not fail to do so every subsequent one if properly treated. ^Judicious severe 

 pruning is essential to secure satisfactory success in blooming the Rose, and 

 annually have a dressing of manure on the surface of the bed to be washed in 

 by the rains in winter and spring. — Conductor.] 



On Arnott's Stove, &c. — Will any of your correspondents favour your readers 

 by informing us how the Amott stove answers fur greenhouses ; also, what size 

 a tank should be to hold water sufficient to give out heat for ten hours in a mo- 

 derately sized gveenhonse. 



I think Geraniums, if kept dry, and not excited into growth in winter, will bear 

 a lower temperature than is generally supposed. Last night the thermometer 

 out doors stood at sixteen degrees below freezing at ten a.m., and a small Arnott- 

 stove, which I use in my greenhouse, must have gone out eaily in the night, for 

 the coke, &c. were unconsumed when I examined it this morning. At half-past 

 seven this morning I found the thermometer in the house, which is perfectly well
