Watch the Feeding 



With the weatlar stayiiitr warm it will be necessai^' 

 to be very careful with tlie feeding, and see that it is 

 applied at the proper time, and then withheld when it 

 should be. As soon as a crop is well cut off the plants 

 should be allowed to dry out just a trifle, being careful 

 of course not to carry it too far. As soon as the plants 

 are dry enough they can be watered well, being careful 

 to make sure that the water penetrates through the soil, 

 leaving no dry spots anywhere. To make this sure it 

 may be necessary to water twice over the bench fronts 

 where the plants will naturally be drier than anywhere 

 else. Then if they are not showing any breaks to speak 

 of they can be allowed to dry out fairly good again, after 

 which they will break quite freely as a rule. As soon 

 as the plants have quite a number of breaks all over 

 they can be given a little liquid manure or bonemeal 

 and as soon as the breaks lengthen out a little tliey 

 should receive a light mulching if they need it. The 

 surface of the benches will tell this. If the mulch that 

 has been put on is pretty well gone and the soil m the 

 benches lies exposed to the sun and air, it ie time to 

 apply more. If, however, there is plenty of rough ma- 

 terial on the benches to keep the water from washing 

 around when w'atering then it will not be necessary to 

 apply any more manure, depending on the liquid to 

 furnish all the necessary plant food, using plenty of 

 bonemeal to go with it. However, it may not always 

 be advisable to use too much liquid, especially if the 

 plants show signs of getting soft If this happens it 

 will be well to run the houses a shade cooler, and keep 

 the liquid away until the plants show signs of starving. 

 This can be seen on the new growth which will lierome 

 somewhat stunted in appearance. 



The Coal Bins 



With the warm sunny weather all along, growers are 

 apt to neglect to order or have on hand sufficient coal. 

 This is bad management for the warm weather will no 

 doubt be followed by a severe cold snap, and coal will 

 burn rapidly then. Keep the ooal coming as fast as 



it is used so that in case of early snow there will be 

 no heating problem to bother about. Considerable coal 

 can be saved by keeping the boilers clean all the time. 

 See to this as the boilers should be brushed every other 

 night. There are no especial brushes required for this ; 

 a piece of old burlap on a stick will generally answer 

 the purpose and nearly all the boilers built now can be 

 cleaned while the fire is going full blast, as most of 

 them are arranged to op»n one flue or part .it a time. 



Storing Manure 



Manure for mulcliing which has to be kept outside 

 in the weather will leach out a good deal, and this will 

 mean loss. There is no way to prevent this except to 

 have one of the sod heaps only three and a half feet 

 high, and then keep the manure pile on top of this. 

 Any liquid that may drain through the manure will be 

 quickly absorbed by the sod in the heap and there will 

 be little waste. Needless to say the heap should be cov- 

 ered with straw or hay or leaves or anything to keep 

 it from freezing in the winter so that it will be ready 

 to use at any time. 



Soot 



The prices that roses have been bringing the last 

 few weeks will enable gTOwers everywhere to indulge in 

 little luxuries every now and then. Soot may be consid- 

 ered a luxury for commercial growers, but it will cer- 

 tainly put additional color into the roses if applied at 

 the proper time. It can also be added to the liquid 

 manure but we prefer to apply it directly to the benches, 

 using only enough to slightly blacken the surface of 

 the soil. After this a little more can be applied when- 

 ever it is needed. It is best applied when the Inids are 

 about to show color. It is quite strong and may damage 

 the foliage somewhat if too much of it is applied all 

 at once. Never apply it at the same time with bone- 

 meal, or to benches that have been limed recently. The 

 lime in the bonemeal or in the benches liberates a large 

 portion of the ammonia in the soot all at once and this 

 is waste, even if there is no harm done to the plants 

 and flowers.
