108 PIOTOBIAL PRAOTIOAL FRUIT GROWING. 



morning papers are good, and may be fol'/owed. Beyond this, it may be 

 suggested that provision should be made for ventilators on each side of all 

 span-roof structures, and in doubtful weather those on the lee side should 

 be opened a little, while those on the windward side are kept shat. Further, 

 the sternest resolution must be come to, and not only come to but adhered 

 to, for early morning ventilation. 



(4) Pruning. — Circumstances must rule to some extent in this matter, 

 and one very important consideration is the form of the vinery. In the 

 long, low structures usually associated with the name of ground vinery, the 

 best plan — indeed, the only practicable one — is to plant the Vine in such a 

 way that the rod can run along in a horizontal position under the light, and 

 fruiting laterals be trained on it at right angles. I have seen a Vine planted 

 in the centre of such a structure, shortened hard in the winter, two buds 

 selected, and shoots taken from them in opposite directions towards the 

 ends of the house. Another plan is to put a Vine in at one end, and let the

rod run towards the other end ; or put one in at each end, and let them 

 meet in the middle. It is not very material which plan is adopted, so long 

 as this point is kept in mind: The rod must be at least 1 foot from the 

 glass, and the laterals shall not be nearer to each other on opposite sides of 

 the rod tlian 9 inches, or on the same side of the rod than 18 inches. It 

 may, liowever, happen to be necessary to keep the fruiting shoots all on one 

 side of the rod, in which case they may be 1 foot apart. Particulars of 

 spur pruning, which is the system that ought to be adopted, have been 

 given in previous pages. Careful attention to stopping is necessary. 

 Without it, the shoots may easily become so tangled a mass that the fruit 

 has no chance. 



There is one consideration which the person who wants to indulge in a, 

 ground vinery must always keep in view, and it is this : Owing to the very 

 limited room, routine work, particularly tying tlie shoots and thinning the 

 bunches, has to be carried on under difficulties ; therefore have a structure 

 made in sections that can be opened so easily and completely that any part 

 of the Vine may be got at without trouble. Really, every section ought to 

 open freely. The figures given herewith show both a lean-to and a span.
