332 Mode of pruning Filbert Trees in Kent. 



be supplied always along with artificial heat, except in foggy or 

 cloudy weather, when fire is applied to promote ventilation. 



Temperature. — I should begin at 40° ; flower and stone, at 

 50°; and swell off at S5° artificial heat, always allowing 10° 

 more during sunshine. 



Insects, Sj'c. — Almost all the enemies and evils that fi:uit trees 

 are troubled with seem to rally round this devoted tree. Whilst 

 the fruit is growing, gentle fumigations of good tobacco (not 

 coarse rank refuse, or tobaccoed paper) will keep down the 

 green or black fly ; a fine dew, shed over both surfaces of every 

 leaf, twice a day, except when in flower and ripening off", by 

 means of a hand engine, or a finely perforated syringe, will 

 greatly annoy, if not eradicate, the red spider, and benefit the 

 trees. Hand-picking will be found the best and surest remedy 

 for the light green caterpillar, that rolls itself in the leaves, and 

 syringing the trees with pure soft water every evening in hot 

 weather, after the fruit is gathered, and the lights taken off": 

 this will prevent, in a great measure, the harbouring of insect 

 larvae about the buds and in the crevices of the wood ; and will 

 aid the healthy ripening of the fruitful twigs for the ensuing 

 season. The leaders of morellos in pots must be stopped, as 

 directed for peaches, allowing only the buds that are near the 

 base to break, and remain entire, to produce fruit next season.

Art. VI. On the Method of pruning Filbert Trees in Kent. 

 By John Machray, Gardener at East Sutton Park. 



In compliance with your request, I now attempt to send you a 

 description of the method of pruning filbert trees in this quarter ; 

 and, though I have to regret that my short stay in Kent has not 

 enabled me to see moi'e of it, yet I trust that in what I advance 

 I shall be sufficiently understood by my brethren to enable 

 them to draw their own conclusions. 



I am aware that a difference of opinion exists among gar- 

 deners, as to the best mode of cultivating the filbert ; some main- 

 taining that the trees ought to be left altogether to nature, as, 

 indeed, they are in the Horticultural Garden at Chiswick; and 

 others (among whom are the cultivators in Kent) thinking that 

 they should be pruned. When this is intended, the bushes of fil- 

 berts are generally planted along with fruit trees (apples, plums, 

 or cherries, and sometimes hops); the filberts being placed 12 ft. 

 apart, and the apples 25 or 30 feet. The mode of pruning is 

 something similar to that of pruning a gooseberry bush ; keeping 

 the filberts open in the heart, and as much under hand as 

 possible. They are never allowed to get above 4 ft. or 4 ft. 6 in.
