rows occurring alternately. In July all the plants of the thickly strawberry^ it is generally considered, will not force the year 



after like fruit trees, but must be rested by plunging in the 



an 



crop of peas or potatoes ; and these, having the roots well pre- open ground for one or two years, pinching off all blossoms 

 served, always afford an abundant crop of fruit in the following as they appear. Williams states that " the scarlet strawherry^

any of the roots ruptured. As each plant becomes detached 

 from the surrounding soil, the ground is closed around it, and 



it remams till it is wanted, but it should be placed in its pot as gan observes, without limiting his observations to any one sort, 

 early as the middle of February, if it be not sooner removed. In that " after the fruit has been gathered from the plants, the 

 potting 5^raw6erry plants, Mr. Knight always employs soil of the pots should be plunged in a shady border, giving them a good 



richest quahty and very finely reduced, and a good deal of water, 

 holding manure in solution, is employed to occasion the newly 

 introduced soil to occupy all space previously vacant in the pots. 

 The plants are then in a state to be subjected immediately to 

 artificial heat. 



Time of beginning to force. — If the fruit be wanted very 

 early, the plants are put into hot-beds or pits in October, but 

 the crops from strawberries so forced Nicol thinks hardly worth 

 the trouble. Abercrombie says *' begin to force strawberries 

 about nine weeks before you want to gather fruit. Plants ex- 



watering, and at the same time cutting off all the leaves ; when 

 thus treated, they will in the year following, produce as good 

 crops in forcing as fresh potted plants. If not wanted for this 

 purpose, they may be turned out into the natural ground, and 

 will then bear a crop in the autumn of the same year, as de- 

 scribed by Williams above."

in proportion as the time of beginning to force approaches the

 ne latter observes, " those who force strawberries to a consi- 

 derable extent, perhaps 1000 pots, bring them in in different 

 successions, perhaps 100 or 200 at a time; that is in places 

 'Jhere there are several forcing houses. M'Phail says " when 

 ne weather begins to get cold in September, strawberries of the 

 Pjne kind in pots may be set in a forcing house or brick frame, 

 ^^^ if they be in good health, they will produce fruit for a con- 

 siderable time. They require only a gentle heat of from 50""

^n already noticed, begins to force alpines in November, the 

 Ty^ in January, and the pines in February and March.

 October till June.
