FORCING DWARF TOMATOES UNDER GLASS 67 



practically doubles that of the standards for one crop in the 

 spring, or on the other hand produces as much and more from 

 the one continuous fruiting than is yielded by two crops of 

 the tall varieties. 



It may be said, however, that it is possible that our dwarf 

 varieties have a slight advantage in that they represent 2^ 

 square feet of soil, while those of the tall-growing varieties 

 are said to range from i^ to 2 square feet. By starting the 

 plants much earlier and allowing the dwarfs the entire use of 

 the beds as is the case with the two crops of tall varieties it is 

 believed the dwarfs will more than sustain their reputation. 

 That the dwarf tomatoes are more profitable at least for a sec- 

 ond crop there can be little question. 



Distance to Plant. — The distance that is best adapted for 

 planting dwarf tomatoes to be trained to one stem seems to be 

 iS inches each way. B}^ planting them this distance and doing 

 considerable pruning the plants do very nicely. The leaves 

 are large and heavy and obstruct much light unless well 

 pruned. This was the distance the trial varieties were given, 

 and it proved very satisfactory. 



Insects., Fungus., and Pests. — There are many things liable 

 to break out and cause more or less trouble, but most of these 

 are easily handled if taken in time, or better if anticipated and 

 kept away. The only serious trouble that we had to contend 

 with the past season was an attack of Aleyrodes. Other com- 

 mon names of this insect we find are '*■ White-fiies," and 

 *'' Mealy Wings." They are very small, white fiies. VVe paid 

 no attention to them at first as they did not seem to be doing 

 any trouble. They did not appear until late in the season but 

 kept increasing in numbers until at the end they were seriously 

 afiecting the plants. The adults deposited eggs on the under 

 side of the leaves which hatched into louse-like nymphs which 

 adhered very closely to the leaves and evidently sucked out 

 much of the sap of the plant. We attempted different meth- 

 ods of spraying with kerosene and water at different strengths. 

 If taken in time this doubtless will prove a satisfactory remedy 

 but our experiment was about over and the plants were pulled 

 and destroyed. We predict this insect would prove very destruc- 

 tive if it should become well established early upon a crop.
