Show COMMERCIAL IMPORTANCE OF RASPBERRY " Fruit Demands Care In Pick lira and In Handling Thereafter They Should Never Be Picked Wh(n Wet Of an Exquisite, Delicate Flavor. (Dy It. S.

I Tho European red raspboruT, Rubus Idaous, Is llttlo grown in this country. Tho fruit Is similar to tho Avmorlcan red raspberry In appcarancfj, of bot-tor bot-tor quality, but tho plants Jaro Icbb hardy. Tho early nttompttl at 'red raspberry culture In this couijtry wore largoly confined to tho dovtelopment of this species but theso h'&Vo nevor succeeded becauso tho spoVclcs is not adapted to our climatic conditions. Tho American red raspbo.Try, Rubus strigosus, is of comparatively rccont domestication.

This wild raspberry of tho mountains Is far superior inequality to tho domostlcated borry or to)' tho wild berry of tho east.

Tho raspberry haa reached 1 b greatest great-est commercial Importance In tho northcastorn states. This is because tho fruit domandB a cool cllmnto aAd n looso, moist soil with an abundance of humus. In a wild stato both tho rod and black varieties aro found at their best on newly cleared timbor lands of tho eastern and central states. Land from which timbor has beon romoved In tho enst is nearly alwayB first occupied by tho raspberry raspber-ry brambles. After tho surfaco humus hu-mus becomes moro or less exhausted thoso bushes disappear. Tho great drawback to raspborry growing either in a wild or cultivated Btato Is tho droughts that nro apt to occur at tlmo of ripening. Propagation of tlio raspberry varies according to which species It belongs. Tho red raspberries aro propagated from tho suckors which como up from tho parent root As n rulo most of tho red varieties throw up enough suckoro to lnsuro plenty of young plants. For this reason careful cultivation cul-tivation has to bo resorted to In order or-der to avoid Injuring tho root systom of tho old plant. For when It Is Injured In-jured It acts only as a stimulant to throw more shoots nnd ofton requires n sovero pruning to keep thorn down. Tho old plant can bo separated by division thus obtaining oxtra plants for plnntlng purposes, but as a rulo this is not ns good a plan as to use tho young Bhoots with tho roots attached. at-tached. The black raspberry Is propagated by tho tip layerago. This Is done by covering tho tips along tho latter part of July or tho first of August Thoy tako root at this point and generally gen-erally establish thomselves well can bo sopnratod from tho ' parent stock by cutting tho cano off near tho ground. Tho- purplo cano varieties vary somowhat Jn tholr mode of propagation propaga-tion according to tho variety. Tho most of them howover resemblo the black-cap In this respect and are propagated by tip layerago. |
