Pred nekaj leti smo imeli na dovozu zasajene bele borovnice, da bi ga izklopili iz hiše. Zdaj, na strani ceste, je šest dreves rjavih in umirajočih. Ali lahko pojasniš, zakaj se to dogaja? -Melissa Onofrio, Meriden, CT
A:Sodeč po fotografijah, ki ste jih poslali, je glavna težava pri vaših drevesih nezadostna sončna svetloba, zaradi zrelih dreves, ki senčijo vaš dovoz. Tako kot večina iglavcev, bele borove ne rastejo dobro v senci, in ko so zasenčeni, se odzovejo z igle za odvajanje. Dejstvo, da se vrhovi vašega drevesa nagnejo od dovoza in do najsvetlejšega dela neba, jasno kažejo na to, da so sončna svetloba odvzeta.
Ampak to ni edina stvar narobe z vašo živo mejo. Tudi če so drevesa dobivala dovolj sonca, so bila zasajena preveč blizu skupaj in preblizu na dovozu. Bele borovnice je treba posajati približno 16 čevljev narazen in vsaj tako daleč od dovoza, da se med seboj ne zasenčijo ali ne potresajo proti vozilom.
