I-oeriander yaseNerium, eyaziwa njenge-Oleander, i-laurel epinki okanye i-Rosebay, sisihlahla esinetyhefu engapheliyo okanye umthi omncinci, wosapho lwe-Apocynaceae. Inzalelwane eMntla Afrika nakwimpuma yeMeditera. Namhlanje iyachuma kuninzi lweFlorida, ngeenjongo zokuhombisa kwiipaki nakwindlela esemacaleni.
Nangona kuyinyani ukuba zonke iindawo zesityalo zinetyhefu xa zityisiwe, i-oleander ixabisekile ngobuhle bayo kunye neentyatyambo ezintle.
Iimpawu ze oleanders
UOleander ineentyatyambo ezinde namagqabi amnyama aluhlaza Kuwo wonke unyaka, ingakumbi kwiinyanga ezifudumeleyo, iintyatyambo eziqaqambileyo ezimile okweenkwenkwezi ziza zimhlophe, zipinki, zibomvu, yikorale, okanye tyheli, kuxhomekeka kudidi.
Kukho iindidi ngeentyatyambo ezizodwa kunye neentyatyambo eziphindwe kabini. Iintyatyambo ezizodwa zihlala zicocekile, ngelixa zichithwe iintyatyambo eziphindwe kabini zihlala zingathandeki kwisityalo. Nangona kunjalo, zii-oleanders ezihamba-mbini ezihlala zinevumba elithile.
Sisityalo sonyaka esineziqu ezininzi esikhula ngokuthe nkqo ukuya kuthi ga kwiimitha ezi-6 ukuphakama kunye neemitha ezi-3 ububanzi. Amagqabi abonakala ngababini okanye ngqindilili kathathu, angqindilili nangofele, abe ziisentimitha ezi-5 ukuya kwezingama-21 ubude neesentimitha ezi-1 ukuya kwezi-3.5 ububanzi.
Ukukhula nokunyamekela oleanders
Into yokuqala ekufuneka uyazi ukuba ufuna ukukhulisa isityalo se-oleander egadini, yile kufuneka ithintelwe kwimimandla yasekhaya apho abantwana nezilwanyana zasekhaya zidlala khona.
Zonke iinxalenye zamatyholo zinetyhefu kwaye umsi ovela kwii-oleanders ezivuthayo unetyhefu. Ukungenisa kunye nexabiso elincinci lamagqabi e-oleander okanye iintyatyambo zingabulala.
Nxibelelana namahlamvu kunye neentyatyambo, kunokubangela isikhumba esirhabaxa kakhulu kunye negalelo lakho. Soloko unxiba imikhono emide kunye neiglavu xa usebenza ehlathini.
Izicucu ze-Oleander zithathela iingcambu ngokulula. Ukwenza oku, sika ii-intshi ezi-15 zeengcebiso ezintsha ngexesha lentwasahlobo okanye ekuqaleni kwehlobo, uzibeke embizeni ezaliswe ngumhlaba.
Esi sihlahla sithambekele ekubeni sishiye ixesha elide, kucocwa okuqhelekileyo nge-0,6 m ukusuka emhlabeni, kwaye kufuneka ityalwe ngezona zityalo zikhula kancinci.
Oleanders Ziyadubula ukusuka entwasahlobo kuye ngasekupheleni kwehlobo. Ngaphandle kwengqele yasebusika, akukho nto iphazamisa i-oleander.
Phantse nawuphi na umhlaba oxutywe kakuhle uya kwenza; i-acidic okanye i-alkaline. Xa sele isekiwe, iyanyamezela imbalela. Ikwamelana nokutshizwa ngumoya kunye netyuwa, isenza ukuba sibe sisityalo esifanelekileyo sokutyala elunxwemeni.
Emva kokudubula, nciphisa izityalo kwaye uziyeke ziphumle iiveki ezimbalwa. Ukuba ukusika kuyanqweneleka, thatha kwimithi evuthiweyo. Ukuthengela ukuze ubumbe isityalo kungenziwa nangaliphi na ixesha. Coca kwaye ulahle nakuphi na ukungcola emva kokuba kuthenwe.
Izifo ze-Oleander
I-Oleanders inokuthi ihlaselwe ngama-mealybugs, i-glass-wered shearing, isikali esithambileyo, i-oleander aphids kunye nezikali ezimhlophe. Faka izitshizi ezinesibulali-zinambuzane seoyile ye-neem.
Umbungu oleander Kuqhelekileyo kufumaneka kule shrub kwaye kuthanda ukutya amaqabunga ayo. Ezi mibungu zinokungakhuseleki kwiityhefu zomthi. Ukushiya kungakhange kuhlolwe, kunokubangela ukuba kungabonakali kakuhle. Oku akunakusibulala isityalo, kodwa kwenza ukuba ibe sengozini kwezinye izinambuzane, ezinjengezinambuzane ezilinganayo.
Ukutsha kwamagqabi e-Oleander sisifo esiyingozi esibulala amatyholo e-oleander. Iingcali zikhomba kwizizathu ezibini zokutsha kwe-oleander, ibhaktiriya i-Xylella fastidiosa kunye nesitshabalalisi esizisasazayo, umchebi onamaphiko eglasi.
Ukuba amagqabi atshintshiwe aluhlaza okomhlaza okanye ukuba imithambo yamagqabi ibonakala ngokulula kuba imnyama kakhulu, unobangela unokusilela kwentsimbi. Esona sizathu sixhaphakileyo asikokusilela kwesichumisi, kodwa lixabiso le-pH elingalunganga emhlabeni.
