Kuyasiza kuwo wonke umuntu okhulisa lobu buhle endaweni yabo ukuze ajwayelane nolwazi ngezifo ezivame kakhulu ze-thuja. Lokhu kuzosiza ukwenza izindlela zokuvimbela ngendlela yesikhathi futhi kuvikele ukukhula kwesifo. Ngaphandle kwalokho, lesi sitshalo sizolahlekelwa yimisebenzi yaso yokuhlobisa, futhi ngeke sisayihlobisa lendawo ngokubukeka kwayo kwasekuqaleni.
I-Thuja ingumhlobiso omuhle wesimo somhlaba, kepha uma ithintwa yizifo nezinambuzane, lesi sitshalo siphulukana nokuhlobisa kwayo futhi asibukeki sibe yinhle kangako. Kufanele unake izifo ze-thuja kanye nokwelashwa kwazo ngesikhathi, isithombe salezi zifo sizosiza ekuboneni ukuthi yisiphi isitshalo esithintekile. Ngemuva kwalokho, kuthathwa izinyathelo zokuphuthumayo zokuvimbela nezokwelashwa.
Ukulimala okujwayelekile kakhulu okungakwazi nje ukonakalisa ukubonakala kwe-thuja, kepha futhi ukukuqeda, kufaka okulandelayo:
- I-Phytophthora.
- Kuphendula uBrown.
- Ukugqwala kanye shute.
- Isihlangu samanga sikaThuja.
Okuyingozi kakhulu i-phytophthora nesihlangu samanga se-thuja, okuholela kancane kancane ekufeni kwesitshalo sonke.
Nge-lesion enzima ngokulimala sekwephuzile, akudingekile kuphela ukususa ususe ngokuphelele, kepha futhi ukubuyisela inhlabathi, ngoba lesi sifo esiyingozi sokukhunta sisengaba semhlabeni iminyaka eminingana.
Yini okufanele uyenze uma iThuja isiphenduke nsundu emva kobusika?
Ngemuva kokubandza isikhathi eside ebusika, imvelo iqala ukuvela. Kungalesi sikhathi lapho umuntu angathola khona ngethukile ukuthi i-thuja ethandekayo isivele yaba nsundu ngombala futhi ayisasiletheli injabulo ngokuluhlaza kwayo. Kungenzeka yini ukubuyisela ubuhle bakhe bangaphambili nokuluhlaza okwedlule? Kwenzekani kulesi sitshalo?
Uma i-thuja ngemuva kobusika isiphenduke insundu, khona-ke okufanele ukwenze kuleli cala kufanele kunqunywe ngemuva kokuthola izimbangela zenkathazo enjalo. Izici okungenzeka kakhulu yilezi:
- ukushiswa kwentwasahlobo;
- umswakama ngokweqile;
- Umanyolo owedlulele;
- amanzi e-alkaline;
- ukwehlulwa yizilokazane noma izifo.
Ngemuva kokuthola izimbangela zalesi sifo, i-thuja yenza ukwelashwa kwayo. Isithombe sizosiza ekunqumeni ngokunembe ngokwengeziwe ukuthi kwenzekani ngempela ebuhleni obuhlaza. Ukuvimbela ukusha, ngoFebhuwari kunconyelwa ukumboza isitshalo nge-gauze noma ngenethi yomiyane. Uma bekungenakwenzeka ukuvimba imiphumela emibi yokukhanya kwelanga, khona-ke udinga ukuqala ngokunisela ngamanzi afudumele, futhi ngokuqala kokushisa okuqinile, unqume amagatsha amnyama.
Ngokuqina kwamanzi, inhlabathi ezungeze i-thuja iyathukululwa futhi iphathwe ngemithi ye-antifungal. Uma kutholakala ukuthi amanzi asemhlabeni asondele kakhulu kule ndawo, lapho-ke ukufakwa kwesihlahla kuphela kwenye indawo kuzosiza. Ukufaka umhlabathi kuphela ngonyaka, usebenzisa umquba ngalezi zinhloso.
Ukuze kutshalwe i-thuja, umhlaba obuthakathaka kuphela futhi onomhlaba omncane une-alkali ofanele. Uma kutholakala izinkomba ezandayo, kumele kuthathwe izinyathelo zokunciphisa. Uma kunesidingo, yenza i-lime noma i-peat.
Izifo zeThuja nokwelashwa kwazo kuya ngohlobo lwegciwane noma inkathazo eye yabangela lesi sifo. Abalimi abazinaki izimpawu zokuqala, futhi lesi sifo siqala ukukhula, emva kwalokho lesi sitshalo kufanele sichithwe. Ukuvimbela lokhu kungenzeki, entwasahlobo wonke amagatsha awomile futhi alimele kufanele asuswe ezihlahleni, futhi isitshalo eselashwa kufanele siphathwe ngamalungiselelo enzelwe ukuvimbela izifo ezinkulu nezinambuzane. Kuhle kakhulu ukufafaza ngengxube yeBordeaux.
Kuthiwani uma uThuja ephenduka emnyama emva kobusika?
Ngokuqala kokushisa nokuphela kobusika obubandayo, kutholakala ukuthi amabala amnyama avela kwi-arborvitae. Abalimi beNovice ngeke bakwazi ukuqagela imbangela yengozi enjalo. Iziphi izinyathelo okufanele zithathwe uma i-thuja isiphenduke mnyama emva kobusika? Yini okufanele yenziwe kulesi simo nokuthi ungasiza kanjani isitshalo?
Imvamisa, izimbangela zamabala amnyama ku-thuja zingcwayi zezilwane ezifuywayo. Kuyadingeka ukubhekisisa: uma amabala etholakala ngokungahleliwe futhi esezingeni eliphansi, khona-ke lokhu kunjalo. Ngeshwa, ngokunqotshwa okubanzi, mancane kakhulu amathuba okusindisa lesi sitshalo, kodwa inani elincane lamagatsha lingagezwa ngamanzi ahlanzekile. Ngemuva kwalokho, kubalulekile ukubeka uthango elizungeze i-thuja futhi ungavumeli ukuxhumana nezilwane ezifuywayo. Ngezikhathi ezithile, isihlahla sondliwa ngezinto ezikhulisayo.
Izifo zokukhunta ngo-Thuya nokwelashwa kwazo kuyindaba ebaluleke kakhulu. Ukuphapha olulodwa lapha akwanele. I-fungus nayo ingadala ukuba mnyama, kepha ukwakheka kwama-spores nakho kuyisici sako. Nge-lesion encane, i-thuja iphathwa nge-fungicide kabili, igcina isikhathi esingamaviki ama-1-2. Izingxenye ezilimele zesitshalo ziyasuswa, futhi kwenziwa ezinye izindlela zokuvimbela (ukufafaza ngenhlanganisela yeBordeaux noma i-biofungicides).
Izitshalo ezifile zingumthombo wokutheleleka, ngakho-ke udinga ukunakekela ukususwa kwazo okufika ngesikhathi endaweni. Amagatsha owonakalisiwe nawo ayasuswa futhi ashiswe ukuvimbela ukusakazeka kwalesi sifo kwenye insimu.
Uma i-thuja ibisibekele imbozwe, kepha ungagijimisi ukususa impahla eseyisembozo kuyo: udinga ukwenza lokhu kancane kancane ukuze lesi sitshalo sibe nethuba lokujwayela ilanga futhi singashisi. Uma isiza sitholakala endaweni evulekile elangeni, khona-ke ngasohlangothini oluseningizimu kungcono ukufaka isihlangu selanga. Ngokuhambisana nale mithetho elula, i-thuja izoba nempilo, iluhlaza futhi izosebenza njengomhlobiso wangempela wokubukeka komhlaba.
