Xa ubushushu bufikelela kuma-28°C, i-photosynthesis yengca yexesha elipholileyo iyancipha kwaye ukwenziwa kwe-carbohydrate kuyancipha. Ekugqibeleni, ukusetyenziswa kwe-carbohydrate kudlula imveliso yayo. Ngeli xesha, ingca yexesha elipholileyo ixhomekeke kwi-carbohydrates zayo ezigciniweyo ukuze igcine ubomi. Nokuba isityalo silele kwaye amagqabi alahlekelwa ngumbala wawo oluhlaza, isityalo sisaphefumla. Xa siyeka ukuphefumla, isityalo siya kufa.
Xa ubushushu bomhlaba bunyuka, izinga lokuphefumla liyanyuka ngokwenene. Ukongeza, ukuncipha kwe-photosynthesis phantsi kobushushu obuphezulu kubangela ukuba ukusetyenziswa kwe-carbohydrate kukhawuleze kunemveliso yayo. Esi sesona sizathu siphambili sokwehla kwe-summer bentgrass. Olu phononongo lukwagqibe kwelokuba umahluko phakathi kokuveliswa kwe-carbohydrate kunye nokusetyenziswa kuya kuncipha xa ukuphakama kokusika kunyuswa.
Uninzi lwabadlali begalufa lufuna indawo yokudlala eluhlaza, kwaye ukungalali ixesha elide kuya kubangela ukufa kwezityalo. Ukunkcenkceshela yindlela ebalulekileyo yokuthintela ukungalali, kwaye ezinye iindlela zinokuphucula amandla ezityalo okuphepha ukungalali, ukusinda ukungalali, kunye nokuchacha emva kokungalali. Uninzi lweendlela kufuneka zisetyenziswe ngaphambi kokuba kuqale uxinzelelo lwasehlotyeni, abanye abaphathi abalubiza ngokuba yi-"pre-stress conditioning", ngolu hlobo lulandelayo:
1. Ukuphakamisaukuphakama kokuchebaingenza inkqubo yeengcambu zengca ibe nzulu kwaye ixinene ngakumbi;
2. Ezinye iinguqu zesimo sendalo, ngaloo ndlela ziphucula ukumelana nembalela. Nciphisa ukunkcenkceshela ngaphandle kokuchaphazela umgangatho womphezulu wengca. Uxinzelelo oluncinci lwembalela phakathi kokunkcenkceshela okubini kunciphisa ukukhula kwamasebe kwaye kukhuthaza ukukhula kweengcambu. Ngokufanayo, ukunkcenkceshela okuphakathi entwasahlobo kunokukhuthaza ukukhula kweengcambu nzulu ukumelana nobushushu basehlotyeni kunye nembalela. Nangona kunjalo, phantsi koxinzelelo lobushushu obuphezulu, kufuneka kuqinisekiswe ukuba kukho amanzi aneleyo ukuze ingca inciphise ubushushu bezityalo ngokuphefumla.
3. Kuphephe ukufaka initrogen entwasahlobo nasehlotyeni ukuthintela ukuba inxalenye engaphezulu komhlaba yesityalo ingakhuli ngokukhawuleza kwaye yonakalise ukukhula kweengcambu.
4. Khetha iintlobo zengca kunye neentlobo ezimelana nobushushu kunye nembalela
5. Khuthaza ukukhula kweengcambu nokomelela kwazo: Thatha amanyathelo okukhuthaza ukukhula kweengcambu unyaka wonke. Iingcambu ezinzulu nezixineneyo zinokuphucula ukumelana nembalela yengca kwaye zenze isityalo sikwazi ukufunxa amanzi amaninzi kuluhlu olubanzi lomhlaba. Ukumba imingxunya kwandisa ukungena komhlaba kwaye kuvumela ukukhula kweengcambu okuphucukileyo.
6. Ukupholisa umhlaba: Ukuvuthela umoya opholileyo ukuya kwindawo eluhlaza ngokusebenzisa umbhobho wokukhupha amanzi kusetyenziswa kakhulu kumazwe aseNtshona.
7. Ukupholisa ingca:Ukutshiza kunye nokupholisaingca iphuma emanzini.
8. Ukunciphisa ukunyathela: Nciphisa ukunyathela okanye ukungena engceni ehlotyeni.
