Nzvimbo dzakasiyana-siyana mune zvicherwa zvadzo maererano ne geology yepasi, uye kusiyana uku kunobata hukama hwakashata kana kuti zvinyorwa zvevhu-imwe nhamba inoyerwa nehuwandu hwepH. Iyo pH yemari yepamusoro yepamusoro inomhanya kubva pa1 kusvika ku14, ine pH ye7 inomiririra zvematongerwe enyika. Nhamba dzezasi dzacho dzine acidic, nhamba dzakakwirira dziri alkaline. Izvo zvakakodzera pH hutano zvakakosha pamusana wekambani yekukwanisa kutora mishonga inoda kubva kune ivhu.
Kudyiswa kwesimbi kunonyanya kunetseka nehutongi pH mazinga.
Iyo ivhu rakaisvonaka pH yemarudzi akawanda mbeu uye maruva ehutu zvinenge zvakapoteredza 6.5, izvo zvishoma zvishoma. Asi pane zvimwe zvirimwa zvinoda ivhu rakawanda kuitira kuti ribudirire. Heano mamwe emiti inoda ivhu rakaoma:
Shrubs:
- Azaleas
- Rhododendrons
- Fothergillas
- Holly
- Gardenias
- Yakawanda shrubs yakawanda
Miti:
- Miti mizhinji yegreen

Zvirimwa zvinoda ivhu rakawanda kudarika zvavari kukura zvinowanzoratidza izvi kuburikidza nekugadzira iron chlorosis -kushayikwa kunokonzera mitsipa yekusiya kana mashizha akazara kuti atende. Kana izvi zvikaitika, mbeu yako inogona kudikanwa kuti uwedzere kugadziridza ivhu kune ivhu ravari kuwedzera, kana kuti iwe unowedzera kudiwa kwavo kwechidimbu nemushonga wakagadzirirwa kuipa.
Zvimwe zvakasiyana siyana zvekugadziriswa kwevhu uye fertilizer zvinowanikwa kupa rubatsiro urwu kune mbeu dzinoda asidi. Yakawanda inowanikwa nyore nyore pamunda wekurima uye kugadzirwa kwemisha.
Usati washandisa chero sarudzo yekugadzirisa, ita kuti ivhu rako riongorwe kuti rione mhando uye zviyero zvekugadzirisa kwevhu kunodiwa.
Sulfur
Sulfure inotora nguva yekuderedza ivhu pH , saka inofanira kuwedzerwa gore usati wada kudyara. Munzira dzakawanda, kunyange zvakadaro, ndiyo ndiyo nzira yakanakisisa. Iyo inoguma kwemakore muvhu uye inoita basa iri nani rekugadzirisa kupfuura mamwe akawanda kuchinja. Zvakanakisisa kushandisa sulfure muzhizha kana kuwira kusati kwasvika nguva yekusima kwegore, kuchichera mukati mevhu. Haiti kushanda zvakanaka kwazvo kuedza nekuchera sarufu kumativi ose aripo. Sezvo nechinangwa chipi nechipi, unofanirwa kuve nekuedzwa kwevhu kunogadzirirwa kuitira kuti uone kuti sulfur yakawanda inoshanda sei kuti uwane pH inoda.
Iron Sulfate
Iron sulfate lowers pH asi inoda kuwanda kukuru kwechigadzirwa kuti zvive nemigumisiro yakafanana sarufu. Inowanzoshandiswa kurapa zviratidzo zvakakwana zvekushaiwa kwesimbi. Iron sulfate inopa mhinduro dzinokurumidza kupfuura sulfur (mumatatu matatu kana mana) asi inogona kukanganisa michero kana kupfuura-yakashandiswa. Inogona kuvharirwa muvhu sehupfu, kana kushandiswa mugadziriswa uye kunwisa pamusoro pemashizha kuti iwane.
Sphagnum Peat Moss
Kana inoshandiswa muhuwandu hwakaita shanduko yevhu, peat moss inogadzirisa zvishoma ivhu iyo ichiwedzerawo zvigadzirwa zvehutu kune ivhu. Paunenge uchigadzira ivhu rako rokudyara, isa 4 kusvika ku 6 masendimita e acidic peat moss kumusoro kwako uye kusvika pakudzika kwemasentimita matanhatu.
Izvi zvichaita kuti ivhu riitwe kwemakore anenge maviri.
Acid Fertilizer
Kana mbeu yako inoda asidi yakasarudzwa pakati pezvimwe zvisati zviri asidi, zvinogona kunge zvisingashanduki kugadzirisa ivhu, sezvo kuwedzerwa kwe acidity kunogona kukanganisa mamwe mimwe miti. Pano, iyo yakanakisisa ndiyo yekushandisa fungidzeri ine imwe yemishonga yakasanganiswa nemvura inowanikwa, yakadai seMiracid. Tanga nekugadzirisa zvinyoro zvishoma kusvikira iwe uchinzwisisa zvinoshandiswa pamiti yako.
Aluminium Sulfate: Shandisa Kuchenjerera
Powdered aluminium sulphate yave yakave ivhu rakawedzerwa nevhu vemizambiringa vari kukura blueberries nemimwe mimwe michero sezvo ichikurumidza kuita uye yakakosha yekuchera mukati pemiti imwe neimwe. Zvisinei, kune zvingangove zvichange zvichinyanya kuitika pamusoro pezvinogona kuitika zvinokonzerwa nealuminium toxicity, iyo inogona kukuvadza zvikuru vana. Aluminium inogona kunyanya kunwa kubva kunwa mvura, uye kushandiswa kwakanyanya kwealuminium sulphate sezvo shanduko yevhu ingaita kuti kuve nekusvibiswa kwemvura pasi pemvura.
Nyanzvi dzakawanda zvino dzinokurudzira kuti aluminium sulphate ishandiswe chete pa hydrangeas, uko iyo aluminium inobatsira kusika maruva akajeka akajeka ayo anokoshesa. Kune zvimwe zvirimwa, zvisarudzo zvakachengeteka zviripo, zvakadai seammonium sulfate.
Ammonium Sulfate
Iyi ndiyo imwe nzira yakanaka kune aluminium sulfate. Inogona kuvharirwa muvhu rakapoteredza nheyo yemiti kuti iwedzere ma sulfuri muvhu. Zvinoda kutarisirwa, zvisinei, nokuti zvinogona kupisa michero nekuwedzera mashizha asidi nokukurumidza.
