• kuti asike siyana ivhu wemisanganiswa uye kupa zvinodiwa friability uye porosity;
• kana kuwedzera hydroponic zvirimwa;
• somunhu abudise rukoko dzakasiyana-siyana chirimwa sezvo muhari, uye mubindu miti;
• Pevhu yokudyara;
• nokuti chando chengetedzo uye klubnelukovichnyh siyana bulbous zvirimwa: vermiculite kwete chete anotsigira kwomuzvarirwo tembiricha uye gasi ezvinhu, asiwo zvinotadzisa kurasikirwa yokudyara zvinhu nehosha dzakasiyana-siyana uye utachiona;

2. Sezvo absorbs mvura yakawanda kwenguva yakareba uye anohupa zvinomera, zvinofanira kurangarirwa, uye kuti tisanyanyozvidya achidiridzira izvo zvingaita kuti waterlogging ivhu uye chirimwa rufu.
3. Two chicherwa zvinhu - perlite, vermiculite - vane ehupfumi zvakafanana, vanogona kushandiswa pamwechete kukura zvinomera.
4. Zvakakosha kuyeuka kuti vermiculite interacts nemvura zvakaoma uye zvinogona "kufamba" kuti acidity ivhu iri alkaline divi. Ndokusaka nyanzvi dzakawanda dzinokurudzira kushandiswa yakaisvonaka vermiculite chete hunovambira mizambiringa yakabva kumwe kana kana tichishanda hydroponics zvirimwa kana murwiyo mvura yepamusoro anozivikanwa uye kugara.
