Hydrangeas yog ib qho ntawm ob peb cov kua qaub-hlub nroj tsuag uas zoo tshaj plaws hauv cov av uas yuav tua tau lwm cov nroj tsuag. Ntxiv nrog rau cov av tsim nyog, cov as-ham kuj tseem ceeb heev. Muab cov khoom noj ntxiv rau hauv daim ntawv ntawm cov chiv hauv tsev txhawb nqa cov nroj tsuag muaj peev xwm tsim cov paj sib sib zog nqus xiav mus rau ntshav-liab paj. Cov xim feem ntau nyob ntawm tus nqi pH ntawm cov av, uas yog vim li cas hydrangea hloov nws cov paj xim los ntawm xiav mus rau paj yeeb thaum fertilized nrog txiv qaub. Vim li no, hydrangea growers feem ntau siv acidic chiv rau lawv cov nroj tsuag.
Nutrients
Tsuas yog vim tias tsob ntoo nyiam cov av acidic pH tsis tau txhais hais tias hydrangea xav tau cov as-ham txawv dua li cov nroj tsuag loj hlob hauv cov av calcareous. Ib tug hydrangea tseem xav tau nyob ib ncig ntawm 13 lub ntsiab kom muaj kev noj qab haus huv, ib yam li lwm cov nroj tsuag. Qhov sib txawv tsuas yog tias hydrangeas tsis tuaj yeem nqus cov as-ham yam tsis muaj acidic ib puag ncig. Ib qho hydrangea yuav tsum zoo dua yog fertilized nrog nitrogen-raws li chiv uas muaj me ntsis phosphorus. Cov chiv tshwj xeeb hydrangea muaj los ntawm cov khw muag khoom tshwj xeeb, tab sis hloov pauv tag nrho cov chiv rau azaleas lossis rhododendrons tuaj yeem siv, vim tias cov nroj tsuag muaj cov kev cai zoo ib yam li hydrangeas. Feem ntau universal chiv rau flowering nroj tsuag muaj siab heev ib tug phosphate ntsiab lus rau hydrangeas thiab yog li tsis tsim nyog. Ntau cov phosphate nyob rau hauv cov av ua rau xiav-flowered hydrangeas kom paj liab dua vim hais tias cov txhuas lub luag hauj lwm rau cov xim xiav yuav tsis absorbed.
Basic mix rau fertilizer
1. Khoom noj khoom haus
Yog tias koj ua koj tus kheej chiv rau hydrangeas, koj yuav tsum siv cov ntaub ntawv uas muab cov as-ham txaus uas hydrangeas xav tau. Ntawm chav kawm, tsim nyog npaj ua chiv rau hydrangeas tuaj yeem yuav los ntawm lub vaj chaw. Tab sis qhov no tsis yog qhov tsim nyog kiag li, vim hais tias leej twg uas muaj lub vaj teb yeej muaj txhua yam lawv xav tau los tsim cov chiv tsim nyog rau hydrangeas. Cov ntaub ntawv no muaj pub dawb, thiab qee qhov ntawm lawv yog cov khoom pov tseg. Lwm tus tuaj yeem ua sai sai thiab siv zog me ntsis.
Cov khoom lag luam zoo rau hydrangeas suav nrog:
- worm av (cov kab mob hauv av los yog kab pos nphuab)
- Algae khoom (xws li nuv ntses algae los ntawm lub vaj pas dej)
- puab ntoo thuv
- Alfalfa hmoov
- Compost
Ua ke nrog zoo-ripened, crumbly compost, qhov sib tov no yuav muab cov hydrangeas nrog tag nrho cov as-ham lawv xav tau thaum cov av tseem acidic.
2. Additives rau qhov zoo pH tus nqi
Hauv qhov xwm txheej, hydrangeas nyiam loj hlob ntawm peaty heathland lossis hauv thaj chaw moorland. Dab tsi ntawm tag nrho cov cheeb tsam no muaj qhov sib xws yog tias cov av muaj pH qis heev. Ib txwm vaj av feem ntau tsis tuaj yeem muab cov xwm txheej no. Cov av ib txwm tsuas yog me ntsis acidic (nyob ib ncig ntawm 6-6.5), cov av clayey lossis clayey av tseem yog alkaline. Vim li no, nyob rau hauv yuav luag txhua lub vaj, cov chiv sib tov rau hydrangeas yuav tsum yog ib txwm acidic. Yog hais tias tus nqi pH twb zoo lawm, ntxiv acidic chiv yog nyob rau hauv feem ntau unproblematic kiag li. Ob peb hom hydrangea nyiam cov av alkaline, thiab cov acidifying tivthaiv yuav tsum tau zam thaum fertilizing lawv.
Acid khoom rau chiv:
- peat
- peat moss
- koob koob los yog koob spruce
- crushed conifer bark
- kas fes (kuj reacts me ntsis acidically)
Alkaline cov ntaub ntawv rau chiv:

Paj xim ntawm pH sib txawv
Qee yam ntawm hydrangeas muaj peev xwm tawg xiav yog tias cov av zoo. Tus nqi pH hauv av feem ntau yog lub luag haujlwm rau qhov no. Cov no suav nrog vaj hydrangeas (Hydrangea macrophylla), tseem hu ua tus neeg ua liaj ua teb hydrangeas, Japanese hydrangeas lossis potted hydrangeas.
- paj xiav: pH tus nqi qis dua 5.5 (4.0 txog 4.5 yog qhov zoo tshaj)
- paj paj yeeb: pH tus nqi siab dua 6.5
- Ntawm pH theem ntawm 5.5 thiab 6.5, cov hydrangeas tsim cov paj ntshav
Tip:
Yog tias koj txaus siab rau nws, koj tuaj yeem hloov xim ntawm koj cov hydrangeas txhua xyoo.
Blue xim
xiav hydrangeas feem ntau tawg paj liab dhau sijhawm. Qhov no tsis tas yuav yog qhov teeb meem, vim tias nrog kev paub me ntsis, hydrangeas tuaj yeem txuas ntxiv mus rau xiav. Paj yeeb hydrangeas kuj tuaj yeem dyed xiav (dua). Txawm li cas los xij, dawb huv los yog liab hydrangeas - tsis muaj teeb meem dab tsi tus neeg ua teb ua - ib txwm nyob dawb los yog liab, lawv tsis haum rau recoloring. Ntawm ib sab, tus nqi pH hauv av yog qhov tseem ceeb rau kev tsim cov paj xiav. Blue hydrangeas xav tau cov av acidic heev nrog pH ntawm 4.0 thiab 4.5. Ib qho kab hauv qab yog qhov kawg lub luag haujlwm rau xim xiav: aluminium. Qhov no kuj yuav tsum muaj nyob rau hauv txaus kom muaj nuj nqis nyob rau hauv cov av. Yog li yog tias tus nqi pH raug, tab sis hydrangea tseem tawg paj liab, nws tsis muaj txhuas. Qhov no tuaj yeem muab rau hydrangea nrog ntsev hu ua alum (potassium aluminium sulfate), uas muaj nyob rau ntawm lub tsev muag tshuaj lossis tau teev nyob rau hauv lub vaj chaw hauv qab hydrangea xiav. Fertilizers rau xiav hydrangeas yuav tsum muaj ib qho me me ntawm alum. Rau txhua fertilization, ib ncig ntawm ib mus rau ob tablespoons ntsev yog tov nrog chiv thiab incorporated rau hauv lub vaj av, zoo tagnrho rau lub caij nplooj ntoos hlav. Yog tias xiav hydrangea twb tawg paj liab, nws tuaj yeem siv li ob xyoos rau nws hloov xim dua. Yog li ntawd yuav tsum ua siab ntev me ntsis. Ntau npaum li cas ntawm alum tsis ua kom lub sij hawm luv, tab sis tsuas yog ua mob rau hydrangea.
Iron tiv thaiv chlorosis
Hydrangeas feem ntau raug kev txom nyem los ntawm cov tsos mob tsis txaus chlorosis. Chlorosis tuaj yeem pom los ntawm cov nplooj daj nplooj thiab cov nplooj daj daj. Qhov xim no yog vim tsis muaj cov kab hlau tsis zoo. Muaj ob qhov laj thawj rau qhov tsis muaj hlau. Ntawm ib sab, tsuas yog tsis muaj hlau txaus hauv av. Qhov thib ob, tej zaum yuav muaj hlau txaus, tab sis cov nroj tsuag tsuas yog nqus tsis tau nws. Qhov no yeej ib txwm yog thaum tus nqi pH hauv substrate siab dhau lawm. Los ntawm tus nqi pH saum toj no 5.5, cov hlau yog nyob rau hauv daim ntawv dej-insoluble, thiaj li hais tias nws tsis absorbed los ntawm cov nroj tsuag. Cov tshuaj tiv thaiv yog qhov yooj yim heev. Hauv thawj kis, tsuas yog me me ntawm cov hlau (hlau chelate fertilizer) yuav tsum tau muab sib xyaw rau hauv cov chiv. Nyob rau hauv rooj plaub thib ob, acidic fertilizer pab.
Special blend
Yog tias koj tsis muaj tag nrho cov khoom hauv koj lub vaj, koj tuaj yeem yuav cov khoom lag luam. Tom qab ntawd koj tuaj yeem siv cov khoom no rau lwm cov nroj tsuag acid-hlub tib lub sijhawm. Ib qho zoo hauv tsev hydrangea chiv muaj cov hauv qab no:
- Basic Cheebtsam: mature compost
- Seaweed khoom, crushed
- Peat (xws li peat moss, conifer bark, ntoo thuv lossis ntoo thuv koob)
- hlau nyuaj (chelated hlau) los yog hlau sulfate hauv kab
- Alfalfa hmoov, tseem hu ua alfalfa hmoov (siab nitrogen cov ntsiab lus thiab tsawg phosphorus)
- me me ntawm Epsom ntsev
- Horn shavings lossis horn pluas mov (kwv yees 12-15% N, tab sis tsawg dua 1% P)
- Alum rau xiav hydrangeas
Fertilize
Vim tias cov chiv no yog cov chiv organic nkaus xwb, cov as-ham raug tso tawm qeeb heev. Yog li ntawd, nyob rau hauv sib piv rau cov ntxhia chiv, ib tug loj npaum li cas ntawm fertilizer yog tsim nyog. Cov chiv tuaj yeem muab sib xyaw rau hauv hydrangeas 'av hauv tes hauv lub caij nplooj ntoo hlav thiab ntxiv rau lub Tsib Hlis lossis Lub Rau Hli. Rau potted nroj tsuag, nws yog pom zoo kom ntxiv chiv thaum repotting lawv txhua xyoo. Hydrangeas hauv cov lauj kaub me yog qhov zoo dua nrog cov kua chiv.
Kua chiv rau potted nroj tsuag
Yog hais tias lub hydrangea nyob rau hauv lub lauj kaub ntawm lub sam thiaj lossis terrace, thaum nws yog repotted rau lub caij nplooj ntoos hlav, ib feem zoo ntawm cov sib tov tshwj xeeb uas tau piav saum toj no yog tov rau hauv av. Qhov thib ob fertilization yog ua tiav nrog cov kua chiv uas koj kuj ua rau koj tus kheej. Txij li thaum chiv tsw tsw tsw tsw tsw, nws tsis haum rau houseplants. Cov tshuaj hydrangea hauv tsev ua kua hauv daim ntawv muaj xws li:
- 10 litre thoob
- dej
- Compost (txog 3 litres)
- Peat kom txo tus nqi pH
Hauv ib lub thoob qub, sib tov cov compost nrog dej me ntsis. Yog tias koj xav txo qis tus nqi pH, ntxiv ib mus rau ob txhais tes ntawm peat lossis peat moss thiab sau lub thoob nrog dej. Tawm hauv qhov chaw sov li 24 teev. Lub caij no, do ob peb zaug. Tom qab ntawd koj tuaj yeem tshem tawm cov khoom seem. Ua ntej siv, compost extract yuav tsum tau diluted nrog dej dawb kom txog thaum nws yog xim ntawm cov tshuaj yej tsis muaj zog. Txhawm rau kom nqus tau sai, cov chiv tuaj yeem txau rau ntawm nplooj nrog lub paj txau, thiab qee qhov kuj tseem siv rau cov hauv paus hniav ua dej dej.
Conclusion
Ib qho zoo hydrangea fertilizer yog ceev thiab yooj yim rau koj tus kheej. Dab tsi yog qhov tseem ceeb tshwj xeeb yog tias cov av pH tus nqi qis dua ntawm acidic Cheebtsam hauv cov chiv. Feem ntau cov hydrangeas nyiam cov av acidic heev nrog tus nqi pH ntawm 4 txog 4.5. Blue hydrangea ntau yam tshwj xeeb xav tau pH qis heev ntxiv rau txhuas los tsim cov xim xiav.
