Japanese red maple


Question: Japanese red maple

Last year in spring I bought this beautiful plant, I arrived home and transplanted it in a pot a little bigger, and not being able to find a shady spot on my terrace I had to keep it in the sun. Obviously all the leaves are dry, at the end of the summer I removed all the dry leaves and the plant put new leaves, but in the winter it returned to dry all the leaves. Now on the branches where it had the leaves before there is nothing but on the stem from the base some twigs with their own leaves are sprouting. I wanted to know if it is appropriate to prune it at the top to help those who are going out. Thanks for the reply


Answer: Japanese red maple

Eliminating the now dry top will allow the wild variety to live but will lose the Japanese red maple charm.

Consigli per la coltivazione dell’Acero

Poche cure per risultati sorprendenti. Coltivare l’Acero in giardino è davvero semplice, mentre qualche accortezza in più è necessaria quando si parla di coltivazione in vaso. Hai letto bene. Sono diverse le specie di Acer che non si sviluppano molto in altezza che possono essere anche coltivate in vaso.

Scopriamo come prendersi cura di questa pianta utile per completare grandi spazi o per arricchire con stile grandi terrazzi.

Coltivazione dell’acero in vaso

The specie asiatiche ben si prestano ad una coltivazione in vaso e riescono a svilupparsi anche in particolari condizioni, come gli spazi più ristretti.

Subito dopo aver acquistato la specie a portamento compatto è necessario metterla a dimora in vaso di terracotta di dimensioni medio-grandi (almeno 70cm di diametro e una profondità tale da coprire tutto l’apparato radicale con una quantità di terriccio idonea anche a garantire equilibrio al vaso quando la pianta crescerà). Il periodo migliore per l’impianto dell’Acero giapponese(sia in vaso che in piena terra) è compreso tra ottobre e marzo.

L’Acer palmatumè la specie giapponese di Acero rosso più adatta alla coltivazione in vaso e non richiede particolari cure per crescere sana e forte. Meglio non posizionare il vaso in zone esposte per molte ore al giorno alla luce diretta del sole. Il contenitore deve essere riempito con terriccio di buona qualità, così da garantire alla pianta un substrato leggermente acido e leggero, con una discreta quantità di materia organica. Inoltre, è consigliato creare uno strato inferiore di sabbia per aumentare le capacità drenanti del terreno da mantenere costantemente umido, evitando ristagni.

L’Acero coltivato in vaso ha bisogno di qualche intervento di concimazione. Un prodotto granulare a lenta cessione può andar bene per le concimazioni di fine inverno. Gli Aceri rossi giapponesi non tollerano lunghi periodi di siccità, quindi è bene intervenire non appena il substrato si secca negli strati superficiali.

Coltivazione in piena terra

Tra le piante più belle da mettere a dimora nel tuo giardino, l’Acero occupa una delle posizioni più prestigiose. La forma della chioma e i magnifici colori delle foglie rendono la maggior parte delle specie perfette per rendere unici spazi di varie dimensioni.

  • scavare una buca molto profonda per la messa a dimora definitiva della specie scelta. La larghezza e la profondità devono essere il doppio della porzione di terriccio utile per coprire tutte le radici.
  • Lavorare bene il terreno e arricchirlo con torba e una piccola quantità di sabbia di fiume.
  • Dopo l’impianto coprire il terreno con uno strato di pacciamatura (stallatico maturo o foglie) per mantenere un buon livello di umidità e aumentare la protezione per l’apparato radicale.

La messa a dimora dell’Acero in piena terra deve essere effettuata solo quando l’apparato radicale della pianta si è completamente sviluppato. Procedere preferibilmente alla fine dell’inverno prima dell’apertura delle gemme.

Coltivazione in terrazzo

L’Acero giapponese è una pianta perfetta per abbellire i terrazzi di grandi dimensioni. Basterà collocare il vaso in una posizione di mezz’ombra e al riparo dal vento per ottenere buoni risultati. Nessuna paura durante l’inverno: la maggior parte delle specie sono abbastanza rustiche.

Temperatura

Il freddo non rappresenta una minaccia per le specie di Acer occidentale. Qualche problema, quando l’inverno porta con sé temperature molto rigide, potrebbe sorgere per le altre specie asiatiche. Infatti, mentre gli alberi appartenenti al primo gruppo riescono a sopportare anche temperature al di sotto dello zero, le specie ornamentali più piccole di Acero giapponese necessitano di una protezione invernale, specialmente quando coltivate in vaso.

Durante l’estate, invece, è consigliato effettuare regolari annaffiature per mantenere il substrato sempre umido durante lunghi periodi di siccità e quando le temperature si alzano notevolmente. Per le piante coltivate in vaso si può procedere anche a nebulizzazioni sulle foglie, così da evitarne l’accartocciamento e il disseccamento a causa del troppo caldo.

Dove piantare l’Acero? L’esposizione ideale per coltivare in sicurezza le più belle specie che fanno parte di questo meraviglioso gruppo di alberi da giardino è a Est o Nord-Est, scegliendo sempre una posizione di mezz’ombra. Meglio evitare la luce diretta del sole.

Terriccio

Il substrato ideale per l’Acer deve avere un pH leggermente acido, deve essere leggero e ben lavorato, perfettamente drenante (umidità sì, ma niente ristagni) e ricco di sostanza organica (può essere aggiunta e mescolata al terriccio prima della messa a dimora definitiva della pianta).

Annaffiatura

Le annaffiature devono essere frequenti ed abbondanti nel periodo immediatamente successivo all’impianto. L’apparato radicale dell’Acero presenta una fitta rete di radici fibrose in superficie che richiedono un notevole apporto di acqua.

Quando annaffiare? La regola è la stessa sia per le piante coltivate in vaso che per quelle coltivate in piena terra. Le innaffiature devono essere fatte ogniqualvolta il terreno inizia a seccarsi negli strati superficiali, intervenendo sempre per contrastare lunghi periodi di siccità, con lo scopo di mantenere un elevato livello di umidità.

Moltiplicazione

La riproduzione dell’Acero può avvenire per stratificazione dei semi o per talea:

  • nel primo caso, le samare si aprono lasciando cadere i piccoli semi (meno di 10mm di lunghezza), che si disperdono sul terreno e vengono trasportati in lungo e in largo dal vento. There moltiplicazione per seme può avvenire anche per mano dell’uomo, mettendo i semi in un contenitore trasparente (un vaso dalle pareti molto sottili o una busta di plastica resistente) riempito con della sabbia. La germinazione avverrà circa 3 mesi dopo.
  • There riproduzione per talea è un’operazione da fare prima dell’arrivo dell’inverno. Ottobre è il mese ideale per procedere. Come fare? Basterà staccare un rametto giovane (lunghezza di circa 15-20cm) con almeno una gemma e sistemarlo in un contenitore appositamente riempito con terriccio morbido e drenante. Pian piano l’apparato radicale inizierà a svilupparsi e sarà possibile spostare la pianta in un contenitore definitivo o potrà essere messa a dimora in piena terra.

Concimazione

L’Acero non è un albero che richiede particolari interventi di concimazione, ma durante il periodo primaverile e autunnale è possibile somministrare un concime granulare a lenta cessione (molto leggero e ricco di amminoacidi). Prima dell’impianto si può arricchire il terreno con dello stallatico maturo.

Potatura

Essenziale! La potatura dell’Acero è essenziale!

Stiamo parlando di alberi che sviluppano una grande chioma (alcune specie più, altre meno) e che, quindi, per mantenere una allettante armonia delle forme necessitano di specifici interventi ogni anno. La potatura può avere lo scopo di rendere la chioma più ordinata o un fine puramente contenitivo quando lo spazio attorno alla pianta non è tantissimo. Oltre che intervenire sui rami basali negli esemplari più giovani, è sempre consigliato eliminare i rami secchi o spezzati. È potare in inverno o prima dell’apertura delle gemme (marzo è il limite massimo).

Consociazione

Le specie ornamentali di Acer ben si prestano a far da cornice a giardini rocciosi di ogni dimensione, così come possono essere utilizzati per delimitare ampi prati. Le colorazioni autunnali molto vivaci delle più belle specie asiatiche possono trasformare qualsiasi giardino in un regno incantato, specialmente quando attorno alle singole piante si creano delle aiuole con piante a fioritura autunnale/invernale. Consigliato è l’abbinamento Acer palmatum is Hosta. Per quanto riguarda l’abbinamento con altri grandi alberi da giardino è possibile seguire due semplici regole: calcolare le dimensioni delle piante in base alla superficie del giardino e lasciare campo libero alla fantasia.

Caratteristiche

Un albero particolarmente diffuso nei giardini delle abitazioni è l'Acero Giapponese, un albero deciduo originario dell'Asia. Ha un portamento differente a seconda della specie che può essere arbustivo oppure assumere le dimensioni di un albero vero e proprio. La sua caratteristica che lo rende così apprezzato da giardinieri e da chiunque disponga di un giardino è la colorazione delle foglie che possono variare da un rosso acceso, al color fegato oppure possono addirittura presentare delle screziature bianche. Straordinaria, infatti, è la sua presenza soprattutto nel periodo autunnale in cui esprime tutta la magnificenza del fogliame palmato che, cadendo, realizza un tappeto degno di nota. Viene impiegato anche nei parchi pubblici data la sua resistenza allo smog e alla possibilità di crescere senza richiedere cure particolari.

I metodi e gli accorgimenti per la coltivazione

La coltivazione dell'Acero Giapponese è piuttosto semplice anche grazie allo sviluppo contenuto della sua struttura. Può essere messo a dimora sia in un grande vaso, preferibilmente le varietà nane, sia in piena terra perché tollera efficacemente le gelate e gli inverni rigidi. La crescita è variabile, mediamente una pianta di Acero cresce tra i 2 e i 5 metri a seconda dello spazio in cui può espandersi. The terriccio in cui viene piantato deve essere soffice e leggero, ricco di materia organica e con un pH tendente all'acido poiché non riesce a valorizzarsi in un substrato alcalino o calcareo. Le irrigazioni non devono essere frequenti ma è bene evitare che il terreno si asciughi soprattutto per non danneggiare le piante giovani. Per gli Aceri più anziani messi in piena terra non saranno necessarie giacché tutte le sostanze nutritive sono reperite dalle radici. Qualora fosse posto in un vaso, durante il periodo invernale bisogna porre attenzione che il terriccio non si secchi bagnandolo occasionalmente. Sono da evitare i ristagni idrici, molto pericolosi per la salute della pianta poiché ne causano marcescenza e in seguito la morte. Per questo motivo l'Acero va piantato in una zona umida ma non bagnata, preferibilmente in lieve discesa per favorire il deflusso dell'acqua. Ama la mezzombra, quindi bisogna evitare di esporlo in pieno sole, inoltre vanno evitate anche le correnti d'aria e le zone ventose che possono rovinarne la crescita e l'espansione della chioma.

Curiosità sull'Acero Giapponese

Nella simbologia delle piante, l'Acero Giapponese è, ovviamente, una delle piante che rievoca la nazione nipponica, infatti, ne è un simbolo molto diffuso. L'importanza data a quest’albero è simile a quella dei ciliegi, particolarmente cari alla popolazione giapponese. L'Acero simboleggia l'eleganza and the grazia tanto che è stato di frequente decantato in innumerevoli poesie degli scrittori del sol levante. Numerose sono le raffigurazioni pittoriche, nello specifico le tradizionali stampe su carta o legno. Questa pianta, infine, è una tra le essenze preferite nella realizzazione dei bonsai, ovvero gli alberi miniaturizzati che vengono cresciuti in piccoli vasi di ceramica. Per questa ragione vengono scelte le specie più piccole ed esteticamente piacevoli per il colore intenso del loro fogliame. Una tipologia di questa tecnica prevede la rottura del fusto in senso longitudinale oppure la crescita della giovane piantina su una roccia per anni finché non si salda al materiale sottostante in maniera armoniosa.
