Propagazione della begonia dalle talee

Mia madre, la benedica, potrebbe radicare qualsiasi cosa tagliando gli steli da 4 pollici e mettendoli in un bicchiere di succo con un pollice d'acqua. Sedeva il bicchiere sul davanzale della finestra sopra il lavello della cucina, così da poter tenere d'occhio il livello dell'acqua e aggiungerne altri se necessario. In poco più di un mese, i suoi tagli di begonia avrebbero gettato radici minuscole e in due sarebbero stati pronti per il piatto. Puoi provare questo metodo anche per radicare le begonie. Ci sono tuttavia degli svantaggi. I gambi a volte marciscono, specialmente se la luce del sole è troppo diretta, lasciando una pastosità appiccicosa nel bicchiere e l'acqua del rubinetto contiene tracce di cloro, che può avvelenare i giovani germogli.

Per me, un modo più sicuro per propagare le begonie è piantare quei quattro gradi di begonia direttamente in un terreno in crescita. Radicare le begonie in questo modo mi dà più controllo sul contenuto di umidità del contenitore. Usa steli maturi per tagliare, ma non così vecchi che sono diventati fibrosi o legnosi. Taglia appena sotto un nodo. Rimuovere con cautela le foglie dalla metà inferiore dello stelo. Se hai l'ormone radicante a portata di mano, ora è il momento di immergere le estremità tagliate nell'ormone. Se non ne hai, va bene anche questo. La propagazione della begonia è altrettanto facile senza di essa.

Fai un buco nel terreno di semina con un bastoncino di cristallo (o se sei come me, usa quella matita sul bancone) e inserisci lo stelo nel buco. Tampare il mezzo per tenere il montante di taglio. Le begonie di radicazione non sono esigenti per il mezzo in cui sono cresciute fintanto che sono leggere e trattengono l'umidità.

Suggerimenti per la propagazione delle begonie da talee

Molti giardinieri preferiscono creare una mini serra quando propagano le begonie per mantenere il terreno uniformemente umido. Puoi farlo coprendo la pentola con un sacchetto di plastica o con una bottiglia di plastica con il fondo tagliato. Uno dei miei preferiti è rivestire la tua pentola con un sacchetto di plastica con alcuni fori infilati nel fondo per drenare. Riempire con terra, pianta, sollevare i lati del sacchetto e fissare con una cravatta di plastica. È possibile regolare il flusso d'aria e l'umidità aprendo e chiudendo la borsa.


TUMORE BATTERICO

Rogna, o cancro batterico, è presente soprattutto in olivo e oleandro. Si tratta di un’infezione dovuta all’attacco da parte di un batterio che penetra nel legno attraverso ferite dovute a traumi (ad esempio grandinate, gelate) o potature. Le giovani piante possono deperire, mentre quelle adulte di grande dimensione rallentano la crescita e riducono la formazione di fiori (oleandro) o la fruttificazione (olivo).


COME RICONOSCERLO
In questa stagione sui rami, nelle altre anche sulle foglie, si manifestano delle protuberanze tondeggianti o bitorzolute, grosse sino ad alcuni centimetri, di consistenza coriacea: si tratta di escrescenze di tipo tumorale di colore marrone scuro o grigio che induriscono velocemente.

DIFESA
È un problema abbastanza comune in piante vecchie e trascurate e non può essere eliminato: la pianta convive con il parassita. Adesso si possono tagliare le parti più colpite, bruciando tutti i residui di potatura. È indispensabile disinfettare gli strumenti di taglio con alcool o candeggina, prima e dopo aver potato esemplari infetti, al fine di evitare la diffusione del batterio. In autunno e in primavera distribuire ripetutamente prodotti a base di rame (ossicloruro di rame, poltiglia bordolese o altri più specifici) sulle zone colpite, sui punti di taglio e sull’intera chioma.
