I have planted more Begonias for putting on the balcony railings this summer. I also have hanging baskets with Begonias planted up on the balcony. The ones in the hanging baskets have been planted up since March 8th but there is no sign of them sprouting as of the present moment (11th April). Perhaps it was a mistake to plant the tubers directly in the baskets & then leave them outside on the balcony. I have so little room inside the flat that I took a chance on leaving them outside.
I think that the nocturnal temps are not high enough to persuade them to wake up.
I planted up 4 different varieties of Begonias in all. I put B.‘Cascade mixed’ in these relatively shallow baskets (4 baskets with two tubers in each) I also planted up B. ‘Pendula mixed’ (4 tubers in each of 2 big hanging baskets at either extreme of the balcony). These I planted up on March 4th.
I also potted up in 5" pots a pack of B.‘Fimbriata mixed’ which I then put in the cupboard in our hallway. I planted these up on 26th February & they had sprouted by the end of March. I moved them to our bedroom windowsill on April 2nd. I intend to plant these into the slightly bigger clay pots I have in rings on the balcony railings towards the end of May when all possibility of frost has passed. With a bit of luck I should have flowers from June to the end of October!
Finally I have some B.‘Non-Stop orange’ which I also planted up in pots & which are also sprouting & been placed in our bedroom windowsill with the others. Unfortunately I took them out & completely forgot I had 2 different varieties! Now they are mixed up on the bedroom windowsill &, until they start to flower, I won’t be able to distinguish which is which!
The Begonias I planted out in the hanging baskets on the balcony that I planted up about the same time as the others still show no signs of life! Probably been too cold for them lately. During the last week or so of April especially we have had some frosty nights & the day time temps haven’t been very good either. I just hope they haven’t rotted away or I’ll be in serious trouble this summer on the balcony as I have no other hanging plants I could put in their place.
On the positive side the Begonias in the bedroom window are coming on just fine but it will be at least another month, perhaps middle to end of May, before I get them into the clay pots in rings on the balcony railings.
