I have recently inherited two plants from a friend. One is a mum, the other is a begonia. The mum came with a lot of buds, so I thought I would have flowers, however they have opened and look like straw. I cut those off and have some new buds. Some look like they already are dry in the bud, so I removed those, but left the completely closed buds for now. The leaves look very good. Is there anything I can do to help it?
I have attached pictures of the begonia because I don't know the type. I have never had a begonia before. It looks okay after removing the dead flowers, but there were some leaves that looked fine but were completely dry through one stripe in the middle, where they broke off. The rest of the leaf wasn't dry in those cases. Some of the healthy flowers also came off very easily, but the plant has new growth and other than being uneven, looks good.
I think both could do with repotting. Is it safe to do that at this time of the year? Do either (particularly the begonia) need a special mix? Should I put the begonia outside? I worry about our nights, which are still not very warm (down to 8-10 Celsius); and the wind, which can go up to 23mph gusts at this time of year (though I do have sheltered areas).
