my dahlias and begonias are still flowering but as weather is changing was thinking I should take them up for winter, should I wait for first frost
With dahlias, I usually wait until the foliage has gone black after they've been frosted. I've already lifted begonias, I usually do this when the days get shorter and chillier.
