browning outer leaf edges

20 years ago

I have seen a message posted earlier on where the leaf tips look burnt but the leaves are green and healthy...My cannas that I have in a pot in the greenhouse are doing this also...daytime temps are 90-100 and lows now are in the upper 60's but have been at 50's a week ago...it actually got down to 40's but are sheltered from the wind....what are the best temps high and low to grow cannas..and what should I do about those burnt looking leaves...will they recover or should I just remove them

Thanks

Steve
