Why are some of my plants turning yellow when they were very healthy. What causes this?

Re: oh no 

Hi this can happen if there is to much water

Re: oh no 

Usually this is an indication of lack of nitrogen in the plant. Some plants are not too keen on the cold
and this often ties up any nitrogen.....give a feed of general purpose fertilizer in August ....Nitrophoska
blue is also a good quick source of nitrogen but is all
used up in about 3 weeks....works wonders though.
