leaves turning Yellow

Question

We have planted, in outdoor pots, several Euonymus kiautschovicus shrubs. Some of the leaves are turning yellow. Some have no spots just yellow other have marks I have attached photos. Thank you Rebecca Valentini 

Answer 1

There are a few things that could be the issue here. You may have a nitrogen deficiency in the soil, an issue with dry or clay soils that won't retain enough water, or (funny enough) overly-wet soils. Make sure that you are fertilizing at least once a year if not just a few times. Alternatively, it may be changing due to cool weather, as this can happen if the nights are cool.
