I have replaced two dead Leylandii hedging conifers aged approx 20 years old with two 3/4 year old potted replicas. However after 2 months these replacements are starting to look a bit yellow from their bases. It wasn't practical for me to replace the soil around the trees but I did clear out a lot of builders rubble. Are the replacements short of a feed perhaps or is there likely to be something more fundamental? For information the two dead trees were in a line of a dozen others which remain seemingly healthy. Any ideas?
