...... I even pulled out of small twigs, decades had grown wonderfully - no pests - they were cut every year my husband and enjoyed with their deep green. But this year was different ..... they were yellow in some places, lost leaves, we played to remove them even in thought ..... but before that I have made myself smart on the Internet and read for the first time something about cydalima perspectalis and the spray Calypso Bayer and of course the reviews. So we have injected the agent two weeks ago and today can be seen in the above sheet absent branches tiny new leaves - it is a pleasure - in any case I will buy this means again and preventively apply - so our 30 boxwoods look splendidly again.
