Gooseberry sawfly....I use neem oil after thoroughly clearing away debris around the bushes. Spraying soil and thoroughly drenching all parts of the bushes. then a thick mulch. No sawfly for me.
sanjy, re cosmos. NO. Too deep to plant them like this...they will rot. However, I do pot on a little deeper every time. I repot several times from 9 cm to 2 litre pots. Every time too I pinch out the tips to produce very strong, sturdy bushy plants. I eventually plant out in June and have impact making plants then.
Currently my cosmos are in 1 litre pots...as soon as I see roots at the bottom of the pots I pot on. At this coldish time spare the watering too
