It’s possible I overwatered

[Suaz]

Thanks for your reply, Charles. Unfortunately, it’s hard to know what’s happening in adjacent plots as neighbours on either side are on semi-permanent vacation in the summer months (though looking over the fence I can spot some brown patches on the beetroot leaves next door)… I’ll see if I can talk to one of the other plotholders on our site. It’s also possible that I didn’t allow for the improved water-holding ability of my soil after a year and a half of adding both animal manure and compost, and ended up overwatering some crops. Last year the soil soaked up huge quantities of water, it’s possible that this year I needn’t have watered so much. In general, insects have been much more of a problem this year, from spittlebug on the spinach to greenfly and aphids on the outdoor tomatoes and chillies. About the only plants in radiant health appear to be the carrots and parsnips I’m growing under mesh. As regards the leafminers in particular, they appear to be doing most damage to the celeriac and the broccoli leaves. The broccoli appears to be growing strongly regardless, so I’m hopeful that it will outgrow the leaf-mining eventually, but the celeriac is looking sad after losing so many leaves. Yesterday I noticed ladybird larvae on the plot so I’m hoping that they may help although I don’t know if leafminers are part of their diet.
