Think it depends on the variety tbh & how old the plants are, you might find that if you chop everything off, they might give you a smaller 2nd crop. Were they new plants this year & if so when did you plant them?
Just as an aside I bought plants from Lidl 3 or 4 years back 6 for £2.99 I think they were x 4 varieties & was they have been fantastic plants & beautiful fruits. I would certainly recommend them if they come up for sale again. I planted them in late spring shortly after buying them ( haven’t seen them this year but I don’t go quite as often so may of missed them) & I assiduously removed all flowers that year & it really paid off as they’ve made big plants. 1 variety was korona & 1 Osaka I believe & another was I think Elsanta. I’ve got it written down somewhere.
