Slugs they love petunias it must be like chocolate to them I do a night hunt every night.

Look underneath pots and seed trays ... slugs and snails 🐌 hide there during the day and come out to eat at night ... especially check under the rims of seed trays and in the spaces between the bases of modules ... sneaky little b*****s 😡
