Productive Plot to Unproductive Plot

My most productive plot became the most unproductive in just a month! Sigh! Chillis not doing very well (discovered they are attacked by scales!), herbs not doing well either (parsley dying lah! apparently parsley doesn't like wet feet! But I can't control the weather god leh! LOL), killed off 1 of my roselle plants as it is infested too!..... Need to redo this plot again......
