Well if you are swimming on the 23rd of December, why should the plants not be happy? Jonna, I wonder if he is walking around in a singlet, lucky you. Up North after a certain age we get a problem known as joints locking in winter. So, we are all huddled up against the fire and I can assure you, leave aside swimming even a bath is a difficult call to make.
Wonderful pictures and if the ants are taking pieces of leaf they are also providing protection. From you for one, see? These ants which you described are Asian in origin, check see.
Beautiful lady and her sparkling eyes tell me she is going to help you a lot even though the sparkle is for another reason. Two and a half acre, twenty kanals ideal size. Make a go at it and start a pictorial record, starting from how it looks like just now. There might be some salvageable plants in there.
