You're on the right lines Frenchie - there is one undesirable (which could be desirable elsewhere) which is prevented by chalk, which, indirectly, has a very negative influence if allowed to roam freely.
A symbiotic relationship which often happens in fruit trees (though not exclusively there). Cut out one part of the equation and the other suffers - hence the thick chalk line, though there are other solutions.
Close enough Frenchie. Ants profit from the presence of Aphids (greenfly) and actually, herd, transport and protect them in return for the honeydew which they 'milk' from them - they will even transport aphids to other, more succulent, foliage - ants are, more or less, farmers in this respect. Where you have ants in a tree you are certain to have a largish aphid population there. Make it difficult for ants to get up your tree and the aphids are exposed to their natural predators eg. ladybirds, and their population will reduce rapidly. Protecting trees in this way is obviously easier than other smaller plants - where the aphid itself needs to be directly controlled. Chalk is very difficult for ants to actually cross over - in fact they often either fall off, retreat, or appear to have nervous spasms doing it. It doesn't even need to be special chalk - that intented for the old fashioned classroom will do.
Yes, it's worth a try Yorkie. You can actually get special chalk from a chemists for this, but the normal blackboard stuff works as well. It's not actually 100% secure against ants - after all we are talking about an insect which has survived since the time of the dinosaurs
That's the name Duggie. The name also sort of gives the reason. The rules were changed very early on and invalidated the name..
Was the name chosen because originally, the winners of previous season were only required to play a final against the winners of all the other teams who competed to get to the final ? hence a challenge to the team currently in possession of the trophy.
Which team has scored the most number of goals in the FA cup - since it began ? (The club has appeared in 121 FA cup campaigns)
Not a very exciting question obviously ! For starters, think of clubs more likely to have played more rounds, rather than clubs more likely to have gone the furthest.
