We have a grapes tree in our garden. the grapes are at their peak now (if left on the tree they will begin to spoil) the grapes are salty like hell and not edible but perhaps can be used to make some jam or something else parents say trash them - no time to bother making the jam + dont know any friends who do either i see a problem with it - trashing them means trashing the minerals from our garden ground. won't it degrade the ground ability to grow stuff ? how to avoid it ? or does trashing them actually help remove excess salt from the ground ? (is the problem with the ground or with the tree itself ?)
