Gardening

i don't pluck weeds from my flower pots on the balcony, because i want the environment for the flowers natural. the reason why i mention this is: you have to pluck trees while they are small saplings. they grow very strong roots. left unattended, they become very hard to remove and can even destroy flower pots. they are hard to spot sometimes. i had an oak in a pot and the first weeks it looked like a green mushroom with only two dark green shiny round leaves; nothing like an oak. when it grew the first actual oak leaves, the roots were already 30cm across the pot under various other flowers.
