A diluted neem oil spray repels insects and smothers those that come into contact ...
Whitewash, calcimine, kalsomine, calsomine, asbestis or lime paint is a type of paint made from slaked lime (calcium hydroxide, Ca(OH) 2) or chalk (calcium carbonate, CaCO 3), sometimes known as "whiting". Various other additives are sometimes used.

While the perceived risk of death by falling trees (a part of the "tree risk" complex) is influenced by media and often hyped (the objective risk has been reported to be close to 1 : 10.000.000, almost as low as death by lightning), [6] singular events have encouraged a "proactive" stance so that even lightly damaged trees are likely to be removed in urban and public traffic surroundings.

Pollarding tends to make trees live longer by maintaining them in a partially juvenile state and by reducing the weight and windage of the top part of the tree. [6] Older pollards often become hollow, so it can be difficult to determine age accurately. Pollards tend to grow slowly, with denser growth-rings in the years immediately after cutting.
