leaves on citrus
leaves of my potted lemon tree are yellowing. What do you think
could be causing this?
of citrus trees is often caused by lack of water, a general lack
of nutrients or sometimes, more specifically, magnesium deficiency.
For a lemon tree in a
pot, the best approach is to feed regularly with a liquid fertiliser
such as Thrive or Nitrosol throughout the growing season and in
both spring and autumn feed with a slow release fertiliser such
as Osmocote or Plantacote. Sprinkle the fertiliser granules on to
the surface of the mix or poke holes with a stick into the mix and
pour a few granules into each hole.
Just in case magnesium
deficiency is the problem, you could try spraying with a solution
of magnesium sulphate (Epsom salts). Dissolve 20g in a litre of
water, add a drop of dishwashing liquid and spray all the foliage.
