line as well, but don’t mulch around the trunk of the tree to avoid collar rot.
If you’re growing citrus in containers, feed them now and in summer with a slow-release fertiliser, then give them an extra boost of TLC by applying a liquid fertiliser once a month. Refresh the potting mix in potted citrus every two years.
If you’ve just planted a new citrus tree and it’s flowering, remember that it’s a good idea – although requires an admirable amount of willpower – to take off the developing fruit in the tree’s first season so that it can develop a strong root structure. If you can’t bring yourself to do that, knowing that means no citrus next winter, compromise by removing at least half of the fruit.

TOMATO TO-DO LIST
If your tomatoes are flowering they need less nitrogen (for leaf growth) and more potassium for fruit set. Feed once a week with a liquid feed such as Daltons Controlled Release Tomato Fert or Yates Thrive Tomato Liquid Plant Food. Water well after feeding. Reduce to a fortnightly feed once fruit has formed.
If you haven’t staked your plants yet, do it now before they get too big and you damage the roots. Mine look a bit OTT right now under their tall stakes but I have expectations that they’ll achieve great heights of 1.5m at least!
