Don’s Tips: Vegies & Nitrogen

By now your spring vegie garden should be well under way.  But you do need to know the tricks in getting both fast and reliable results.

In the early stages of growth all vegies are the same:  They need a quick nitrogen boost to get going.  So use chook poo or Aquasol or Thrive (or Powerfeed??): all get seedlings moving.

If you are growing leaf vegies like lettuce, silverbeet, spinach, kale or celery or herbs, you should keep these nitrogenous fertilisers up to them right until harvest time.

But if you are growing fruiting vegies like tomatoes, eggplants, chillies, capsicums, beans, peas, etc, you need to ease up on the nitrogen as soon as the plants are say, half grown.

The same applies to root crops like carrots, beetroot, parsnips etc.  Once they are growing well, you need to ease off on the nitrogen.  You can either fertilise very sparingly or cease fertilizing as long as they continue to grow well.

Over-fertilising fruiting or rooting vegies may prevent them from producing their fruits or roots.
