Horticulture is Science and Art; Theory and Practice

To grow plants well you must understand both the theory, and the practical techniques used to put that theory into practice. There are thousands of different plants grown in our gardens; and we need to recognise that every species has it's own peculiar characteristics. Learning to identify different plants and understanding the science that underpins their growth, allows us to may appropriate decisions about how to treat different plants in different places and at different times.

You cannot simply do a weekend short course and expect to be a competent horticulturist, no more than you can do a short medical course and be a competent medical practitioner.

Feeding Plants

Anyone can buy some fertiliser and throw it on plants, but  proper plant feeding is more complicated than that.

If you put too much fertiliser, or use the wrong type of fertiliser; a plant may perform worse than it would if it had no fertiliser at all.

You need to understand, plants are often dormant in winter, and don't need any feeding at all. As they burst into spring growth though, they draw heavily on nutrients in the soil. This is when they need the extra nutrients a fertiliser can give.

If inadequate nutrients are present, plant growth becomes stunted. This effect is subtle and not usually noticed until it becomes severe. The nutrient level in the soil may drop as low as 30% below the optimum before deficiency symptoms such as discolouration appear in the leaves. By this time, the overall growth rate and general health of the plant has been affected significantly.

Choose the Right Fertiliser

There is a vast array of fertilisers available and every one is different. Using the wrong fertiliser or the right fertiliser at the wrong rate can create problems in your garden. So how do you choose the right one? For a start, it’s helpful to know what the various fertiliser terms mean:
Complete fertiliser – These contain a mixture of nitrogen, phosphorus and potassium. Some also contain calcium and sulphur, and trace elements. The formulations vary according to the plant groups for which they are designed, e.g. lawns, shrubs, azaleas and camellias. They come in powdered, granular and water-soluble form and are a convenient way to provide plants with all the nutrients they are likely to need.
NPK fertilisers – Another name for ‘complete’ fertilisers (Note: NPK stands for the chemical symbols: Nitrogen, Phosphorus and Potassium; which are the main nutrients a plant needs from a fertiliser).
Water-soluble fertilisers – These are powdered or liquid complete fertilisers that are applied as a dilute solution. They generally have a high nitrogen content and also contain trace elements. They are useful for boosting plant growth but only have a short-term effect.
Slow-release or controlled-release fertilisers – These complete fertilisers are designed to release their nutrients slowly, often up to 12 months. Some are in the form of plant pills, others are covered with a protective coating, eg. Osmocote and Nutricote. They are convenient, safe and easy to use but are more expensive than other NPK fertilisers. Some organic fertilisers such as blood and bone also release nutrients over a long period of time.
Inorganic fertilisers – Artificially-made fertilisers; includes the NPK mixtures.
Organic fertilisers – A broad term for naturally-occurring fertilisers; includes animal manure and animal by-products such as blood and bone, mushroom and other composts, green manures, seaweed and worm casts. The nutrient content is variable, depending on the source of the fertiliser. Some commercially prepared organic fertilisers have known levels of nutrients that are listed on the packet.

When you choose a fertiliser think about the following:

  • convenience and ease of use;
  • the type of plants you are fertilising and the time of year;
  • the soil type (clay soils hold fertilisers better than sandy soils);
  • how quickly you want the plants to grow;
  • how much you’re prepared to spend;
  • whether you prefer to rely on organic fertilisers.

Organic v. Inorganic Fertilisers – Which is better?

It makes no difference to the plants whether you apply artificial or organic fertilisers. They simply absorb whatever nutrients are available in the soil.

BUT there are important differences (e.g. the way they work; levels of pollution created in their production; residues on unused by products left behind, etc.).

  • Inorganic fertilisers release nutrients quickly, producing rapid plant growth.
  • Many inorganic fertilisers can burn plants if applied at high doses.
  • Many inorganic fertilisers have a short-term effect and need to be applied frequently to maintain growth.
  • Inorganic fertilisers can leave undesirable chemical residues in the soil.
  • Most organic fertilisers are safe to use and won’t burn the plants (except some fresh manures which should be aged before use).
  • Most organic fertilisers improve the texture and structure of the soil, thereby improving air and water uptake (exceptions are powdered organic fertilisers such as blood and bone).
  • Some organic fertilisers don’t contain many nutrients – their main value is as a soil-improver.
How Much Fertiliser Should You Apply?

It is always better to apply too little than too much. You can always add more, but you can't take it out of the soil and put it back in the bag.

Always read the instructions on fertiliser packets. If applying fertiliser to young plants or less hardy plants (e.g. ferns and some indoor plants) you are better to put on less fertiliser.
