Where Does Good Horticulture Begin?

Anyone can grow plants. If you plant enough different plants in a garden, and wait long enough for them to grow, something will almost certainly grow.  This is really more "luck" than good horticulture though.

Good horticulture involves knowing what you are doing. When you actually know what you are doing, you don't waste money and time buying plants you might get to grow, just so you can stumble across one that does grow.

Growing plants usually starts with growing them in a pot; and then once they are big enough, moving them into the ground (or a bigger pot).

Success with growing anything in a pot, always depends upon having a good potting mix for it to grow in.

How to Evaluate a Potting Mix

When you look at a potting mix, you will see that it contains at least two materials, and sometimes more:

Bark – aged pine bark is a very common ingredient of potting mixes. Bark mixes are likely to drain well – perhaps too well for many plants. Mixes with lots of coarse bark ships are usually cheaper than other mixes. Finer bark chunks are preferable for most plants because they hold water better.

Sawdust – coarse, aged sawdust is used for aeration and water retention. It is an inexpensive material, and is often used in cheaper mixes.

Sand – coarse particles are often added to mixes to improve aeration and drainage. It adds stability and weight to the mix. A very sandy mix is likely to drain well and is best used for plants that prefer dry soil (e.g. cacti).

Vermiculite – a small, soft flaky mineral that is used to improve water retention.  Often used in more expensive mixes.

Perlite – sterile, porous white material used for water retention. Coarse perlite has better aeration than that with finer particles.  Often used in more expensive mixes.

Peat – when it’s moist it has a dark-coloured, spongy appearance. Peat is used to retain water in the mix but if it dries out the mix is difficult to re-wet. Mixes that contain peat are more expensive.

Soil – not commonly used in potting mixes but sometimes used by nurseries that bag their own mixes. A highly variable ingredient that should only be used in small quantities in the mix.
Other materials – mushroom compost, peanut shells, blend manures and other composted plant materials are sometimes included.

Fertiliser pellets – these appear as small round balls dispersed through the mix. These will release nutrients slowly to the plant roots – usually for up to 3-6 months.

Water-retaining crystals - are very often added to potting mixes which is ideal for those of us who don’t always remember or who are too busy to water the plants. These are small transparent pellets.

Different mixes are needed for different jobs

Indoor plants – humidity is a requirement of indoor plants.  Most indoor plant mixes will be high in materials that will retain moisture and promote humidity around the plants.

Baskets – these are prone to drying out so good basket mixes contain peat or other water-retentive material; also may contain water crystals

Outdoor pots, tubs planters – generally speaking, a multi-purpose potting mix will suffice for most plants.  Potting mixes are high in nutrients to compensate for the fact that the plants’ roots are contained in a pot.

Acid-lovers – Acid-loving plants such as Camellias, Heathers, Azaleas and Rhododendrons are best planted in an ericaceous (acidic) potting mix.  Whilst they will most likely survive in a multi-purpose mix they will grow more strongly and flower better in acid soil.  If you cannot acquire an acid mix you can make your mix more acid by adding a solution such as ‘Miracid’.  You can check the pH (level of acidity/alkalinity) of your potting mix with a simple soil testing kit available from your local nursery or garden centre.

Special mixes – There are a number of special mixes available for specific plant species such as Cacti and Orchids.    

Checklist

Take a checklist with you to the nursery. It could include the following points:

  • What plants do you need it for? Will one mix be suitable for all your plants or will you need different mixes for different plants?
  • What type of pots will you be using – plastic, terracotta, hanging basket?
  • Do you want a mix that contains fertiliser and water-retaining crystals?
  • Do they meet Potting Media Standards in your country (Only some countries have established standards?
  • How much are you prepared to spend? Top quality mixes cost more.

If you cannot find exactly what you require, you can always mix the available potting mixes or add ingredients to make your own special purpose mix.

What’s so special about potting mixes?

Good quality potting mixes are essential for growing plants in containers. They are designed to retain moisture but drain freely. They are clean and free of diseases and weeds. They are are relatively lightweight but have sufficient ballast to support the roots and aid good plant growth. Some mixes also contain fertiliser and water crystals to help establish your pot plants.

Knowing about potting soils is only a starting point -and there's a lot more to learn to properly understand just potting soils. This course is a really good place to develop that sort of in depth understanding though.

What do our Students Say?

"Thanks for the videos, they are great! I got a lot of information from them. The Turf Management video is practical and easy to understand. Plant Propagation is a video every student should watch because out here in the real world no-one would give out such information. The Rose Growing Tape was very beneficial to me as I have about 60 odd roses. I thought I knew a little about them but this tape is a real eye-opener."
