General Information

Ideally test your soil with a kit to find out the pH and Nitrogen, Phosphorous and Potassium levels, this will help you to decide  which fertilisers/ soil conditioners to use/you need. 

 Plants perform best when they are getting the optimum amount of sunlight, appropriate amounts of water and plenty of essential nutrients for good growth and production of flowers and fruit. Optimize plant growth by knowing how and when to fertilize.

Fertilisers provide the nutrients needed by plants to grow, form flowers and healthy foliage, produce more fruit, establish a strong root system and fight diseases and insect pressures. Plants benefit from fertiliser applications most when they are in their peak growth, and spring is one of those times!

The best time to fertilize is when many plants come out of dormancy in the springtime. In spring, deciduous plants leaf out, flowering plant buds begin to burst, stems and branches elongate and new roots are formed. Nutrients will aid in all of this growth, so the rule of thumb is to make an annual application of fertiliser in the early spring.

There are several ways to fertilize plants, including slow-release granular fertilisers, liquid feed applied to soil as a drench, foliar sprays and fertiliser stakes. In addition, using natural fertilisers such as compost can add nutrients to your soil.

Compost is decayed organic material from other plant materials and animal waste from livestock that has a diet mostly made up from plants. Those include chickens, cows and horses. 

Compost also can be made from waste such as grass clippings and fallen leaves, in addition to kitchen scraps such as coffee grounds, eggshells and fruit and vegetable peelings. Worm castings and mushroom composts are two additional composts that add nutrients to your soil.

Plants can have individual needs when it comes to fertilisers. Acid-loving plants such as azaleas, blueberries, camellias, hydrangeas and rhododendrons prefer more of an acidic soil pH to take up optimal nutrients. Flowering plants need more phosphorus to help stimulate stronger bud, fruit and flower development.

Vegetable plants benefit and require more frequent fertiliser applications throughout the season because they are producing and that makes them heavy feeders. Slow-release fertilisers can be incorporated at planting time for extended nutrient release.  Additionally, some growers utilise liquid fertilisers every other week.

Applying fertilizer in the wrong season can cause increased tender new growth that can be damaged, especially if applied in cold weather in late autumn or in winter. So it is best to stop fertilizing during dormant seasons. Additionally, in zones that can be in danger of a late freeze, it’s best to wait until mid-spring. Everyone could benefit from putting fertilizer application schedules in their calendars.

Some general rules to follow when fertilizing:

Avoid fertilizing new plants until they are fully established, because it can cause an increase in tender new growth that can make the plant weak and leggy.
Always follow the manufacturers recommended rates and application methods.
Fertilize outdoor plants in the coolest part of the day, such as early morning or late evening, especially in hot summer weather.
Always water in fertilizers well to distribute nutrients throughout the soil profile and to prevent burning.
Lastly, avoid excessive fertilizing and perform soil tests annually to see what nutrients your plants need.

With all fertilisers use gloves and wash your hands after use.
