Fertilisers for Specific Plants

The needs of different plants will vary, so one fertilizer does not necessarily suit all.

Here are some tips on choosing the right type of fertilizer for your plants.

Azalea, Camellia & Rhododendron
These are lime hating plants, and as most fertilizers contain lime look for ericaceous fertilizers as they do not contain Lime, so are safe to use with plants like these.

Carnations
Beginning about eight weeks after transplanting the small plants to their permanent location, monthly applications of a commercially prepared fertilizer should be used, preferably the type which is dissolved in water and poured around the base of the plant.

Chrysanthemum
The regular use of a high Nitrogen and Potassium fertilizer will greatly increase flower size and numbers, We recommend incorporating a slow release fertilizer such as Osmocote at planting time plus a weekly feeding of a high analysis liquid fertilizer after August 1st and until flower buds show colour. Change to a 20-20-20 fertilizer, or no fertilizer, after this date.

Citrus Plants
Some plants, such as citrus plants, benefit from having a shot of fertilizer applied directly to their leaves. This is especially true if the plant is lacking iron, which is often indicated by yellow leaves with green veins. A foliar feeding is good during any period of rapid growth. You can find citrus labelled fertilizers in most garden centres, but if you don’t see any, pick a fertilizer that is low in nitrogen and has equal parts phosphorous and potassium. A 6-4-6 fertilizer is a good option, or a 7-3-3. Make sure it’s a good quality fertilizer complete with micronutrients. Follow the information on the fertilizer label for how often to apply it, but a good rule of thumb is to feed your citrus trees once a month until the weather cools and the growth begins to slow down. Then stop feeding, but give water when needed

Clematis
It is important to keep established clematis well fertilized or you will end up with smaller and fewer blooms. During the first year, use a water-soluble fertilizer two or three times early in the season. Once it has been in the ground a year, apply a fertilizer high in phosphorus in May, and again in mid-June. Always follow the directions on the fertilizer package. Clematis use lots of water and want the soil to stay consistently moist. In mid-summer, an established vine can use several gallons of water each day.

Fuchsia
A water soluble powder type balanced fertiliser is ideal. Never apply to dry soil, always make sure the soil is damp first and thoroughly mix the powder with the water.

Tomatoes
Let’s take a look at the ingredients that make up a good tomato fertiliser as well as some interesting homemade secrets that you may find helpful in boosting your tomato plants nutrition.

Certain necessities tomato plants need in order to grow to their fullest include calcium and magnesium. When people choose a standard NPK fertilizer many tend to overlook this but it is important you find one that has added calcium and magnesium or find an alternative method for giving these minerals to your tomato plant. NPK is the abbreviation for Nitrogen, Phosphorus, and Potassium, nutrients that all plants need. Usually, a plant would receive these elements through nutrient rich soil, but potted plants, or plants that have been grown in soil that is lacking in nutrition require fertilizer to provide these elements. The correct balance of these nutrients is important. One of the most highly recommended tomato fertilizer combinations is an NPK with a balance of 5-6-5 or 4-5-6. This is the percentage of each of the elements in the fertilizer, Nitrogen, Phosphorus and Potassium. This should be shown on the packaging.
