the first symptoms of magnesium deficiency show up as yellowing, usually between the veins of the older leaves. In severe deficiencies, the entire leaf will turn yellow or red and then brown, with symptoms progressing up the plant.

There are numerous plants that show this tendency, citrus, Daphne, rhododendrons, tomatoes, passion fruit and roses to name a few.

Once the yellowing starts to appear then already the plant is having problems and even when magnesium is supplied, it takes several weeks before the lovely dark green colour is restored.

During this time the plant is weakened, as the chlorophyll is not working to its full potential which makes the plant more susceptible to diseases and pests.

The amount of energy created from sun light is affected and plant growth is reduced.

During drought conditions, plants suffer and one important aspect to assist in this is Potassium.

It regulates water absorption and retention, influences the uptake of some nutrients and helps to increase disease resistance.

As the weather cools and winter approaches, plants feel the chill like we do, but plants cant put on a jersey like we can.

The plant’s protection from chills and frosts comes from having adequate Potassium in their diet.

Thus us gardening commentators always suggest to gardeners to supply potash to their plants as winter starts to approach and to avoid using nitrogen fertilisers which only increases sappy growth.

Commercial growers of plants and orchardists use the two elements to ensure their plants have sufficient Potassium and magnesium in their diet.

These two vital elements are blended together in the right balance as required for plants.

For the home gardener we supply Fruit and Flower Power in three pack sizes. 1.25 Kilos, and 2.5 kilos and a bulk bag which is 12.5 kilos making it the best purchase if you have storage room.

The 1.25 kilos comes nicely packaged in a stand up pouch with a 50 gram (50ml) scoop.

It is used at the rate initial rate of 50 grams (one scoop, just below level full) per square metre around the base of the plant or around the drip line.

Use for any plant that is flowering, fruiting, showing lack of vigor or yellowing in foliage.

Now this next bit might surprise many; but the monthly requirement is 25 grams (half scoop) per square metre.

This should be applied while plants are flowering, fruiting, during dry times and going into winter. Outside of these times a 2-3 monthly dose should be fine. For fruiting a dose at 50 grams should be applied prior to flowering followed by the 25 grams till harvest. For the likes of tomatoes and cucumbers, apply over fruiting period for best flavor.

I get a lot of complaints that citrus fruit are dry and lack flavor so this

A number of fertilisers mixes do not contain sufficient potassium, likely because it is a more expensive element which is a pity as it should be at least ample for general gardening use.

Now is a good time to apply Fruit and Flower power around your gardens and repeat each month with a small sprinkling. It will help to keep your leaves green and the plants will gain more energy from the sun even considering its shorter day lights hours as we head into winter. It will firm up sappy growth from summer feeding of fertilisers and plant foods. Also other precautions you should take going into winter include: Protecting your vulnerable plants from frost by using the Spray on Frost Protection; Vaporgard. Mulches used to overcome dry conditions in summer should be removed from under plants to allow the soil to breath and dry out quicker during wet periods.

This helps prevent root rots and loss of valuable plants.

A spray of Perkfection over plants that could be affected with wet soil is a good help to prevent root damage through wet feet. Spray vegetables and preferred plants with Magic Botanic Liquid (MBL) each week. (It helps them grow healthier and faster. Side dress vegetable plants with a sprinkling of BioPhos. Brassicas (Cabbage etc) that have caterpillars should be sprayed with Wallys Super Neem Tree Oil with Raingard added to prevent the oil washing off with watering or rain. Reduce the amount of water you are giving container plants indoors and tender plants in glasshouses. They do not need so much water now and wet feet intensifies the cold and can be fatal.
