There are a few deficiencies that hedges in the United Kingdom UK are prone to. One of these rare deficiencies is known as the buxus potash deficiency. As we all know, fruit and vegetables suffer from the effects of nutrient deficiencies quite regularly and it is quite rare for well-established hedge plants to experience any type of nutrient deficiency. If your hedge starts to show signs of the nutrient deficiencies that are described below, the reasons why it is experiencing this nutrient deficiency is probably because your hedge or hedge plant or hedging was recently planted in a soil with the incorrect level of pH. Additional reasons leading to these deficiencies is that your hedge plants received either too much or too little water and or were exposed to too little or too much shade. Detailed below is a list of the most nutrient deficiencies that your hedges or hedge plants can suffer from in the United Kingdom including deficiency symptoms and actions to take to stop the growth of these deficiencies.
Nitrogen deficiency. Nitrogen is highly soluble so it can easily filter away. Your hedge, hedges, hedging or hedge plants will show signs of this nitrogen deficiency by developing yellow foliage, possibly tinged with pink and or weak gangly growth. To stop this deficiency you need to apply a high nitrogen fertiliser such as poultry manure or sulphate of ammonia. For a long term solution apply good quality organic mulch. Potassium deficiency. Potassium allows plants to control water absorption and to photosynthesise effectively. It is easily washed away on chalky and sandy soils. Your hedge, hedges, hedging or hedge plants will show signs of this potassium deficiency by developing leaves that show or grow tiny yellow, purple or brown edges. When this deficiency strikes flowering and or growing of fruit is not possible. To stop this deficiency you need to apply a high potassium (K) fertiliser. Sulphate of potash or proprietary tomato feeds are also an ideal solution.
Phosphorus deficiency. A Phosphorus deficiency is rare and is usually limited to clay soils in areas where heavy rains are prevalent. Your hedge, hedges, hedging or hedge plants will show signs of this phosphorus deficiency by developing foliage dulls. Your hedge turns yellow and its growth slows down. To stop this deficiency you need to apply a high phosphate fertiliser such as bone meal. Magnesium deficiency. Hedging plants are usually not susceptible to a magnesium deficiency. However, the two most common causes are the over-application of high potassium fertilisers and drainage in sandy soils. Your hedge, hedges, hedging or hedge plants will show signs of this magnesium deficiency when the foliage turns yellow between the veins and this deterioration is sometimes accompanied with a reddish brown tinting and early leaf drop. To stop this deficiency you need to spray Epsom salts every two weeks during the summer months. Other deficiencies. The three important trace elements that hedging plants hardly ever experience deficiencies in are molybdenum, boron and manganese.
