Fertilize boxwood properly


The Content Of The Article:

Loose, calcareous and preferably slightly loamy soils as well as regular watering: boxwood is so unpretentious and easy to care that you often forget the fertilizer. But even if boxwood grows rather slowly and is not exactly one of the most hungry plants, it still needs regular fertilizer. Because only with the right nutrients, he can train his rich green leaves. If Buchs is hungry, he is protesting the lack of nitrogen with reddish to bronze-colored discolorations.

How can you fertilize boxwood?

Since boxwood does not produce any showy flowers, it does not need much phosphate, which is used to promote flowering. The evergreen plants are rich in fertilizer, a good dose of nitrogen and a good dose of potassium. This is important for the water balance and increases the frost hardness. Those who have many plants or a book hedge, therefore treat them to special boxwood or green plant fertilizer. These are available in liquid form as well as granulated slow-release fertilizers, which both contain a lot of nitrogen and potassium but little phosphorus. For green plants like the boxwood, phosphate would be pure luxury. Therefore, the well-known blue grain with its rapidly soluble nutrient supply is not the first choice for fertilization here. Although it works, but his potential remains largely unused in the slow-growing book.

Fertilize boxwood with horn shavings

Organic long-term fertilizers such as horn shavings or compost must be well incorporated

Mature compost or horn shavings, on the other hand, are good for fertilizing books. Make sure you use compost well - otherwise it will easily become a weed spreader as it often contains abundant seeds of composted weed. If you have composted only grass clippings or leaves or used a closed composter, weed is not a problem.

When should you fertilize Buchs?

Fertilize your boxwood only during the growing season from April to September. Long-term fertilizer supplies the book well for half a year, so you sprinkle him in the garden book or bush hedges at the beginning of April on the plant base and works him. From September you should generally stop fertilizing, otherwise suffers the frost hardness of the boxwood. The plants would still form soft shoots in autumn, which are no longer sufficiently frost-resistant before winter. The long-term fertilizer, however, is consumed until September.
The only exception in the fall is Kalimagnesia, a potassium fertilizer that is available in the country trade as Patent Kali. You can also give this at the end of August, it promotes the frost hardiness and acts as a kind of antifreeze, which quickly turns shoots and gives the leaves a firm cell structure.
