Mulching Roses is justified for several reasons. But before we get into that, let’s take a closer look at what mulching is exactly and why it is of great significance, not only in rose cultivation. Roses are very popular flowers that adorn not only gardens but also parks and flower beds. This is understandable, as they are incredibly beautiful and fill their surroundings with a wonderful fragrance. To achieve this, it is necessary to care for them properly, and mulching – or soil covering – is part of that care.
The root system of different rose varieties develops quickly and is vulnerable to both drying out and freezing. The reason for this can be found in the fact that the roots are close to the soil surface, making them highly exposed to weather conditions. Therefore, mulching helps provide the proper conditions for their growth.
Mulching assists in:
- optimizing soil moisture and aeration
- regulating temperature
- weed control
- protecting roots from weather conditions
- retaining soil moisture
- guarding against pests and diseases
Choosing Mulching Materials
Perfectly suitable materials for soil covering include shredded bark, wood chips, straw, hay, and even fallen leaves. The advantage of organic plant mulch is that it improves soil condition as it decomposes. Furthermore, mulch protects the crops from splashing mud during irrigation, resulting in less soiling of the flowers.
Mulching can be done using a combination of different materials. Drier materials assist with aeration, while heavier ones provide better weather protection and help control weeds.
The ideal thickness is between 4-8 cm. However, it’s important to avoid an excessively thick layer of mulch, as it can hinder soil aeration. This can impede proper plant growth, leading to wilting or even complete destruction. If the layer is too thin, strong gusts of wind can scatter it away.
Any organic material can be suitable for this purpose. Examples include sawdust, moss, straw, freshly cut grass, compost, etc.
Peat – it increases soil acidity, so it is beneficial to use it in alkaline soils.
Manure – overripe manure reduces acidity, making it a good choice for low-pH soils.
Straw – provides good insulation, making it suitable for sudden nighttime frosts.
Freshly cut grass – enriches the soil with nitrogen.
By using mulch, the soil becomes less compacted, reducing the need for frequent loosening. Correct use of mulching can also reduce the time spent on plant care.
