If you bring the hawthorn into the garden, you have to differentiate between outdoor and container plants when caring for them. There is a lot to consider here.

Hawthorn (Crataegus laevigata) is native to our latitudes as a dense, compact shrub or tree, but it also occurs in northern Africa. There we find the plant overgrown on the edge of the forest or in bushes. This suggests a relatively low need for water and nutrients. In order to be able to estimate the nutrient requirements, it is always helpful to consider the natural conditions of the plant. What you should pay attention to when plant care, we explain you in more detail below.

How to properly pour the hawthorn

❍ Hawthorn outdoors:

When planting hawthorn outdoors, you should not neglect watering in the first years of standing. After all, young plants do not yet have sufficiently developed roots to provide themselves with sufficient water and nutrients from the soil.

Older plants, on the other hand, do quite well without regular watering. The reason for this is the roots, which reach deep into the soil and ensure the absorption of water and nutrients. Therefore, irrigation in winter is not necessary. Nevertheless, it is advisable to support the hawthorn from time to time with watering, especially in hot summers and during long dry periods, because the plants prefer a rather moist substrate. You should definitely avoid waterlogging.

What can you do to prevent waterlogging?
It is not always easy to water the hawthorn properly, because an excess of irrigation water can quickly lead to waterlogging and thus damage the plant. If the roots remain wet for a long period of time, the plant will start to rot and can often not be saved. However, this can be prevented by watering the plant moderately but regularly. The nature of the soil is also decisive whether there is a susceptibility to waterlogging. A loose and well-drained soil can ensure that the water drains away instead of damming up.

Tip:
The permeability of the soil can be improved by adding coarse gravel or sand.

❍ Hawthorn in the bucket:

If the hawthorn is in the bucket, its demands automatically increase. The deep roots are restricted by the narrow vessel and cannot, as usual, extend their tap roots more than half a meter deep into the earth to supply themselves with water and nutrients. So you have to help and water the container plants always sufficiently. Especially in summer. Then you should water the tub plants regularly. Even in winter, the soil must not dry out completely, since then the roots can no longer supply themselves with nutrients. The substrate should always feel slightly damp.

The risk of waterlogging increases in the bucket. Therefore, do not miss creating a drainage before planting. For this, pottery shards or pebbles are placed in the bottom of the pot. When choosing the planter, you must also ensure that there are sufficient holes in the bottom of the pot so that the water does not build up. If you place the plant in a coaster, you have to check it more often, because here too irrigation water can build up, which ultimately leads to root rot.

Container plants should also be kept in mind in winter. You need winter protection or hibernate frost-free in the house. The floor must not dry out. Therefore, the hawthorn in the bucket should be watered sparingly even in winter.

Watering hawthorn as a field and container plant: the advantages and disadvantages

❍ Hawthorn outdoors:

+ Outdoor plants need less water.
+ Older plants can use their tap roots to provide them with nutrients.
- Water should be watered regularly in the event of drought.
- There is a risk of waterlogging.

❍ Hawthorn in the bucket:

+ The amount poured can be dosed well.
+ The floor is easy to control.
+ With a drainage, waterlogging can be prevented.
- The risk of waterlogging is increased.
- There is a limited supply of water and nutrients in the bucket.

How to properly fertilize the hawthorn

❍ Hawthorn outdoors:

Whether and how often fertilization is required depends on the quality of the soil. If we consider the demands of the plant, hawthorn can also cope with normal garden soil. In a rather barren location, it is advisable to upgrade the soil accordingly when planting. The addition of compost creates a substrate that is rich in nutrients and usually supplies the plant well in the first year of standing. If you continue to administer compost regularly in spring and autumn, the hawthorn does not need any further fertilizer.

If the soil is already sufficiently supplied with nutrients, you should rather refrain from fertilizing. On the other hand, during the growth phase, you can administer rose fertilizer in a weak concentration.

Tip:
Do not fertilize indiscriminately, but have the nutrient content of the substrate checked, because over-fertilized soil does not get the plants. A balanced ratio between nitrogen and phosphorus is particularly important.

❍ Hawthorn in the bucket:

The nutritional requirements of container plants are usually high. You should definitely use a nutrient-rich substrate. Play it safe if you use rose soil or special potting soil. Garden soil should be mixed with compost.

In spring and summer you can fertilize the hawthorn in a bucket with rose fertilizer. This happens until the flowers form. If the substrate contains little nutrients, fertilizer can also be added after flowering.
