Even so, if you want to be safe, I will tell you that the recommended amount is the following:

  • Vegetables: between 20 and 30 tons per hectare.
  • Fruit trees: 10-20 liters per planting hole.
  • Ornamental plants and grass: the ratio 1: 5 of compost and soil is used; that is to say, one part of compost for five parts of soil. For example, we would put one square meter of compost for every five square meters of soil.

How is it used in pots?

It will depend on whether that manure is fresh, or whether it is dry. In pots, it is always very important to apply manures the drier they are the betterotherwise the roots would burn. Therefore, it is recommended to purchase it packaged (for example from here!), or let them dry in the sun for one or two weeks (more if it is autumn-winter).

As soon as it is ready, you have to mix it well with the earth. For this reason, we do not recommend its use in plants that are already planted in pots, but it is recommended when transplanting them to larger pots.

What plants is horse manure good for?

In general, being a compost of organic origin it can be really useful and beneficial for many types of plants: grass, palm trees, trees, flowers, orchard …
