Soil and fertilizer for outdoor plants
Good soil and fertilizer are important for healthy, fresh and beautiful plants throughout the season – regardless of whether you plant directly in the garden or in outdoor pots, planters, and boxes.
Although many outdoor plants can thrive in the same type of soil, there are plants that need specialized soil to reach their full potential. Different plants also have different nutritional needs, some require a lot, while others do best with little.
New garden plants – best soil and fertilizer
Below, we list the soil types we recommend for planting various types of plants outdoors in the garden. Further down in the article, you'll find tips for outdoor plants in pots, planters, and boxes – as there is a slight difference between planting in the ground and in a pot.
Mix cow manure compost into the soil when planting in the garden, so that the plants have access to nutrients for a good while, and preferably cover the soil surface with mulch or decorative bark – this helps to keep weeds away and allows the soil to retain moisture longer.
Plant new trees, shrubs and perennials
You can plant trees and shrubs for a large part of the year, except when the ground is frozen. If you can dig, you can plant! The slightly smaller plants, such as perennials, are best planted in autumn or spring. If you want to plant during the warmest weeks in the middle of summer, you have to be prepared to water a lot.

Plant new acidic soil plants
Acidic soil plants, such as rhododendron, blueberry, azalea, magnolia and hydrangea, prefer soil with a lower pH value and therefore need special soil.

Flowering plants
- Rose fertilizer can be used for all types of flowering plants, and is particularly well-suited for roses, perennials, and climbing plants such as clematis.
Bulb plants
- Bone meal promotes root and flower development for bulb plants like crocuses, daffodils, and snowdrops. It's best to apply bone meal before flowering in early spring, as soon as the leaves emerge. To prepare the bulbs for next spring, you can give a dose of bone meal after flowering.
Grass lawn
The lawn is an important part of most gardens, and sometimes it needs a little help. Think about the lawn and do something with it already in early spring, so it has the best conditions to become a beautiful lawn throughout the season.
- Fertilize the lawn with Trim lawn fertilizer, Plantasjen's lawn fertilizer or chicken manure.
- Top dressing helps to make the lawn denser, healthier, greener and more durable. Top dressing also loosens compact soil and reduces problems with weeds and moss.
- Lime increases the pH value and can give a tired lawn new life. If you are unsure whether you should lime, you can test the pH value with a simple home test. If the pH value is below 5.5, you should lime with garden lime.
- Moss in the lawn can be combated with moss remover, and to make the lawn robust and resistant to moss, premium lawn fertilizer is a good choice.
- Weeds in the lawn, such as dandelions, can be counteracted with lawn cleaner against weeds, but here you should wait until summer before you start.
Outdoor plants in pots and boxes – best soil and fertilizer
Outdoor plants in pots are limited to the soil, water, and nutrients available in the pot. Therefore, it is extra important to have good soil in pots, planters, and boxes. The amount of soil and space for the roots also play a role, so choose a large pot. Last but not least, the pot must have holes in the bottom so that excess water can drain out. See our tips for successful planting in pots.
