Planting Perennials


Learn how to plant your perennials effectively with our handy steps below...

1. A pot provides a strong root ball

The better the roots of a plant are developed, the faster the plant will grow, and strong sturdy root balls are created by growing young plants in pots. When you receive your purchase, leave the pot around the plant for a while. Do not remove the pot until just before you plant it. Water your plant regularly to keep it fresh and healthy.

2. When a pot is not needed

Not all plants need to be grown in a pot. Plants with a rhizome or thick, fleshy roots can go straight into the ground. Spread the roots wide in the planting hole, but be careful not to break them.

3. When to plant out into the ground

The planting times for a perennial is generally spring and autumn. The warm summer months are not suitable and planting in the freezing winter is absolutely 'forbidden'. Growing plants in pots makes the planting period much longer. However, for best results, it is recommended to plant in early spring or late autumn.

4. The correct planting distance

What is the correct planting distance between plants? It is difficult to give one answer for this. How fast a plant grows depends on the type of soil in which it is planted, but also on the location and the space that a plant has. Generally, 11 plants are needed per m². The distance between low plants is around 20 and 25 cm. Medium-high plants need a distance of 35 to 40 cm and larger, taller plants need a distance of 50 to 75 cm.

5. Placing the plants

Always start with plants in the back of the border and work forward from there so that you do not trample on the newly planted crops. Remove the plant carefully from the pot only just before it goes into the ground. Lift the plant by the root ball out of the growing pot. To promote regrowth, it is important that the roots are loose. Therefore, squeeze the root ball firmly a few times. Now you can place the plant in the planting hole you made in the ground. After planting, press the soil around the plant firmly. When all plants are in place, water sufficiently with the watering can or with a garden hose set on a gentle spray as a hard jet closes the ground. Make sure to water the plants daily for the first time.

6. Enjoy the beautiful flowers

In most perennials, the leaves and flower stems die in the autumn, but they bloom again in the spring. This applies to border plants as well as summer flowering bulbs. As perennials get older, they bloom with more flowers each year. In order to enjoy the floral splendor for as long as possible, it is important to always remove the dead flowers.

7. Care of your plant

Tall plants in particular need a little extra attention so use some branches or canes between the plants for support and divide the plants if they get too big. You do this by carefully removing the plant from the ground and dividing the root ball into pieces with a sharp spade or knife. After you have removed the dead roots and rotten plant parts, plant the divided sections separately in the soil. You will see the young plants start to grow again quickly. It is recommended to weed regularly, especially in the beginning. As the young plants grow, the weeds will also grow between them. After some time, the weeds hardly have a chance to develop because the plants start to grow towards each other.
