Narrowing the gold field - This is how you put the plant in your place


The Goldfelberich does not need optimal conditions to grow expansively. If you don't put him in his place in time, you'll soon have a huge sea of ​​golden rhubarb stems.

Many plants need years to decades to become large and expansive. In the case of the golden loosestrife (Lysimachia punctata) it is the opposite. It grows and grows and grows and thus gives even inexperienced plant friends unexpected gardening happiness. Once planted, the gold field is unstoppable. The small perennial quickly becomes a lush bush that takes over the bed and often continues to grow.

This happens less to the delight of the hobby gardener and a solution is sought to prevent the plant from spreading uncontrollably.

How can you limit the growth of the golden rocket?

The best way not to be surprised by a sea of ​​goldfinch stems one day is to keep an eye on the plant. In the first two years of standing, the joy of growth will still be limited. To keep it that way, the plants should be dug out and transplanted no later than the third year. The old earth is removed and the roots are shortened accordingly.

Transplanting Goldfelberich - explained step by step

❶ Carefully dig out the plant
❷ Remove old earth from the root ball
❸ Select new location
❹ Dig out the planting hole twice the width and depth of the root ball
Einsetzen Carefully insert the plant
❻ Close the planting hole
Ießen Water the plant well

The best time for this measure is spring. The advantages of transplanting are obvious:

  • Prevention of unhindered spreading by dividing the root or shortening the root
  • Soil exchange ensures the nutrient supply to the plants and stimulates growth and flowering

Creating a root barrier - long-term protection

If you do not want to be constantly busy dividing and transplanting the golden field, it is important to think one step further when planting and to create a root barrier. This is easier than expected and ensures that the gold field can no longer spread uncontrollably.

What is root lock?

Root locks restrict the growth of plants. There are special products for this in the trade, but some hobby gardeners also help themselves and use things from the garden, such as Plastic tubs or remains of pond liner or roofing felt. This may promise success to a certain extent, but is not really successful in the long term with a plant that is as vigorous as the golden field oak.

" Tip: Play it safe and use the root locks available on the market. These are available in roll form and can be brought to the appropriate dimensions. Thanks to their material properties, these root locks offer reliable protection.

What should a root barrier be like?

So that the root barrier fulfills its purpose, it should have some properties. Keep in mind that you want to keep your growth-loving Goldfelberich in check with the product for several years.

The following properties are advantageous:

  • stable and resistant
  • resistant to frost or sunlight
  • stable enough to keep mice, rats or moles out
  • environmentally friendly and as free as possible from pollutants

Root barriers made of high-pressure polyethylene (short: HDPE) are the best choice, since they are very robust and cannot be pierced by the plant roots (e.g. available here).

Install root barrier - Here's how

❶ Get root lock
❷ Limit the location of the plant
❸ Put the root barrier in the ground
❹ Close the root lock securely
❺ Root lock should protrude a few centimeters from the ground

Before the root barrier is attached, you should determine the area that you voluntarily allow the gold field to spread.

" Tip: Do not restrict the plant too much, the golden rocket oak needs a certain area for its spreading and formation of a bushy and compact growth.

The root barrier should protrude about half a meter into the ground. The resulting ring must be closed well so that the roots do not have any contact surface. The screwing of an aluminum rail on the ring of the root lock prevents it from drifting apart. The root barrier should also be visible above ground and protrude about ten centimeters from the ground. As a result, the plant is stopped above ground and no rhizomes can spread.

Too late? - Introduce root locks later

Have you planted your golden field and have you first observed its vigor when growing and are now faced with the question of how to limit the growth afterwards ?! The all-clear can be given here. Root locks can also be added later. However, at first you will probably spend some time removing all root runners that are outside the terrain that the plant intended. Once this has been done, the root barrier can be installed as just explained.

Root lock or implement - advantages and disadvantages

RealizeThe implementation of the Goldfelberich does not incur any additional costs. You gain additional plants. The soil does not need to be fertilized, as it is regularly replaced as part of the transplanting.Implementing the plants is quite complex and takes time. The implementation should take place regularly and be carried out at the latest in the third year.
root barrierA root barrier is installed directly during planting and is straightforward. Retrofitting is also possible. Commercial root locks are stable, robust and offer reliable protection.There are costs for the procurement of the root barrier. The introduction takes time and effort. In the event of incorrect assembly or if no branded product is used, root locks are not always reliable.
