Over the seasons, some perennials can, while continuing to grow, give fewer flowers or even dry out in their center. Not to mention that a perennial that thrives can quickly annoy neighboring plants. It is then time to consider the division of its strain. It is possible, without endangering the plant, to separate it into several parts which will themselves become plants in their own right. The benefits are multiple: on the one hand you regenerate your plants, on the other hand, without paying a penny, you get several subjects to decorate your other beds. And why not make happy among the gardeners around you or feed a "barter-plants"? Difficulty : easy Cost : no Tools required : - A spade to divide large clumps - A pruning shears to remove faded parts - A disinfectant product

What is a perennial?

A perennial can live for several years unlike other so-called "annual" or "biennial" flowers. A perennial falls asleep in winter and regrows in spring. It can thus go through harsh winters and return every year for your enjoyment. Another characteristic of the perennial is that it is possible for its owner to "split" it into several pieces, which will themselves become real plants.

When to divide a perennial?

For those that bloom in late fall, the best time is usually in the spring, when the sap rises in the stems and the first shoots start to come out. It is the most favorable moment for such an operation: the perennial will recover quickly and will flower the same year of your intervention. For those which bloom in summer, a division in autumn allows the roots to better anchor themselves in the ground before winter and the first winter frosts.

Step 1: We disinfect our tools

In the living world, when you cut, you disinfect: this principle also applies to plants. It is not an obligation but certainly a good habit thanks to which one will avoid transmitting bacteria and parasites from one plant to another. A paper towel or cloth moistened with alcohol will do the trick to clean the blade of the tool, failing that, the flame of a lighter. Do not forget to wash your hands, because you too can be the vector of contamination (spores, bacteria ...).

Step 2: We define a circle around the plant

Using a spade, mark a circle around the plant: not too close to avoid damaging the roots, not too far to avoid extracting more soil than the plant.

Step 3: We take out the strain

After going around the specimen, here a blue flowered népéta, also called "catnip", push the spade well below and lever to remove the stump.

Step 4: We put the plant on the ground or on a table

Gently place the plant on the ground or on a table so that you can work comfortably.

Step 5: We slice in the middle of the root ball

It only remains to operate on the patient. Using a knife, slice in the middle of the root ball. There are many roots on this subject and do not pose any particular problem. You may have an inextricable jungle in front of you, in this case and to facilitate disentangling, dip the roots in a bucket of water to remove the soil and see more clearly. It will then be necessary to soak the roots previously exposed in mud (earth + water) before replanting.

Step 6: We divide the root ball

Divide the clod at your convenience, depending on its size and the number of subjects you want to draw.

Step 7: We replant the new subjects

Replant the new subjects immediately, or make them happy by offering them around you!

Step 8: We water

Water to promote good rooting of the plant. It's finish !
Two weeks later, our two twins flowered, a sign of their good health. Each new strain will develop, flower from April to the first frosts and each year the division can start again. The Nepeta, like many perennials, dries up in winter, but starts again in the spring. The dry stems will be cut. Divide and multiply irises Our practical gardening videos
