Repotting plants correctly
Repotting plants is an essential part of plant care that is often underestimated. However, as with all gardening tasks, the right approach is crucial to success. In this guide, you’ll find out why and when you should repot your plants, how to prepare for it properly, and what steps you need to follow to give your plants a new home. Read on to find out everything you need to know and keep your plants in top condition!
An introduction to repotting plants
The importance and necessity of repotting
Repotting plants is not just a cosmetic procedure, but a necessary step for the well-being of your plants. Over time, space in the pot becomes limited and the supply of nutrients in the potting mix decreases. Repotting gives the plant more room for root growth and fresh soil, which provides important nutrients. This promotes the growth and health of your houseplants.
When and how often to repot
The best time to repot is in spring, when plants begin their growing season. Young plants should be repotted annually, whilst older plants can be repotted every two to three years, depending on their growth. It is important to take into account the needs of the specific plant species, as some plants are more sensitive to repotting than others.
Signs that a plant needs repotting
Typical signs that a plant needs repotting include vigorous root growth protruding from the drainage holes of the pot, the soil drying out quickly, and a slowdown in the plant’s growth. If the plant loses its stability and the pot tips over easily, it is time to consider a new, larger pot.
Preparing to repot
Choosing the right pot and potting mix
Choosing the right pot is crucial for successful repotting. The new pot should be just a few centimetres larger than the old one to provide the roots with enough space without leaving too much empty space, which could lead to waterlogging. Make sure the pot has drainage holes to prevent waterlogging. The potting mix should be tailored to the plant’s needs. You can find high-quality planters in various designs and compositions, suitable for every type of plant.
Tools and materials required
To repot, you’ll need a few basic tools and materials: a new pot, fresh potting compost, a garden trowel, a watering can and, if necessary, secateurs for trimming the roots. It’s helpful to use a mat to keep your work surface clean and prevent the compost from spilling. Prepare all the materials in advance to ensure the process runs smoothly.
Preparing the plant
Before you start repotting, you should water the plant thoroughly. This makes it easier to loosen the roots from the old pot. Gently tap the pot on a hard surface to loosen the soil. Take care to damage the roots as little as possible. If the plant is very dry, soak the root ball briefly in water to make it more pliable.
The repotting process step by step
Removing the plant from its old pot
To remove the plant from the old pot, hold the root ball with one hand and tilt the pot slightly. Carefully pull the plant out without damaging the roots. For heavily rooted plants, it may be helpful to cut open or break up the pot. Carefully remove the old soil from the roots to make room for the new growing medium.
Pruning and caring for the roots
Light pruning of the roots can stimulate root growth and remove diseased or damaged roots. Carefully trim the roots with clean secateurs. Take care to cut only the outermost roots and leave the main root system intact. This encourages the formation of new, healthy roots and improves nutrient uptake.
Placing the plant in the new pot
First, fill the new pot with a layer of fresh compost to create a base for the plant. Place the plant in the centre of the pot and fill in the gaps with compost. Press the compost down gently to stabilise the plant. Make sure the plant is not planted any deeper than before to prevent root rot. Finally, water the plant generously to allow the soil to settle.

Aftercare following repotting
Initial watering and fertiliser recommendations
After repotting, thorough watering is essential to settle the soil and prevent air pockets. Use lukewarm water and ensure that the water can drain away properly. You should avoid applying any additional fertiliser in the first few weeks after repotting, as the new soil usually contains sufficient nutrients. You can only start applying a light dose of fertiliser after about four to six weeks.
Choosing a location and the plant’s acclimatisation period
After repotting, plants need a period to acclimatise. Place the plant in a sheltered spot that is not exposed to direct sunlight. Avoid draughts and extreme temperature fluctuations. This acclimatisation period helps the plant get used to its new conditions and establish its roots in the new compost. After about two weeks, you can return the plant to its original location.
Common problems after repotting and their solutions
After repotting, a number of problems may arise, such as drooping leaves or stunted growth. These symptoms are often due to the stress caused by repotting and usually disappear after a few days. Make sure to water the plant regularly, but not excessively, and keep a close eye on it. If the problems persist, check the growing conditions and the quality of the potting mix.
Special cases and tips
Repotting delicate and large plants
Delicate plants and very large specimens require special care when repotting. With delicate plants, you should take particular care not to damage the roots. Use specialised potting mixes tailored to the plant’s needs. Large plants can be difficult to handle; it is advisable to ask a second person for help. Carefully place the plant in the new pot and ensure it is well stabilised to prevent damage.
Repotting during the growing and dormant seasons
Most plants should ideally be repotted during their growing season in spring. However, some plants can also be repotted during their dormant period in autumn, when they are less active. For tropical plants or succulents, repotting is often possible in summer too. Take note of your plants’ individual needs and choose the right time for repotting.
Use of special growing media and additives
Depending on the plant species, it may be advisable to use specialised growing media and additives. Cacti and succulents, for example, require a well-draining growing medium with a high sand content. Orchids thrive best in an airy mixture of bark and peat. Additionally, additives such as perlite or vermiculite can improve the structure of the soil and increase its water-holding capacity. Choose the right growing medium for your plants to create optimal growing conditions.
Summary
Repotting plants is an important step in promoting the health and growth of your houseplants. By choosing the right time and suitable materials, proceeding carefully and then looking after the plants properly, you can ensure that your plants thrive. Take into account the specific needs of each plant species and follow the aftercare instructions to avoid common problems. With these tips and tricks, you’ll be able to repot your plants successfully and give them a new home.
