Too often I see sad and sorry pot plants that are slow growing, blotchy, unproductive and hydrophobic. It is so important to have good soil wherever you go, in the yard, under the lawn, in beds or in pots.
I recommend repotting your plants once a year but you need to watch the signs in case they need it more regularly. A sure sign for me is slow or no new growth and water resistant soil.
To start off I mix up a bucket or a barrow full of soil. Some potting mix to start off, I don’t tend to splurge on this because I am adding plenty of food to it. Mix in about a third of the soil again in rotted manure, compost, worm castings. You can buy this or even better use some you’ve made yourself. I add a handful or two of all purpose slow release fertiliser, double of dynamic lifter. Soak the soil mix well will a seaweed or fish fertiliser.
While the existing pots are water repellent, I use a watering can to mix by hand gently scraping away the poor soil and digging out the potted plant. Once out, I gently shake off the poor soil from the root system. For a more established plant I used a strong spray from the hose to dislodge this. It’s important to get rid of this soil as if planted in to the new soil with this still attached to the roots the plant’s will not be able to take up nutrients.
When the plants are repotted I do not press the soil down firmly but rather let the soil settle with a gentle spray of water.
Now is a great time to replace potting soil and re position your pot’s at the same time with the changing weather.find sunny spots to relieve plants from frost.
By repotting you will certainly get much more from your plants, whether that be flowers or produce.
