All potted plants will eventually need repotting, or at least the existing soil is replaced with new fresh soil. Even when a plant stays about the same size, the roots are growing larger and thicker under the soil’s surface. Once the roots fill most of the space available in the soil and pot, the plant’s health will start declining unless the plant is repotted.
Sign# 1
One of the most common signs that a plant needs repotting is when the roots start growing through the drainage holes at the bottom of the planter. Also, when the roots start pushing up the soil and are clearly visible above the soil. This means that the roots do not have enough room to grow inside the pot.
Sign# 2
Another clear sign is when the water you pour over the soil drains out immediately through the drainage holes below the pot. This means that there isn’t enough soil to retain the water inside the pot, so it slips over the roots and out of the drainage holes as soon as it is poured in.
Sign# 3
You can also tell that it’s time to repot your plant when you see that the plant is at least three times larger than the pot, or the pot tends to fall over easily due to the heavy top foliage. Pots without enough soil usually don’t weigh much.
If you see that the health of your plant starts declining rapidly, check the soil. Plants that need repotting can start looking dull, lose many leaves, and get sick, simply because they can’t absorb the water and nutrients from the soil. Plants need the soil to retain a certain amount of water, so they can absorb the nutrients from it. Always remember that the root system is as important as the trunk, the branches, the leaves, the foliage, and the flowers that you love.
