Toilet paper tubes are biodegradable and inexpensive, making them a great option for seedling pots at home. However, they are prone to getting moldy quickly. But before giving up on using them, it’s important to know that mold can be prevented — starting with avoiding overwatering.
Seedlings growing in toilet paper tubes require less frequent watering than usual. The cardboard material retains moisture, leading to overwatering and creating ideal conditions for mold growth. To prevent this, water the seedlings at the base multiple times a week by placing the tubes on a flat surface with water underneath for the roots to absorb.
Allowing the tubes to have good air circulation is also crucial in preventing mold. Avoid covering the seedlings with plastic domes and instead let them have access to fresh air. Mold dislikes moving air, so keeping a window open can help prevent mold growth while promoting seedling growth.
Mold-free starts before you sow
Before sowing your seeds, ensure the toilet paper rolls are completely dry to prevent mold. Let them dry out on a sunny windowsill for a few days before planting any seeds. Cutting the bottoms of the tubes and leaving them open while planting allows for better drainage, reducing the risk of mold formation.
Additionally, using a light seed-starting mix with good drainage is essential to keep the soil from becoming too moist. Heavy soil retains water, increasing the chances of mold growth. Keeping the soil dry and the environment well-aerated will help prevent mold from appearing on your seedlings.
In conclusion, maintaining dry soil and good airflow will prevent mold from affecting your seedlings. When transitioning them outdoors, ensure a gradual process to avoid shocking the roots. Taking these steps will help ensure your seedlings remain healthy and mold-free throughout their growth.
