To start with, it’s advisable to keep your greenhouse locked when not in use, especially in households with young children. Many potentially dangerous items are often kept in a greenhouse, like gardening tools and pesticides, etc. so it's important to keep them out of harm's way.
A greenhouse is designed so that it can retain heat and light, creating the ideal environment for plant growth. One of the keys to maintaining this environment is good ventilation, otherwise, air will become stagnant and humid which will allow fungi to grow. A lack of ventilation will also cause the greenhouse to become too hot and this will kill plants.
In the winter months, it is usually necessary to provide extra heat in a greenhouse by way of an electric heater. To minimize the risk of fire it is very important to only use a heater that is intended for greenhouses. You also want to keep this in mind when using other electrical items by only using those that are suitable for outdoor use. Keep them unplugged when you are not using them.
It is not uncommon for the greenhouse to develop a leak from time to time. If you notice a leak, fix it immediately to prevent too much moisture from accumulating and to stop mold or other pathogens from growing. Doing this will also keep insects away.
It's clear to see the need for regular greenhouse maintenance so that it is a safe environment for plants to flourish.
