Pro Tips for Gardening in a Greenhouse

Your greenhouse requires regular maintenance to reduce agents that are harmful to plants.

Caring for Plants

If you want to keep your greenhouse sustainable and healthy, follow these tips:

Use quality potting soil that drains well; avoid mediums that hold much water. Otherwise, the roots will suffocate and plants will rot. Consider lightweight potting soil that lets roots access air.

Use a diluted fertilizer mixture until the seedlings have matured for a couple of weeks if you’re fertilizing seedlings.

Keep a clean house. Having a clean greenhouse can significantly reduce potential diseases and fungi that harm plants. Keep your gardening tools clean and consider pest control.

Inspect plants regularly. Check behind larger plants for any eggs and insects; look under the leaves and dispose of diseased plants. In the winter, when you bring your garden plants into the greenhouse, inspect each of them for insects and pests like slugs.


Greenhouse needs heat
While overheating should be avoided, greenhouses need plenty of heat to thrive. Installing a solar heater can help.

The Importance of Heat

Controlling the environment is important when you own a greenhouse. If you live in a cold climate, insulate your greenhouse to keep plants warm.

Even if the greenhouse receives plenty of sun during the day, it can easily become too cold inside at night. For this reason, use a gas- or electric-powered heating system to help control the climate.

Alternatively, consider a solar heater designed for a greenhouse. Consult a professional for a solar panel installation that matches your greenhouse’s needs.

Must-Have Garden Tools

If you live in a warm environment, where the sun can hit your greenhouse directly, consider shading. Use tarps or covers that reduce the amount of sunlight entering the greenhouse and prevent plants from burning.

You will also need a wandering wand to water hanging baskets or plants on shelves. It can be 24 inches long or more. The wand is also useful for watering plants on benches.

In addition, you need a pruner that fits comfortably in hand, and consider one with a hook at its end for easy hanging on the wall. Have a pruner for soft foliage and another for woody stems.

You will also need a bucket to transport dead plants or any material to the compost.
