When you’re growing in your greenhouse it’s important to take precautions to reduce the chance of soil borne diseases. You can do this by digging out the soil in your greenhouse borders every few years and replacing it with good quality topsoil. Plants such as the tomato plant are good for problem areas. If you suspect your soil is diminishing, you can introduce grow bags and large pots. Cover your soil with plastic sheeting for additional protection and re-use your grow bags for different crops each year.
It’s so important that you don’t leave your greenhouse empty all autumn, really make the use of the extended growing season, producing some beautiful autumnal plants and vegetables for you to enjoy. Your unheated greenhouse will keep overnight temperatures as much as 5 degrees warmer than the outside temperature, providing a warm, frost-free environments for your plants. A dry plant is much less likely to freeze than a damp one providing much more protection from the harsh cold weather outside. The fluctuations in dryness and wetness throughout the cooler months are detrimental to your plants health and chance of thriving and surviving, making a greenhouse allow for contributing massively towards a consistent condition to grow in.
Here are some tips and tricks for cold weather growing:
- Be patient, you can sow many plants and vegetables in autumn and winter but they are largely slow growing
- Keep out the frost, Jack frost is not welcome here and will be detrimental to your plant health, consider addition insulation such as bubble wrap on the inside of your greenhouse
- Choose a variety of plants, by choosing a variety of plants you will be sowing and harvesting all throughout the cooler months, you can have faster growing plants such as salad leaves and herbs
- Getting ahead, by getting ahead you are preparing your greenhouse for spring and summer blooms, planting bulbs early means you will be graced with beautiful colours for the early spring
- If you can, buy a greenhouse heater, you will have so many more options to grow throughout the autumn and winter, not to mention a faster growing speed!
