Given that knowing all the above off by heart would take a lot, my calendar below has taken out the hard work for you. with your very own what to plant when calendar.
Right click on the image, print it and pop it somewhere handy, so that the next time you’re not sure when to plant your tomatoes, you can refer to it.
As well as when to plant I’ve also included a handy guide as to which plants work best grown together and which don’t. Don’t forget though to always check the instructions on your seed packet or plant label and be aware of different temperatures in different parts of the country.
Please note: this calendar is a guide and does not consider regional weather variations.
