I just bought a 6" Citrus plant from lidl. it has 3 lime looking fruits on it.
Just seen on the label its indoors
Can i plant outside in the ground veg patch.
At only 6 inches tall I would not plant such a plant out into the ground. Young plants are always more tender than usual. Keep them in the pot and maybe place them outside somewhere with a warm wall through the summer months. Definitely bring indoors in autumn and keep in a cool area to over-winter.
