When you plant your tomatoes, it’s a good idea to plant them a little deeper than you normally would… the reason we do this is for a healthier, stronger plant.
If you look at your tomato plant before you pop it in the ground, at the base of the stem you will see the stem is slightly darker with lots of little hairs, and the odd bump here and there. All these things are its root system, which will come to life once in contact with the soil. So, by planting your tomatoes a bit deeper, you are enabling the plant to produce more roots. And more roots mean more water and nutrients.
So, how deep to plant? Well, if you strip off any lower leaves at the base of the plant, leaving the top most leaves intact, you can really plant it quite deep, leaving just the top leaves exposed. But any extra depth you give them will help, even if it’s just an inch or two.
