Grow Bags for Tomato Plants

This post is about making the most of your grow bag or, "grow bag optimisation" to put it in a rather grand way!

Perhaps the biggest drawback with grow bags is that they can dry out quickly, especially when plants are fruiting. So here are a few suggestions to help keep the moisture in.

Make slits in the top of the grow bag and plant so that the plastic can be replaced around the bottom of the plant and the compost is not exposed and moisture is unable to evaporate.

Sink pots directly into the grow bag so that the plant roots can grow out of the bottom of the pot and into the grow bag (see above).

Add a few handfuls of perlite to the soil to aid water retention. Also, water retaining gel is a good option.

You will need to pierce drainage holes but make them at the ends of the bags rather than at the sides to help keep the entire compost area moist.

To help watering, sink a large pot in the middle which can be filled easily and the water can make its way out of the bottom of the pot (see pic. black pot between two Sungold plants).
