Their root system is restricted
July 28th, 2010Their root system is restricted to the pot so make sure you keep them well watered. Containers are far more likely to dry out in hot conditions which will kill your plants or have them ‘fruit’ poorly.
It is also very important that a mulch is put on top of the container. This will slow evaporation and keep the surface temperature of the soil cooler. Plants like tomatoes have small, fiberous roots which will dry and die in hot soil.
Container vegetables may need some additional fertilising due to the extra watering. Nutrients will be washed away quicker in a container than in the ground.
