This can happen even if there is plenty of nutrition in the soil!įor more information, check out this chart from Research Gate showing the relationship between soil pH and nutrient availability. If soil pH is too high or too low in your garden, it will prevent plants from absorbing nutrients through their roots. Slow Tomato Growth Due To Poor Soil ConditionsĮven with proper watering, soil drainage, and temperatures, tomatoes can still be finicky about growing if the soil conditions are not just right.Īn improper pH, lack of nutrients, or even excessive nutrients can all cause problems for tomato plants, leading to slower growth. If the weather gets really hot and dry, make sure to water your plants more frequently as needed. A piece of shade cloth can lower the temperature for plants by 10 degrees Fahrenheit or more.
You can also try using shade cloth to protect tomato plants from the hottest sun at midday. It will also prevent temperature fluctuations by insulating the soil. This will help to retain water by preventing evaporation due to heat and sunlight. Wood mulch will help to retain moisture and insulate the soil. To avoid over watering your tomato plants, make sure to workĬheck the weather forecast every day for any chance of rain.

When soil stays moist for too long, it leaves no room for air, and the plant’s roots cannot breathe. It may be even more common than under watering, since many beginner gardeners “do in their plants with kindness!” Over watering is one of the most common causes of slow growth in both young and established tomato plants. Dry soil that drains too fast can leave your tomato plants without enough water.
