Plants that can be a challenge to grow

Let’s look at some of the most difficult crops to grow.


Cauliflower plants often consume a lot of time and effort during planting. This is because you need to monitor them from time to time. Typically, cauliflower does not thrive in cool or hot temperatures.

The ideal temperature for cauliflower to grow well is below 75 degrees Fahrenheit. Thus, you have to ensure you sow the seeds and water before the first frost during the fall for best results.

Cauliflower crops are also susceptible to bugs and worms. So, do everything possible to keep these pests away. Consider using preventive pesticides and keeping the plants in good condition.

This plant also has to grow in soil with a pH of 6.5 to 6.8. Another reason why cauliflower is difficult to grow is that it takes a lot of work to keep the head of the plant in good condition.

The cauliflower head should be white; exposing this section to excess sunlight leads to discoloration. Therefore, you have to regulate the amount of light received by cauliflower plants.

Melons can grow up to 12 to 18 inches in height. Therefore, you need to have a big garden space if you want your melons to thrive. Another disadvantage of growing melons is that fluctuating temperatures can lead to bitter fruit.

When growing melons, you also need to water them constantly. Failure to do so might affect the quality of the melon fruits, affecting your sales and revenues if you are a commercial farmer.

Melon fruits usually grow well in dry regions and on sandy soils. So, if you live in the southwest region, consider growing this fruit.

Head Lettuce

The next most difficult crop to grow is head lettuce. Head lettuce is primarily affected by fluctuations in temperature. If the temperatures in your region tend to change from time to time, your head lettuce will taste sour or bitter.

Subsequently, you’ll have to use stronger pesticides frequently to keep them in good shape.
