The fruit will remain on the vine longer than any other tomato because of the crack resistance. You can directly eat the Tomato from the vine or add it to your salad and vegetable dishes.

You can even make salsa or ketchup with these yummy tomatoes


Juliet Tomato Plant Care

Juliet Tomato plants need a nutrient-rich, airy soil medium containing 50% compost under direct full sun. Water it regularly while fertilizing with a fertilizer having 10-8-10 NPK ratio. Being a warm-weather plant, it requires 70 to 80 % levels of humidity. Temperatures should be around 70 degrees Fahrenheit (21 degrees Celsius).



Just like other tomatoes, Juliet must also be grown in a nutrient-rich, healthy, and airy soil medium. If you are cultivating in a bucket or container, the soil medium you use should be very rich in nutrients.

A 50:50 compost mix or a high-grade soil medium will be preferred for this purpose. 

You can invest in buying a rototiller as it will help in breaking your soil and allowing it to breathe. If you can’t afford to purchase it, you can use a shovel to break the soil conveniently.

The pH of your soil for growing Juliet Tomato needs to be between 6 to7. You can also prepare your own soil medium by adding some 10-10-10 fertilizer to the ground. 

However, after doing so, do not directly plant the tomatoes but rather water the soil and wait for 24 hours. 



To make your Juliet Tomato grow and produce good fruits, water it properly and regularly. Your Juliet needs water just like you need it to stay hydrated.

If you do not water your Tomato plant for a long time, it will reach a point where you will not be capable of reviving it, and it will ultimately die. 

Watering Juliet Tomato at the right time during the day should also be considered when planning to grow a healthy plant. 

When you water your plant during the extreme heat of the day, the water gets collected on the foliage. This, in turn, attracts the heat from the sun leading to yellowing and burning of the leaves. 

Water your Juliet tomatoes early in the morning, allowing the water to dry up during the rest of the day. 

Another option could be to water it in the evening but make sure you do not overwater the plant.



Your Juliet Tomato will enjoy a full exposure to the sun to thrive. The tomato needs a minimum of 6 hours of direct sun, but if you want better and faster results, provide it with 8 hours of direct sunlight.

Light is extremely important for your Juliet Tomato since it converts the light into energy to use it. This energy is then used to produce fruit. 

In short, the more sun you provide to the tomato, the more energy it will have, and ultimately it will produce more fruit.

If you are developing Juliet Tomatoes, outdoor sunlight won’t be an issue since the plant will receive direct sun throughout the day to grow. 

It is recommended to use some shade during the intense noon sun as the rays are intense and might burn your delicate tomatoes.

However, if growing the tomato indoor is the only choice you have, using artificial grow lights will be a good option. It will provide your Tomato the same amount of light that it receives while outdoors. 



Juliet Tomatoes are warm-season tomatoes, thus, it’s best to plant them when the last frost date has passed. 

The ideal temperature range for growing a healthy tomato is 60-70 degrees Fahrenheit (15-21 degrees Celsius).

During the germination period, provide the tomato with a temperature of about 59 degrees Fahrenheit (15 degrees Celsius). 

However, to grow faster and better, the fruit keeps the temperature between 68 to 75.2 degrees Fahrenheit (20 to 24 degrees Celsius).

Juliet Tomato can, at some level, adapt to nighttime temperatures falling up to 56.3 degrees Fahrenheit (13.5 degrees Celsius), but below this, it won’t produce any fruit. 

However, a daytime temperature going below 59 degrees Fahrenheit (15 degrees Celsius) for more than a week will pose problems like stunted and poor growth.

Hence be very cautious about the temperature around your Juliet Tomato. Anything out of its range and you will end up with poor fruit.



Just like other cherry tomatoes, your Juliet Tomato needs 80% to 90% of daytime humidity. During the night, they can survive in the humidity range from 65% to 75%.

To increase the humidity around your indoor Juliet Tomato, place a humidifier near it. Avoid placing the plant in dry and cold regions since it is a tropical plant.



Fertilize your Juliet Tomato during its active growing period for better development. 

To grow a healthy Juliet Tomato, apply a proper fertilizer at the right time and at a proper rate. The best fertilizer for the Tomato is the one that contains all the necessary macronutrients along with essential micronutrients like zinc, magnesium, and calcium.

The ideal NPK ratio for your tomato fertilizer should be 10-8-10. It has got just the appropriate amount of all the necessary nutrients your Juliet Tomato will need to prosper and produce nutritious fruit.

However, be very careful when applying fertilizer to the plant as overfertilizing and under-fertilizing both cause severe issues to it. Under fertilizing leads to stunted growth, inhibition of fruit, and diseases.

Giving the excess amount of nitrogen to your Tomato will cause yellow leaves. You will also face lower leaf wilting.



You must repot Juliet Tomato 6 weeks before the arrival of frost. Summer will be an ideal time.

For repotting, take your young plant and place it in a pot that contains a good amount of fertile soil. Water your Juliet tomato, and it’ll soon begin to adjust to the new place.



In order to increase the number and size of your Juliet Tomato, an easy trick is to prune it. 

Prune the Tomato on a regular basis to promote the bushy plant, keep it safe from disease, and eliminate the dead parts of the plant.

Start the pruning process by pinching the suckers. This will promote the production of healthier fruit on your plant. 

Being a vining plant, Juliet needs to be pruned now and then in order to keep it thriving and not to die of suffocation.

To keep your Juliet Tomato vine under control, do not forget to prune it when it outgrows the area. However, do not prune more than 1/3rd of the vine, or else there will be weak and stunted Tomatoes.

Thoroughly sterilize your pruning instruments and your hands to keep diseases away from your Juliet Tomato. 



An easy way of doubling your Juliet Tomato through propagation is by rooting the suckers from one of your mature Tomato plant.


Rooting Suckers

To start off this process, you first need to find a sucker on your Juliet Tomato. Carefully examine your plant from bottom to top, and you will surely find two branches that are forming a fork.

Close to this, find a third stem that must be coming out from the center of this fork. That new and tiny branch is called a sucker.

When you have identified the sucker on your plant, simply pinch it or cut it using clean pruning shears. A good size for a sucker is around 4 inches (10 cm). 

Leave two sets of leaves at the top and remove all the leaves from the lower end of the sucker.

Put the sucker in a jar filled with water and allow it to produce roots. It’ll take about a week for the Juliet tomato to produce new roots.

You can also insert the sucker directly into the soil medium and water it thoroughly.

When roots develop in water, transfer it to the ground and water it well until it establishes a good and strong root system.

Your Juliet Tomato is a heavy feeder, thus provide them with a good amount of fertilizer throughout their growing season. Keep the cutting in a well-lit area where it will receive direct sun.



The blooms of Juliet Tomato are yellow in color. The variety blooms in June and July. 



Your Juliet Tomato will grow to a height of about 4 to 6 feet (1.2 to 1.8 meters). Since the plant is a vining variety, it’ll require a wide space for spreading.

It is preferred to leave 4 feet (4 meters) of space between each plant.

Several gardeners avoid pinching the buds from the Juliet as it is a high producer that can easily hold large bunches of 18 tomatoes in each cluster. 

As long as you offer it proper water, light, and nutrition, it will keep maturing healthily.

It will take almost 60 to 70 days to fully mature in normal soil and water conditions.

Juliet Tomatoes are indeterminate, they will keep growing throughout their growing season, and you will be rewarded with a lot of delicious cherry tomatoes.

Common Problems for Juliet Tomato


Early Blight

Early blight is a common disease found in Juliet Tomatoes, caused by Alternaria linariae. You’ll notice tiny brown lesions on the mature leaves.

The spots eventually enlarge, forming a ring-like structure at the center of the affected area. The tissues that surround the affected area will start turning yellow in color. 

If during this time, humidity and temperature are increased, the foliage will die.

The preventive measures include using tomato seeds free of pathogens. Also, avoid applying water on the foliage of your Juliet Tomato as this increases the humidity.

In case it needs fungicide treatment do apply mancozeb.


Bacterial Wilt

Bacterial wilt is a very serious disease caused by Ralstonia solanacearum. The disease can survive in the soil of Juliet Tomato for a very long time and eventually enter the plant through damaged roots.

The disease will progress rapidly in hot and moist conditions. The bacteria will multiply rapidly in the tissues of the plant, leading it to wilt while the foliage is still green.

There is no chemical cure for this disease, and the only solution is to throw away the affected Juliet Tomato.


Bacterial Spot

Bacterial spot is caused by species of Xanthomonas. The bacteria will infect your green Juliet Tomatoes rather than the red ones. Bacterial spot is very frequent in wet conditions.

The infected fruit and leaf of the Tomato will have spots on them. This then results in the sunburnt fruits’ poor growth and development. The spots are usually yellow-haloed and dry in the center.

Avoid watering your Juliet Tomato in an overhead manner. Frequently spray the plant with fungicides to have good control over the bacteria. 

Always dispose off the severely affected tomatoes.
