To grow your tomatoes successfully in Hawaii, you need to consider a lot of factors. Knowing this information will give your plants a good head-start and result in a healthier and tastier harvest.

1.      Choosing the Right Location

The location where you live plays a significant role in determining the success of your tomatoes.

  • Your tomatoes will grow much better if you live in a sunny, dry coastal area.
  • If you live around the middle mauka range with an elevation of about 800 feet, then such areas have more moisture and humidity in the atmosphere. It may cause fungal infections and frequent rain and make the tomato plants more susceptible to mildew.
  • The climate starts getting colder when we move towards higher altitudes.
  • The air’s humidity also increases, making it even more challenging to grow tomatoes.

You cannot change your location to grow tomatoes, but you can create a greenhouse or plant tomatoes indoors, providing them with favorable conditions.

2.     Grow From Seedlings to Have a Good Start

You can grow your tomatoes either way.

  • Seeds and seedlings both have their merits and are proven to be effective.
  • Using seeds is much easier and inexpensive and results in more plants.
  • However, using seedlings will give your plants a good head-start for the growing season.
  • When using seeds, you cannot tell how many of them are viable and will sprout, so you must plant extra and provide intensive care.
  • Seedlings are already sprouted, developing, and growing and can be replanted in your garden, ready to grow!

Once you have decided if you want to grow from seeds or seedlings, choose the right variety.

3.     Choosing the Right Variety of Tomatoes

Another crucial tip to remember is to choose a good variety of tomatoes that will thrive in the climate of Hawaii.

  • Some varieties do better in tropical climates and give a better harvest than others.
  • When growing tomatoes in Hawaii, choose the varieties with smaller fruits and thicker skins. These protective skins will make fruits resistant to pests that thrive in tropical lands and devour fresh fruits.
  • The best varieties to grow in Hawaii are cherry tomatoes, golden yellow, San Marino, and Roma tomatoes.

Some other varieties of seeds known to grow well in the climate of Hawaii are Healani, Kewalo, and Anahu varieties.

4.     Learn More About the Environment

Knowing the environment is crucial to having good growth and a healthy harvest.

  • The climate of Hawaii has its fair share of insects, pests, fungus, and mildew, making it a challenge to grow tomatoes.
  • If you are determined to grow your tomatoes, you can grow them in greenhouses, under eaves, or in any container.

It will make it easier to control the environment and keep the plants and fruit safe from infestations.

5.      Soil Type of Hawaii

Learning the type of soil is very important to have healthy growing plants.

The quality of soil in Hawaii is quite poor. The soil type is dry, rocky, and has low nutrition, making it necessary to amend as per the needs of the plants.

  • Tomato plants prefer mildly acidic to neutral soil with an optimal pH value ranging between 6.0 to 6.8.
  • Adding organic matter to the soil is also recommended to enhance the nutritional value and acidity of the soil.
  • Taking good care of the soil and providing healthy nutrients will result in a bountiful and abundant harvest.
  • If the soil quality in your area is bad, try using pots and containers or make a raised garden bed.
  • Fertilizing the soil using a 16-16-16 fertilizer will enhance the number of blooms, thus, increasing the number of fruits on your plants.

After planting tomato seeds or seedlings, it’s vital to take proper care of them.

6.     Watering Needs of Tomatoes

Tomato plants love water!

  • To keep your tomato plants healthy, water them regularly.
  • Tomatoes love a good amount of water, and they can burn pretty quickly if you don’t provide them with enough water.
  • Water your tomato plants daily or use a drip irrigation system.

You can always feel the soil with your hands or check it with a moisture meter to see when it gets dry. This will help you to be safe from overwatering.

  • It will help establish root networks and boost the plant during the growing season.
