Soil culture

Hawaiian soil is actually poor, rocky and not as nutritious as you would think in Hawaii and needs to be amended. Tomatoes require moderately acidic to neutral soil in which pH 6.0 to 6.8 is optimum also using good organic matter is needed. If you take the time to condition your soil and feed it the right nutrients for tomatoes to grow, you’ll be rewarded with abundant fruits. The best way I’ve produced tomatoes is to enrich the soil with amendments or nutrients, place a lot of mulch as top dressing and to water on a regular basis depending on your rainy weather conditions. If space or soil is more of a challenge, then trying a container version to growing your tomatoes might be an easier way to go in a controlled situation. Fertilizing your plants with a general fertilizer with a  16-16-16 ratio 0r 10-20-20 corresponding to ratios of nitrogen, phosphate and potash mixed in well to the soil and added in a second phase to flowering plants to promote fruit production.

Seeds can be grown in trays and then transplanted in three to 5 weeks’ time frame and supported with cages or even fencing material that I use from leftover material. Place your tomatoes at least 15 inches apart for them to grow well up your trellis and you can easily prune any side shoots for maximum growth patterns.

Watering Requirements

Tomatoes are heavy water drinkers and require regular water or they will sulk and even burn quickly depending on the location. If you take care of your garden daily then you can easily water the plants or even set up a drip irrigation program to take care of your tomatoes water needs. Keeping the soil top dressed and moist keeps your tomatoes very happy and healthy.

Typically, the best growing conditions for tomatoes is under full sun and heat. Even filtered light is good if you cannot get good sunny conditions for growing some plants.

Insects thrive in Hawaii and whitefly, leaf miners, slugs, mice and other tomato loving insects create a real challenge, so keeping them covered, in containers or off the ground in elevated beds helps to keep insects at bay. Daily inspection, using water sprays and insecticidal soaps along with checking out what can be found on the plant for further treatment is a good and preventative measure for additional treatments.
