Over the years I have made occasional attempts at growing tomatoes but with no great success. New gardeners in town, who were tomato kings back in California or Utah, have given up in frustration and passed their tomato cages to me so I do not feel so bad. However, after retirement, it seemed that it was time to get more serious about growing tomatoes and see if I could be a bit more self-sustaining. After all, I do eat a lot of tomatoes. So, in April of last year (2016), I once again squished the biggest and best of the tomatoes I had bought that week and, after a day or two of drying it out, planted the seeds in a small pot. The local tomato farmers grow only cherry and grape tomatoes, so I decided to go with grape tomatoes this time. Fruit flies are such a problem in Hawaii that growing large tomatoes is just a waste of time unless you are going to bag every fruit.to protect it. I have found the golf ball size cherry tomatoes to be a bit difficult in the past too.
After getting a few small grape tomato plants growing I transferred a few into large containers in the kitchen garden area where they would get full sun. Only one of these actually was alive a month later and eventually starting flowering and then producing tomatoes. Not huge amounts. Maybe a dozen or two a week. But here is why I am writing about it. Over a year later the same tomato plant is still chugging along and still giving me fruit.
It is a skinny vine plant that has small leaves. Its old leaves turn yellow and die off. At first, I thought it was diseased but after a while I realized it was just its habit of growth. On doing a google search I find out that tomato plants are of two types. Determinant and Indeterminant. The description of the Indeterminant fits my plant to a T. A long-lasting vine which CTAHR says is the best for Hawaii growing conditions. The Determinant plants tend to have lots of lush and fast growth of leaves and fruit but do not last long. I have seen that happen with some plants that I bought.
So now I have figured out a tomato that I can grow I am going to up my game and try and grow more plants and also some of those gourmet different color types. I am sticking with grape tomatoes though. I do like these little tomatoes and they freeze very well too. I cut them in half first. Easy to throw fresh tomatoes in a salad. The frozen ones get thrown into a frying pan for stir fries or into a stew. Tomatoes along with an egg, Portuguese sausage and slices of cooked breadfruit all fried up in a pan is my favorite breakfast for dinner meal!
Tomatoes of course are known for their Vitamin C and Lycopene. Tomatoes plants like rich soil and lots of sun. I see them grown in cages or tied up on string. Mine is grown on dead branch props.. They like fertilizer, especially Phosphorus, at planting and flowering time. Because my plant is in a container and long living, I fertilize my plant every month. They need to be watered deeply but allowed to dry out between waterings. Not getting the leaves wet while watering helps prevent disease. It is good to pick the lowest leaves off for the same reason so that they are not picking up pathogens from the soil. I have to pick the tomatoes after they start turning yellow or the birds and wild chickens will beat me to them. It means getting the enjoyment of looking at a row of ripening tomatoes on the kitchen window sill.

Have a look at the netting cage a friend built for her tomatoes so that she could keep the birds from eating them and she could have vine ripened fruit.

Recently noted in a nutrition book that the smaller the tomato fruit the more surface to mass it has. Because most of the good stuff for you is in the skin of the fruit, the more nutrients you are going to get eating small tomatoes rather than a large tomato. I knew that I liked these grape tomatoes!
Another new thing that I am doing in growing tomatoes. This idea came from a guy on a Facebook gardening group that I follow. Instead of spending a lot of time preparing seed from tomatoes you just slice the tomato in thin slices and lay the slices on the soil. A few days later you will have tomato plants. When they get a bit of growth on them you decide which are the strong ones that you want and cut the others down with scissors. Easy peasy.

Last summer I tried a type of cherry tomato. I grew it from a bought, local grown tomato and started it as in the above photo. I figured if they local farmer likes this type, it should grow well in my garden. I was very pleased with the result and have another one in flower now for this new summer coming.

Recently there was a big article in the local newspaper giving advice to home gardeners from Hawaii tomato growers. Very nice of the farmers to be sharing their years of knowledge and experience. I thought of just putting up a link to the article, but it is behind a pay wall so instead I will give a few points from it as it was very helpful advice. Thank you, Neil and Shin Ho. hofarmshawaii.com
* "You have to learn from it. Every time you do a planting, you have to pick up something from past experience."
*They only grow cherry and grape sized tomatoes.
* "We are challenged every day." Spotted wilt, leaf curl, aphids, leaf hoppers, beetles, whitefly, and big rains. "It's just a natural cycle. The plant is not meant to last forever." They plant extra knowing there will be some crop damage.
*Hybrid varieties are best for new gardeners rather than "finicky heirlooms".
*Mostly they grow indeterminate varieties which have multiple cycles. Their growing cycle is 100-120 days while the determinate types last 55-60 days.
*Tomatoes need at least 6 hours of sun a day to avoid diseases.
* Do not over water....it can lead to root disease.
* Fertilize with a NPK of 10-20-20 plus add chicken manure in soil preparation. When flowering, extra potassium nitrate prevents flowers from falling off. They also apply 20-20-20 soluble fertilizer before fruiting.
*Vary the kinds of insecticides used to prevent resistance. Make sure to spray under the leaves and in the morning when sun is not too hot. Homemade remedies like soap and water for insects and baking soda and water for fungus can work. 2 oz per gallon of water.
*Stake and tie the plants up for air movement. They do not bother with pruning leaves or covering with netting. Too labor intensive.
*In wetter, cooler areas of the island you can grow tomatoes in the summer but in hot, dry areas, spring/early summer is better.
* johnnyseeds.com has a large selection of tomatoes. U of H tested and selected seeds for Hawaii can be seen at www.ctahr.hawaii.edu/seed

Grew small, orange cherry tomatoes this summer. Just for fun really. They are pretty in my salad but do not provide much tomato bulk. Very sweet.
