| In the last 15 years of off and on growing of vegetable gardens in Makawao and Nanakuli, I have discovered some vegetables are easy to grow and productive, and others aren't. Vegetables planted in the ground are susceptible to root-knot nematodes. Before I discovered how damaging these are I watched cucumbers, peppers, string beans, eggplant, strawberries, and tomatoes get up to bear only to die back and whither. These I have found must be grown in pots of sterile soil. sweet potatoes, green onions, taro, okra, dry-land watercress seem to do well in ground. They must be resistant to the nematode. Keep in mind, the pineapple growers fumigate with a very poisonous chemical to rid their fields of nematodes, and that chemical has poisoned the ground water on all the islands. So getting rid of the nematodes in the soil is difficult if not impossible. Squash, beans, and cucumbers all get rust. You make the rust worse by overhead watering. Some people spray with dormant oil and fungicide. I have heard baking soda is a good fungicide with dormant oil, and it is cheap and non-toxic if it works.
I hope other gardeners who read this post will offer their advice. We gardeners need experienced growers to save us from trial and error. |

| Thanks, that's great info! My results are a bit different from yours, could be 'cause I'm on windward side, at 1500 foot elevation; I've had great luck with Hawaiian Chilies outdoors in the ground, same plants going strong for 3 years; jalapenos and other haoli chilies have produced well for a season or two. String beans do great in the ground here, too, and I've got eggplant and strawberries that have lasted 2 or 3 years. Cukes, tomatoes, zukes--there I'm in total agreement with you! We grow them in the greenhouse with fresh soil/mulch each season, but that's not enough anymore, we'll have to switch to containers. I've completely given up on snow peas, spinach, broccoli, but swiss chard, cabbage, kale do great. herbs mostly need to be grown under cover so they don't drown--we get 170" rain a year, you may have different results. Who else has results to share? |

| Well, I don't have a ton of veggie experience to share; I used to live on the Big Island and mainly grew fruit trees there, but have gotten into growing some veggies in my back yard here on Oahu in the last few years (Kailua, but not very close to the ocean, so salt is not an issue). I rent, so most everything I grow is in containers. I use whatever I can find for containers, but mainly those big Rubbermaid Roughneck tubs. They seem like mini garden beds to me, and the plants definitely seem to do better in those than in pots. I start them off with the cheapest potting soil available (usually Super Soil) and then fertilize every so often with an organic fertilizer. I'm still learning what I can and can not grow easily here in Hawaii, and in this area specifically. Ok, so the big successes: Kale does great, and I love it! Chard does very well, but sometimes gets diseased to the point that I have to take it out. Lettuce used to bolt very quickly, until I started growing the UH "Anuenue" lettuce, which is more bolt-resistant. I also have 3 large bushes of UH Waimanalo Eggplants (each in their own Rubbermaid tub) and they produce so many eggplants I'm actually getting a little tired of them. I'm also growing yardlong beans, which are popular in hot, humid Asian countries. These do great; fast growing and heavy producers of delicious, tender green beans. Radishes never fail, but I'm not really a huge fan. They're healthy, so I do grow them occasionally. I've also gotten a lot of nice fruit off of a volunteer cherry tomato bush. Other things that are growing like weeds; basil, mint, fennel, rosemary, cilantro, parsley, and green onions. I am also trying some other things, but the plants are just getting started, so I don't know how they'll actually produce. I'm growing 2 different kinds of Asian cucumbers from Evergreen Seeds (they have so many seeds for different Asian plants that I'm thinking would be better adapted to out climate than seeds bred for North American climates). Also trying some different kinds of Asian melons, also from Evergreen Seeds. I'll have to see how they hold up against fruit flies too, or if I'm going to have to bag them while they grow. I'm trying 2 different kinds of sweet potatoes; the typical Hawaiian purple sweet potato, and also a white-fleshed one that my sister gave me. The vines are thriving like crazy, but it's not time yet to dig and see if there are any tubers. I know the leaves are edible, but I don't care for them too much. But, if I ever get hungry enough, I'm glad they're out there as an option. I'm also growing long squash and kabocha squash. I did get one long squash from my older vine (totally delicious and ridiculously huge) but for the most part the flowers don't get pollinated and I'm too lazy to climb up the tree where it's growing and do it by hand. I planted 2 more long squash vines though, so hopefully with more vines there'll be a lot more pollinating going on. Also trying UH seed program cherry tomatoes and UH bell peppers, and a few Asian eggplant varieties from Evergreen Seeds. All are doing well so far, but are not old enough to produce. Things that didn't work well for me AT ALL: beets (never got very big, but the tinies were tasty; I'm going to keep trying with these, because I do love beets), standard bush pole beans, dill (i think it just got too hot for it; i'll try again in the winter), and spinach was a total joke. Though I do know of a farm on the Big Island that actually grows spinach organically in volume, so it can definitely be done. Sorry, I wrote a whole book here, I think! This is why I don't post on forums; get me started about my garden, and I have no idea how to be concise :) |

| Here at about 1000' on the windward side of West Maui i have grown arugula, bok choy, cabbage, broccoli, cauliflower, chard, bush beans, lima beans, pole beans, tomatillos, garbanzo beans, snap peas, snow peas, leeks, round onions, carrots, onions, shallots, ginger, all kinds of herbs, wing bean, pipinola, cherry tomatoes, asparagus, turnips, radish, beets, peppers, eggplant, lettuces, kale, cow peas, long beans and zucchini. All pretty much grown right in the clay although i do have a few raised beds. I took a soil sample to the extension office and amended based on the findings before i started planting and that seems to have really helped. I also try to rotate plantings and amend with as much organic matter as i can get my hands on. The things i've had trouble with include regular sized tomatoes, melons, squash and cucumbers due to fruit fly damage. I've abandoned spinach because chard grows so much better and the perpetual variety is a decent substitute. Fava beans and runner beans grew but not very well but i want to try some different varieties before i give up on them. Tried peanuts one year but the birds ate them. Peppers are hit and miss between the fruit flies and the pepper weevils but i enjoy some success as well. Planting things at the right time of year really helps. I don't worry too much about plant disease and i don't like to spray insecticides but the bugs can really get you down. Floating row cover is a gardener's best friend. So lilaalil i guess you are not the only one who has hard time being concise ; ) |

| Update: just got my first sweet potatoes! I planted some a bunch of slips about 4 months ago in one of my old rubbermaid tubs with some potting soil. Just dug them out and got about 15 nice potatoes. They were grown from one of those purple-skinned, white-fleshed sweeet potatoes from the grocery store. The best part is, I just replanted the vines again, and in another 4 months should get some more potatoes, all off of one parent potato from the grocery store. I also have a bunch more growing in this raised bed filled with red clay soil that came with my house. They've been there about 2 1/2 months, so in a month or so it'll be time to dig those out and see how they did in the clay. Supposedly clay is not the best for these, but I had the slips needing a home, and that bed just sitting there empty... we'll see. |

| Congratulations on your harvest! Sweet potatoes are good any time of year but especially now. Sweet potato haupia pie maybe? Containers are a good idea for sweet potatoes. Easier to harvest and easy to contain. The vines will take over the world if you look the other way for a little too long! It will be a good experiment to see how the sweets do in clay v. container soil. I usually end up slicing all of mine in half with the shovel ; ( Still good to eat! |
