I have been doing some succession planting of lettuce. I cannot eat that much lettuce at one time so it is better for me to start 8-10 lettuce seeds in a pot and transplant the individual seedlings to the garden when they are about thumb size. I can plant them in a bed by themselves but, since the snails love them, I prefer to tuck them between other plants. I will restart seeds every 3 weeks or so. My best planting season will be November- May. Lettuce bolts and struggles through summer so I would rather grow kale and Chard instead as a year round green.
Usually in my main garden I do this. My main garden is acidic pH 6.0 in a raised bed 8ft wide and 16 ft long oval shape.
Plant warm season crops. First planting of Corn (tropical or temperate) Either UH #9, #`10 or Silver Queen.
If I choose to plant corn. Only lettuce, beets, daikon, and carrots can grow between them. Corn will take up all the space in the main garden.
I can still plant cool season crops in March.
Succession lettuce. I start seeds in pots about 8-10 seeds and plant out every 3 weeks or so until May. Lettuce is ready in 30-55 days.
Komatsuna, Chard, Kale, Broccoli are planted in September and leaves can be harvested until May or I remove them for the corn.
If I forego corn in Mar. I can plant okra, 4 cucumbers on a trellis, bush beans, beets, NZ hot weather spinach (also good in a container), amaranth, and or sunflowers.
I do keep cutting celery, Jamaican oregano permanently in the garden. I also have aloe permanents on one side of the garden.
In my 4 18 gallon pots that have a 7 ft trellis I can grow a combination of these plants
9 pole type beans or 9 snow peas in an 18 gallon pot.
4 parthenocarpic cucumbers usually Diva or Suyo long in an 18 gallon pot or on a trellis in the main garden.
3 tomatoes ( I can trellis up to three tomatoes, but since I am having issues with TYLCV, I only plant Charger and it does not require a 7 ft trellis so I can use a large tomato cage instead.
In 18 gallon pots anywhere else in my yard where I have room. I typically have:
Citrus trees in pots ( have about 14 citrus trees at my last count. I may have lost a few)
Bay leaf (2-5 gallon pots)
Peppers hot ( 1 gal up to 18 gallon pots for the larger and longer lived peppers)
eggplant 18 gallon max 2 plants are more than enough.
Green onion, garden and garlic chives in 1 gallon pots ( I usually have a few of them 3-5 pots)
Mint (in 14 inch bowls. They need to be contained. I have chocolate, peppermint, and spearmint)
Ginger, Jamaican, turmeric, galangal. Pots have to be wider than deep. Number of pots depend on the no. of roots I choose to keep.
Taro, araimo. 3 pots need to be both wide and deep. 3 gallon minimum
Pitaya. (well that one makes its own space. I just have to keep cutting it back and pulling it from the fence or it will try to escape to th neighbor's yard
Bittermelon ( its a weed in my yard. The birds bring the seeds)
Lavender. Would prefer to be in the ground, but I need to keep them in pots so I can move them out of the rain in the rainy season.
June- July- August. June possible to plant another crop of sweet corn. Otherwise, plants are taken out as they mature and the garden is left fallow for the summer. It is too hot to plant and costs too much to water it.
September- plant seeds of cool season crops broccoli (DeCicco, Italian Sprouting) so plants will mature in November. Side shoots can be harvested till May. Gobo needs to be planted in a tall tube to accommodate the 3 ft roots. Plant all root crops (beets, daikon, carrots, kohlrabi)
taro ( harvest and repot), turmeric (harvest and repot) Ginger will be harvested after it blooms (Sept-Nov)
Cool season crops can be planted Sept-May
Onions seeds start in September, Garlic chilled in July and planted October 25.
A third crop of tropical corn can still be planted in September.
Tomatoes are good for about 8 months if they are not overcome with disease
Chard and Kale are good for up to two years
Komatsuna one year.
Cutting celery , parsley, 2 years
Papaya 3 years or until the fruit cannot be reached
Eggplant 2-3 years. They do live longer, but production drops
Herbs : thyme, green onions, chives, ajaka basil, lemon grass, ginger, chilies are mostly grown in pots. Herbs tolerate pots well and they would take up a lot of space for a long time if left in the main garden.
I prefer to plant short crops 100 days or less and crops that do not take up a lot of space in the main garden.
I have grown carrots, but carrots and onions are not easy for me to grow, they take up a lot of space for a small yield. I am better off buying these and planting something else instead.
Squash and gourds need space on a fence or on the ground to ramble. I only grow these in my other garden plots that have more space for them and because they can usually take care of themselves for a long time.
Happy gardening in Hawaii. Gardens are where people grow.
