Given that the hot, dry summers of my youth are nowhere to be found in this chilly rain forest, I’ve devised an alternative plan that happens to befit this geography: container garden tomatoes.
Here in the Northwest soil temperature is as big a deterrent to planting as are cloudy skies. Between the two, I’ve experienced tomato transplants that sit soldier-like in frigid soil well into May, only to finally die a shivering death just before the sun appears for the summer. I’ve had trays of seedlings thrust their anxious leaves joyfully through the soil and then be sizzled by an unseasonal day of heat. And I’ve had precious starters drowned by lingering showers before they have a chance to thrive.
The happy fact is, however, that even in this soggy environment you can grow robust tomato vines. Just make sure you have at least a few hours of full exposure for best results. By implementing a couple of tricks, you’ll be able to extrapolate that sunshine into a beautiful feast.
This potting technique works best with starters, either large seedlings you’ve started yourself, or store-bought transplants. Look for the sturdiest stems and close-set leaves. A leggy plant is indicative of a weaker plant.
Begin with a dark container of some capacity, perhaps 1.5 cubic feet or so. You’ll want the tomato roots to have plenty of room to collect moisture and nutrients from the soil, and the dark color warms up faster to attract more of the day’s heat, boosting the growing season. Place the pot in a sunny location. Later in the season when the sunshine is more reliable, you’ll need to be sure the pot is kept well-watered or protected from the worst of the late afternoon sun.
Ensure the pot has a good drainage hole at the bottom. If your pot does not have a drain hole, either drill one yourself using a round hole saw blade, or plan to use a liner of some kind that does. Then line the bottom of the pot with an inch or so of large gravel.
Fill your container or liner with potting soil to about 2” from the top and pack it firmly with your hands. Next, dig out a hole about 2” wider in circumference than your plant, and 3” or so deeper. Remove the plant from its container and set it in the bottom of the hole, ensuring that the lower leaves will be below ground level. Once planted, these leaves will root, providing more stability and nutrient avenues for the vine.
Pack soil firmly around the plant, adding more as needed to keep it firmly upright. Water the plant thoroughly but gently, until the excess begins trickling out the drain hole. For the next couple of weeks while the roots set in their new environment, protect the plant from excessive rainfall or unseasonal heat, and keep the soil moist but not wet.
If you’re so inclined, plant a smaller pot with basil at the same time. Tomatoes and basil prefer the same exposure, making them perfect partners. Just don’t make the mistake of planting them together—both will grow larger than you expect, and could steal nutrients or simply overpower the other.
Salut!
