Container Tomato Trial 2008

Nine Palms Ranch Trial, 2008

Lead: Gil Patrick

Team members: Betsy Fisher

Summary

Many of the container tomatoes did as well or better than the in-ground tomatoes, including the indeteterminate (full-size) varieties. Container gardening with full-size tomatoes is something we can recommend.

Overview

Eight tomato varieties (Azoychka, Carbon, Flashen, Henderson’s Winsall, Howard German, Siletz, Spears Tennessee Green, and Sprite) were grown in black 15 gallon plastic pots. Three of these varieties (Flaschen, Siletz, and Sprite) were also grown in black 5 gallon plastic pots. The trial was to compare the flavor and production from container tomato plants to in-ground tomato plants

Soil preparation

The potting soil mixture was Sunland planter mix and 1/3 horse manure.

Seeding and transplanting

The seeds were started in March and transplanted into the pots in May.

Watering

The pots were hand watered twice a week.

Fertilization and pesticides

They were fertilized once with Whitney Farms organic fertilizer. No pesticides were used.

Comments
Azoychka, 15 gallon 56 25.5 lbs 28 lbs Beautiful looking yellow tomatoes but not much flavor.
Carbon, 15 gallon 55 17.5 lbs 21 lbs I grew Carbon tomatoes at my home and the taste was excellent but the Carbon tomato plants at Nine Palms were not the same. Not sure why the plants were inconsistent.
Carbon, 15 gallon 48 18 lbs Second Carbon tomato
Flaschen, 15 gallon 71 1.5 lbs 1.5 lbs The 5 gallon pot had more tomatoes than the 15 gallon pot. Flaschen is not a tomato I would grow again. Not much flavor – a waste of water as far as I am concerned.
Flaschen, 5 gallon 90 2.5 lbs
Henderson's Winsall, 15 gallon 19 9.5 lbs 16 lbs Nothing special. Some people liked them, but I didn’t care for them.
Howard German, 15 gallon 98 22 lbs 17 lbs Good tomato for sauce.
Siletz, 15 gallon 74 22 lbs 16 lbs Tomatoes had good flavor. Large crop from small determinant plant.
Siletz, 5 gallon 10 2.5 lbs Died early.
Spears Tennessee Green, 15 gallon 58 31 lbs 28 lbs I like the tomatoes but they are a bit tart and didn’t do well on the taste test at Nine Palms.
Sprite, 15 gallon 244 2 lbs 11 lbs Poor production, poor flavor and waste of time to pick.
Sprite, 5 gallon 67 7 oz

Note

Do not put the pots on a concrete slab in full sun or along the south side of a house or building as this is too much sun/heat.

Conclusion

Many of the container tomatoes did as well or better than the in-ground tomatoes. Container gardening with full-size tomatoes is something we could recommend at the Spring Garden Market for people who have limited space. We could offer 15 gallon pots with cages and recommend tomato varieties at the sale.
