Know before you buy
Parthenocarpy means the plant can set fruit without the need for pollination. This makes the Siletz an exceptionally reliable producer, even in cool or wet weather conditions where pollinators might be less active.
Yes, even though determinate plants have a compact, bush-like growth habit, they still benefit from staking or a small cage. This keeps the heavy fruit off the ground and improves airflow to prevent disease.
The Siletz is known for a generous yield of 7–10 ounce slicing tomatoes. Because it is a determinate variety, you can expect a concentrated harvest over a shorter period, which is ideal if you plan on canning or preserving.
Yes, because this is an open-pollinated variety, you can successfully save the seeds from your harvest to plant in future seasons. Keep in mind that the fruit is nearly seedless, so you may need to harvest from several plants to collect a significant amount of seed.
Under optimal conditions, you should see emergence within 6 to 14 days. Ensure you plant them about 1/4 inch deep in warm, moist soil to encourage the best start.
Absolutely. Their compact, determinate growth habit makes them an excellent choice for large containers or raised beds where space is limited.
