Lycopersicon lycopersicum The first ripe, juicy tomato of summer is a delicious milestone of the season for gardeners. Each year we test and evaluate more than 250 tomato varieties to bring you the most flavorful, best performing selections, for every desired use.

Days to maturity are calculated from date of transplant.

Determinate tomatoes: grow compactly, sprawling laterally, usually do not require staking, and fruit ripens over a short period of time
Indeterminate tomatoes: grow on long vines, generally require pruning to 1 or 2 leaders that need to be trellised
• Fertile, well drained, raised beds covered with plastic mulch promote early growth and better yields
• Tomatoes are high feeders and will benefit from regular fertilization with Age Old Bloom
• To prevent blossom end rot use a high calcuim amendment
• Overwatering can cause fruit to crack

Direct Sowing
• Not recommended

• Sow seeds in trays 6-8 weeks before anticipated transplant date; up-pot into 3-4 inch pots when the first set of true leaves appears
• Strong light and cooler temperatures (60-70°F) prevent plants from getting leggy
• Fertilize with Age Old Grow every 10-14 days
• When transplanting work in compost, 1/2 cup of TSC's Complete fertilizer, and handful of bone meal
• Determinates can be spaced 18-24 inches apart, indeterminates 24-36 inches apart
• Tomatoes can be buried up to the top 2 sets of leaves
• Use Kozy-Coats or Victorian Bell Cloches to protect young plants

Insects & Diseases
Common insects: Flea beetles and tomato hornworms
Insect control: Pyrethrin or row cover for flea beetles, and Monterey B.t. for tomato hornworms
Common diseases: Early and late blight
Disease prevention: A strict 3-4 year rotation, remove vines at the end of the year, fungicide

Harvest & Storage

Best Slicing Tomato

We have grown Siltz tomatoes for many years and have had great luck with them. They are extremely dense and a perfect sweet tomato for slicing. I also make a lot of tomato sauce each year (canning and freezer) and these tomatoes are great for this as well. I definitely add some extra bone meal and ground egg shells when I plant them and they do well. We will continue to buy organic seeds of this variety year after year. We love them!
4-STARS! Big Early Delicious Red

I've been growing this variety for nearly 20 years -- since about 1995 (I believe it first came out in 1994). It is the best EARLY, big, red, delicious & consistent tom that I know of. I've grown several hundred varieties over the last 40 years, all organically, in a wide variety of soils and micro-climates in CA, MA, AZ, IL ... and Siletz has always been a great early performer.
It ripens even in

It comes through even in "green tomato" summers. Three out of the last five years, Siletz was the only tomato to ripen in my garden. My area frequently gets marine layer overcast and even other "Early" tomatoes sometimes fail to ripen on the vine. Not this medium-sized beauty. And it tastes great. What's not to like?

I planted this one for the first time this past season. Started in the greenhouse, planted out in mid-May. This is a sturdy, low-growing plant, no need to stake. The great, big lobed fruit just kept on coming in waves. I was canning for several weeks at the end of the season, nice not to have them all ripen at once! Be sure to look low on the plants under the leaves - they hide down there! Very happy with this tomato - will definitely plant again this coming year!
