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
• Harvest when fully ripe, do not refrigerate for best flavor
• Green fruit should be ripened in a cool, dark area; make sure fruit are not touching

We most appreciate how the plant stays compact as we need to contain these plants in a (20"w.X20" h. round) cage due to heavy wildlife intrusion. The clusters of tomatoes ripen earlier than other varieties we have tried and have a nice enough flavor for fresh eating.
Bigger than Stupice!

I started this as a seed in January at the same time as some Stupice tomatoes. I wanted to see if this would REALLY REALLY withstand cold wet springs, so I hardened them off over two weeks and put them out April 1st. The Oregon Springs are big and burly... the Stupice are tiny and sickly. Now I know which cold hardy variety I will use from now on!
