Package incorrect

I was flipping through a seed catalog for fun and noticed that these were indeterminate. I have grown these in the past. But I grow a lot of Toms. I unfortunately put them with no trellis. I’ll have to figure something out. Very nice plant.

Its look like some people have struggle with these. The SW Idaho dry heat can make fruit set tough on many tomato varieties. I have a south facing yard, and I grew them in a pot next to my west fence so they only got morning sun with no shade cloth, and this was one of my best producers. I started several plants and gave 4 or 5 away to people in the subdivision and coworkers and they all had success and loved the flavor. Everyone asked if I had more, unfortunately this year I sunburned several of my plant starts during the hardening process so lost several. My suggestion is position them in the middle of more heat/sun tolerate varieties, shade cloth, or position the plant for morning sun only. Also hit them with good amounts of bonemeal/phosphorous come July, late June, might be able to start blooming and encouraging fruit set a couple weeks early before the most intense heat hits in August.

Plant growth habit is labled wrong.

My wife wanted me to purchase this tomato several years ago so I did. I prefer to grow determinate tomatoes as they're easy to cage and manage. Much to my surprise, Cosmonaut Volkov is NOT A DETERMINATE TOMATO, just the opposite, it is an INDETERMINATE TOMATO. The description and classification NEEDS to be changed. Search any other online seed catalogue for this tomato and they ALL say it is an indeterminate tomato.

It does have good flavor but in my opinion, tends to go mushy soon after ripening.

Incredible producer!

I planted just two of these last summer- they both went crazy, producing buckets of fist-sized tomatoes that were delicious. Favorite tomato of 2021!

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 calcium 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
