Longkeeper plants are the best

The tomatoes from the Longkeeper plant last a L O N G. time. I would definitely buy the PLANT again - NOT the SEED. I have rotten success (none) with starting seeds and growing plants from seed. Please offer the plant again😊

True to its Name

A friend gave me these seeds and I decided to try them. I harvested these green, orange and colors in between, on Oct. 2 before a hard frost. While they don't have the flavor/smell of regular tomatoes, we were thrilled to be eating our own tomatoes at Christmas and beyond. Unbelievably we still had a few in Feb. and saved one to eat on Mar. 1st just to say that we did. It was a bit soft, and not very flavorful, but again, it was ours and not store-bought. I stored them in the basement in a single layer in a shallow box. I will grow these again just to have tomatoes into winter.

Disappointed, will not grow again.

I was intrigued by the description of this tomato. It grew nicely and had a lot of green to slightly yellow tomatoes by the time I had to harvest before cold weather arrived. Almost three months later two or three tomatoes were approaching an orange/red color so I tried them. They had less flavor than store bought tomatoes. The rest are still yellow, or starting to spoil. I'm going to discard them all.

This was a terrific tomato year here in the Puget Sound area. All other varieties did great. I was able to ripen the remaining green Stupice and San Marzanos using the technique described for this variety. They were great.

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
