Most people categorize this variety of tomato as abeefsteak , due to its rounded fruits that can weigh six to eight ounces and try good slice for sandwiches and salads .

Known to have traveled extensively in Italy in 1787 , Thomas Jefferson grew the tomato in his gardens at Monticello , starting in 1809 .
It ’s not a particularly common variety outside of Italy , but it does have bunch of fans among bon vivant , chefs , and preservationist .
For example , the folks who planted the 1812 Garden at Historic Fort Osage in 2009 in Sibley , Missouri , let in a variety they name to as “ Thomas Jefferson ’s 1809 ‘ Costoluto Genovese ’ ” in their plot , demonstrate the day-by-day practices and life-style of a gone era with a nod to the historic garden of the third US President .

Propagation
Because they ’re not widely available as alive starts , it ’s of import to plan ahead if you intend to maturate ‘ Costoluto Genovese ’ in your nursing home garden .
You ’ll most likely need to sow the ejaculate yourself .
To give the plants the command 75 day to strain due date from transplant , sow in the seeds indoorsabout six calendar week before the metre you anticipate being able to transplant them into the garden .
Shoot for jump them four weeks onward of the intermediate last Robert Frost date in your area . That should give them enough sentence to sprout , grow several circle of true leaf , and harden off ahead of planting out of doors .
Do n’t utilize ordinary garden soil for this task . or else , inseminate the seed in a specially forge cum - starting mixture .
seed them a fourth of an in cryptic , industrial plant one seed per one - inch cell , or imbed multiple seeds two inch asunder in a shallow tray with drainage holes .
Be sure to nestle the cells or tray in a second tray without drain so the dirt will stay dampish without run out excess water on your workspace .
Cover the tray with a clean humidity covered stadium or charge card wrapping , and use a spray bottle of water to keep the soil moist but not blind drunk until the seeds germinate .
Keep the temperature at 70 to 75 ° fluorine until you see sprout , which unremarkably take about seven to 14 Clarence Day . You may require a heat mat if your business firm is not that affectionate – I know mine is n’t !
After the seeds germinate , move them as quickly as potential to an area expose to a impregnable informant of light , be that agrow lightor a cheery windowsill .
Then keep them moist and in the temperature range of 60 to 70 ° F until it ’s prison term for them to graduate to large cells , or to be hardened off and transplant outdoors .

While this method does n’t come up often , it is also possible to commence ‘ Costoluto Genovese ’ plants from cut , particularly if you live in a ardent part where tomatoes may be grow as perennial .
If you ’re able to locate full - size industrial plant to put up cutting for root , and if you have clip tosuccessively plantadditional starts of this motley in the course of the growing season , keep this pick in judgment .
fundamentally , you would need a six - inch tip burn from a healthy love apple flora for each new start – a theme that has n’t started setting fruit .
Snip off any flowers before you test to rout the carving , and strip the leaves from the bottom of the stalk until you only have two folio left at the top .
Fill a four - in container that has drainage pickle with about three column inch of dampened all - intention potting stain .
I prefer to use biodegradable pots so I can transplant the start pot and all , but repurposed milk cartons or other pots you have around are ok too , as long as they ’re fair and have been sterilize with raging soapy water or a diluted bleaching agent solution .
practice a table knife to make a muddle to put in the base into , stopping just half an in from the bottom of the container .
deem it upright , range the stem into the yap . Tamp the soil , then firm more territory around the stem until all the nodes that you removed leave from are covered .
Place the container on a saucer or plate to bewitch any water that leaks out , and place it in a protected spot with a temperature around 70 to 75 ° F .
A windowsill with collateral Christ Within is best , or a fleck near a wall on the patio may work if the conditions ’s systematically strong enough .
Keep the soil moist but not saturated , using a white spray feeding bottle of water .
The potted cutting off need to stay out of the verbatim Lord’s Day at first , but after a week you ’ll require to move them into spots with progressively potent light until by week two they are turn in full sun .
At that point , check for root . you may transfer the rooted cutting travel along the same summons you would with ‘ Costoluto Genovese ’ grown from source indoors .
