3 Steps for Propagating Black Krim Tomato Plant
Propagating Black Krim tomato plants can be done through seeds or cuttings. Here’s a step-by-step guide for each method:
Propagating from Seeds
Seed Collection
- Choose the Fruit: Select a healthy, ripe Black Krim tomato from your garden.
- Extract the Seeds: Cut the tomato open and scoop out the seeds along with the surrounding gel.
- Ferment the Seeds: Place the seeds and gel in a jar of water and let them ferment for 2-3 days. Stir daily. This process helps remove the gel coating and kills off any seed-borne diseases.
- Clean the Seeds: After fermentation, rinse the seeds thoroughly in a fine mesh strainer to remove any remaining pulp.
- Dry the Seeds: Spread the seeds out on a paper towel or a plate to dry. Allow them to dry completely for about a week.
Starting Seeds Indoors
- Timing: Start seeds indoors 6-8 weeks before the last expected frost date.
- Containers: Use seed trays or small pots with drainage holes.
- Seed-Starting Mix: Fill the containers with a sterile seed-starting mix.
- Planting: Sow the seeds about 1/4 inch deep in the soil. Cover lightly with soil.
- Watering: Moisten the soil gently with a spray bottle.
- Light: Place the containers in a warm, bright location or under grow lights.
- Temperature: Maintain a temperature of 70-75°F (21-24°C) for optimal germination.
- Germination: Seeds should germinate in 7-14 days.
Transplanting Seedlings
- Hardening Off: Gradually acclimate seedlings to outdoor conditions by placing them outside for a few hours each day over a week, increasing the time each day.
- Planting Out: Transplant seedlings into the garden or larger containers after the last frost date. Space plants 24-36 inches apart.
Propagating from Cuttings
Selecting the Cutting
- Choose a Healthy Plant: Select a healthy, disease-free Black Krim tomato plant.
- Take a Cutting: Use clean, sharp scissors to cut a 4-6 inch long sucker (a side shoot that grows between the main stem and a leaf branch) from the plant.
Preparing the Cutting
- Remove Lower Leaves: Remove the lower leaves from the cutting, leaving only the top 2-3 leaves.
- Optional Rooting Hormone: Dip the cut end of the cutting in rooting hormone to encourage root development (optional).
Rooting the Cutting
- Water Method: Place the cutting in a glass of water, ensuring the cut end is submerged but the leaves are above water. Change the water every few days.
- Soil Method: Alternatively, plant the cutting directly into a pot filled with moist, well-draining potting mix. Water gently to settle the soil.
Caring for the Cutting
- Location: Place the cutting in a bright, indirect light.
- Humidity: Cover the cutting with a plastic bag to create a humid environment, but ensure the bag doesn’t touch the leaves.
- Root Development: Roots should start forming in 1-2 weeks. Once roots are established (if using the water method, you’ll see roots; if using soil, give a gentle tug to feel resistance), transplant the cutting into a larger pot or garden bed.
Transplanting the Rooted Cutting
- Hardening Off: If the cutting was rooted indoors, harden it off by gradually exposing it to outdoor conditions over a week.
- Planting Out: Transplant the rooted cutting into the garden or a larger container. Space plants 24-36 inches apart.
By following these steps, you can successfully propagate Black Krim tomato plants from seeds or cuttings, ensuring a continuous supply of this delicious heirloom variety.
