Growing La Roma III Red Hybrid Tomatoes
In cooler climates, La Roma III Red Hybrid seeds are best started indoors in early spring. Begin sowing summer annual tomato plants in either March or early April, with a seed-starting container under grow lights or in a greenhouse. Plant seeds 1/4" in a warm moist seed-starting mix. Use a root growth fertilizer at the time of sowing. Germination will take 1-2 weeks. You can sow La Roma III Red Hybrid Tomato seeds outdoors once the threat of frost has passed or once your region's night temperatures don't dip below 45°; this sets La Roma III Red Hybrid apart from other late season tomatoes, as those varieties should stay indoors until climate conditions stay above 50°. These Roma tomato hybrids prefer full sun and a temperature range of 65-95° with at least 50° for germination. After 6 weeks or once seedlings grow 3-4" tall with 1-2 sets of true leaves, harden off plants before transplanting outdoors. Till rich, composted soil and prepare 8-12" holes. Remove all of the smaller leaves on each La Roma Hybrid plant, leaving a single top set of sturdy leaves. Plant just 2" above the soil, with only their top set of healthy leaves exposed. Space the plants 2" apart with 3-4" in between rows. Use a trellis or stake for support. You can also transfer La Roma III Red Tomatoes to a container at least 14-20" wide and 2" deep to set on your patio, as this small and shorter bush type grows 2-4" tall and doesn't take up too much space. Instead of potting soil, use a rich soilless starting mixture. Feed your resilient La Roma hybrid tomatoes by scattering a fertilizer made of peat moss and vermiculite throughout crop development. Water La Roma III Red Hybrids 1-2" per week. Early season diverse varieties like La Roma Tomato seeds are disease resistant to verticillium and fusarium wilt. In general, tomatoes prefer full sun and rich, warm, well-drained soil with added compost and a pH level of 6.0-6.8. These determinate and consistent seeds yield an abundant crop of bright red 5-8 oz sweet fruit with fibrous texture for a rich summer harvest.
Harvesting:
Depending on which seed variety you've chosen, the period of maturity will differ. Generally, tomatoes are categorized into three seasons as: early, mid and late-season crops. As La Roma III Red Hybrid Tomato seeds are an early season crop, these resilient plants should be ready for harvest 76 days from the sowing date. As a determinate crop, this hearty variety will produce a fibrous fruit texture in mid-to-late summer. Harvest La Roma III Red Hybrid Tomatoes before their skin feels too soft and once their red color is bright. In general, it's recommended to begin harvesting tomatoes once they start to turn in color. Harvest tomato plants by gently pulling the bright-red fruit from their calyx hat with one hand, while holding the stem with the other. Since La Roma Hybrid Tomatoes are known for their Italian cooking options, try making a rich roasted tomato dish baked with garlic, olive oil and sweet onion!

Growth Habit: |
Determinate - Determinate tomatoes are more compact, bush-type plants that set their fruit all at once and end the harvest. They won't continue to produce tomatoes after that. By planting multiple plants in intervals a week apart, you can continue to harvest for longer periods. |
Soil Preference: |
Well-draining, loose (sandy loam), slightly acidic (6.2 to 6.8), and moisture retaining. Too much nitrogen in the soil may lead to more foliage production and less fruiting. Tomatoes like more phosphorus and potassium than other vegetables. |

Also, watch for common diseases such as blossom end rot, fusarium wilt, powdery mildew, verticillium wilt, late blight, bacterial canker/spot, and tobacco mosaic virus. Most of these can be prevented by maintaining a regular watering schedule and avoiding overwatering. Regularly check your plants for pest damage throughout the season. For treating pest and disease problems, we recommend using an organic neem-based product. |
