What Is The Temperature For Growing Lettuce From Seed In The Greenhouse

If you’re not sure what the temperature is for growing lettuce from seed in the greenhouse, monitor your thermometer and aim for 70 to 75°F. A dilemma that a gardener might encounter with indoor cultivation of greens is what temp growing lettuce from seed in greenhouse works best. However, you don’t need to be intimidated by this crop because you already have a head start planting it in a greenhouse. 

The hardiness zone will help you know if lettuce will grow well in your state. In particular, lettuce crops will thrive best in zones 4 to 9, so keep this in mind before considering their cultivation. However, the greenhouse provides control over the indoor conditions, so with proper planning and maintenance, you can have fresh and healthy greens at your garden easily.

What Is The Temperature For Growing Lettuce From Seed In The Greenhouse: Pointers To Consider

What determined the optimal temperature for growing lettuce from seed are seed germination and greenhouse condition. Additionally, always consider your growing zone or hardiness zone so you can make the necessary adjustments customized to your location. Each state has different climates and temperatures, so you may have to perform other greenhouse practices to maintain optimal conditions. 


Seed germination

When growing lettuce from seeds, it’s crucial to remember that its germination is significantly affected by the temperatures. You want to maintain the greenhouse at 70 to 75°F for optimal germination, although the seeds can germinate even at 35°F. Still, freezing conditions can injure the lettuce crops, especially when they have not yet hardened. 


Greenhouse condition

While lettuce is very adaptable in cold growing conditions, it’s still essential to maintain the greenhouse at 60 to 65°F for their growth. The crops will flower and seed at 70 to 80°F, and lettuce can withstand 80 to 85°F for a few days if necessary. But because you are growing from seeds, the temperatures are more influential in encouraging growth. 

For maintenance, the daytime temperatures that will work best for lettuce is 60 to 65°F and 50 to 55°F at night. It would also be helpful to choose a lettuce variety that is appropriate for your expected conditions. For example, if your location has a warmer climate, what’s suitable for you are heat-tolerant varieties. 

For greenhouses, extensions in universities recommend Leaf and Bibb lettuce varieties. For the former, Ruby Red, Grand Rapids, and Waldmann’s Dark Green are popular, while Mirlo, Roxy, Rosaline, and Cegolaine are common Bibb varieties in the greenhouse.


When To Grow Lettuce In A Greenhouse?

Since you’re starting from seeds, begin sowing as soon as the ground is workable or above 40°F. The soil temperature at 55 to 65°F will encourage germination as early as seven days. You can even have an earlier crop using a greenhouse by sowing before your last spring frost date. 

In some states like North Carolina, it’s possible to sow both in spring and fall. However, the Department of Horticultural Science of NC State Extension mentioned that spring lettuce also tends to fail, so it’s best to use transplants for this period. On the other, direct seeding is best for fall crop lettuce, but since it can get hot and dry, always check your temperature and irrigation in the greenhouse.

In eastern North Carolina, direct seeding is typical in late January and early February, while those in the west start in late March and early April.  If you’re doing a fall crop, sow 80 days before the first hard freeze. Depending on your area, you might even be able to plant a second crop in early winter. 


Other Lettuce Growing Requirements


Soil, feeding, and watering

Lettuce will grow best in a fertile, loose, and loamy soil with good drainage and pH of 6.0 to 7.0. You can sow the seeds half an inch deep before covering with another inch of soil. As for feeding, New Mexico State University mentioned using a balanced fertilizer before planting and weekly nitrogen feedings. 

What about the watering requirements of lettuce? In the greenhouse, it’s best to use a misting system to avoid overwatering the crops. A good measure is an inch of water every week so that you’ll get tender leaves.



Allocate four to six inches of space between rows and thin the plants with an inch or two between them. If you’re growing lettuce seeds indoors for transplants, later on, a good ratio is 6 ounce of seed per 300 square feet of the bed. This ratio will give you enough operations for an acre. 

Lettuce also works excellently in companion planting in the greenhouse. Chives or garlic can help deter aphids, so consider having rows of these crops in between your lettuce. You can also use blocks and containers for growing lettuce in the greenhouse, but pay attention to their root growth direction.  



Lettuce is a healthy and delicious staple for our meals, and cultivating them indoors is even accessible both for commercial and personal use. If you’re interested, do you know what the temperature for growing lettuce from seed in the greenhouse is? A greenhouse maintaining 70 to 75°F is best for optimal germination, but always remember the different lettuce requirements for a successful growing season.

This article will teach you the ideal conditions and practices to keep your carpet roses blooming happily. 


In general, carpet roses are easy to grow and are relatively low-maintenance. However, the emphasis is necessary on knowing the variety you have and adjusting the plants’ practices and requirements accordingly. 


Factor #1. Location

The first consideration to ensure proper care for carpet or groundcover roses is in the ideal growing environment. Remember that even though groundcover roses are not picky in sites, they should still be in an optimal location to thrive. You can determine the ideal location of your carpet roses depending on their type

For example, some groundcover roses prefer full sun, but others will thrive in partial sun. You also want to plant them in well-draining soil because these plants are prone to drowning. After ticking these boxes, allocate enough space for the carpet roses to keep them from getting overcrowded that can cause problems over time. 


Factor #2. Maintenance

The second factor when caring for carpet roses is the practices in maintaining them. To start, remember that it’s crucial to plant them in a well-draining area. Overwatering the plants or leaving them in standing water can drown the plants or encourage root rot. Always check the ground if the roses need watering and amend the soil to improve its structure.

Carpet roses will also benefit from fertilizers. You can boost the plants and encourage them to fully cover the ground by feeding above and below the roses. Check the label instructions of your fertilizer and put your plants on a schedule for fertilizing regularly. 

Do you prune carpet roses? Depending on what type you have, some roses will benefit from pruning. You can cut the stems after flowering to keep the roses from overgrowing their area and maintain a tidy look. 


Factor #3. Common problems

Carpet roses, much like other groundcover plants, are prone to pests because of the large surface area they have. Therefore, prevention is vital to keep the pest population at bay. Gardeners often use insect spray or fungicides on the carpet roses to keep off insects or fungi. 

You can also practice preventative measures such as isolation of new plants and immediately removing plants with pests or diseases to prevent the spread. Always practice proper hygiene and sanitation to avoid bringing pests into the area. More so, maintain the ideal environment to discourage insects’ reproduction like aphids or the development of diseases like powdery mildew. 

Unlike other groundcover plants, carpet roses don’t have enough foliage to smother weed. Therefore, you want to use landscape fabric with drip irrigation on top to deter weed growth. You can also mulch under the systems or add a pre-emergent herbicide in early spring or fall to manage weeds.



How To Grow Carpet Roses

You can propagate carpet roses by rooting sections of the stem of a parent plant. Carpet roses typically develop rooted stems in spring or fall that you can dig up and repot. However, remember that the best propagation method will vary on the type of roses you have, 

You may also purchase potted ground cover roses, and you can transplant them in a bigger container or onto the ground outdoors. You can again grow bare-root carpet roses after the frost in the garden the same way you would when planting other roses. Amend the soil with organic matter and water the plants after putting and firming them in place. 

Because of their low-growing habit, you can have many uses for carpet roses. You can use them as borders or barriers for paths and driveways, add texture to a slope or wall, or fill a bed in the garden. However, be prepared that these plants can become leafless during the dormant season. 



One of the best groundcover plants to consider is carpet roses. However, you must know how to care for carpet roses to keep them healthy and looking tidy. To start, grow them in an ideal location to lessen the chances of developing drawbacks and problems. 

You can check the type of roses you have to know where is the best place to grow them. Once you have ensured the ideal location, maintain your plants by watering and fertilizing regularly. Be mindful not to overwater your plants as this can drown them, and you can also boost growth by feeding according to the label. 

You can also keep the roses from overgrowing their space by pruning after the flowering season. Lastly, do the necessary preventative measures to keep the roses from acquiring pests and diseases. Use fungicide or insect spray to keep fungi and pests at bay and maintain stable conditions to discourage growth and spread.
