It’s summertime, and the weather couldn’t get any better! Your garden is flourishing into a mass of texture and color with numerous visiting butterflies and hummingbirds. Not only that, but the apricots and plums are sweeter than ever! 

Then the winter rolls around, and the blueberries and peaches replace the summer fruits. An idea comes to you: why not build a greenhouse!

Any kind of plant can be grown in a greenhouse, but some need more attention than others. In fact, some basics can influence any plant. These include the age and type of seed, pH level, water supply, humidity level, temperature, and amount of sunlight and shade the plants are receiving.

If any of these basics are slightly altered, expect slow or no growth at all! Consequently, easy-to-grow plants are the best to start with as they don’t have strict requirements and are somewhat tolerant to mishaps.

Additionally, lavender is tolerant to some pests and diseases and is best harvested in the morning.

Additionally, make sure to keep the soil moist till germination. Nigella plants are preferably grown in sunny areas, although they grow fine in shady ones too. Remember, these plants flourish better if sown directly instead of being transplanted. 

These blue beauties are pest-free since they don’t attract insects and don’t last long enough to catch any diseases.


Tarragon seeds for planting

If you want to add some color to your greenhouse, tarragon is a two-in-one! This herb blooms attractive flowers. Tarragon can be grown from seeds, seedlings and cuttings.

In terms of planting, place up to 6 seeds in a pot and apply moistened potting mix. Place the pot under direct sunlight and allow sufficient airflow. Due to its sturdy root system, tarragons can tolerate dry and desert-like environments up to two years. 

When harvesting, you may cut the leaves and flowers. 


Kale seeds for planting

Kale is a delicious antioxidant green for salads and other dishes. It’s one of the most tolerant and disease-resistant plants. It practically requires no attention at all. 

To keep them healthy, routinely hoe the weeds and remove any yellow leaves around the plant’s base. Place them in a spot with part sunlight and part shade. The tip will keep growing new leaves for months, so make sure to pick out the ones at the bottom first.

Star Anise

catnip cat grass seeds for planting

Catnip is an enjoyable treat for kitties and a medicine source for us. It could be grown from leaf tips and seeds. Keep this plant in sunny areas with a constant water supply and drained soil. Although catnip attracts some beneficial pests, the leaves naturally repel insects if rubbed on the skin. 

Protect the plant with wire meshes from any neighboring cats. 


eggplant seeds for planting

Eggplants are best grown in warm environments. Plant the seeds in raised beds with fertilized soil. You may also apply a thin layer of potting mix to prevent dryness and disease. 

Eggplants can be harvested after 16 to 24 weeks when the skin is looking bright and smooth. 


Thyme seed for planting

Thyme is a flavorful herb that only needs 14 to 28 days to grow. They need a temperature around 21°C, making a greenhouse the ideal place for them. 

To plant thyme, scatter the seeds one foot apart and get them closer to 6 inches apart only when the seedlings have developed. Harvest the plant before the flower blooms by cutting the herb 2 inches from the top. The plant will regrow a second batch of thyme after.


carrot seeds for planting

Carrots are one of the best root crops to grow in a greenhouse. They can be planted at any time of the year and endure frost very well. 

To plant them, prepare deeply-tilled sandy loose soil and allow the seeds to dig their way through. Make sure the soil isn’t too thick unless you want short round carrots. Carrots attract several pests and diseases that no registered pesticides can be used for. Therefore, check the seed packet very well to use disease-free seeds only. 

Although it depends on the environment, carrots usually require 2 to 4 months and can be harvested early.
