FAQ
What size containers are these plants suitable for?
Most of the listed plants thrive in containers ranging from 15-30cm in diameter. Larger greenhouses will allow for more substantial planting, but smaller containers are perfectly adequate for herbs and bedding plants.
Do I need a particularly large greenhouse to grow these?
No, this selection is designed for smaller greenhouses or even just starting seedlings indoors before transplanting them outdoors. Many varieties can be successfully grown in structures up to 90cm x 120cm.
What kind of soil should I use in my containers and greenhouse?
A good quality, peat-free potting mix is recommended for optimal drainage and nutrient retention. Ensure the mix is suitable for seedlings or established plants depending on your chosen varieties.
Are these seeds easy to germinate?
Many of the included seed packets specify germination times and conditions, but generally, most annuals and hardy herbs are relatively straightforward to sow, particularly when starting indoors.
How much sunlight do these plants need?
The majority of plants listed require at least 6 hours of direct sunlight per day for optimal growth. However, some varieties can tolerate partial shade conditions, check the individual plant descriptions carefully.
What’s the best way to water my plants in containers and a greenhouse?
Water regularly, especially during hot weather, allowing the soil to dry out slightly between watering. A small greenhouse will require more frequent watering due to humidity.
Can I move my seedlings from a greenhouse to an outdoor container?
Yes, you can! However, acclimatise seedlings gradually to avoid shock by slowly increasing their exposure to natural sunlight and outdoor temperatures over 1-2 weeks before transplanting.
Are there any particular plant combinations that work well in containers?
Consider companion planting – herbs like basil and rosemary thrive alongside tomatoes. Combining different coloured annuals creates a more visually appealing display within your chosen container or greenhouse.
What are the best seeds for beginners to grow indoors?
Lettuce, radishes, and spinach are all easy-to-grow options perfect for starting seedlings in a greenhouse or on a windowsill. These plants germinate quickly and provide rewarding harvests for novice gardeners.
How do I care for my plants within the greenhouse environment?
Regular ventilation is key to preventing fungal diseases within a small greenhouse. Monitor temperature and humidity levels, and ensure adequate drainage to avoid waterlogging.
