Greenhouses

1. What size should a greenhouse be?

The choice depends on available space, the types of plants being grown, and budget considerations. Larger structures offer more versatility but require more space and investment, while smaller growhouses provide a cost-effective solution for beginners or those with limited space.

2. What materials are best for greenhouse construction?

Aluminium frames with glass or polycarbonate panels are popular choices. Aluminium is durable and low-maintenance, glass provides excellent light transmission, and polycarbonate is lightweight, shatter-resistant, and offers good insulation.

3. How can temperature and humidity levels be maintained?

Ventilation systems such as roof vents, louvre windows, and automatic vent openers help regulate temperature. Shading solutions prevent overheating, while monitoring devices assist in maintaining appropriate humidity levels.

4. Is planning permission required for a greenhouse in the UK?

Most domestic greenhouses fall under permitted development and do not require planning permission. However, it is advisable to check with the local planning authority for specific regulations.

5. What foundation is suitable for a greenhouse?

A solid, level foundation is essential for the stability of a greenhouse. Options include concrete slabs, paving slabs, or a perimeter base with a gravel floor, ensuring durability and longevity.

6. How can pests and diseases be prevented in a greenhouse?

Regular maintenance is key: removing plant debris, ensuring good air circulation, and avoiding overwatering can help reduce risks. Regular inspections of a greenhouse allow early detection and treatment of any pest or disease issues.

7. What heating options are available for a greenhouse?

Electric heaters, paraffin heaters, and gas heaters are common choices for keeping a greenhouse warm. Insulating with bubble wrap can also help retain heat. The ideal heating solution depends on budget and environmental considerations.

8. How can space be maximised in a small greenhouse?

Vertical space can be utilised with shelving and hanging baskets. Tiered staging and compact or dwarf plant varieties help optimise the available area.

9. What are the benefits of using a greenhouse?

Greenhouses extend the growing season, protect plants from adverse weather conditions, and create controlled environments for optimal plant growth, enhancing the gardening experience.
