Forcing Amaryllis and Paperwhites: A Guide for Holiday Blooms in Greenhouses

Quick Answer

To force amaryllis and paperwhites for the holidays, plant amaryllis 6 to 10 weeks and paperwhites 4 to 6 weeks before your target bloom date, then give them bright light and steady temperatures above 50°F (10°C). Pot amaryllis snugly with the top third of the bulb above the soil, and grow paperwhites in gravel and water or well-draining potting mix. A greenhouse from BC Greenhouse Builders makes forcing easier, with more natural light for sturdier stems, cooler nights that help blooms last longer, and bench space to stagger plantings for color from December into February.

10 Mistakes First-time Greenhouse Owners Make (and How to Avoid Them)

Quick Answer

First-time greenhouse owners most often buy too small, overlook winter sun when choosing a location, skip permit checks, and rush the foundation and installation. Once they're growing, overheating, overwatering, and missed seasonal maintenance are the most common struggles. Nearly all of these are easy to avoid with a little planning, and BC Greenhouse Builders can help you set up your greenhouse for success from day one.

Do You Need a Permit to Build a Greenhouse

Quick Answer

Whether you need a permit to build a greenhouse depends on a few key factors: the size of your structure, your foundation type, and whether it is freestanding or attached to your home. Many municipalities do not require a permit for greenhouses under 120 square feet on a non-permanent foundation, like pressure-treated wood, but larger builds, concrete foundations, and home-attached greenhouses are more likely to need one. Requirements vary by city and county, so it is always worth checking with your local planning department to confirm what applies to your project. At BC Greenhous Builders, our team can help you prepare everything you need, from wind and snow load specs to engineered drawings, if a permit is required.

Fall Greenhouse Prep: What to Do Before the First Frost

Quick Answer: 

Start before the frost hits. Once nighttime temperatures are consistently dropping into the single digits Celsius (upper 40s Fahrenheit), it is time to clean, check equipment, and add insulation, not wait for a frost warning to show up on the forecast.

Clear out and clean first. Remove finished summer crops, wash down any plants staying in for winter, and pencil in a deep clean for mid-November before things get too cold to tackle it comfortably.

Check your equipment, then seal in the heat. Inspect fasteners, vents, and fans while the weather still allows for it, then add insulation, thermal mass, row covers, or soil warming to hold onto heat as temperatures fall.

Ease off watering and switch crops. Cut back as growth slows down, and swap warm-season plants for cold-hardy crops like kale, spinach, and Swiss chard to keep the greenhouse productive right through winter.
