5-Step Plan for Sensible and Successful Greenhouse Gardening?

Quick Answer:

BC Greenhouse Builders recommends a five-step approach for sensible greenhouse gardening success:

• Grow only what you and your family love to eat – skip crops you won't enjoy no matter how healthy they are
• Measure your greenhouse space and calculate crop timing before ordering seeds to avoid over-purchasing
• Use your greenhouse for multiple purposes – propagation, early starts, and full-season growing
• Manage heat strategically to accommodate both cool-hardy greens and warm-loving crops like tomatoes and cucumbers
• Scatter quick-growing crops like arugula and radishes between larger plants to maximize space year-round
• Plan for succession planting to keep your greenhouse productive through overlapping seasons

BC Greenhouse Builders hears from customers who get excited about seed catalogs each year – sometimes too excited. It's easy to order hundreds of dollars worth of seeds only to realize you've bought far more than one greenhouse can handle. If you've ever faced a pile of seed packets wondering how you'll grow them all, you're not alone.

The good news? With a simple five-step plan, you can make your greenhouse growing sensible, successful, and truly enjoyable. This approach helps you grow what you love, avoid waste, and keep your greenhouse productive year-round through strategic planning and succession planting.

How Do You Decide What to Grow in Your Greenhouse?

The most important rule for greenhouse success is to grow only what you and your family actually love to eat. BC Greenhouse Builders customers report that forcing themselves to grow" healthy" vegetables they don't enjoy leads to wasted space, effort, and produce that ends up in the compost bin.

Before you buy a single seed packet, interview your family and make a list of the foods everyone genuinely enjoys. If you love tomatoes, peppers, and leafy greens, commit to growing those. If you tried collards once and hated them, skip them – no matter how nutritious the seed catalog says they are.

This principle applies to both full-season greenhouse crops and quick-succession plantings. When you focus on favorites, you'll actually harvest and eat what you grow, making your BC Greenhouse investment worthwhile throughout the year.

Popular crops many BC Greenhouse owners love growing:

• Tomatoes and peppers for full-season warmth
• Leafy greens like kale, bok choi, spinach, and arugula for cool months
• Root vegetables including beets, carrots, and radishes
• Cauliflower for succession planting from spring through fall
• Cucumbers for summer abundance

How Should You Plan and Measure Before Ordering Seeds?

Calculate your greenhouse space and crop timing before ordering seeds to avoid over-purchasing. BC Greenhouse Builders designs feature measurable growing space that you can map out using graph paper to plan realistic crop rotations.

Start by checking seed catalog descriptions for days to maturity. For example, cauliflower takes approximately four months from seed to harvest –starting indoors in February, transplanting to the greenhouse in March, and harvesting in June. Understanding these timelines helps you plan succession crops and avoid ordering more than your space can accommodate.

Planning Your Growing Space

Spacing guidelines are flexible in greenhouses. While cauliflower ideally wants four square feet per plant, BC Greenhouse owners successfully grow them closer together with slightly smaller (but still perfectly edible) heads. This flexibility allows you to maximize production without compromising quality.

Year-Round Succession Example

Many BC Greenhouse customers use this cauliflower succession schedule:

Remember that cool-climate crops don't actively grow during winterwithout supplemental heat, but they enter a dormant "hold pattern" while continuing to provide fresh harvests. This allows BC Greenhouse owners to enjoy freshvegetables even during the coldest months.

What Are the Different Ways to Use Your Greenhouse?

Your greenhouse serves multiple functions beyond just growing plants to maturity. BC Greenhouse structures accommodate propagation, early-start growing, and full-season cultivation all within the same space at different times of year.

Garden Heating Mat

Propagation Station

Set up a dedicated propagation area with a heat mat for rooting cuttings and germinating seeds. Once seedlings emerge, transplant them into trays andmove them to wire shelves inside the greenhouse. This protected environment lets you start flowers and vegetables weeks before outdoor weather becomes predictable.

Early-Start Growing System

BC Greenhouse owners install screws with eye-holes for hanging strawberry planters and flower baskets, allowing plants to graduate from shelf trays to hanging containers. This vertical approach maximizes space while plants mature before moving outdoors.

Permanent Bed Growing

Transplant permanent greenhouse crops like tomatoes, peppers, and cauliflower from trays directly into raised soil beds inside your greenhouse at least a month earlier than outdoor planting would allow. This extended season is one of the key advantages of BC Greenhouse structures.

Timing Your Starts

To find your area's last frost-free date, visit almanac.com/gardening/frostdates and enter your postal code. Plan to start outdoor flowers like asters and nasturtiums 4-6 weeks before that date. For full-season greenhouse crops, forget outdoor frost dates entirely – start tomatoes by mid-February and peppers by early March for greenhouse bed planting.

BC Greenhouse customers grow flowers for outdoor gardens too, starting China Blue asters to attract pollinators and multiple nasturtium varieties to attract hummingbirds. These start on propagation beds, move to greenhouse shelves, and finally transplant outside after frost danger passes.

How Do You Manage Heat for Cooland Warm Crops?

The key to year-round greenhouse productivity is managing heat strategically to accommodate both cool-hardy and warm-loving crops. BC Greenhouse designs allow you tocontrol temperature zones, but the timing requires planning to avoid forcing early-season greens into premature bolting.

The Cool Crop Challenge

Cucumbers crave heat, but hardy greens like arugula, spinach, bok choi, and mustard greens thrive in cooler temperatures. If cool-hardy greens overheat, they burst into bloom and the harvest ends abruptly. The solution is keeping the overall greenhouse cool while warming specific soil areas or seed zones.

Ground Heating Strategy

Many BC Greenhouse owners lay heating cables on ground beds in February as soon as the first patch of hardy greens finishes. This allows them to plant an early crop of potatoes in fabric grow bags over the heated soil while keeping the air temperature cool.

Use frost cloth (floating row cover) over tender crops to hold in localized heat and provide frost protection. Potatoes started this way can later move to greenhouse floor aisles, freeing up the warmed beds for cucumber transplants as overhead heating begins.

Transitioning from Cool to Warm

By late March, BC Greenhouse structures transition from cool-season to warm-season mode:

• Cold crops like greens and root vegetables finish their production cycle
• Heating systems warm both soil and air temperature
• Warm-loving crops like peppers, tomatoes, and cucumbers take over the growing beds

This transition timing maximizes both cool-season and warm-season harvests from the same greenhouse space.

Can You Maximize Space with Quick-Growing Crops?

Even with careful planning, there's always room for quick-succession crops between longer-growing plants. BC Greenhouse Builders customers report that scatter planting radishes and arugula significantly increases total harvest without requiring dedicated bed space.

Ultra-Fast Crops for Succession

Arugula and radishes go from seed to table in just 2-3 weeks. BC Greenhouse owners have harvested radishes in as little as 18 days during warm soil conditions. The warmer your greenhouse soil, the faster these quickcrops mature.

For radish varieties that mature in under 30 days, check specialized seed catalogs like West Coast Seeds.

How to Scatter Plant

Don't assign dedicated beds to quick-growing crops. Instead, sprinkle seeds between larger plants that are spaced far apart due to their ultimate size:

• Cauliflower ideally needs 4 feet between plants, leaving abundant empty space early in the growth cycle
• Tomatoes and cucumbers need approximately 3 feet each later in the season, but offer room for scatter crops in March, April, and May
• Any large crop with wide spacing creates opportunities for quick succession plantings

Year-Round Productivity

This scatter planting approach keeps BC Greenhouse structures productive throughout the entire year. While larger crops mature slowly, quick-growingvarieties fill gaps and provide regular harvests. The season of overlapping crops creates continuous abundance rather than boom-and-bust cycles.

BC Greenhouse growing is about enjoying your hobby year-round. Experiment with different combinations, play with succession timing, and have fun discovering what works best in your space and climate.
