Sun Annuals

Annuals for Sun

Here at Belgian, we transplant and grow thousands and thousands of Annuals, just for you! And to keep things running smoothly, we’ve organized our Annual Greenhouses into Sun (#12 to 20) and Shade (#8 to 11). So let’s take a look at the latter, shall we?

What Do We Mean By “Sun” Annuals?

All plants need sunlight, and some require more of the sun’s rays than others. Varieties that need and thrive on 6+ hours of direct sunlight are deemed “Sun” Annuals, while those that would cook and burn in such conditions are for “Shade”.

Full Sun vs Part Sun

We try to have as much plant care information on our Annual signs as possible; you may see some state “Full Sun” or “Sun to Part Sun” but what exactly does this mean?

Full Sun = Sun all day with little to no shade; minimal shade that does not exceed a few hours, either in early morning or late afternoon; typically a south- or west-facing location

Part Sun = Direct sun shining on the location for approximately half the day, particularly in the afternoon when sunlight is strongest; light filtering through a deciduous (maple, oak, etc) tree canopy for most of the day can be considered Part Sun

Highest Sun Energy Levels: 11am to 4pm

East Facing = Morning Sun            (good light, weaker energy levels)
South Facing = Full Sun                   (ideal vegetable growing location)
West Facing = Afternoon Sun      (excellent light with strong energy levels)

Remember that the sun’s energy is less intense in the morning and gets stronger as the day progresses, with the highest levels reaching your garden between 11am to 4pm. So if you need to reach for the SPF 80 to garden, chances are you’ve got a Full Sun location.

More Sun = More Water (Usually)

All Annuals will need regular and deep watering, and Sun Annuals typically dry out faster due to, well, the sun. Hanging baskets, planters, window boxes, and other container Annuals will also dry out faster, so expect to water all of these once or even twice a day in the summer heat waves – check your plants every day! To reduce soil evaporation, water in early morning before the sun hits those high energy levels; during the high heat of summer, you may have to add watering around supper time to allow the leaves to dry off before nightfall. Adding mulch to your garden beds will also help keep the water in the ground rather than vanishing into thin (hot) air.

Frost Warning!

All Annuals, including Vegetable plants, CANNOT tolerate frost or cold temperatures below 10°C! They should only be planted outside once the threat of such conditions has passed, usually around the May long weekend. If you choose to buy your Annuals early, be sure to keep them indoors and give them the light, water, and warmth that they need until it is safe to plant outside. You don’t want to risk any cold damage by relying on an unheated garage/shed, and having them under a porch roof or overhang still leaves them exposed on all other sides. Protect your investment: keep them inside.
