![]() All have an inflorescence with lots of tiny, accessible flowers. Queen Anne’s lace, wild parsnip, fennel, dill, cilantro/coriander, caraway and others are quite attractive to beneficials. The Umbelliferae, or carrot family, contains many such species which are frequently included on lists of good plants for insects. Most of the flowers with these characteristics are concentrated in a few plant families. These types of flowers are frequently included in lists of flowers to plant for beneficials, or are in commercially available “insectary seed blends.”Ĭilantro flowers attract many small insects. Each individual flower is shallow (not tubular), and has exposed nectaries (although you probably can’t see that!) so it’s easy for the fly to gets its tiny mouthparts to the good stuff. But to a little syrphid fly, less than ¼ inch long, it’s a smorgasboard of hundreds of tiny nectar-producing flowers. Take a look at a Queen Anne’s lace “flower” – it’s a large inflorescence (an umbel, technically speaking). The flower of Queen Annes lace (L) is made up of many small flowers (R). ![]() Many of these small flowers come in big packages that we’d call a single flower, but are actually lots of tiny individual flowers grouped together. The best flowers for these small natural enemies are also small. Many of the natural enemies that can benefit most from floral resources are very tiny wasps, which will get lost in a big flower. However, the size and shape of a flower limit the kinds of insects that can access its pollen and nectar. Whether or not planting a specific flower will actually help reduce the abundance of a problematic garden pest depends on how effectively the flower brings in the more effective natural enemies.įlowers provide pollen and nectar as a sort of bribe to induce insects to transfer pollen from one flower to the next and cause pollination. Predatory bugs (such as nabid bugs, minute pirate bugs or twospotted stink bugs) can also be found on flowers, but they’re generally there to feed on thrips or other prey on the blossoms rather than feeding on the flowers themselves. Not all flower visitors are there for the nectar! Some of the many beneficial insects that visit flowers include lady beetles, green lacewings, syrphid flies, tachinid flies, sphecid wasps and various parasitic wasps. By providing nectar and pollen, flowers can attract and keep the natural enemies of many pests in the home landscape, enhancing natural or biological control. Many natural enemy adults – particularly tiny wasps and flies – visit flowering plants to obtain nectar and pollen. The rest of the Canada plants on the traditional planting day of Victoria Day long weekend, generally around May 24.Many natural enemies visit flowers for the nectar and pollen. In the Pacific Northwest, sow the seeds of warm season crops in the late April to the beginning of May. If it is too cold they won't grow, flowering is delayed or they will drop off without being pollinated, which delays fruit formation. Seeds need temps above 10° C, (50° F), and will rot in cold soil of 12 ☌ (53° F) or less. Quick growing hot crops such as cucumbers, melons, corns and beans can be sown outside after the danger of frost has past, however, tomatoes and peppers are best sown indoors to ensure a bountiful harvest before the weather cools and rain returns in autumn. Once the danger of frost has passed, plant tomatoes, cucumbers, melons, corns, beans and other warm season crops that are easily killed by frost. *corn,*cucumbers, *beans, *squashes (zucchini, acorn, cucumbers, watermelon, cantaloupe), *peas, *broccoli, *cauliflower, *Brussels sprouts, *chard, *lettuce, *onions, shallots, chives, *celery, radishes, carrots, parsnips, dill, beets, rutabaga As always, refer to the seed packet to when and how they should be planted. Ones with an asterisk* can be sown earlier indoors, then hardened off and planted outside as transplants. ![]() Starting seeds indoors also gives you more control over their environment: temperature, soil moisture, lighting and there's no slugs, cutworms or bugs! However some plants don’t transplant well as they have tap roots that are easily damaged such as carrots, beets, turnips, parsnips and other root crops.īelow is a list of plants suited to direct seed. ![]() Some seeds can be started both inside and outside such as cucumbers, sunflowers, beans, sweet peas and corn. The term ‘direct seeding’ means to sow the seeds outside in the soil where they are to grow. Lily-of-the-Valley Shrub, Pieris japonica
