Gary in Hawaii has brought to notice an interesting topic of pollinators generally. I do not have the night moth in my area which pollinates Tulbaghia, which isn't surprising since I've taken the plant away out of its natural habitat of South Africa. But I would have thought that one of our local pollinators would step in & do the job but no. The only night moth I know of here is Spodoptera picta, the Lily Borer, Australia's answer to Brithys crini syn. Brithys pancratii or Amaryllis Caterpillar. But looking on the brightside, since Tulbaghias are rather promiscuous & I'm growing many species, then at least my Tulbaghias won't hybridise without my intervention. Organic & permaculture gardeners recommend planting an area of between 1% & 5% of one's land with a nectar source for beneficial & pest-controlling insects for good results. This can be along fencelines or garden edges. Planting particular flowers & herbs, known as insectary plants, has been proven to improve the natural balance & reduce pest outbreaks. The insectary plant area should be allowed to go somewhat wild & provides year-round nectar, pollen & habitat for native & introduced beneficials, e.g. predatory mites & wasps, ladybirds, lacewings, hoverflies, tachnid flies & predatory beetles as well as bees. Insectary plants include red clover, lucerne, sweet alice, dill, caraway, coriander, cosmos, buckwheat, baby's breath, marigold & Queen Anne's Lace. Every little bit helps.
