What’s on the show today?Clouds of pests in the Plant Doctor segment, growing an ancient grain in Vegetable Heroes. Five senses gardening today’s it’s all about smell in Design Elements and the sex of flowers in the Talking Flowers segment with Mercedes.
Maybe you’ve had that in the past and haven’t been successful in removing them from a particular plant.
|Sweet Potato Whitefly|
Let’s find out .
Are you surprised that there’s several species of whiteflies?
Shooing them away every time you go out into the garden isn’t successful.
Symptoms:What To Look For:
- Don't confuse them with scale, because the whitefly juvenile stage can look like scale.
- If your not 100% sure that it's whitefly larvae that you're looking at,there are other symptomes to look for.
- Whitefly are sap suckers and will ssuck the chorophyll ( green part) out of the leaves.
- Whitefly also produce mass of honey dew to which, sooty mould will settle.
- You must take action because whiteflies suck the sap out of your plants’ leaves.
- Botanical oils work the best but you need to be able to spray under the leaves.
- Using a pump action sprayer with help with the underneath the leaves.
- Do a follow up spray 3-5 days apart to get the juvenilies.
- Neem is approved overseas for this problem on edibles but only on ornamentals in Australia.
- Encourage lacewings into your garden because the love whitefly as much as they love aphids.
- Quinoa is easy to grow, which shouldn’t surprise you being related to a weed.
- Direct sow the seeds in late September to the end of October, while night temperatures are still cool.
- Keep in mind. Quinoa seedlings aren’t frost tolerant.
- The best soil temperature for germination is 18-24°C.
- Anything over 320 C and it won’t germinate.
- Keep the soil most otherwise your seeds will fail to germinate.
- Sow the seeds about 5mm deep (that’s ¼” in the old scale).
- That means you’re barely covering the seeds, and thin then out when they reach 10 cm in height.
- Here’s a tip: because they look like weeds when they first emerge, show them in rows so you don’t confuse them with real weeds.
- If you’ve got the conditions right, then the seeds should germinate in 4-10 days.
- The spacing should be around 25-35cm (10-14″) between plants.
- Perhaps you want to grow them for baby leaf production, then plants can be spaced closer together.
- They’re slow growing for the first 10cm then seem to take-off after that.
- Liquid feed them if you want to give them a kick along.
But if you want a really perfumed garden, you might want to think about including plants in the garden that you don’t necessarily need to crush, rub or touch to inhale their sweet perfume.
What does that mean you should do?
Let’s find out.
Some suggestions for introducing more perfume into the garden that will pervade the whole garden.
- Sweet Olive, (Osmanthus fragrans),
- Angel Trumpets,
- Michelia varieties, (now included in the Magnolia family) like Port Wine Magnolia; Magnolia Chamopaca, and many others.
- The pollinator visits the flower and brushes past the stamens.
- When the pollinator visits the next flower, the pollen is rubbed onto the sticky stigma.
- If it's the right type of pollen ( fits the opening) then the flower will be pollinated resulting in some sort of fruit.
