A garden is full of life. It’s natural to have all kinds of insects buzzing around. Flies, beetles, bees, there are good and bad. So what about spider mites? Are they good bugs, or are they harmful to plants?
The African mallow shrub (Anisodontea capensis) is admired for its colorful, hibiscus-like blooms. However, these ornamental plants can fall victim to destructive spider mites. As a gardener, it’s crucial to know how to recognize and control spider mite infestations in African mallow shrubs. By implementing prompt treatment measures, you can restore the health and vitality of your prized shrubs.
Identifying Spider Mite Damage
Spider mites are tiny pests, barely visible to the naked eye. But the damage they inflict is quite apparent. Here are the telltale signs of spider mite infestation:
-
Webbing on Underside of Leaves: Spider mites spin fine, silky webs on the undersides of leaves. This is where they lay eggs and feed.
-
Speckling The mites’ feeding causes yellowish or white stippling on leaf surfaces The stipples become more pronounced over time
-
Bronzing: Heavily infested leaves turn yellowish-bronze and may shrivel up.
-
Stunted Growth: Spider mite damage inhibits nutrients and moisture absorption, leading to poor growth.
Effective Treatment Methods
If you spot spider mites on your African mallow, take action right away. Here are organic, eco-friendly methods to eliminate these pests
Hose Them Off
A strong spray from the garden hose can wash away spider mites and their webbing. Focus the water jet especially on the undersides of leaves. Repeat every few days until mites are gone.
Apply Insecticidal Soap
Insecticidal soaps made from potassium salts of fatty acids can kill mites on contact. Spray all leaf surfaces thoroughly. Avoid applying during the hot midday sun.
Release Predatory Mites
Natural predators like predatory mites and Persimilis attack and eat spider mites. Introduce them to establish populations that keep pests under control.
Use Neem Oil
Neem oil’s azadirachtin compound disrupts the mites’ growth and reproduction. Mix neem oil with water and a bit of liquid soap and spray onto affected shrubs.
Apply Diatomaceous Earth
This powdery substance comprised of fossilized algae acts as a desiccant against soft-bodied insects. Lightly dust it onto leaves to destroy spider mites. Focus application on leaf undersides.
Prune Out Infestations
Severely infested leaves and stems can be pruned out. This removes mite populations and prevents them from spreading. Discard pruned material immediately.
Preventing Reinfestation
Once spider mites are eliminated, be vigilant about preventing their return:
-
Check plants frequently for signs of mites, especially the leaf undersides.
-
Keep African mallow shrubs healthy with proper soil, sunlight, water and fertilization. Healthy plants better withstand pests.
-
Promote air flow and plant spacing to discourage mites which prefer crowded, humid conditions.
-
Attract predatory insects like ladybugs and lacewings which feed on spider mites. Plant nectar-rich flowers to draw them in.
-
Hose down plants regularly to deter mites and disrupt their life cycle. Focus on leaf undersides.
-
Apply neem oil or insecticidal soap preventively every 2-3 weeks during spider mite season.
Spider mites can wreak havoc on African mallow shrubs. But through close monitoring and integrated pest management practices, the damage can be contained. Implement organic treatments at the first sign of infestation before it escalates out of control. With prompt action, your beloved African mallow shrubs will once again be vibrant and thriving in your garden.
Are they a beneficial spider or a harmful mite?
While spiders can be beneficial in outdoor gardens, spider mites are harmful to plants. Like thrips, they pierce plant cells and suck out the juices.
Spider mites spin webs and cover the leaves to protect themselves and their eggs. They are hard to spot and often aren’t detected until there is noticeable leaf damage.
These microscopic arachnids reproduce rapidly. Spider mites go through a larval stage and two nymph stages. They usually overwinter in the egg stage. Each species varies, but eggs typically hatch in 3 days.
One female spider mite can lay up to 300 eggs in her lifespan and live for two to four weeks.
Their lifecycle can be as little as two weeks under the right conditions, which include temperatures over 90ºF.
What are Spider Mites?
Spider mites are tiny arachnids. They are less than 0.4 mm and have four pairs of legs. The two-spotted mites we see on our plants are the most common spider mites. It gets its name from the two dark spots on either side of its body, which are accumulations of its body waste. But you have to have a powerful microscope to see it.
