Aphids, also known as greenfly or blackfly, are tiny, sap-sucking bugs that can occur on most plants, particularly on soft young growth. There are actually more than 500 species of aphid in the U.K., varying in colour from green and black to also yellow, brown, and orange, and in size from 1mm to 7mm long.
Aphids need warmth to flourish, so in the garden this limits their lifecycle to spring and summer. However, indoors in the home, greenhouse or conservatory, aphids can occur at any time of year. Many types of aphid feed only on specific plants, so an infestation on one plant doesn’t necessarily mean that it will affect all of your plants.
Aphids are a common garden pest that can quickly infest and damage baby sage plants These small, sap-sucking insects attack new growth and feed on plant juices, causing distorted leaves, stunted growth, and spread of disease While aphids on mature sage plants can be annoying, an aphid infestation on a baby sage can be devastating and even fatal. The key to protecting your baby sage from aphids is early detection, prompt removal, and prevention of recurring attacks.
Identifying Aphids on Baby Sage
The first step is learning how to identify aphids on your baby sage. Aphids are typically green or black soft-bodied insects less than 1⁄4 inch long. They tend to cluster on the undersides of leaves or along the tender stems of new growth. Signs of an aphid infestation include:
- Sticky honeydew residue on leaves
- Curled, yellowing, or distorted leaves
- White cast skins shed during molting
- Stunted plant growth
Ants may also be present, as they feed on the sugary honeydew secretions from aphids. Carefully inspect the undersides of leaves to spot these sap-sucking pests early.
Removing Aphids from Baby Sage
If you detect a small aphid colony, manually removing them can help eliminate the infestation before it gets out of control. Here are some effective manual removal techniques:
-
Hand picking: Use gloved fingers or a damp cloth to gently crush or wipe away any visible aphids. Check entire plant for colonies.
-
Pruning: Clip off heavily infested leaves and new shoots and dispose of properly. Avoid composting infested trimmings.
-
Hosing Use a forceful spray from your garden hose to blast aphids off plant Focus on undersides of leaves
For heavy infestations, insecticidal soap, horticultural oil, or neem oil can help kill aphids through contact. Always follow label directions. Repeat applications may be needed. Avoid using harsh chemicals as they can damage young sage plants.
Preventing Aphids on Baby Sage
Stopping aphids before they establish colonies is the best approach. Here are some tips to keep aphids off your baby sage plant:
-
Attract beneficials: Ladybugs, lacewings, hoverflies, and other beneficial insects prey on aphids. Plant flowers like yarrow or dill to attract them.
-
Practice crop rotation: Avoid planting sage in the same location as previous years to disrupt pest cycles.
-
Use row covers: Cover young plants with fabric row covers to form a physical barrier against pests.
-
Avoid over-fertilization: Excess nitrogen can cause rapid, tender growth that attracts aphids.
-
Use reflective mulches: Silver-colored plastic mulch can deter aphids from landing on plants.
-
Clean up debris: Remove weeds and garden debris to eliminate aphid hiding spots.
-
Check transplants: Inspect purchased plants for aphids before bringing home. Quarantine new plants.
-
Water adequately: Drought-stressed plants are more vulnerable to pests.
-
Spray neem oil: Use as a dormant spray to coat plant in protective barrier against aphids.
Catching an aphid infestation early and taking quick action is key to protecting your vulnerable baby sage plant. Combine manual removal methods for light infestations with insecticidal soaps or horticultural oils for heavy colony establishment. For long term protection, focus on preventive measures like beneficial insect habitat, crop rotation, and soil health to create an environment unfavorable to aphids. With vigilance and early intervention, you can keep your baby sage flourishing, aphid-free, and ready for harvest.
Controlling aphids without chemicals
The chances are that, by the time you’ve found greenfly or blackfly on your garden plants, the predators have, too. So bear in mind that removing aphids will likely kill beneficial insects such as ladybirds and lacewings, as well as aphids. These predators are not present indoors so you will need to control aphids yourself:
- Wash off greenfly with a jet of water from a hose
- Hand-squash small infestations
- Use biological controls, which involve buying live predators into the home or greenhouse to deal with aphid infestations

Why are aphids a problem?
Greenfly and blackfly are a natural part of the garden ecosystem and a vital source of food for many species of bird, including house sparrows. They’re only a problem if they occur in large numbers. Large infestations can weaken plants and cause curling or distortion of affected growth. This can sometimes eventually kill the plant, especially young ones. Some aphid species transfer virus diseases between plants – there are many viruses that cause a range of symptoms including mottled, streaked or distorted foliage, and weak growth. Viruses aren’t curable so infected plants should be destroyed. An additional problem caused by greenfly and blackfly is the sticky substance they exude, known as honeydew, which can become infested with black mould – this stops leaves photosynthesising and inhibits plant growth.

Will a plant recover from aphids?
How do you get rid of aphids on plants?
If you spot a few aphids on your plants, the minor infestation can be successfully remedied with a strong stream of water from the hose from a quality spray nozzle like the Green Mount Heavy-Duty Water Nozzle, a top pick in our researched guide to the best hose nozzles. Spray water all over the plant, making sure to target the undersides of leaves.
Does honeydew kill aphids?
In great quantities, it may drip off the plant. A side effect of this honeydew is that it attracts sugar-loving ants. (Ants have been known to protect aphids, even going so far as to carry them from plant to plant and overwintering their aphids in their own nests!)
Where do aphids hide?
Aphids like to shelter on the undersides of leaves and hide deep in the centers of plants like lettuce and broccoli, so get in the habit of inspecting your plants regularly, especially during periods of new growth. 1. Avoid over-fertilizing your plants.
Can neem oil kill aphids?
Typically, they are unable to find their way back to the same plant. Neem oil, insecticidal soaps, and horticultural oils are effective against aphids, but these substances need to come into contact with the aphids in order to work. Be sure to follow the application instructions provided on the packaging.
