Common Pests & Diseases
























- Sporulation begins (reproduction of the fungal spores), and tiny spots appear on leaves.
- Placement is often random and scattered as diseases are spread through raindrops.
- May appear on lower leaves and the interior of the plant where humidity is higher.
- Brown spots enlarge and grow large enough to touch neighboring spots to form a more prominent blotch.
- Leaf margins may turn yellow.
- Tiny black dots (fruiting bodies of the fungi) appear in the dead spots.
- Blotches grow in size until the entire leaf is brown.
- The leaf falls off the plant.
- Partial or complete premature defoliation
- Reduced growth
- Increased susceptibility to pests and other diseases


- Dissolve ½ teaspoon of baking soda and one teaspoon of liquid soap in a gallon of water. Using a spray bottle, spray on tops and bottoms of leaves until the mixture drips off. Repeat every two weeks until existing spots stop enlarging and new spots no longer appear.
- Spray a copper-based fungicidal soap on the leaves, coating the top and bottom leaf surfaces. Reapply as directed on the product label. Copper penetrates the leaf surface and prevents germination of spores so the fungus cannot spread.
- Apply an all-purpose fungicide to the entire plant, following the label instructions carefully.

- Clear fall leaves from the ground before winter to minimize places where fungi and bacteria can overwinter.
- Maintain good air movement between plants through proper plant spacing.
- Increase air circulation through the center of plants through pruning.
- Thoroughly clean all pruning tools after working with diseased plants.
- Never dispose of disease plant material in a compost pile.
- Avoid overhead watering to keep moisture off of the foliage.
- Keep plants healthy by providing adequate sunlight, water, and fertilizer.







- Apply insecticide. For an organic solution, spray plants with a Bacillus thuringiensis (Bt), which specifically affects the larval stage of moths and butterflies. Be sure to coat plants, since caterpillars need to ingest Bt for it to be effective. This will not harm other insects.
- Spray a chili extract. Chili seeds can be cooked in water to make a spicy spray that caterpillars don't like. Spray this mixture on the plants, but be aware it will also be spicy to humans.
- Introduce beneficial insects. Release beneficial insects to the garden that eat caterpillars, such as parasitic wasps.
- Hand pick. Using gloves, pick off caterpillars on plants and dispose of them in a bucket of soapy water.
- Dust plants with diatomaceous earth. This powder is harmless to humans but irritates caterpillars. Therefore, it will make it difficult for caterpillars to move and eat.

- Monitor plants. Check plants regularly for caterpillar eggs on leaves. If they do not belong to an endangered species, they should be squished.
- Use insect netting. Cover plants with insect netting to prevent butterflies and moths from laying eggs on plants.
- Apply diatomaceous earth. Apply DE to plants early in the season and reapply after rain.
- Encourage plant diversity. This will attract predatory insects including parasitic wasps.






- Protect the trunk and leaves from physical damage like scrapes.
- If pests or disease are the cause of scarring, isolate the plant from others to avoid further spread. Some pests can be removed with organic remedies such as a soft cloth and soapy water solution or diluted isopropyl alcohol spray.
- Stop sunburn by moving your plant away from direct sunlight and making sure it has the water it needs.
- Frequent leaf or bud loss may be due to insufficient light or nutrients.

- Review specific guidelines for your plant, including soil drainage, watering, and fertilizer requirements.
- Inspect plants before planting and use sterile pots and fresh potting soil or media to limit transfer of fungi or bacteria.
- Once established, check your plants regularly for signs of scarring or the presence of pests, as it is better to catch problems as early as possible.






- Leaf galls appear on most herbaceous plants and trees. They are more prone to develop on new growth and following mild winters in which insects and diseases were not killed by the cold.
- Leaf galls look like leaf curls, nipples, blisters, or erineums (hairy growths) and can occur on upper or lower leaf surfaces.
- Bud or flower galls cause these parts to be deformed in size or shape.
- Stem and twig galls cause deformed growth on twigs and stems, with symptom severity ranging from slight swelling to large, knot-like growth.
- Stunted plant growth is possible, as galls steal nutrients from the plant.
- Long-lasting damage can occur if there are many galls or galls present for a long period of time.

- Feeding or egg-laying mites and insects - the saliva and other secretions cause the plants to produce more growth hormones.
- High hormone production resulting in increased cell numbers or cell size (because of this, mature plants tend not to be affected).
- Fungal infection
- Galls forming on leaf blades and sheaths are more often caused by viruses or bacteria.
- Nematodes can also cause galls to form on plants, but these tend to form in the roots.
- Parasitic plants such as mistletoe can cause galls on their hosts.

- To treat pests naturally apply an insecticidal soap. Dilute 1 tablespoon of soap per quart of water in a spray bottle and mix gently. Spray the entire plant until the leaves are dripping, making sure to coat the underside and tops. Re-spray every 2 to 3 days.
- To treat organically apply neem oil, a naturally occurring pesticide, per label directions every 7 days until pests are eradicated.
- To treat chemically apply an insecticidal foliar spray. Follow the dosing instructions provided by the manufacturer on the product label.
- For fungal or bacterial causes, apply a bactericide or copper-based fungicide in the spring, following the dosing instructions provided on the product label.

- Rake up all fallen leaves at the end of the growing season, and dispose of the leaves and all other plant debris to get rid of sites where gall producers can overwinter.
- Avoid over-fertilizing plants, as it induces stress, making them more susceptible to pest problems.
- Keep plants well-watered, preventing drought stress.
- Apply dormant oil in early spring to control leaf-eating insects.








- Use a water-soluble fertilizer. Fertilizers will include most or all of the macro and micro-nutrients the plants need to thrive. Adding some fertilizer to the soil will make those nutrients available and can combat deficiencies.
- Regularly apply organic fertilizer pellets. Organic fertilizers such as animal manures and bonemeal can supply plants with all the nutrients that they need to grow strong and healthy.
- Apply compost. Though not as finely tuned as artificial fertilizer, compost can nevertheless be rich in important nutrients and should be applied to the soil regularly.
- Apply nutrients via foliar application. In addition to supplementing the soil with nutrients, foliar fertilizer can be applied directly to the plant's leaves. Nutrients offered via foliar application are often taken up even quicker than those put in the soil, so the foliar application can be great for swiftly addressing specific deficiencies.

- Regular fertilizing. Regular addition of fertilizer to the soil is one of the simplest and most effective ways to prevent deficiencies.
- Proper watering. Both over and under watering can adversely impact a plant's roots, which in turn makes it harder for them to properly take up nutrients.
- Testing the soil's pH. A soil's acidity or alkalinity will impact the degree to which certain nutrients are available to be taken up by plants. Knowing the soil's pH means it can be amended to suit the needs of the individual plants.

1. Choose the right type of artificial light: LED lights are a popular choice for indoor plant lighting because they can be customized to provide the specific wavelengths of light that your plants need.
Full sun plants need 30-50W/sq ft of artificial light, partial sun plants need 20-30W/sq ft, and full shade plants need 10-20W/sq ft.
2. Determine the appropriate distance: Place the light source 12-36 inches above the plant to mimic natural sunlight.
3. Determine the duration: Mimic the length of natural daylight hours for your plant species. most plants need 8-12 hours of light per day.
