How do you keep fresh basil from turning black?
To keep basil fresh, trim the stems and place them in a glass or jar of water, just like cut flowers. Loosely cover it with a plastic bag and leave it on the counter. Although certain herbs, such as parsley and cilantro, can be stored this way in the fridge, basil does better at room temperature.
This basil disease is caused by a bacteria called Pseudomonas cichorii. Symptoms of bacterial leaf spot are black or brown spots that appear on the leaves and streaking on the stems of the plant. Bacterial leaf spot occurs when infected soil is splashed onto the leaves of the basil plant.
- Slugs or Snails. Slugs find the basil plant leaves almost as delicious as you do. They create ragged holes in the basil plant leaves after climbing up the plant. While basil plants like mulch to help retain the moisture they enjoy, it is also a conduit for the slugs.
- How to Cultivate Basil
- Soil: Basil does its best in well-drained, moist soil with a neutral pH.
- Sun: Basil grows well in warm environments that receive about six hours of sun each day.
- Water: Give basil water when the soil is dry to the touch, doing your best to water the plant at its base and not all over its leaves.
- Improper watering – Root rot, a result of too much water, is one of the most common reasons for yellow leaves on basil plants. Water basil only when the top 1 to 2 inches of soil is dry, and remember that slightly dry soil is healthier than soggy soil.
Too much water, too little water and lack of sun will turn the basil leaf tips brown and cause them to curl. To keep the leaves from browning and curling, ensure the basil receives enough water without drowning it by allowing the first 1 to 2 inches of the soil to dry before watering.
- Basil propagation from cuttings is quite simple. Change the water every few days until you see root growth, then leave your basil propagation roots to grow to about 2 inches or so. This can take two to four weeks. Once the roots on your basil cutting are 2 inches or longer, you can plant the cutting in a pot indoors.
- Once you're certain you have an infestation of downy mildew, move quickly to save your plants.
- Remove any completely infected plants from the garden.
- Remove all infected leaves from a plant that is not fully infected.
- Thin out the garden bed to increase air circulation.
- Stop overhead watering.
- Apply fungicide.
- Treatment. Leaf curl can be controlled by applying sulfur or copper-based fungicides that are labeled for use on peaches and nectarines. Spray the entire tree after 90% of the leaves have dropped in the fall and again in the early spring, just before the buds open.
The fresher it is, the better it is. The fragrance of basil is never as seductive as when it is first plucked from a live plant and eaten raw, as quickly as possible after plucking. Basil pesto too, should always be used raw, never warmed up or cooked.
- As far as we know, most herbs—your rosemary, thyme, basil and dill—are safe for cats and dogs, but there is one that frequently colors a person's garden that can cause a sometimes severe—and definitely strange— illness. As for fruits and vegetables, tomatoes (particularly the leaves) can be toxic to dogs and cats.
- Stack the leaves: Stack the basil leaves on top of each other. Stack them so the top of the leaf is down and the underside is facing up, so the leaves cup each other. Roll the leaves into a cigar: Gently roll the leaves into a cigar. Hold the roll closed against the cutting board with your fingers curved.
- THE BOTTOM LINE: While we don't recommend using the thicker stems from a bunch of basil, it's perfectly fine to make the most of your basil bunch and put the younger, more tender stems to use. 1. Don't process thick stems in pesto.
