Basil plants are commonly known as mints or spearmint. They are grown all over the world. The plant was introduced into Europe from India in the 16th century. Today they grow wild in many places around the globe, especially in warm climates where it gets too cold to survive otherwise. In North America they have been found growing along streamsides and even near some cities such as New York City and Washington D.C.. In fact, the name “curl” comes from their ability to curl up when wet.
The leaves of basil plants turn yellowish green after they are damaged by insects such as aphids, mealybugs and scale insects. These pests attack the stems and roots of the plant causing them to wilt.
When these damage occurs, it causes the stem and root tips to become discolored or even die completely leaving only a few dead branches at its base.
Yellowing leaves on basil plants are not uncommon. However, there are several ways to treat this problem.
One way is to simply remove the pest infested parts of the plant and replace them with healthy ones. Another method is to cut off any damaged areas of the plant altogether so that new growth will take its place.
When growing basil plants from their seeds, it is important to keep them in small pots until the roots begin to poke through the bottom. This usually takes about one to two weeks after planting.
Once this occurs, each plant can be planted individually into larger containers or directly into the ground. The best time of year for planting would be after the last frost in your growing area.
There are several ways to help your basil plants thrive. One way is to choose a location that is sunny and has well drained soil.
When establishing your plants, it is important to water them immediately after planting. This helps the stems to become stronger and establish a good root system. Established plants can be watered as much as needed or they can even be allowed to go dry. If the leaves begin to wilt, however, they should be watered immediately.
There are several types of basil plants that you can try to grow. The first is commonly known as ‘Sweet Basil’.
This type has a sweet taste and is used in dishes such as tomato sauce and pesto. There is also ‘Lemon Basil’, which is perfect for fish and chicken dishes. Other types include ‘African Blue’, ‘Cinnamon’, ‘Dark Opal’ and ‘Anise’. Another thing to remember when growing basil plants is that they can be grown both indoors and outdoors. If you have an abundance of either, you can dry them and preserve them for later use in meals.
Once you have grown your basil plants, you should harvest them before the flowers begin to form. This is because the leaves lose much of their flavor once this occurs.
Also, when growing basil plants, it is best to prune them. This can be done by cutting off whole stems just below the top set of leaves. This encourages the plant to branch out and grow even more. If you find that your plants are growing too close together, you can also prune them by cutting some of the branches off completely.
While growing basil plants, you should take care not to over water them or the roots will begin to rot. It is best to only water when the top inch or so of soil is dry.
Also, make sure they are getting at least 6 hours of direct sunlight each day. Another way to help your basil plants grow is to add fertilizer to the soil about once every month. It is very important that the fertilizer you choose is specifically for herbs. this will provide the correct amount of nitrogen, which promotes leafy growth.
When harvesting, always cut the stems just above your fingers with a pair of scissors or a knife. Then, put the basil in ice water.
This will keep it from turning brown and provides a clean taste and smell. Make sure you allow it to drain completely before use. Also, be sure to discard any wilted, bruised or contaminated basil immediately as this may cause food poisoning. Other than that, growing basil plants is very easy and anyone can do it with the right amount of sunlight, water and care.
