Reasons Pepper Leaves are Turning Brown Browning pepper leaves may be the result of environmental conditions such as frost damage/chilling injury. Usually, this type of injury will encompass the entire plant. That is, not only the leaves, but the entire plant may become discolored and wilted. Also, the inside of any fruit will become brown as well. If leaves are turning brown on your pepper plants, it may also be because you forgot to water them....

Types of Worms on Peppers There is a pepper caterpillar called the tobacco hornworm. This particular pepper caterpillar is green and has a red anal horn.

Pepper grubs eat at the roots of the pepper plant and prevent the plant from absorbing the nutrients it needs from the soil....

What is Phenology? Everything in nature is the result of phenology. Granted, human involvement and natural disasters can alter the natural order of phenology but, generally speaking, organisms, including human beings, rely on and act according to the predictable nature of seasonal changes. Modern phenology began in 1736 with the observations of English naturalist Rober Marsham. His records of the connections between natural and seasonal occurrences began that year and spanned another 60 years....

When to Pick Leaf Lettuce Lettuce is a cool-weather crop and, although it needs sun, is one of the few crops that will do well in partial shade.

Loose-leaf lettuce harvest can begin anytime the leaves have formed but prior to the formation of a seed stalk....

But ‘Pink Lemonade’ is staging a come back as gardeners increasingly want blueberries for their cancer-fighting antioxidants....

Plant Propagation Calendar A plant propagation calendar itemizes what plants can be propagated each month. Some seasons are more conducive to softwood or hardwood cuttings, layering, or saving seeds. Fall plant propagation is generally done by softwood or hardwood cuttings.

Planting Flowers in Fall In planning a flower garden, possible choices can greatly be impacted by weather. Knowing the difference between cool season and warm season blooms will be essential to success.

This method is especially effective for those planting native wildflowers....

Information on Pokeweed in Gardens First of all, most people don’t actually cultivate pokeweed in their gardens.

Learning how to grow tuberose in the home garden is simple, however, care of tuberose flowers after bloom requires effort, proper timing, and storage of the tuberose bulbs (actually rhizomes), which must be dug up before winter in some areas....

Studies show the addition of pollinator friendly plants to your landscape can increase vegetable and/or fruit yields. Some good pollinator plants for vegetable gardens include echinacea, rudbeckia, monarda, and butterfly bushes. Pollinator-Friendly Companion Plants for Vegetables Crop plants pollinate by insects or wind. If the plant produces separate male and female flowers, a bee carries pollen from the male flower to the receptive female flower. If the male and female structures are located within each flower, visiting insects will help to move or shake the pollen loose....

Reasons a Pomegranate Tree is Losing Leaves Do pomegranate trees lose leaves? Yes. If your pomegranate tree is losing leaves, it could be due to natural, non-damaging causes such as deciduous annual leaf drop.
