Issue 49 Life Cycles of Annual and Perennial Weeds
Annuals - In one season, a seed (A) sprouts. The seedling (B) grows to maturity and flowers (C). After it flowers, the seeds ripen (D) and the plant dies.
Seed Life Cycle: Germination
Depending on the type of seed, it may or may not require soil or light to germinate. However, most all plants need water in order for this process to occur.

The Japanese Beetle Life Cycle
By: Gene Rodriguez, III
Japanese Beetles (Popillia japonica Newman) are a non-native invasive pest that is found in every state east of the Mississippi River.
Life Cycle:
Moths emerge from overwintering pupae in late spring (late April to May) and lay clusters of up to 500 greenish eggs on leaf surfaces of host trees.
LIFE CYCLE OVERVIEW
Midges (adults) produce from one to three generations per year. The actual number of generations produced in a given year depends upon weather conditions and the location of the vineyard.
Life Cycle
Wisconsin is home to many slug species, the most damaging are the gray and spotted garden slugs. In Wisconsin, slug adults and eggs overwinter, and then become active during the warm days of early spring.
Life Cycle of the Japanese Beetle
The first beetles to emerge start to look for suitable plants to eat and start feeding immediately. They also send out an odor known as a congregation pheromone to signal later emerging beetles where to go.
Life Cycle
Adults lay egg masses in moist soil, or under rocks or containers, or garden debris. Eggs hatch in 2 to 4 weeks. Slugs grow for 5 months up to 2 years before reaching maturity; snails take 2 years to reach maturity.
Snail: ...
Life Cycle
The adults lay eggs in soft organic matter on the ground under the host plant where the larvae burrow through the soil feeding on the roots of the host plant and pupate in the soil.
The Life Cycle
The adult Cicada is a flying insect. Different "broods" emerge in periodic cycles. The life cycle of a particular brood lasts from 2 to 17 years.
Their life cycle
The adults overwinter in leaf litter, emerge in late spring and feed on the leaves. They lay eggs on the crowns of plants. The larvae feed on roots.
Plants they attack
Strawberries, raspberries, tree fruit, and ornamentals.
Life Cycles and Habits
The hairy chinch bug adults overwinter in the thatch and bases of grass stems in the turf. However, the common chinch bug prefers to move to tall bunch-grasses in open fields to find overwintering sites.
Life Cycle
The has an unusual life history. Eggs are laid by the moths in late summer and early fall. Most eggs are laid in weedy areas of wheat fields, alfalfa fields or other areas where vegetation is thick.
Life cycle of a bulb
When first planted, a bulb is in its dormant period. It quickly anchors its roots into the soil and then starts to produce the first small stems which will become the leaves and flowers.

The life cycle of beneficial nematodes consists of six distinct stages: an egg stage, four juvenile stages, and the adult stage. The adult spends its life inside the host insect.
The life cycle of a gymnosperm is clearly represented by the white pine, Pinus strobus. Every spring, pollen-bearing male cones appear at the ends of the tree's lower branches, clustered just below the new crop of needles.
Having a life cycle in which chromosome segregation and recombination does not take place.

A: This is a good description of hollyhock rust, a disease that can complete its life cycle on one host plant. Sanitation is the first tactic. Remove leaves as soon as pustules appear on the under side. Destroy all foliage and stalks in the autumn.
Foxgloves are biennials, meaning they complete their life cycle over two years. The best way to get them established is to buy small transplants and put them in the ground in early fall.
Whitefly are difficult to control because they reproduce so quickly (average life cycle is 30-34 days) and frequently build up a resistance to pesticides; therefore you need to be vigilant when it comes to treatment.
There are four stages to a butterfly's life cycle: egg, larva, chrysalis (pupa), and adult. All stages of the life cycle require specific plants to ensure the attraction of butterflies. An adult butterfly lays its eggs on a host plant.
Butterflies have a life cycle
Butterflies have two feeding stages: the caterpillar and the mature stage.
Most pests have a very short life cycle and don't actually do that much harm.
Deal with the worst offenders. Handpick and destroy the problem insects or carefully apply an organic pesticide that specifically targets the problem pest.
Annual plants complete their entire life cycle, from seed to flower and back to seed again, all in one season. Because their time is limited, annuals bloom with gusto, often for months on end.
All bulbous plants have similar life cycles. They go through periods of growth and flowering, followed by a dormancy period. Some are spring growers, while others grow in the summer or fall. Bulbs are usually sold in their dormant, dry state.
Waiting for Wings is a brightly illustrated book that follows a butterfly's life cycle from egg to beautiful winged insect. It talks about how butterflies eat nectar and then lay eggs to start the cycle again.
A plant that completes its life cycle over the course of two growing seasons. The life cycle begins with germination in the spring or summer of the first season, during which stem and leaf growth occurs.
You will need to know the life cycles of certain pests and which ones are likely to destroy your plants. Organic gardeners usually allow for a certain amount of damage resulting from pests. Some pests do their damage for a short time, then move on.
Your basil is probably coming to the end of its life cycle.Basil is a tender annual and as such does not grow beyond one season. It will flower, seed and die and if you are lucky the seeds will fall and germinate in the spring.
So when you are planning your garden, keep in mind this life cycle of the plants you choose to add to your garden design.
This factor, combined with a short life cycle, allows populations of aphids to build quickly.
Look-alikes: Spider mite damage; herbicidal damage; environmental stress.
Plants attacked: Virtually all plants.
Definition: A biennial is a plant that completes its life cycle in two years. In a biennial's first year, it will start as a seed and grow roots, stems, and leaves. It will go dormant (die back) over the winter.
Deadheading will trick your flowers into believing the life cycle is not over, encouraging them to continue blooming. When you see your flowers losing color, this is your first indication that it's time to deadhead.
Annuals are plants that complete their whole life cycle in one growing season. In other words, they sprout, grow to maturity, bloom, drop seeds, and die in one season. The next season, the seeds sprout and begin the cycle again.
Biennial-a plant with a two-year life cycle that typically produces flowers and fruits in the second year of life.
Biennial- A plant whose life cycle extends over two growing seasons. The first year the seed germinates and produces a seedling that usually remains short of the winter.
Plants called biennnials complete their life cycle in 2 years. Two familiar biennials are Foxglove (Digitalis) and Canterbury Bells (Campanula medium.) Typically, you plant seeds in spring or set out seedling plants in summer or fall.
Considering their four-stage life cycle and the fact that one flea can produce a trillion offspring in less than a year, getting rid of a flea infestation can be quite a challenge! Read on to find out how.
