Annuals sowing

The most promising allelopathic weeds are hawkweeds (Hieracium spp.). They are effective in reducing other asteraceous weeds (Murphy and Aarssen 1995b) and yellow hawkweed (H. pratense Tausch.) inhibited Canada thistle (Cirsium arvense (L.) Scop.), perennial sow-thistle (Sonchus arvensis L.), yarrow (Achillea millefolium L.), and annual sow thistle (Sonchus oleraceus L.) however, the long-term effect on perennial species is unclear (Murphy 2001). 

Plants, both hardy and half-hardy, that germinate, flower, set seed, and die within one year, such as marigolds, are known as annuals. Biennials, such as foxgloves, take two years to complete this process. Both can be more labor-intensive than bulbs, perennials, and woody plants, as you have to sow them each year however, this does allow for an annual change of color scheme. 

Many hardy annuals, such as calendula (pot marigold), Phacelia tanacetifolia, and the poached-egg plant Limnanthes douglosii), will self-seed, reappearing year after year. Self-sown plants tend to be much sturdier, and flower earlier, than those you sow yourself. Unwanted seedlings can simply be hoed off, or transplanted to a more appropriate site. 

A tall, pretty flowering annual grown for leaves and seeds (ealled eoriander). Speeial seleetions for leaf produetion are available. Needs a sunny spot, in light but fertile soil. Sow direet from spring to fall for a eontinuous supply of leaves. Goes to seed guiekly in hot weather. 

A biennial grown as an annual for leaves with the best flavor. Quite hardy, but needs winter proteetlon In eold regions. There are both eurly and flatleaved varieties. Parsley enjoys partial shade and moist, fertile soil and Is good In eontalners. Sow In spring and summer for summer harvest, and In late summer for a winter erop grown under eover. 

Many herbs are easy to raise in the garden. Young herb plants are widely available in garden centers, although specialty herb nurseries offer a more varied and interesting selection. Annuals and biennials such as parsley and basil are grown from seed. Some perennials, such as fennel and chives, are also easy to raise from seed, and may self-sow. 

In ICP-AES analysis, the IDLs must be determined every time an instrument has been adjusted in a way that may affect its sensitivity and interelement correction. The CLP SOW requires that the IDLs be determined at a minimum on a quarterly basis. Laboratories that are not part of the CLP determine IDLs annually. Table 4.4 shows... 

Basil is an annual herb grown for its aromatic leaves. To grow healthy, trouble-free plants, sow seed indoors in 70°F soil mix. or outdoors after the soil has warmed. Basil does best in rich, moist, well-drained soil with a pH between 5.0 and 8.0, and needs at least 4... 

Dill is an annual herb grown for its tangy leaves and seeds. Sow seed outdoors where the plants are to grow after the soil is warm. Dill prefers a site in full sun with rich, well-... 

Cultivation Needs warmth for germination, sow seeds 1/4" deep in full sun. Pretty much any soil mix works, these germinate easily within a week or two. Keep moist. Transplant young and keep up with pot sizes as roots crowd, or plant out Best growth is with ample root space and fertile mix. D. stramonium is an annual and will set seed, then die. Likes sun and heat. ... 

The main field of application of dinitroaniline herbicides is the control of annual grass weeds. Some annual dicotyledonous weeds are also sensitive to dinitroaniline herbicides in the initial growth stage. All members of the group are fairly volatile, and are hence sprayed before sowing to the soil surface and immediately incorporated to a soil depth of 6-8 cm. Owing to their poor water solubility, they are not absorbed from dry soil in adequate quantity by the plant, so under dry conditions their action is unsatisfactory. 

Sow sweet peas, cerinthe, and other hardy annuals early because they tolerate the cold. Half-hardy annuals, such as zinnias, cosmos, and antirrhinums, can be sown indoors and planted out once there s no risk of frost. Late-flowering annuals, such as chrysanthemums, can be sown directly in the ground.
