Soil Preparation
Soil Preference:
Soil pH: 6.1-7.8, Ideal 6.5-7.5. Many gardeners prefer growing Nasturtiums in nitrogen poor soil, as nitrogen rich soil encourages more vegetative growth with less blooms. Grow in well drained soil. In gardens with very sandy soils, add compost to help retain moisture.
Soil Preparation:
Compost (Nitrogen), 2", in top 6" of soil, 1 time: In gardens with very sandy soils, add compost to help retain moisture. Otherwise omit.

Start Indoors
Seed Sowing Depth: 0.25" to 0.5". Plant nasturtiums seeds 1/2" deep for best results. Some gardeners soak the seeds in warm water overnight for higher germination rates.
Soil temp for germination: 55°F to 70°F, optimal 60°F to 65°F, optimal 65°F
Total weeks to grow transplant: 5 to 7 (Spring/Summer), 5 to 7 (Fall/Winter)
Germinate:
1-2 weeks before last frost date: For Spring planting, it is a good idea to put your seed in the freezer for a day or two, then thaw for a day. If you freeze them just before planting, you will significantly improve the germination rate of the seed. Soaking your seeds before planting also helps.
Sow 2 seeds each in individual 4" pots of well-drained seed starting mix 3 weeks before the last expected frost date. Cover 1" deep. Provide a strong light source. When seedlings have several sets of leaves pinch out the weaker seedling leaving 1 per pot.
Harden Off:
1 weeks after last frost date. When weather is evenly in the 50˚ F range harden off by leaving the plants outside for longer periods of time each day.

Sow seeds in spring once all danger of frost is over in full sun (or part shade in hot climates). Nasturtiums need no added fertilizer in most soils. Poke seeds into well-worked soil about 1" deep and 3 to 4" apart (thinning later to the recommended spacing, keeping only the healthiest and most productive plants). Press soil firmly over the seeds and keep moist.

The whole plant is antibiotic, antiseptic, aperient, diuretic and expectorant. It is useful in breaking up congestion in the respiratory passages and chest during colds. The juice or tea can be used as an external or internal antiseptic. The plant has antibiotic properties towards aerobic spore forming bacteria, it is also said to have a beneficial effect on the blood by promoting the formation of blood cells.

Allies: Nasturtiums are said to deter pests-including white flies-from beans, cabbage and its relatives, and cucumbers. Some companion gardeners plant nasturtiums where they will later plant their squash, hoping to keep squash bugs away. Scientific trails show conflicting evidence. In some tests, pests are reduced; in others, the nasturtiums had no effect, or worse, appeared to draw pests to the garden. It's worth conducting your own field trials. The growing plant attracts aphids away from other plants. Research indicates that aphids flying over plants with orange or yellow flowers do not stop, nor do they prey on plants growing next to or above the flowers.
Companions: Nasturtiums are available in compact or trailing forms. They flower well in poor soil and tend to produce more leaves than flowers if you plant them in the rich soil of the vegetable garden. Trailing types are pretty in a window box with marigolds and other annuals.
Enemies: None known.

Cabbage: Late Flat Dutch (Heirloom) (Brassica oleracea var. capitata)
$1.00 - $5.60
Late Flat Dutch cabbage can be traced back to 1840, when the earliest mention of this variety is found in the seed records of the Netherlands. German immigrants carried the seed with them to America, where it spread; by 1924, it could be found in local seed catalogs such as D. M. Ferry & Company.
Cabbage: Red Acre (Heirloom) (Brassica oleracea var. capitata)
$1.00 - $5.60
Cabbage is considered one of the oldest cultivated vegetables, since historians trace it back to 4,000 BC in China. The Romans also cultivated it and praised it for its healing qualities; philosophers Pythagoras and Cato both made the lowly cabbage the subject of a book. Jacques Cartier brought the first cabbage to America in 1536. Cabbages were quite popular in colonial America, being pickled and preserved in every possible way to provide food for the winter.
Cabbage, Chinese: Pak Choi (Heirloom) (Brassica rapa var. chinensis)
$1.00 - $5.60
Chinese cabbage dates back to the 15th century in China, when a pharmacologist of the Ming Dynasty considered it nutritionally beneficial. Later it became the main ingredient in kim chi, the national dish of Korea; Japanese soldiers also discovered Chinese cabbage and took it home with them after the war. Americans became familiar with this vegetable in the late 19th century.
Cucumber: Lemon (Heirloom) (Cucumis sativus)
$1.00 - $5.60
Historians generally agree that the first cucumbers grew in India's Himalayan Mountains over 3,000 years ago. From this region they expanded into Greece and Rome; the Romans most likely spread this vegetable to the rest of Europe. The cucumber was widely grown by native Americans through the influence of the Spanish and other explorers. Cucumbers continue to be a vital part of traditional cuisine in Russia and many parts of Asia; the greatest variety of colors and shapes of this vegetable can still be found in its Asian birthplace. Lemon cucumbers in particular can be traced back to the gardens of the 1890s.
