Sunflower 24 Oct, Celeste Arcjer (Canada - Zone 5a Temperate Warm Summer climate)
One last thought -- and whether this is a good idea or not will depend on the "tastes" in your area. (using info from the net): The Jerusalem artichoke (Helianthus tuberosus) is closely related to sunflowers. Specialty producers treat Jerusalem artichokes as a very versatile, gourmet root vegetable under multiple names such as Sunchoke (created and trademarked by Frieda Caplan) and lambchoke, as well as sunroot, wild sunflower, earth apple, earth pear, and topinambour (in France and Germany). They have also been called French potatoes, German turnips, and Canadian artichokes or truffles. They can be sliced and eaten raw (after washing the edible skin) and are variously described as sweet, savory, nutty, and crunchy, similar to water chestnuts, jicama, or milder radishes. They are often boiled, roasted, or mashed, with a flavor very similar to potatoes or artichoke hearts. They can also be fermented or pickled, and ground into flour. Jerusalem artichokes look similar to ginger root or turmeric and potatoes. They can be short or long and brown, white, red, purple, or grey in skin color. Wild tubers are often red and plants are spread across fields; when cultivated, they appear white and clustered together. Tubers are oblong, with lumps or knobs. The inside is white until exposed to air when the flesh will begin to darken. More than 200 varieties of Jerusalem artichokes exist including Clearwater, Columbia, Mammoth, Oregon, Red Fuseau, Stampede, and White Fuseau. Jerusalem artichokes are a hardy perennial able to grow well in most soils. Ideally, the ground is loamy, loosely packed, and with a slightly alkaline pH value of around 7. Temperatures between 65 to 80°F (16c - 26 c) are preferred for optimal growth, along with 125 or more frost-free days. More sunlight is needed for the initial growing stages, then less is preferable as the tubers form. Precipitation will aid in growth, especially during sprouting, but too much moisture will waterlog plants. In commercial production, Jerusalem artichokes are raised annually, despite their perennial nature. Growth takes 7 months on average, seeds are often planted in early spring for best yields. ...................... certainly worth thinking about. Sunflowers for oil production probably have more "certainty" when it comes to demand. Sun chokes may not have the demand (initially - or maybe ever) in your area to support a farm dedicated to Sun chokes and Sun Chokes are know for their "delicate" skin which may make shipping tricky (avoiding spoilage)..

I found this publication, which might be a good starting point for you: https://www.tandfonline.com/doi/full/10.1080/02571862.2024.2352174#d1e710 ----- the Abstract starts ---------- Abstract Suitable planting dates and hybrid selection are crucial in optimizing yield, component traits and oil production in sunflower (Helianthus annuus L.). In South Africa, there is limited information on the effects of planting dates on currently available sunflower hybrids in the marketplace.....

You would probably have more help from a local agricultural advisor. Gardenate is intended for home gardeners, not farmers.

Sweet corn (also corn,maize) 20 Oct, K-M Bourke (Australia - sub-tropical climate)
I never have much success growing from seed but I really want to level up my gardening. How much sun do I allow my seedling trays to get. In a sub-tropical climate the sun can be very intense on hot days and can dry them out very quickly. Should I use a greenhouse or is that too shady? How often should you water them? I assume the trays should be moist the whole time while they are germinating? Any advice would be appreciated.

Soak the seeds over night in a bowl/glass of water. Plant them into a fine potting mix soil. Give them a watering.. Don't water for 2-3 days. Keep in the shade or only a little sun each day. If soil drying out use a spray bottle to moisten the top of the soil. Or do similarly into the garden. Put some shade over them. Don't over water - they will rot. I have had trouble myself the last few years. Or just buy punnet from Bunnings/? - a lot simpler and easier.

Hi. It is not advisable to grow brassicas in summer as they are cool weather plants. That said, there are certain varieties that have been developed to withstand hotter weather. So, when buying seed, look for those.

Some people eat the young leaves. I think they're reasonably safe in small quantities. I grow it for the flowers and let chickens enjoy the leaves.
