Full Moon and cauliflower?

It is not surprising that some people don’t take moon planting seriously when TV commercials make statements like “the increased light of the Full Moon has hastened maturation of cauliflowers”.
All vegetables are exposed to light from Full Moons. Maturity times for different varieties of cauliflower vary from 11- 26 weeks, so the slower growing ones would be exposed to more Full Moons than the faster-growing varieties. In fact, radishes, which are sown after the Full Moon, can mature in a month, and would be exposed to the least amount of Full Moon light.
I thought the statement may have been based on the Moon being in Perigee (closest part of its orbit to Earth) and the reflected light from the Full Moon being slightly stronger. However, the only time the Full Moon was near perigee this year was back in January. Cauliflowers require cold weather to form the curd, and the coldest weather normally occurs when the days are shortest and the plants are exposed to less sunlight. It is more likely that the cooler temperatures this year have assisted the early maturation of cauliflowers, and that TV ad doesn’t make a whole lot of sense to me.

The cabbage family

This family, called the Brassicas, tend to be more susceptible to attack from the Cabbage Moth and the Cabbage White Butterfly when conditions are too warm for them or when the soil they are growing in is too acid for their liking, especially while the plants are young.
The cabbage family includes Brussels sprouts, Chinese cabbage, cauliflower, horseradish, kale, kohlrabi, mizuna, mustard greens, swede, tatsoi, turnip, watercress and stock, and is also related to radish. These plants need both boron and molybdenum for healthy growth and these are only available to plants when the soil pH is close to neutral. If you know that your soil is acid, and your Brassica plants are being attacked, give the bed a drink of dolomite or agricultural lime. Dissolve a generous handful in a full watering can and apply this to each square metre of the bed. Repeat the application if pests are still hanging around in two weeks.
In the meantime, remove all pest eggs from under leaves and leave crushed caterpillars on the leaves. This helps to deter further egg laying.
