In zone 7b (NY) lettuce seeds can be planted outdoors Jan-March ? I know that's what the chart says, but just confirming! I always thought March was the earliest. Are there specific varieties that are best that time of year? TY!!

Could you give me a few lettuce varieties that grow well in MN? I got a good crop of Arugula but would like some sweeter varieties. Thanks

Agriculture: Molybdenum deficiency is often only revealed in LOW YIELDS. Mo deficiency is the most widespread deficiency after Zinc & Boron. Excess molybdenum in pastures can give rise to animal health problems (in reality it is the nitrogen - Mo acts as bottle neck, so that plants can't uptake a lot of nitrogen -- in high Mo soils nitrogen uptake can be too high-- Ireland -- maybe investigate Denitrifying bacteria, microorganisms whose action results in the conversion of nitrates in soil to free atmospheric nitrogen - also useable in areas where nitrogen is washing into the lakes, rivers and streams). ********** Sometimes Molybdenum (Mo) deficiency can appear like a nitrogen deficiency ************** - it makes sense since Molybdenum (Mo) is required for plant assimilation of nitrogen (both atmosphere and soil). So you might be applying lots of nitrogen.... in situations where you have a molybdenum deficiency.... then just washing away your nitrogen into local rivers, lakes and streams.************* this will cause health problems in aquatic life ******************* Molybdenum is present in the lithosphere at average levels up to 2·3 mg kg−1 but can increase in concentration (300 mg kg−1) in shales that contain significant organic matter. The sources of high-molybdenum soils are Carboniferous black shales and limestones. Don't worry so much about the numbers - it's enough to know that Carboniferous black shales may contain 150 times more Mo than average (in the lithosphere). Molybdenum was the most abundant trace element present in the soluble and insoluble extractions of the wood-ash. ** also see banana peel compost which are high in molybdenum (Mo). *** Take away -- nitrogen is usually not the problem when you see symptoms of nitrogen deficiency -- it is more likely a Molybdenum deficiency.

To increase the levels of Molybdenum (Mo, also called Molly) in your soils -- wood ash (from a fireplace, firepit, or barbeque) can be incorporated into the soil. Alternatively, Banana peels are an excellent source of Moly. Animal manure tends to (grass/grain/vegetable feeders) tend to have a decent amount of Moly in their manure. If all of these are out of reach, perhaps try incorporating wood chips/bark mulch in your garden. You can make bark chip paths, use the paths, then the following year when the chips are broken down mix them into the soil. OR -- just mix the wood chips (bark, mulch, whatever) directly into the soil. As the wood is breaking down it takes a lot of nitrogen. I would expect to find Moly in leaf mulch - but have not found any reliable sources that have stated this as a fact. If you choose to use chemical forms of Moly remember that this is a TRACE element - VERY little is needed and over application can result in a OTHER problems. Staying organic almost guarantees you will not over apply. If you live in an area where wood burning stoves and fireplaces where common for heating (pre- electric fireplaces and stoves) - and you know people old enough to have been around when wood ash was common in the garden (there was no place else to put it) - they can tell you how amazing the gardens where back then.

How much sun/shade does lettuce require? Would love to plant in a mostly shaded area of the outside.

MOSTLY Shade greens (which is a couple of hours of sun per day): Asian greens (bok choi, pak choi, komatsuna, tatsoi), misuna, kale. mustard greens, arugula AND yes, lettuce... but when you say mostly shade.... and I start to think of what the conditions are like after watering.... wet shade.... and for my zone this means slugs and slugs love lettuce; and for that reason I would probably go with a green other than lettuce -- looking in particular for a firmer, stronger tasting (hotter) green. SOME SEEDS need light to germinate... so you need to start these plants elsewhere and transplant, or perhaps chose a green whose seeds do not need light to germinate.

Most crops need plenty of sun otherwise they grow small and weak. There are different varieties to plant in summer or winter.
