It's amazing how fast the sprouts germinate. What variety did you plant? I started my Catskill's mid March. After transplanting into 6 packs they went outside. They survived 5 inches of snow on top of the tray a week ago. Won't plant them for another 2 weeks as the plants are only 2 inches tall and I still need the garden tilled. It's about dry enough.
A question for you Ken. My asparagus is coming up. DO I start watering it, even though it's not super dry?
I did find the corn gluten at my seed and feed store.

I have two kinds of sprouts. Last night, some of the pots had more than 2 plants, so I pulled up the smaller ones. They are now at almost 3 inches tall today! Some pots had none showing yet, so I carefully lifted a few from the pots that had more than one, and replanted these in the other empty pots. I also do this with peppers and tomatoes. The two types I planted were Long Island improved and Bubbles. When these get transplanted into the garden, I will be putting down some heavy brown paper mulch to block weeds. The stuff is biodegradable and will remain until they are picked in fall once we get a couple of frosts. Usually I put down a woven black plastic fabric, which has lasted me 4 years now. The black plastic is one of the best weed blockers I have ever used and so I bought a 6 foot wide 300 foot long roll of it. I'm not planting many tomatoes or peppers this year, but instead, watermelons, and cantaloupe, started indoors, and corn directly planted at the end of May. My dill has also been showing up right now. Its from fallen seeds from last summer, and is everywhere along the edges of my garden, as well as between the concrete walk and patio, and in my saffron crocus patch. I also need to plant my fig tree outside as its starting to leaf out already, and has outgrown its very heavy 2 foot square pot. It was always stored in my garage for the winters, but this year it needs a better chance outside. Its a brown turkey variety, and has 5 new shoots emerging from the soil.

The 'gus if it was planted last year, should be fine, but if you add any high nitrogen fertilizer it would be good to water it in. Corn gluten will convert to nitrogen but that takes a few months, so by then the 'gus has passed it harvesting time. I am closly watching the few purple spears I have, and they are still slow in growing. Usually when the 'gus is in its peak, I harvest every two days. I added some fish meal to my 'gus patch after putting down the corn gluten. You can't ever over apply the gluten. Here, we have had very little rain yet (odd for April). I planted some assorted onions and these were watered a few days ago. I also added liquid potash and phosphorous to their watering, and also added some fish meal around the soil as well. My garlic plants are getting huge right now with larger than half inch diameter stalks at a foot tall. They are the Music type hard neck and are huge cloves.

Amazing! I've never heard of such fast germination. Usually I grow whiskers waiting for the seeds to sprout of just about anything.

I do have half a dozen plants in the ground, but I cheated and let the plant farm do the seeding. Jade Cross is about the only good choice this way. Good to have more options with the seed, but I'm lousy at plant starts.

I use heat mats under my plastic trays, and each set of four 11x20 inch trays are under several plant grow lights. My impatiens, and portulaca just sprouted and some petunias, as well as a few of my cantaloupe and watermelon seeds (seedless type). I also found a paper strip with carrot seeds on it. I dug a shallow trench and set the 15 foot long paper strip into the shallow trench and covered it with a little soil. My Asian pear, and peach/plum/apricot trees are swelling buds which should start to open in a few days.

We think that Brussels Sprouts are an amazing vege to grow- we do not eat them- but give alot of ours to a local church that in turn collects items and gives to people that are having a hard time right now.We found that if we give our plants boron we end up with so many brussels sprouts that even the church has too many! Read about the Boron.
Boron is a plant nutrient used in minute quantities by all plants; without it, Brussels sprouts develop hollow stems and small buds,that is why Brussels sprouts need more boron than most other vegetables. If your plants have shown these symptoms, you can add boron to the soil by dissolving 1 level tablespoon of borax ,( you can just go to the grocery store and purchase the 20 Mule Team Brand,) in 5 quarts of water and make sure to sprinke it evenly over your vegetable bed, where the Sprouts are, this will cover 50 feet of bed. It is very important to NOT be tempted to mix more, because too much causes problems. Also, do not apply unless your plants have shown the deficiency symptoms we just mentioned.

I have to use great caution with Boron. I do apply a fruit tree fertilizer about 10 feet from the brussels sprouts. The boron amount in te fruit tree fert is also a trace and helps not only apples to maintain good shape, but also helps strawberry plants from getting deformed berries. I also use it in my red raspberry patch. I just put down regular veggy fertilizer around the sprouts. The plants are still only about 2-3 feet tall and the last time I grew them years ago, I had 5 foot tall plants by this time of year. I used a biodegradable paper mulch to block out weeds. The rest of the garden has black plastic fabric. I plan to allow the sprouts to remain there until a few frosts in late September, and leave the paper mulch there to let it degrade on its own. Mine are ony marble size right now, and are still fighting with loopers and other leaf chewers. The last time I grew them, I had a serious issue with fungus gnats getting into the layers of the sprouts. I don't see many of of those now, and hope they are not going to be a repeat of last time. My fruit tree fert is from Gardens Alive and is the maintenance formula.
