Broccoli that matures during cool weather produces healthy heads that taste sweeter than those you pick at any other time.Broccoli grows best in full sun and where the soil is slightly acidic — with the pH between 6.0 and 6.8 — fertile, and well-drained, yet consistently moist and rich in organic matter.A boron deficiency can cause broccoli to develop hollow stems, but adding too much is toxic to plants, so a soil test is essential.Broccoli is a moderately heavy feeder, so work in 2 to 4 inches of rich compost or a thin layer of well-aged manure before planting.After you've harvested a plant's central head, you can encourage extended side-shoot production by scratching a little nitrogen-rich fertilizer such as fish meal or aged manure into the soil around its base."I've had broccoli freeze solid, and when it thawed out it was fine," says Atina Diffley, co-owner of Gardens of Eagan Organic Farm in Minnesota.Offer cold-weather protection with floating row covers, which provide an additional 4 to 8 degrees worth of warmth — shielding harvests from heavy freezes and extending the season by up to four weeks.But if your broccoli does suffer an infestation of destructive caterpillar pests such as cabbage loopers, you can control them with Bacillus thuringiensis var. .

Which Vegetables Prefer Acidic Soil?

Depending upon each type's individual needs, the acidity or pH level determines what nutrients are available to plants and how efficiently they are absorbed.Vegetable plants that do best in mildly acidic soil include carrots, cauliflower, celery, cucumbers, garlic, sweet peppers, pumpkins, winter squash and tomatoes.For example, SUNY College of Environmental Science and Forestry says sweet peas, kale, lettuce, pole beans, cole crops such as cabbage, Brussels sprouts and broccoli, asparagus and radishes require a pH closer to neutral, while potatoes grow best in soil that is significantly more acidic, gauged as low as 5.1 to a maximum of 6.0.Many minerals and nutrients must be dissolved in the soil before they can be easily absorbed along the narrow pathways that run through the roots and main stems of most vegetable plants. .

Soil pH for Organic Gardeners

A few years ago, our mature blueberry bushes seemed to lose their stiffness, producing arching limbs that should have been straight.This problem gave me a reason to get out my soil testing stuff, which makes me feel like a sixth grader with a new chemistry set.Most garden suppliers sell inexpensive pH test kits or digital meters, which are super simple to use.There are exceptions, with potatoes and most berries growing best in acidic soil, and asparagus and cabbage family crops happiest in near-neutral conditions.pH 5.5 - 6.5 Bean, Brussels sprouts, carrot, chive, collard, corn, cucumber, garlic, kale, kohlrabi, mustard, parsley, pea, pepper, pumpkin, radish, rutabaga, squash, sunflower, tomato, turnip, watermelon Apple, apricot, cherry, currant, gooseberry, peach, pear, strawberry Neutral to alkaline.My blueberries did have an elevated pH problem, which probably developed when veggie beds higher on the slope were dusted with wood ashes, which has a liming effect on soil. .

Vegetable Crop Soil pH Tolerances

Vegetables and other plants grow best when the soil pH is optimal for the plants being grown.It is important to match a plant to the soil pH or to adjust the soil pH to a plant’s needs.Soil pH is the measure of the soil’s acidity or alkalinity.Soil acidity and alkalinity is measured on a scale of 0 to 14, called the pH scale.Most plants grow between the pH range of 4.5 to 8.0; a soil pH of 5.0 has a high acid content; a soil pH of 7.5 has a high alkaline content; a soil pH of 7.0 is neutral.A soil pH test will determine a soil’s pH.Soil pH is important because a soil’s acidity or alkalinity determines what plant nutrients are available to plant roots.Nutrients in the soil—elements such as nitrogen, phosphorus, and potassium—become available to plants when they dissolve in water or soil moisture.Most plant nutrients will not dissolve when the soil is either too acidic or too alkaline.Knowing the soil pH in the planting beds in your garden will allow you to group plants by their pH needs.Grow together plants with like pH needs, similar temperature tolerances, and nutritional needs.Crops Listed by Soil pH Requirements:.This list will allow you to group plants according to their soil pH tolerances.You will find that in the lists below, some plants may be repeated if they have a wide soil pH range tolerance; that is some plants will grow equally well in acid or alkaline soil.Acid Soil Crops: The following crops prefer a pH of 4 to 5.5:.Somewhat Acid Soil Crops: The following crops prefer require a somewhat acid soil; they can tolerate a pH of 5.5 to 6.5:.Moderately Alkaline Soil Plants: The following crops will tolerate a pH of 6.0 to 7.0 or greater:.Bean, pole (6.0-7.5).Very Acid to Alkaline Soil Tolerant Plants: The following crops have the greatest tolerance for a wide range of soil acidity or alkalinity, from about 5.0 to 7.0:.Click on These Related Articles on Soil pH:.Understanding Soil pH.How to Test Your Soil.Adjusting Soil pH.Click Here to Get Daily Growing Updates at Harvest to Table on Twitter. .

Growing Broccoli: Planting, Growing, and Harvesting Broccoli Plants

Once you harvest the main head of a broccoli plant, it will often keep producing smaller side shoots that can be enjoyed for months to come. .

Are Coffee Grounds Good for Broccoli? Homemade Fertilizer Guide

And unlike other kinds of kitchen waste, you can easily add coffee grounds directly into your soil without composting or worrying about attracting animals.Used coffee grounds are a gentle fertilizer so it’s not easy to overfertilize and burn your broccoli plants.Used coffee grounds are not a strong fertilizer, but for a single-ingredient soil amendment, they’re packed with nutrients for your broccoli.Most of the nitrogen is instantly available to your broccoli, while the rest will be released over time as soil life decomposes the coffee.Coffee also has important plant micronutrients such as iron, calcium, magnesium, and chromium.Make sure you mix it with the soil, as a thick layer of dried coffee grounds will repel water.Estimates vary, but you can expect an NPK value of approximately 2.1-0.3-0.3, which puts it in line with a lot of commercial single-ingredient organic fertilizers like alfalfa meal. .

Optimum Soil pH Levels for Plants

While these are also crucial things to consider, the pH of the soil plays a major role in how well your plants can absorb the nutrients you provide them, so it’s important to get it right!Hydrangeas, for example, produce different colored flowers depending on whether they’re grown in acidic or alkaline soil.A pH of 6.5 is just about right for most home gardens, since most plants thrive in the 6.0 to 7.0 (slightly acidic to neutral) range.Acidic (“sour”) soil is counteracted by applying finely ground limestone or wood ash, and alkaline (“sweet”) soil is typically treated with gypsum (calcium sulfate), ground sulfur, or compost. .

Companion Planting For Broccoli • Insteading

Companion plants offer shade or shelter, conserve moisture, control weeds, enrich flavor, or provide some form of disease or insect protection.Other garden favorites that grow well planted alongside broccoli are beets, bush beans, dill, lettuce, spinach, rhubarb, cucumbers, Swiss chard, and radishes.Unless continually supplemented with well-aged herbivore manures (e.g. sheep, goat, cow, or horse), few soils contain enough essential nutrients to grow broccoli alongside other members of the Brassica plant family.Broccoli fails to flourish when planted near members of the nightshade family, like tomatoes, hot peppers, and eggplant.Because broccoli is such a heavy feeder, growth and flavor are enhanced when soil is supplemented with a generous amount of nitrogen-rich manure, cottonseed meal, or garden compost.Before planting broccoli seedling, break up the soil to a depth of at least one foot, removing rocks, roots, weeds, and debris.Available in a diverse array of colors including white, green and purple, broccoli is easy to grow with minimal attention.My favorite broccoli varieties include Arcadia, Captain, Di Cicco, Emerald Pride, Everest, Gypsy, Packman, and Windsor.If the seed is sown outdoors, broccoli can germinate in cool soil temperatures of 40 degrees Fahrenheit or above.For spring planting, experience gardeners suggest seeding or setting transplants three weeks before the last frost date.Mulch broccoli plants with a four inch layer of straw or dried grass clippings or ground leaves to conserve moisture.Apply approximately one pound of blood meal when seedlings are 8-10 inches tall and again every 3-4 weeks as the growing season progresses.When tiny flower heads are beginning to form at the center of the plant, watch the growth daily.If allowed to develop yellow flower petals, the buds swell and have a mealy texture and diminished flavor.To reap a second harvest, allow the plant to continue to grow after the first cutting of the main flower head.Many gardeners report the second harvest of small immature flower heads is sweeter and florets more tender than the first cutting.When ready to use, wash broccoli in warm water in a large bowl to which you have added a quarter cup of white vinegar.Soak for 10-15 minutes to remove soil and debris and to kill any insect pests that may be hidden in the tightly packed florets. .
