However, growing commercially lavender in today’s competitive landscape requires certain steps towards monitoring, improving and enriching soil nutrients, so that our plants can give high yields for over 15 years.Performing soil analysis once a year is extremely important in order to diagnose nutrient deficiencies and take corrective actions, under the guidance of a licensed agronomist.Lavender plant generally needs more Nitrogen than Phosphorus and Potassium, in order to thrive and give high yields for many years.However, supplying excessive quantities of Nitrogen will have a negative effect in the quality of essential oil, while it will favor the development of weeds.A common fertilizer scheme applied by many conventional farmers involves adding 700 lbs.Organic lavender growers often add 8-10 tons of well-rotted manure per hectare and plow well before they transplant the young plants.They cultivate carefully so that they will not hurt the roots and irrigate well after every manure application, if there are no autumn rainfalls.Your lavender plants may or may not give higher yields in essential oil or floral stems after the application of fertilizers.You can enrich this article by leaving a comment or photo of your lavender farm fertilization techniques and methods.This post is also available in: Español Français Deutsch Nederlands العربية Türkçe 简体中文 Italiano Ελληνικά Português. .

If you are planting the root ball higher than ground level taper your soil mixture gradually from the top edge of the root ball to the ground level, as shown in the illustration above.Spread a 1-inch layer of bark chips or pebbles around the planting area suppress weed growth and conserve moisture.Avoid the use of freshly chipped or shredded wood for mulch until it has cured in a pile for at least 6 months, a year is better.Therefore, I recommend using a quality potting mix that will hold moisture evenly and a container with a drainage hole(s).Not only will you want to pick a color of container that goes well with the flower and foliage color of your Lavender plant, you'll also want to pick a container that matches the style of your home or other structures and other plants in the surrounding environment.Many nursery & garden centers offer a wide variety of containers to choose from.Before filling your container with the soil mix, we recommend lining the bottom with shade cloth or a porous landscape fabric.Apply a 1/2" layer of wood chips, sphagnum moss or pea pebbles to soil surface. .

Fertilizer Calculations for Lavender

Many lavender growers have questions on how to calculate the amount of fertilizer to apply per plant, especially when dealing with small and irregular areas.At a minimum, you need to consider fertilizing an area that includes a strip of grass on each side of the row.If you have drip irrigation, you can fertigate the nitrogen to the plants directly and will only need to consider a small amount of grass on each side of the row (e.g. 15 cm on either side of the row).If you are broadcasting the fertilizer over the grass, then the entire area needs to be considered in the calculation.For fertigated and banded application, fertilize the width of row occupied by the plants at full bloom at a minimum, even if that is wider than the grass strips discussed above.For calculating fertilizer rates, it is best to use the metric system because of the easy conversion between units.Fertilizer to apply in kilograms = ((Length x Width/10,000) * N rate)/(Percent N in Fertilizer/100).Broadcast: Use the calculation as is considering the entire length and width of the planted area.Plants are 2 years old and are approximately 2 ft = 0.6 m wide at full bloom.You plan to band the fertilizer as a granule by hand in the grass on either side of the row.You plan to use a slow release fertilizer, so you do not burn the grass under the band.The fertilizer you have chosen is ESN Polymer Coated Urea which is 44-0-0, which means it is 44% nitrogen.You would also be using a greenhouse grade, water soluble fertilizer such as ammonium nitrate (34-0-0).Later in the summer, increase the amount applied to account for the expanding root zone.Alternatively you can just assume the width of area to fertilize is much smaller (e.g. 30 cm wide strip).The calculations for these nutrients are exactly the same as for nitrogen, but they are best applied ahead of planting to the whole field according to a soil test.For more information on estimating P and K requirements for lavender consult OMAFRA’s Specialty Cropportunities Resource.This is best done by sending a sample of the source to an OMAFRA accredited lab for analysis, because different sources of the same manure or compost type can vary greatly in the amount of nutrients they hold.OMAFRA has some resources that provide average nutrient content of a wide range of manure types.


Growing Lavender

Lavender thrives on full sun (at least 8 hours per day or more), and hot, dry, rocky, or sandy soil.Pruning in the fall will keep the bush compact and help it not to break down in the center as most lavender cultivars are prone to do.Their roots will get as big as the top growth and if you keep it in a container longer, it will die slowly.It’s Simple; just cut, rubber band, and hang upside down in a dark ventilated place.Depending on the size of your bouquets and your climate your bundles will be dry and ready for defoliation in about ten days to two weeks.You can place your dried bouquet in a vase on the mantle or hang it with some lace as a wall decoration.To defoliate wear gloves and hold your bouquet upside down over a bowl and roll it between your hands.Clean the buds you have collected in your bowl by picking out the large stems and leaves and sifting over a screen.First Aid: Apply one drop of lavender essential oil directly to a minor wound after it has been cleaned and dress appropriately.Sunburn: Place 15 drops of lavender essential oil into 1 cup of cold distilled water.For cleaning use 6-10 drops of lavender essential in a spray bottle filled with water and a 1/2 tsp of dish soap.For windows, mix vinegar, water and a few drops of essential oil in a spray bottle.Or place 20 drops of lavender essential oil into a warm tub and relax away the stresses of the day.Insomnia: Apply one drop of lavender essential oil to the corner of your pillow case nightly.Do every night for a week or so and you will eventually train your body to relax when it smells the essential oil.Place in sprayer and spray body to prevent insect bites – great for mosquito protection. .

Fertilizer by Bob Korver : Lavender Association of Colorado

In a study from the Egyptian Journal of Horticulture, optimal yields of aerial parts of lavender were observed following fertilization with urea at 88 lb./ acre.The best yields of essential oil were observed following application of ammonium chloride (N source) at 44 lb/ acre (ElSherbany et al. 1997).Phosphorus: main function to help root development and overall plant health Can be beneficial to add right before blooms begin to give the plant an extra boost Natural sources are bone meal and bat guano (need to check which kind of bat guano).Potassium (also known as potash): key nutrient to boost plants’ tolerance to stress such as varying temperatures or long periods of drought Some growers use higher percentages of potassium to strengthen plant through winter Natural sources include composted fruits and vegetables and kelp meal.Composts Good for adding organic matter to soil; Course composts can increase the porosity of the soil to facilitate the movement of oxygen and water to the plants roots Nutrient content not always known and usually not very concentrated .Need to be sure not high in soluble salts Usually low percentage so if soil is really deficient have to use large quantities.In order to get maximum benefit from manures and fertilizers, they should not only be applied in proper time and in right manner but any other aspects should also be given careful consideration.I) Broadcasting: Even and uniform spreading of manure or fertilizers by hand over the entire surface of field while cultivation or after the seed is sown in standing crop, termed as broad casting.‘Fertigation’ is the technique of supplying dissolved fertiliser to crops through an irrigation system.When combined with an efficient irrigation system nutrients and water can be manipulated and managed to obtain the maximum possible yield of marketable production from a given quantity of these inputs.Continuous small applications of soluble nutrients overcome problems of the fertilizer being washed away or going too deep, save labor, reduce compaction in the field, result in the fertiliser being placed around the plant roots uniformly and allow for rapid uptake of nutrients by the plant.To capitalize on these benefits, particular care should be taken in selecting fertilisers and injection equipment as well as in the management and maintenance of the system.Leaves have a waxy cuticle, which actually restricts the entry of water, nutrients, and other substances into the plant.To a limited extent nutrients applied to leaves can be absorbed and used by the plant, but for the major nutrients (nitrogen, phosphorus, potassium) the quantity absorbed at any one time is small relative to plant needs.If the plant already has plenty of nitrogen, phosphorus, potassium, foliar application will not have any beneficial effects.In fact, if concentrations of nutrients in the foliar spray are too high, then leaf damage can occur and in severe cases may kill the plant.However, with heavier spraying there will be considerable runoff from the foliage and the liquid fertilizer will soak into the soil.From the plant’s perspective, this is essentially the same process that occurs when dry fertilizer is added to the soil.An appropriate time to consider foliar fertilization is when a specific nutrient shortage is evident based on visual symptoms or soil analysis.If a deficiency exists, then foliar application would be one means of providing a quick but temporary fix to the problem.Under high pH conditions, iron chlorosis or interveinal yellowing occurs on young leaves.Chelates are chemical compounds that help iron stay in solution over a wide pH range.So, for all foliar applied products, it is important to include a wetting agent or surfactant to allow for full coverage of the leaf.If rain occurs shortly after an application, most of the spray will be washed off the leaves and reapplication will be necessary.Foliar fertilization is unable to meet the total plant requirements for the major nutrients nitrogen, phosphorus, and potassium. .

How to fertilize lavender

As a Mediterranean plant, it is undemanding and flourishes even in warm summers, as it does not require extra watering or fertilizer.Ideal are slow-acting organic fertilizers such as compost that are mixed in small quantities directly into the plant soil.Horn shavings, Bark mulch, peat and conventional flower fertilizers are not suitable for lavender because of their high nitrogen or acid content.Although the plant substrate leaches out faster in the pot than in the bed and the roots have less room to grow, even here a 14-day lavender fertilization would be more than excessive.For an optimal supply of nutrients in the pot, lavender should be in the right substrate (well drained, loose and calcareous), then a mild re-fertilization twice a year is sufficient. .

Your Ultimate Guide to Planting and Growing Aromatic Lavender

All thrive in full sun and well-drained soil; add organic matter to improve heavy soils, but otherwise, these lovely, fragrant perennial herbs are a cinch to plant, a breeze to grow, and as laid back to preserve as an afternoon in Provence.Lavender is easy to grow in the West’s warm, dry climates, requiring little in the way of pest control, fertilizer, or, once established, water.Its scent is soothing, which is why its essential oil is a prized ingredient in many aromatherapy products, such as lotions and candles.Pruning Tips & Plant Care Irrigate deeply but infrequently, when the soil is almost dry.Snip stems when the bottom third of their blossoms are open; not all blooms are ready to cut at the same time.Lavender is grown for numerous purposes: essential oil, crafting, culinary use; pick the best varieties for your desired use.A sweetly fragrant lavender used for perfume and sachets; also good for flavoring ice cream, jams, meat rubs, and pastries.Riemersma grows ‘Buena Vista’ lavender―with fragrant, dark blue-purple flowers ― because it’s the perfect complement to savory dishes and sweet desserts (Lavandula angustifolia ‘Mun-stead’ and ‘Hidcote’ can also flavor food).She uses it to enhance blackberry jam and shortbread cookies and as a rub (along with rosemary) for cedar-planked salmon with lavender-honey glaze.Unbranched stems rise above fragrant gray-green or silvery foliage; flowers are white, pink, lavender-blue, or various shades of purple.• ‘Grosso’ is a widely planted commercial variety in France and Italy; possibly the most fragrant lavandin of all.• ‘Provence’ may often be described as the perfume lavender, but this selection doesn’t produce the kind of oil used in perfumery (we find it’s better for cookies).If a plant becomes woody and open in the center, remove a few of the oldest branches; take out more when new growth starts.Snip stems when the bottom third of their blossoms are open; not all blooms are ready to cut at the same time. .

Lavender Planting Tips

Planting lavender in your garden can be a rewarding experience not to mention the fabulous aromatic scent filling the air.Lavender is basically a very easy plant to grow, and it has very little needs; it is virtually disease free, and is drought tolerant.Remember lavender is a drought tolerant plant, but will need regular watering for the first 3 months until it becomes acclimated to its new home.If it is lightly damp give it water to make it through the hot days without stressing it.That means do not put it on the same drip system as your roses, trees or any other plant because they will inevitably need more water than your lavender.Lavender does not like for its roots to be kept wet or grown in soggy soil.If your lavender flowers begin to hang their heads and droop, this does not necessarily mean they need water.If it takes longer than 1/2 hour to drain through, you should amend the soil or consider planting somewhere else.If you do not prune, your plant will split apart and grow leggy and not be very attractive. .
