Carrot fertilizer does not have to be expensive or complicated, but it must support mainly the root, not only the green foliage. If you give carrot loose soil, a mild dose of nutrients between rows and correct timing, it will reward you with larger, sweeter and straighter roots.<\/p>\n\n\n\n

Carrot can trouble even an experienced grower. In spring it germinates nicely, the foliage looks healthy, but at harvest come thin, short or cracked roots.<\/p>\n\n\n\n

Often there is not one big mistake behind it, but several small ones at once. Too heavy soil, dense sowing, a lot of nitrogen and uneven watering can spoil even a very promising bed.<\/p>\n\n\n\n

Why carrot does not grow large and sweet<\/h3>\n\n\n\n

Carrot needs soil into which the root penetrates easily and without obstacles. If it hits a stone, clod or fresh manure, it often branches and loses nice shape.<\/p>\n\n\n\n

Equally important is thinning. When plants grow too densely, the roots compete for space, water and nutrients.<\/p>\n\n\n\n

The biggest mistake is excess nitrogen. Carrot then creates lush foliage, but the root remains weaker, more watery or less storable.<\/p>\n\n\n\n

Carrot fertilizer with reasonable dosing<\/h3>\n\n\n\n

Carrot fertilizer should support mainly root development. That is why phosphorus, potassium and a gentle dose of micronutrients are important, not strong nitrogen nutrition.<\/p>\n\n\n\n

Apply the nutrition between rows, never directly on young roots. Delicate small plants can be damaged by strong concentration and growth will stop for a while.<\/p>\n\n\n\n

The best is to fertilize when carrot has several true leaves and you already see the rows well. The soil should be mildly moist so nutrients gradually get to the roots.<\/p>\n\n\n\n

Mustard powder as a supplement between rows<\/h3>\n\n\n\n

Mustard powder is used in the garden mainly for its pronounced aroma. It can help make the environment unpleasant for some pests and at the same time it is easily worked into the soil surface.<\/p>\n\n\n\n

Do not use it in thick layers. For an ordinary meter of row a small pinch to half a teaspoon is enough, scattered into the soil between plants.<\/p>\n\n\n\n

After application gently loosen the soil and water. Mustard powder should be only a supplement, not the main component of nutrition for the whole bed.<\/p>\n\n\n\n

Ash supplies potassium, but needs caution<\/h3>\n\n\n\n

Wood ash is a known source of potassium, calcium and other mineral substances. With carrot it can support root firmness and better ripening of the harvest.<\/p>\n\n\n\n

Use only ash from clean, unpainted and chemically untreated wood. Ash from coal, briquettes, colored paper or waste does not belong in the garden.<\/p>\n\n\n\n

For one square meter of bed one thin handful of sifted ash is enough. If you have alkaline soil or regularly lime, rather significantly limit ash.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Why phosphorus and potassium are needed<\/h3>\n\n\n\n

Phosphorus helps the root system and is important especially in the period when young carrot starts. Without it the root can grow slowly and the plant uses other nutrients worse.<\/p>\n\n\n\n

Potassium supports root quality, taste, firmness and resistance to stress. With root vegetables it is therefore more valuable than high doses of nitrogen.<\/p>\n\n\n\n

If you use multi-component fertilizer, choose one that does not have too high a share of nitrogen. In the second half of carrot growth it is better to minimize nitrogen and focus on the root.<\/p>\n\n\n\n

Simple mixture for an ordinary bed<\/h3>\n\n\n\n

For a small bed prepare a mixture from sifted wood ash, a very small amount of mustard powder and a gentle dose of fertilizer with lower nitrogen. The goal is not to create a strong concentrate, but even support.<\/p>\n\n\n\n

For one square meter use approximately one thin handful of ash, one teaspoon of mustard powder and the amount of multi-component fertilizer according to the lower limit of the recommendation on the package. Mix everything with dry sand or fine soil so the mixture distributes evenly.<\/p>\n\n\n\n

Sprinkle it only between rows and shallowly work it in. Then water the bed with a gentle shower so the surface does not wash away.<\/p>\n\n\n\n

When not to use the mixture<\/h3>\n\n\n\n

Do not fertilize freshly germinated carrot with strong mixtures. Young roots are sensitive and need especially moisture, light, airy soil and time.<\/p>\n\n\n\n

Avoid fertilizing during heatwaves when the soil is hot and dry. First water the bed in the evening and add nutrition only the next day when the plants are not stressed.<\/p>\n\n\n\n

Do not use the mixture when you added a lot of mineral fertilizer before sowing. Excess nutrients can cause deformations, worse taste and weaker storability.<\/p>\n\n\n\n

Carrot fly and protection with smell<\/h3>\n\n\n\n

Carrot fly belongs among the most unpleasant pests of carrot. Larvae damage roots, create tunnels and the harvest then becomes bitter or rots.<\/p>\n\n\n\n

Strong smells can help mask the smell of carrot, especially after thinning or hoeing. Use mustard powder therefore rather as part of wider protection, not as the only weapon.<\/p>\n\n\n\n

Covering the bed with fine netting, crop rotation and growing onion or leek nearby also helps. After thinning remove the pulled plants from the bed so they do not attract the pest with smell.<\/p>\n\n\n\n

Loosening the soil is as important as nutrition<\/h3>\n\n\n\n

Carrot needs a free path downward. If the soil is compacted, the root turns, shortens or branches.<\/p>\n\n\n\n

Loosen between rows only shallowly so you do not damage the roots. The surface crust after rain prevents air access and worsens water uptake.<\/p>\n\n\n\n

Improve heavy soil with compost and sand before sowing. After germination do not dig the soil deeply at the roots so you do not damage the plants.<\/p>\n\n\n\n

Watering decides about taste and cracking<\/h3>\n\n\n\n

Carrot needs even moisture. Long drought and subsequent strong overwatering often causes root cracking.<\/p>\n\n\n\n

Water slowly and deeply so water penetrates to the roots. Surface sprinkling supports only shallow roots and the bed dries quickly again.<\/p>\n\n\n\n

During root enlargement even moisture is extraordinarily important. It is then that the size, juiciness and gentle sweetness of the harvest is decided.<\/p>\n\n\n\n

Micronutrients that are forgotten<\/h3>\n\n\n\n

Carrot also uses small amounts of boron, manganese and molybdenum. These elements are enough in low doses, but with their deficiency growth can be weaker.<\/p>\n\n\n\n

If you buy multi-component fertilizer, choose one that also contains micronutrients. Do not exceed the dose because with trace elements it holds that little helps and much can harm.<\/p>\n\n\n\n

With naturally fertile soil compost and mild mineral support is often enough. Every bed is different, so monitor the plants, not only general instructions.<\/p>\n\n\n\n

Practical procedure step by step<\/h3>\n\n\n\n
    \n
  • First thin the carrot so the plants have space for root growth.<\/li>\n\n\n\n
  • Gently water the bed before fertilizing, especially if the soil is dry.<\/li>\n\n\n\n
  • Sprinkle the mixture only between rows, not directly on the plants.<\/li>\n\n\n\n
  • Loosen the soil shallowly and distribute the nutrition evenly.<\/li>\n\n\n\n
  • After application water with a gentle stream of water.<\/li>\n<\/ul>\n\n\n\n

    Most common mistakes when fertilizing carrot<\/h3>\n\n\n\n

    The first mistake is a lot of nitrogen. The foliage then looks beautiful, but the root lags and the harvest can be less sweet.<\/p>\n\n\n\n

    The second mistake is application of fertilizer directly at plant necks. A stronger mixture can burn young roots or slow their growth.<\/p>\n\n\n\n

    The third mistake is forgetting about the soil. Even the best fertilizer will not help if carrot grows in compacted soil full of stones and fresh organic matter.<\/p>\n\n\n\n

    Large carrot needs balance<\/h3>\n\n\n\n

    Carrot fertilizer works best when it supports the root and does not overdo foliage growth. Ash, mild dose of phosphorus and potassium and a pinch of mustard powder can help if you use them between rows and in small amounts.<\/p>\n\n\n\n

    The nicest roots grow in loose beds with regular moisture and enough space. When you combine reasonable nutrition, thinning and protection from pests, carrot can pleasantly surprise you at harvest.<\/p>\n","protected":false},"excerpt":{"rendered":"
