In June, dry fertilizing of onion and garlic can help precisely when the plants are storing strength in the bulbs and heads. A mixture of fine diatomaceous earth, wood ash, and potassium monophosphate supports the soil, supplies potassium with phosphorus, and can contribute to firmer, better storable harvest.<\/p>\n\n\n\n

June is a very important month for onion and garlic. The plants already have green mass formed and gradually transfer energy to the underground part, i.e. to bulbs, cloves, and heads.<\/p>\n\n\n\n

If potassium, phosphorus is missing in this period, or the soil is compacted and without air, the harvest can remain smaller. Dry sprinkling between rows is practical especially after rain or abundant watering, when nutrients start to gradually move to the roots.<\/p>\n\n\n\n

Why dry fertilizing of onion and garlic works precisely in June<\/h3>\n\n\n\n

Dry fertilizing of onion and garlic has the advantage of simplicity. You do not need to infuse, cook, or mix anything in water, just prepare a fine mixture and sprinkle it between rows.<\/p>\n\n\n\n

In June, there is no longer a need to push the plants into excessive leaf growth. Much more important is to support ripening, tissue firmness, head formation, and later storability.<\/p>\n\n\n\n

That is why the mixture should be based mainly on potassium, phosphorus, silicon, and minerals from ash. Use nitrogen in this phase carefully because it can delay ripening and worsen storability.<\/p>\n\n\n\n

First component: fine diatomaceous earth<\/h3>\n\n\n\n

Diatomaceous earth, also known as diatomite, is a fine mineral powder from diatom shells. In the garden, it is used mainly as a soil supplement and source of silicon.<\/p>\n\n\n\n

Silicon helps plants create firmer tissues and can also contribute to better resistance to stress. With onion and garlic, soil structure is also important because compacted soil slows head growth.<\/p>\n\n\n\n

Fine diatomaceous earth can improve permeability and airiness of the top soil layer. It is not, however, a replacement for compost or proper bed preparation.<\/p>\n\n\n\n

Second component: potassium monophosphate<\/h3>\n\n\n\n

Potassium monophosphate is a concentrated fertilizer with phosphorus and potassium content. It is these nutrients that are important for onion and garlic in the final growth phase.<\/p>\n\n\n\n

Phosphorus supports the root system and energy processes in the plant. Potassium helps ripening, tissue firmness, and harvest quality during storage.<\/p>\n\n\n\n

With this fertilizer, it is important not to overdo the dose. It is effective even in a small amount, so it is added to the dry mixture only as a supplement, not as the main mass.<\/p>\n\n\n\n

Third component: clean wood ash<\/h3>\n\n\n\n

Wood ash is a traditional source of potassium, calcium, and several trace elements. With onion and garlic, it can support firmer heads and better ripening.<\/p>\n\n\n\n

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

Ash also increases soil alkalinity. If you have naturally alkaline soil, dose it very carefully or do not use it often.<\/p>\n\n\n\n

How to prepare the dry powder<\/h3>\n\n\n\n

Pour approximately one kilogram of fine garden diatomaceous earth into a plastic bucket. Add five tablespoons of potassium monophosphate and five cups of sifted wood ash.<\/p>\n\n\n\n

Mix everything thoroughly so the concentrated fertilizer is evenly distributed in the whole mixture. It is precisely even mixing that reduces the risk that the dose will be too strong in one place.<\/p>\n\n\n\n

If you have a smaller bed, prepare a smaller amount in the same ratio. You do not have to use the mixture at once, but store it in a dry place and well closed.<\/p>\n\n\n\n

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

When to sprinkle the mixture on the bed<\/h3>\n\n\n\n

The best time is after rain or after abundant watering. The soil is then moist and nutrients start to gradually move to the root zone.<\/p>\n\n\n\n

Do not sprinkle the dry mixture on a completely dry bed during heat. The powder would remain on the surface, could dust, and the effect would be weaker.<\/p>\n\n\n\n

If it does not rain, first water the bed well. Then gently sprinkle the mixture between the rows and, if necessary, carefully work it into the top layer of soil.<\/p>\n\n\n\n

How to apply the sprinkling correctly<\/h3>\n\n\n\n

Sprinkle the mixture between the rows, not directly on the leaves of onion and garlic. The leaves should remain clean, especially if the weather is sunny.<\/p>\n\n\n\n

A thin even layer is enough. The goal is not to create a white carpet, but to give the soil gentle support at the time of head formation.<\/p>\n\n\n\n

After application, you can still lightly water the bed with a gentle shower. This limits dustiness and helps the mixture get closer to the roots.<\/p>\n\n\n\n

Why the mixture can also help with diseases<\/h3>\n\n\n\n

Diatomaceous earth and ash can improve the soil surface and reduce moisture in the top layer. A drier and airier surface is less favorable for some fungal problems.<\/p>\n\n\n\n

Ash also contains minerals that support plant firmness. A stronger plant usually handles pressure from diseases and stress better.<\/p>\n\n\n\n

It should not be claimed, however, that the mixture cures all diseases. If the stand is affected by rot, mold, or pests, remove the affected parts and solve the cause.<\/p>\n\n\n\n

What to watch with garlic<\/h3>\n\n\n\n

Garlic in June often forms flower stalks. If you grow hardneck garlic and want larger heads, break off or cut the flower stalks in time.<\/p>\n\n\n\n

The plant then does not send energy to the flower, but to the head. The dry sprinkling then has greater importance because you support the phase in which garlic actively enlarges the cloves.<\/p>\n\n\n\n

After removing the flower stalks, however, do not overwater the garlic. It needs regular moisture, but not standing water.<\/p>\n\n\n\n

What to watch with onion<\/h3>\n\n\n\n

Onion does not like excess nitrogen in the later growth phase. If you overdo it with nitrogen fertilizer in June, it can grow into foliage and ripen worse.<\/p>\n\n\n\n

When the onion starts to form, focus on potassium, phosphorus, and good soil structure. That is why the dry mixture with ash and diatomaceous earth makes sense.<\/p>\n\n\n\n

Do not dig the onion out of the soil unnecessarily early. Let it ripen naturally until the foliage starts to lie down and yellow.<\/p>\n\n\n\n

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

If the soil is significantly alkaline, ash can worsen the problem. In that case, use rather less ash or focus on compost and potassium fertilizer without further increasing pH.<\/p>\n\n\n\n

Do not use the mixture shortly before harvest in a large dose. At the end, the plants already need mainly to ripen and dry, not another strong intervention.<\/p>\n\n\n\n

Avoid application on wet leaves during sun. The powder should go to the soil between rows, not on the green parts of the plants.<\/p>\n\n\n\n

Most common mistakes with dry fertilizing<\/h3>\n\n\n\n
    \n
  • Sprinkling the mixture directly on leaves and not between rows.<\/li>\n\n\n\n
  • Using too much ash regardless of soil pH.<\/li>\n\n\n\n
  • Adding more potassium monophosphate than the plants need.<\/li>\n\n\n\n
  • Applying the sprinkling on completely dry soil without subsequent watering.<\/li>\n\n\n\n
  • Expecting that the mixture will replace a healthy bed, crop rotation, and appropriate watering.<\/li>\n<\/ul>\n\n\n\n

    Simple procedure for a June bed<\/h3>\n\n\n\n

    First weed the bed and carefully loosen the space between rows. Do not intervene deeply so you do not damage the roots of onion and garlic.<\/p>\n\n\n\n

    After rain or watering, sprinkle a thin layer of the prepared mixture between the rows. If necessary, gently work it into the soil surface and water lightly once more.<\/p>\n\n\n\n

    Then just monitor the plants. If the leaves look healthy and the heads are enlarging, further strong fertilizing is not necessary.<\/p>\n\n\n\n

    Large heads begin in the soil<\/h3>\n\n\n\n

    Dry fertilizing of onion and garlic in June is a simple way to support the formation of large, firm, and better storable heads. Diatomaceous earth improves the soil environment, ash supplies minerals, and potassium monophosphate adds important phosphorus with potassium.<\/p>\n\n\n\n

    The best results, however, are achieved only when you use the mixture in moderation, on moist soil, and between rows. Onion and garlic do not need exaggerated interventions, but balanced support at the right time.<\/p>\n","protected":false},"excerpt":{"rendered":"
