Pumpkin fertilizer - so you fertilize your pumpkin plants properly: fertilizer

Pumpkin fertilizers, whether in organic or mineral form, have all the advantages and disadvantages. Before deciding on a fertilizer, a previous soil analysis is recommended. In addition to the optimal fertilizer, the maintenance of the crop rotation also plays an important role for a splendid growth of pumpkins. So edible pumpkin varieties should not be planted in the immediate vicinity of ornamental pumpkins, for pumpkins are incompatible with each other just as with other cucurbits to which include melons and cucumbers.

Basic fertilization before planting

Much of the fertilizer should be incorporated into the soil prior to planting in pumpkin growing, such as e.g. Compost, manure, cattle or horse manure or other organic or mineral fertilizers from specialist retailers. This fertilization is called basic fertilization. The best time for a basic fertilization is in autumn or early spring. Now the pumpkin needs a nitrogen-stressed pumpkin fertilizer. On a square meter one expects 60 g of compost, manure, horn shavings or green manure. For mineral fertilizers 80 g per square meter. This dosage is sufficient for about 6 weeks. After these 6 weeks a potassium fertilizer should be given, because the needs of pumpkins change with increasing maturity.
In winter, another dose of potash fertilizer is recommended. Particularly advantageous is the planting on a surface on which previously green manure plants have stood. These plants enrich the soil with humus and nitrogen, prevent the washing out of nutrients, loosen the crop rotation, fight damaging nematodes and generally contribute to soil recovery.
Tip: Freshly limed soils should be avoided, as pumpkins are very sensitive to this. When buying mineral fertilizers always pay attention to a high nitrogen content.

Top dressing of pumpkin plants

Starvation pumpkins need enough nutrients throughout the growth and flowering period from May to September. Distributed over the entire vegetation period, at least three head fertilizers should be made. Especially good work does compost. But also planting, for example, stinging nettles or slightly soluble mineral salts in solid or liquid form are suitable. With organic fertilizer one expects 20 g and with mineral 40 g per square meter. Jauchen or mineral salts are highly corrosive, as a result, no fertilizer should reach the leaves or the green parts of plants. If you only want to use compost, it should be well-matured and administered about every 14 days, about 3-5 liters per square meter.
Tip: One should be careful not to fertilize too nitrogen-stressed, because that could cause the fruits to burst.

Optimal fertilization directly on the compost heap

A compost pile or a place right next to it offers optimal soil conditions for pumpkins, because they find all the important nutrients in sufficient concentration there. In addition, the tendrils and leaves of these plants hide the compost pile in a very decorative way. However, the compost should be evenly moist, but not too moist, because too much moisture displaces the oxygen from the compost. To protect it from too much moisture, it can be covered with a special compost canvas that is breathable and allows only a small amount of rainwater. Heavy rainfall bounces off.
Another advantage of such a tarpaulin is the UV protection, so that the compost does not dry out so quickly in the summer. In addition to the fact that compost is a very good pumpkin fertilizer, it provides both moisture and heat both important prerequisites for pumpkin cultivation. A disadvantage of this type of planting is that the plants extract from the compost a large part of the nutrients, so that it can no longer be used as a soil conditioner for other areas. For this reason, it is not advisable to grow pumpkins every year on the same compost heap. It is best to plant it right next to it, so that the nutrients are contained in the compost and the pumpkin still benefits from it.
Tip: When planting on the compost heap, additional mineral fertilizer can be dispensed with.

Blue Grain as pumpkin fertilizer

  • Blue Grain is a mineral fertilizer.
  • Is particularly suitable for plants that are to develop many flowers or fruits such as cucumbers or pumpkins.
  • It should be particularly effective, if it is used purposefully.
  • Phosphate and nitrate are contained in a particularly high concentration.
  • Also, potash and trace elements are among the ingredients.
  • Blue seed in small doses at least 3 weeks before sowing or planting.
  • Blue Grain can also be used for head dressings.
  • Blue seed can easily overfertilize.
  • This results in a high nitrate pollution of the soil.
  • In case of doubt better to resort to natural alternatives.
  • Their effect is sometimes somewhat less but completely sufficient and also harmless.
Tip: Caution should be exercised with children and pets as it may be dangerous for them to come into contact with blue-grain.

Advantages and disadvantages of organic fertilization

Organic fertilizers are a good alternative to mineral fertilizers. They are basically of natural origin and improve the humus supply in the soil, they compensate for nutrient losses and support soil life and soil health. Again, there are fertilizers with long-term effects such. Compost, horn shavings, stinging nettle or green manure. Organic fertilizers are not immediately available to the plant, but must first be transformed by microorganisms or made available to plants by gradually dissolving the minerals. With acute nutrient deficiencies in the soil, these fertilizers are rather less suitable.

Advantages and disadvantages of mineral fertilizer

Mineral or inorganic fertilizers are produced industrially and chemically from natural minerals. They are readily soluble in water and act very fast, unlike organic fertilizers. This is especially advantageous if the plants in question already have deficiency symptoms. These fertilizers have a long-term effect, but there is a risk of over-fertilization. Accordingly, mineral fertilizers such as blue-grain should be administered only in small quantities, but more frequently. Even a mixture with compost can be useful.
Tip: In order to be able to determine the existing nutrient concentration in the soil or the actual requirement, a soil analysis is recommended. This can avoid an excessive supply but also a depletion of the soil.
ConclusionWhich type of pumpkin fertilizer you ultimately choose is left to each self. It is important what is to be achieved with the fertilizer. With the right dosage you can achieve good to very good results with any fertilizer. For the sake of the environment, however, organic fertilizers are to be preferred.

Worth knowing about natural pumpkin fertilizer

  • Pumpkins are so-called starvationers. So they consume a lot of valuable nutrients from the soil.
  • Therefore, proper fertilization is very important for optimal growth of the plant as well as the fruits.
  • However, you also need a little sensitivity when fertilizing, because not every fertilizer is suitable.
  • In principle, ornamental gourds are also fertilized differently than vegetable gourds.
  • Pumpkins grow and thrive on compost heaps. Such provides all the necessary nutrients at once.
  • Nevertheless, it should not be grown every year on the same compost heap, as this may lead to worse results.
  • Of course, compost is also suitable as fertilizer in the field or in the bed.
  • Sometimes there is also the possibility to get green waste directly from the disposal station.
  • The location of the compost also plays a role. He should stand in the sun, but also protected from the wind, because pumpkins like it warm.
Tip: If you want to use other fertilizer in addition to the compost, make sure that it is suitable for food. If ornamental pumpkins are to be fertilized, this is not very important. When fertilizer should then be paid to adequate nitrogen intake as well as sufficient amount of potassium.
