Potassium-Magnesium 1kg – The Secret to Quality Harvest and Sweet Fruits

Have you noticed tomato flowers dropping, potatoes not storing well, or plant leaves turning yellowish/brown between the veins? These are clear signs of potassium or magnesium deficiency.

Potassium-Magnesium is a special water-soluble mineral fertilizer that doesn’t just make plants grow, but makes them fruit and strengthens their health. It’s an indispensable supplementary fertilizer for every serious gardener.

Why do your plants need Potassium-Magnesium?

1. Tomatoes and Cucumbers (Yield):

   • Helps prevent tomato flower drop, a common problem in greenhouses.

   • Promotes even fruit ripening and reduces green shoulder development.

2. Potatoes and Vegetables (Taste and Storability):

   • Potassium is the “flavor element.” It increases potato starch content and improves vegetable flavor.

   • Strengthens the skin and improves winter storability of the harvest.

3. Green Leaves (Photosynthesis):

   • Magnesium is the core of chlorophyll – it makes plants deep green and vibrant again, preventing magnesium deficiency-induced chlorosis (leaf spotting).

4. Grapevines and Roses (Winter Hardiness):

   • This fertilizer is an excellent autumn helper. Using it in August helps grapevine and rose stems lignify, ensuring plants survive winter without damage.

Fast Action

The nutrients are present as sulfates in the fertilizer. This means they dissolve quickly in soil moisture and are immediately available to plants – unlike many other granules that can take months to act.

The fertilizer can be used throughout the season (March to August), 2–3 times during the period. Spread the granules evenly on the soil surface, lightly mix them in, and water.

Easy to Measure:

• 20–25 g = about half a handful.

• 40 g = approximately one handful.

Exact Application Rates per Crop:

Plants	Rate (g/m² or per plant)	Recommendation
Greenhouse (Tomato, cucumber, pepper, grapevine)	30–40 g	Fertilize during flowering and at the start of fruit ripening.
Berry Crops (Strawberry, raspberry, blueberry)	30–40 g	Improves berry sweetness.
Outdoor Vegetables (Potato, cabbage, onion)	80–100 g	Crucial for improving potato quality.
Fruit Trees (Apple trees, stone fruits)	40–60 g	Especially recommended for sweet cherries.
Lawns	25–35 g	Gives the lawn a vibrant green color.
Plants with Deficiency Symptoms	80–100 g	“First aid” for yellow leaves.

Grape Grower’s Reminder:

Start fertilizing grapevines in August (1–2 times) to promote shoot lignification before frosts.

Note: Keep out of reach of children and pets.
