Calcium is one of the most critical nutrients for healthy plant development, particularly
in fruiting vegetables like tomatoes, peppers, strawberries and courgettes (zucchinis).
A calcium deficiency can result in blossom end rot, a common disorder that causes
dark, sunken spots at the blossom end of your fruit. This condition can leave your
plants looking less than appetising—and feeling like a lot of hard work has gone
to waste.

The good news is that calcium can prevent blossom end rot when used correctly. In
this blog, we’ll cover when and how to use calcium in your garden to keep all your
fruits and vegetables healthy and productive.

### **Why calcium matters for your plants**

Calcium strengthens plant cell walls and growing points, which is crucial for:

 * Developing healthy roots, stems, leaves and fruit
 * Ensuring fruit is firm, crunchy and tasty with no splitting.
 * Improving shelf-life of produce.
 * Improving the overall health of your plants – healthy plants do not attract insect
   pests, and calcium is crucial to mobilising plants’ natural defence systems against
   them.

In fruiting vegetables, calcium is essential during the early stages of fruit development.
Without sufficient calcium, the fruit’s tissues break down, leading to the telltale
symptoms of issues like blossom end rot.

### **When to use ****calcium for your garden**

Calcium can be applied as a foliar or soil application and is easy to apply. Dilute
it in water straight from your watering can or spray it onto foliage or as a powder
sprinkled onto the soil and then watered in.

Biomin Calcium can be applied to vegetables throughout the growing season.  For 
fruit trees or flowering vegetables like courgette, apply within the first three
weeks after flowering. You can apply at any other time with good effect, but these
post-flowering times are when the plant needs calcium the most. For those growing
flowers as a crop or in their garden, apply pre-bloom for strong, tall, upright 
flower stems and blooms with long shelf life.

Our Plant Mineral Bundle makes it easier than ever to ensure your garden plants 
thrive. Containing our glycine-chelated Biomin Calcium to support and fortify plant
growth and resilience, it includes Biomin Booster V for all trace element requirements
often completely overlooked in home garden products and Synergizer, which contains
the three macronutrients, Nitrogen, Phosphorous and Potassium. 

Here’s how you can incorporate these products for the best results in your garden:

These three products are never mixed together but, used in rotation throughout the
growing season, they will ensure your produce is receiving all the nutritional requirements
for healthy growth.

Simply apply 1 product per the label instruction, wait 1 or 2 weeks and apply the
next product and so on.  Ensure you are watering well in between times.

### **Tips for maximising calcium uptake**

While applying calcium is essential, ensuring your plants can absorb it is just 
as critical and therein lies the secret to our Biomin products, they are bio-available
to plants and in turn us. Here are some tips to optimise soil calcium, and nutrient
uptake:

 * **Maintain consistent watering:** Uneven watering is one of the leading causes
   of deficiency. Keep soil evenly moist but not waterlogged.
 * **Mulch your plants:** A layer of mulch helps retain soil moisture and prevent
   fluctuations, creating a stable environment for nutrient absorption.
 * **Handle roots with care:** Damaged roots struggle to absorb nutrients, so be
   gentle when weeding or cultivating near your plants.
 * **Use a bio-available formulation: **Biomin products are one of the very few 
   bio-available and systemic products. 

### **Healthy plants, delicious harvest: Start with calcium**

An important ingredient for solid and productive plants is calcium for your garden.
It’s especially important for preventing blossom end rot and helping your tomatoes,
peppers, and zucchini thrive. Biomin moves throughout the plant to all growing points,
the roots, the shoots and the fruit. Using Biomin Calcium and maintaining essential
minerals with Biomin Booster and Synergizer can set your garden up for success.

Gardening is a journey of growth and learning. With some care and attention, you’ll
soon be harvesting delicious, blemish-free fruits that are as rewarding to pick 
as they are to eat, full of bio-available minerals.

Here’s to a thriving garden and a bountiful harvest!
