Garden fertilizers and other products can help you achieve a beautiful and healthy garden, but if you’ve tried these options and have yet to see results, the problem may be in your soil. Poor soil conditioning or lack of proper nutrients can affect your plants, and if that’s the case, it may be time to use Gypsum

What is Gypsum?

It is a natural soil conditioner made up of calcium and sulphate and can provide a ton of benefits for both small and large gardens. 

How can Gypsum help?

It is an excellent source of calcium

Not only is calcium an essential nutrient for plant growth and development, but calcium will also improve a plant’s ability to take in other essential nutrients like ammonium nitrogen. Calcium cannot move from old to new plant tissues, which is why a constant supply of soluble calcium is required for optimal plant health, and Gypsum can help in this regard. 

Gypsum is made up of 21% calcium and 17% sulphate and is one of the best sources of calcium for any plant in your garden. It can move quickly from the surface of the soil to the roots below and can eliminate symptoms like weak stems, discoloured patches, dead buds and root tips and burnt tips, all of which are indications that a plant is lacking essential calcium.

It provides essential sulphur

Plants need sulphur for protein synthesis, and sulphur is also an important component for nodule formation on legume roots. Adding Gypsum to your garden is a great way to ensure your plants have enough sulphur and that the sulphate in Gypsum is ready for plant absorption right away. 

If you notice plants with a spindly appearance or young leaves that look light green to yellowish in colour or slow growth rate and a delay in plant maturity, these are symptoms of sulphur deficiency, and it may be time to add Gypsum.

It helps break up compacted soil

Tightly packed clay soils can be problematic because water and other essential nutrients will puddle or run off the surface instead of penetrating deep into the soil. Gypsum will loosen these clumps and improve soil structure by making the tightly packed particles into large clumps, which will make the soil more porous and allow air, water and nutrients to penetrate the soil more easily. Gypsum will also help with better root development which will result in stronger and healthier plants. 

It can repair damage from salt

Winter salt can damage a garden, as can de-icing products, and when this salt penetrates the soil, plants will absorb the salt through the roots. Salt can also stunt plant growth or prevent plants from producing flowers or leaves. Gypsum can help reverse this damage as the calcium sulphate combination will replace the excess salt and will heal the plants to encourage new growth.
