Which plants don’t like egg shells?
Acid-loving plants like blueberries, azaleas, rhododendrons, or camellias should be grown in ericaceous soil, like this Verve Ericaceous Peat-free Compost from B&Q and will not welcome the addition of eggshells to the soil. Eggshells are alkaline and can make the soil less acidic, which these plants do not like. It is advisable to crush and incorporate eggshells into your garden soil regularly, as they provide valuable calcium and minerals that benefit plant growth. Aim to scatter crushed eggshells around your garden every few weeks or as needed.Alternatively, you can add crumbled eggshell directly into the bottoms of your planting holes. It is beneficial to use egg shells when growing your own vegetables like tomato, pepper and aubergine or plants such as roses, hydrangeas, spider plants, ferns and ivy.Adding powdered eggshells to garden beds can provide several benefits for plants. They are rich in calcium carbonate, which is an essential nutrient for plants. They also contain other nutrients like magnesium, phosphorus, potassium, sodium, and organic matter.Eggshells are beneficial for most houseplants, tomatoes, broccoli, and leafy greens as they help strengthen plants, decrease soil acidity, reduce food waste, and prevent blossom end rot. However, they are not recommended for plants that prefer acidic soil, such as blueberries, azaleas, mountain laurel, and pieris.
Which plants benefit from crushed egg shells?
Alternatively, you can add crumbled eggshell directly into the bottoms of your planting holes. It is beneficial to use egg shells when growing your own vegetables like tomato, pepper and aubergine or plants such as roses, hydrangeas, spider plants, ferns and ivy. Remedy #2: Crushed eggshells to prevent blossom end rot in tomatoes. The idea here is that blossom end rot is caused by a calcium deficiency, so adding calcium-rich eggshells to the soil could provide calcium to your tomatoes (or other plants that suffer from blossom end rot).
How often can I put eggshells in my plants?
It is advisable to crush and incorporate eggshells into your garden soil regularly, as they provide valuable calcium and minerals that benefit plant growth. Aim to scatter crushed eggshells around your garden every few weeks or as needed. To transform eggshells into a fine powder, you can use a variety of tools such as a mixer, pestle and mortar, or a blender. After grinding them to the desired size, store the powder in an airtight container. Fine powder helps ensure better absorption by your plants.
Can you put too many eggshells in soil?
Or if you prefer to powder them, a coffee grinder works great. Earthworms love pulverized eggshells. It is unlikely that a dozen or more eggshells per week will cause any problems. They do make the soil more alkaline (raise the pH), but the change (if any) should be negligible. Some plants prefer slightly acidic soil, and adding eggshells can alter soil pH, negatively impacting growth. Composting eggshells is recommended to prevent pests and pathogens while enhancing soil nutrients sustainably.
Why should you never throw away egg shells?
Before you toss those eggshells in the trash, STOP! They’re not waste — they’re a goldmine for your garden!

How long does it take eggshells to decompose in soil?
So using eggshells in compost is a good idea, but it takes between 3 months to a year before it’s converted and usefull for plants. Either way, the calcium contained within becomes available to the soil depending on the soil’s pH balance. The finer the grind the quicker the process can be. Plants like tomatoes, hydrangeas, eggplants, roses, cabbage, squash, and peppers will love the added calcium boost. However, you should avoid using eggshell fertilizer on acid-loving plants, like blueberries, azaleas, and geraniums, if you already have soil that is veering towards alkaline.Other crop plants to prioritise with a dose of egg shells include potatoes, cucumbers, peppers, courgettes, marrows and squash. Avoid adding egg shells in quantity to lime-hating (acid-loving plants) which include blueberries, rhododendrons, pieris and azaleas.
