You want to keep your indoor plants healthy and thriving all year round, but they can be a challenge when they start lacking nutrients. Since they survive in containers, they’ll eventually pull all of the nutrients out of the soil and start to weaken, rot, and die unless you fix it. You can help them by adding fertilizer periodically, and you should make a point to mix blood meal into your plant’s soil. You can add it annually or bi-annually to help your plants recover from illnesses. It’s especially important if your plants are wilted or showing brown spots on the leaves.
Blood meal will help the nutrients in your soil break down quicker, and this can rush a nutrient boost to your plant’s roots. It’s very effective if you add blood meal and fertilize your plants a few days later. The nutrients can help perk up your plants, kickstart their growth, and keep them looking lush and full all year round. Additionally, blood meal works on almost any type of plant without being too strong for them to handle. You can use it on succulents, hanging plants, cacti, exotics, and more. I’ve picked out 10 of the best blood meal products and reviewed them for you. You can take these reviews and the short buyer’s guide to help you narrow down your choices.
Keeping your indoor plants healthy and happy can be a challenge because they have limited nutrients in their pots, and there is no steady stream to keep the lush and green. This is why you should make a point to refresh the soil once or twice a year to boost the nutrient content.

Blood Meal Buyer’s Guide
If you’re considering incorporating blood meal into your plants, you have to know what to consider when you start shopping. A short buying guide can help you compare the various products and sift through the product reviews until you narrow down the choice that will work best to give your houseplants a needed nutrient boost to keep them healthy and thriving all year round.
Defining Blood Meal
This product is an upgraded form of traditional fertilizer, and it gives your plants a slow-release of nitrogen when you mix it into your plant’s soil. This is a huge source of nutrients for your plants because animal blood has higher levels of nitrogen and proteins. It is dried and powdered blood from cows or other slaughtered animals, and it’s very popular to mix into vegetable and fruit plants. You can also create a liquid fertilizer with it because this type of meal is water-soluble.
Once you purchase it, you should read the dosage instructions very thoroughly. If you accidentally get it on your plant leaves, it’s strong enough to burn them and cause more damage. To use it, you want to mix it into the first few inches of soil and water it. The water will help push the meal down to your plant’s roots to help them absorb more nutrients.
Matching the types of indoor plants you have to your blood meal will help ensure that it’ll create an optimal growing environment for them, and you should avoid getting anything on the leaves because it can burn them.
The brand you choose is very important because more well-known ones tend to pay more attention to the ingredients. It’s also easier to get in touch with a brand if you have problems. Maybe you’re curious as to whether or not a brand will do well with your indoor orange trees or if you should pick something else. The customer service team will be able to advise you on which product would work best for your plants.
Stronger formulas will cover more area, both inside and out. The average coverage area hovers right around 100 to 200 square feet, and this works out to a teaspoon or less per plant. If you don’t have a lot of houseplants, you could get at least a year out of a single purchase. This includes reapplying the product every few months to encourage continued growth and the dark, green coloring.
As with any type of fertilizer, you’ll need to add water to help it start working and sink to the roots of your plants. Each time you water, the fertilizer will encourage your plants to absorb as many nutrients as possible to green up the leaves and help them grow.
How do you apply your meal? For the most part, many companies recommend that you mix the product into your soil before you plant your indoor plants. Once you apply it and get the plant in the pot, you should apply a light layer of water. Also, make sure you double-check the recommendations for reapplying it. Larger tomato plants will most likely need more meal than smaller succulents to make it last for a few weeks before you have to reapply it.
Benefits of Using Blood Meal
There are many benefits of adding blood meal to your plants to help encourage healthier, greener growth and blooms with higher yields. This is a very affordable organic fertilizer that gives all of your plants a big boost of nitrogen. A few benefits of adding blood meal to your plants include:
1. Improves Soil Quality
Blood meal is a fantastic way to improve your soil quality because it helps balance the nutrient content. When the active growing season comes around, it’s not uncommon for your garden area to run low on essential nutrients because your plants use it. Once you incorporate blood meal into the garden, it makes the soil return to a natural balance. In turn, this will keep the soil nourishing your plants’ root systems.
2. Rich Nitrogen Source
Blood meal gives you plants and the soil a consistent, rich source of nitrogen. Higher nitrogen levels can increase the soil’s acidity levels, and this is a great thing for crops like peppers, squash, onions, and radishes. If you plan on having a vegetable garden, you’ll need a higher amount of nitrogen to nourish all of your plant’s roots quickly.
3. Balances the Carbon to Nitrogen Ratio
If you have a compost pile to use to enrich your soil, you can add blood meal to it to help balance out the carbon to nitrogen ratio. Any brown material present in your compost pile like the dried, wilted leaves, straw, or paper, all contain carbon. Adding blood meal to this compost pile will ensure that you get a balanced nutrient dose to add to your soil.
4. An Attractive, Lush Garden
Gardeners will notice that you have a visible difference in how green your plants are after you enrich the soil with blood meal. Since it is high in nutrients, it helps to produce plentiful, lush, and deep green foliage on all of your plants. Blood meal is ideal for helping you get long-lasting deep green coloring.
It could also attract butterflies and birds by encouraging healthy flowers. It works even better when you apply it to your vegetable gardens with Brussel sprouts, kale, lettuce, and other heavy feeders. They’re nitrogen-hungry, so they need extended nitrogen to have a full harvest.
Blood meal is an organic way to help your plants stay healthy while giving them a boost of nutrients. I’ve given you 10 different options from various brands that you can compare side-by-side to see whether or not they’ll work well for your indoor plants. You can use the buying guide to narrow down your choices and make the best selection for your needs to keep your indoor plants looking lush and healthy 365 days a year.
