How to Know that Your Strawberry Needs Fertilizer?
Fertilizer plays a significant role in promoting overall plant growth and getting tasty, juicy strawberries. When strawberry needs fertilizer, they show some signs for you. You need to understand what these signs mean. Let’s know the signs –
Yellow or Pale Green-colored Leaves: Your strawberry leaves may turn yellow or pale green instead of green. When it happens, they give you a signal that they need help. Enough nutrient deficiency is one of the main reasons behind yellowing. You need to supply essential nutrients through well-balanced fertilizers and also plant foods.
Not Flowering: It can be frustrating to find your plants without flowers. Despite enough green leaves and healthy growth, it occurs because of fertilizer shortage. Immediately fertilize your plants to get flower production.
No Berries: Whenever you notice a lot of attractive flowers in your favorite plant but not enough production of berries, consider applying fertilizer.
When to Fertilize Strawberry Plants?
Spring would be the perfect time for fertilizing any plant. However, you can decide any time after summer and before September. This is the ideal term to do some fertilization.
When you are fertilizing is the core of making it work at its best. The season and environment will be significant factors in the growth of suitable fruits.
You can do fertilizing when this is super summer. Besides, the rainy season will wash out all the soil nutrition before mixing it up.
Besides, spring is the time when strawberry plants require more nitrogen. That’s the reason experts suggest fertilization by the months of spring.
The grown strawberry plants will require fertilization once every year. But the little one would require fertilization and care more than usual.
You should mix the fertilizer after one month of the plantation. But make sure you’re not mixing too much of it.
How to fertilize Strawberry Plants?
How you fertilize your strawberry plants depends on the plant’s growth and the environment.
We already know that strawberry plants mainly rely on nitrogen. Especially when it’s early spring and late fall, good fertilizing can boost growth.
But whenever you fertilize, ensure you’re taking the right amount. The growth stage of a plant is more sensitive. If you mix too much fertilizer, it might make the soil toxic for the little plant.
The basic rule here would be, to mix about 1 pound of fertilizer for each 20-foot height of the plant. This might take one month to grow after plantation.
For better and more detailed instructions, follow the directions written on your fertilizer package.
How Often to Fertilize Strawberries?
Strawberries require fertilizer to increase their developing power. Timing plays a significant role in this case. You should fertilize strawberries in early spring and late fall. Consider applying fertilizer at least once in a growing season.
After one month from the planting time of your favorite plant, apply fertilizer. When you notice that your strawberry gets matured, fertilize it again to get the best result.
Don’t fertilize too early or too late. Stop fertilizing a couple of weeks before harvesting. I would like to suggest fertilizing plants again after harvesting so that they can get back their vitality.
Do Strawberries Like Acidic Soil?
Yes, strawberries are acid-loving plants. They prefer acidic soil to bloom well and produce more berries. In many cases, you may not get proper growth and enough blooming of strawberries because of cultivating them in less acidic soil. They may even die off before harvesting time.
Before planting strawberries, testing the soil pH is a must. If the pH ranges between 5.5- 6.5, no doubt, they will grow well. But if you find the garden soil less acidic, you can add coffee grounds to increase soil acidity. On the other hand, add lime to reduce soil acidity.
Do Strawberry Plants Like Coffee Grounds?
Coffee grounds increase soil acidity and supply essential nutrients to your plant. Strawberries require nitrogen. Coffee grounds are a great source of nitrogen. It helps to grow your strawberries large and healthy. If you face a waterlogged problem in your strawberry garden, this application can also help to make a good drainage system.
Coffee grounds are good for pest and disease control. Its caffeine content may kill beneficial insects, alongside harmful pests. Properly compost your coffee grounds before applying them to avoid damaging the plant. Avoid excessive use of coffee grounds.
