Question:
I had an excellent crop of blueberries this year. Should I keep fertilizing them, as the plants still look very lush?Answer:
- The short answer is yes; you should continue feeding blueberries after harvesting the crop.
- Blueberries prefer to be fertilized monthly during the growing season from March through October. They do best with an acid fertilizer, such as Camellia, Azalea, and Rhododendron Food.
- For those who want a more detailed explanation, fertilizers containing Mycorrhizae, such as Dr. Earth or EB Stone Organic, are highly beneficial for blueberries due to their unique root system.
- Unlike most plants, blueberries lack typical "root hairs," which are fine, white fibers that absorb water and nutrients from the soil. To compensate, blueberries form a symbiotic relationship with vesicular-arbuscular mycorrhizal (VAM) fungi.
- The thread-like hyphae of these fungi connect to the plant roots and extend into the soil. These hyphae function as an extension of the roots, absorbing nutrients and delivering them back to the plant.
- In return, the fungi receive sugars from the plant, which are produced through photosynthesis. Mycorrhizae fertilizers help replenish and enhance the naturally occurring fungi in the soil.
- An added advantage for established plants is improved phosphorus absorption, as phosphorus is less mobile in the soil compared to nitrogen. Phosphorus tends to remain near the surface until it is used up by surface roots. It's a critical nutrient for fruit production, but if you're on a regular feeding schedule, this shouldn't be a concern.
- The end of the harvest season is a good time to check the soil pH, as blueberries prefer acidic soil. Early next year, can also work. They thrive in soil with a pH range of 5.0 to 6.6.
- The soil pH can increase during dry seasons, especially if the water quality is marginal or varies.
- An improper pH can affect next year's berry crop. You don't need to have your soil tested in a lab; instead, you can buy a simple pH kit at your local garden center.
- Take three different readings and calculate the average of the results.
- If you need to lower the pH, you can add an acidifier such as Aluminum Sulfate, PH Adjuster, FST, or Soil Sulfur. The amount and frequency depend on the specific product. This helps ensure your plants stay productive year after year.
Question:
I have three Agapanthus plants that are overwhelming my garden. Their roots are spreading into nearby plants, which are struggling as a result. How can I slow down their growth?Answer:
- This problem is fairly easy to solve. Agapanthus, also known as Lily of the Nile, has a fleshy, clumping root system. To control their growth, use a round-nose shovel to cut away the root mass that is encroaching on other plants. You can remove as much or as little as needed, depending on what works best for you.
- Don't worry; you won't harm the main plant. The sections you remove can be replanted or discarded.
