How to Choose the Right Flash Companion Plants for Your Garden

Many factors should be considered when choosing flash companion plants for your garden. First, match the soil conditions that your flash plants require with what is available in your beds. Some prefer well-drained soil while others thrive in moist conditions.

Next, consider the sun exposure for optimal growth. Many flash plants like marigolds and zinnias prefer full sun while others tolerate partial shade. Planting flash companions that match the sun requirements will minimize competition for light.

The climate of your garden region is another factor. Certain flash plants like nasturtiums and petunias thrive in temperate climates while others grow best in tropical conditions.

Finally,consider the specific insects and pests in your garden to determine which flash plants will work best as trap crops or repellents. For example:

  • For aphids, plant zinnias, marigolds or dill.
  • For squash bugs, choose nasturtiums, marigolds or borage.
  • For hornworms, plant cosmos, marigolds or dusty miller.

By considering these key factors, you can better match flash companion plants to your unique garden conditions for maximum effectiveness.

Avoid These 3 Flash Companion Plants That Can Overwhelm Your Garden

Some flash companion plants should be limited or avoided altogether due to their aggressive spreading habit and ability to outcompete weaker plants.

Tithonia (Mexican sunflower) is one such invasiveflash companion plant. It spreads rapidly through underground rhizomes and tall stems that shade out neighboring plants. Tithonia also draws heavily on soil nutrients, leaving less for other companions.

The black-eyed Susan aggressively spreads via rhizomes that form thick mats, crowding out other herbaceous plants. It is best avoided as a flash companion plant unless planted in a confined space.

Similarly, sweet alyssum has a spreading growth habit that allows it to quickly smother slower-growing companions. While its flowers attract beneficial insects, sweet alyssum should be used sparingly and monitored closely to avoid dominating your garden beds.

By remaining aware of aggressive flash companion plants and using them judiciously, you can maintain a balanced garden ecosystem that maximizes the benefits while minimizing competition between plants.

How is data deleted from flash?

Data is deleted by erasing blocks of cells to the all-1s state. But remnants can remain until overwritten. Deleting files does not fully erase data.

What are the disadvantages of flash?

Disadvantages include slower write/erase speeds, finite number of write cycles, data loss if power lost during write, and higher cost than hard disks.

What causes flash memory to fail?

Failure modes include write/erase cycle exhaustion, read disturb errors, data retention loss over time, and write errors or bad blocks.

Is flash memory non-volatile?

Yes, flash memory is non-volatile, meaning it retains data even when power is removed. The trapped electrons on the floating gates stay in place.
