Growing an Avocado From Seed Q&A

Q: Can I grow an avocado tree indoors year-round?

A: Yes, you can! But keep in mind, avocado trees need a lot of light. Make sure to place it in a sunny spot (preferably south-facing) or use a grow light to help it thrive indoors.

Q: Are avocado trees self-pollinating?

A: Yes, avocado trees are self-pollinating, meaning they don’t need another tree to produce fruit. However, having two trees can improve fruit production by increasing pollination.

Q: How much space do I need to plant an avocado tree?

A: Avocado trees need a lot of room to grow—expect them to reach 30-40 feet tall and 20-30 feet wide! Be sure to plant them at least 15-20 feet away from other trees, structures, or fences to give them room to spread out.

Perennial Herbs For Your Garden Q&A

Q: What’s the difference between a perennial and an annual medicinal herb?

A: Perennial herbs come back year after year, so once you plant them, you’ll have them for a long time! Annual herbs, on the other hand, only last for one growing season, so you’ll need to replant them each year. Perennials like mint, echinacea, and yarrow save you the hassle of replanting every spring.

Q: How can I harvest medicinal herbs without killing the plant?

A: The key is to harvest selectively! Only take what you need from each plant—this lets it continue to grow and regenerate. For herbs like mint and sage, you can snip off the top leaves regularly to encourage fresh growth. For larger plants like echinacea or valerian, cut back the flowers once they’ve bloomed to keep the plant healthy.

Q: What’s the best way to use my herbs for medicinal purposes?

A: There are tons of ways to use your medicinal herbs! Fresh leaves can be used in teas, tinctures, or poultices. Dried herbs ar

Early Spring Blue Flowers Q&A

Q: Are early spring blue flowers annuals or perennials?

A: Most early spring blue flowers like Crocus and Iris reticulata are perennials. They come back every year, giving you reliable, beautiful blooms each spring. However, some, like Scilla and Chionodoxa, are typically planted as perennials, too, but depending on your climate, you may treat them as annuals if they don’t come back reliably in colder areas.

Q: Aside from blue flowers, are there any white flowers that bloom in early spring?

A: Absolutely! If you’re looking to mix things up, there are some gorgeous white flowers that bloom just as early as blue ones. Snowdrops are a classic—these delicate flowers pop up right when the snow is melting. Anemone is another great option; it has simple, pure white blooms that are perfect for adding a clean, crisp touch to your spring garden.

Q: What’s the best way to combine white and blue flowers in my garden?

A: For a stunning contrast, try planting blue ones like Crocus and Iris reticulata next to white ones like Anemone or Lily of the Valley. The combination of the cool blues with the fresh white blooms will create a striking visual impact. You can also create a natural look by planting them in clusters or drifts across your garden.
