Q: What’s one thing I can do right now to improve my garden’s health?
A: Mulch is key. It helps with moisture retention, keeps weeds down and improves the soil. You can also start planting cover crops like barley or alfalfa, which will naturally enrich your soil for next season. (Carlsbad residents can pick up free mulch at Palomar Transfer Station, 5960 El Camino Real, Monday through Saturday between 8 a.m. and 3 p.m.)
Q: How can I control pests without using harmful chemicals?
A: For aphids, a high-pressure water spray works wonders. You can also use neem oil or insecticidal soap, both of which are safe and effective. For ants, try diatomaceous earth, which is non-toxic but effective.
Q: My tomato plants didn’t do well this summer. What went wrong, and what can I do next season?
A: Tomatoes need heat and sunshine to grow well, and we didn’t get as much of that with May gray and June gloom this year. Next season, try rotating where you plant them to avoid soil diseases and be sure to use mulch to help retain moisture.

What to plant this time of year
Carlsbad’s Mediterranean climate provides nearly year-round opportunities for planting, but fall is one of the best times to refresh your garden. Here are some plants that gardeners typically grow in the fall:
- Leafy greens like lettuce and spinach
- Cruciferous vegetables like broccoli, cauliflower, Brussels sprouts and beets
- Pumpkin, butternut squash and other rare squash varieties
- Herbs like parsley and thyme
More gardening resources
The library will host more Grow Your Garden events next year. In the meantime, the Carlsbad Library offers a collection of gardening books covering everything from basics to more advanced techniques. Dana, who has read much of the collection, recommends gardeners of all levels take advantage of this resource.
The library also has a seed library where you can pick up seeds to grow in your garden.
