April and May Gardening Tips
Prepared by the Alameda County Master Gardeners
Spring Months: April and May are among the busiest months for gardeners. Almost all warm season vegetables, herbs and annual flowers are planted.
- Continue to plant root crops in the garden (beets, turnips, carrots, radishes, potatoes, etc.).
- Set out plants or seed directly summer annuals (cosmos, marigold, sunflower, petunia, etc.).
- Some cool season crops can still be planted in early April (chard, leek, green onion, lettuce, other salad greens).
- Summer crops can possibly be planted in late April if it’s warm enough. Start cucumbers, squash, pumpkins and melons indoors in peat or newspaper pots.
- Plant summer bulbs (callas, cannas, dahlias, gladiolas, etc.).
- Fertilize and water as needed.
- Manage any pests who have appeared with help from UC Pest Notes.
- All summer vegetables can be planted (beans, corn, squash, tomatoes, peppers, melons, etc.).
- All summer annual flowers can be planted or sown.
- Continue planting summer bulbs.
- In cooler areas east of the coastal hills, continue planting beets and carrots.
- Thin fruit on fruit trees as needed (use the width of your closed fist as a rough guide). For more information, read up on thinning here.
- Check to be sure that your irrigation system is working and meets the needs of your garden.
