- Watch for rapid temperature swings common in our high desert valley; use row covers to buffer plants against sudden dips below 32°F.
- Our dry, rocky soil drains fast but holds little moisture, so water newly transplanted Garlic and Daikon deeply every few days rather than daily light sprinkles.
- Avoid planting heavy feeders like corn or tomatoes yet; the cool air and short daylight hours favor cold-hardy crops over warm-season starts.

Colorado Springs gardening questions
3Can I transplant my seedlings now in Colorado Springs?
No, wait until after April 21 when the risk of frost passes completely before moving any delicate starts outside. The current cool air and potential for sudden freezes will damage most tender foliage.
How often should I water my Daikon Radish this week?
Water deeply once or twice a week to encourage deep roots, as our fast-draining soil dries out quickly between storms. Shallow watering can cause the radishes to become woody and tough in our high-altitude climate.
Is it too early to start planting tomatoes outdoors?
Absolutely not; wait at least two weeks after April 21 to ensure no late frosts occur that could kill young plants. Start indoor seedlings now, but they won't go outside until Memorial Day weekend earliest.
