A 2026 Planting Guide for Radishes: Optimal Dates and Top Varieties.

Growing Radishes in 2026

According to TSN.ua: The first radish sowings of 2026 will begin in March, offering gardeners a popular and quick-growing crop. Radishes are a favorite for their rapid cycle, taking only about a month from seed to harvest. This hardy vegetable can germinate in temperatures as low as 2–3°C, and its seedlings can withstand brief frosts down to -3°C, making it an ideal choice for early spring planting. For many home gardeners, radishes are the first fresh harvest of the year.

Choosing Varieties and Favorable Sowing Dates

Successful cultivation depends on selecting the right variety and sowing at the correct time. Early-maturing varieties, which are recommended for sowing in March and April at 15–18°C, include:

• Celesta F1
• Cherriette F1
• Sora
• Rudolph
• French Breakfast
• Diego F1

These types are genetically protected from premature bolting and mature in just 18–22 days. Mid-season varieties, planned for harvest in June, require particular attention, while late varieties are planted in late summer or early autumn. A winter sowing can also be done in November.

In March 2026, the favorable days for sowing are:

• 3
• 4
• 7
• 8
• 11
• 12
• 16
• 21
• 22
• 26
• 30

Conversely, March 1, 14, 28, and 29 are considered less favorable. For April, the optimal sowing dates are:

• 1
• 3
• 4
• 8
• 9
• 13
• 17
• 18
• 22
• 27

with April 12, 26, and 28 being less ideal. May also offers good planting opportunities on:

• 1
• 5
• 6
• 10
• 15
• 16
• 19
• 20
• 24
• 25
• 29

while May 11, 25, and 27 are not recommended.

Additionally, practicing good crop rotation is crucial. The best predecessors for radishes are cucumbers, tomatoes, potatoes, and legumes, as this helps create optimal soil conditions for growth and development. Following these agronomic recommendations is key to maximizing your yield. Given its fast maturity and ease of care, the radish remains a relevant and rewarding crop for growers adapting to increasing demand for fresh produce.
