Harris Seeds Petunia Limbo GP F1

No, you do not. The Limbo GP series is genetically bred to maintain a dwarf habit, so they stay neat and tidy in pots and packs without the need for chemical growth regulators.

Pelleted seeds are coated in a clay-like material to make them larger and uniform in shape. This makes them much easier to handle and sow accurately compared to tiny, raw petunia seeds.

Since these plants have a mature spread of 15 to 18 inches, you should space them about 15 inches apart to allow for their vigorous, spreading habit while still creating a full, lush look.

Yes, they are excellent for containers. Their compact, naturally dwarf growth habit keeps them from getting leggy, while the large, grandiflora-sized blooms provide a high-impact display in smaller spaces.

For the best results, maintain a soil temperature between 70°F and 75°F. Once germinated, you should aim for daytime temperatures of 65-70°F and nighttime temperatures of 60-65°F.

This variety is specifically bred to resist stretching. You can expect them to maintain a consistent, compact, and high-quality appearance throughout the entire season.
