Importance of Growing Watermelons from Seed
Growing watermelons from seed grants gardeners unparalleled control over the quality and traits of their harvest. By starting from seeds rather than purchasing pre-grown plants, you have complete authority over which plants to select based on their health, vigor, and desired characteristics such as size or taste.

Watermelon plants are extremely sensitive to cold temperatures, which can stunt their growth or even kill them.
Therefore, consulting your local agricultural extension office or using online resources to determine your area's average last frost date is recommended. By aligning your transplanting schedule with this date, you can optimize the chances of a healthy and robust watermelon crop.
Preparing the planting site by amending soil with organic matter and ensuring proper drainage
Creating a favorable environment for your Jubilee Improved watermelons starts with preparing the planting site. Begin by choosing a location that receives full sunlight throughout the day, as watermelons thrive in warm conditions.
Before transplanting, it's essential to amend the soil with generous amounts of organic matter, such as compost or well-rotted manure. This enriches the soil, improves its structure, and enhances its ability to retain moisture without becoming waterlogged.
Additionally, ensure that the chosen site has good drainage to prevent excessive water accumulation around the roots. Poorly drained soil can lead to root rot and other diseases that can negatively impact plant health.
Gently remove seedlings from trays or pots, carefully not damaging delicate roots.
When it's time to transplant your Jubilee Improved watermelon seedlings into their permanent spot in the garden, handling them carefully so as not to damage their delicate roots is crucial. Start by gently tipping over each seedling tray or pot while supporting its base with one hand.
Gradually tap or squeeze the container's sides to loosen the root ball and help it slide smoothly. Avoid pulling on the stem, as this could harm the fragile plant.
Instead, hold onto an actual leaf or use your fingers to gently grasp the base of the seedling while easing it out. Once freed from its container, transfer each seedling into a shallow hole in the garden soil.
Place it at the same depth as it was growing in its original tray or pot and fill in any gaps around the roots with lightly packed soil. Remember that watermelon seedlings are susceptible to transplant shock, so don't disturb their delicate roots excessively during this process.
Being patient and gentle when handling them gives your Jubilee Improved watermelons a better chance of thriving in their new home.
