Plant at the Right Time

When and how you plant your crops influences the success of your garden. Some vegetables can withstand frosts, but others can’t.

Many gardeners often plant by the moon. There isn’t evidence supporting this. Plus, studies say that there are no significant differences between moon phases and crop production.

The best thing to do is to research the plant you’re dealing with and determine whether or not it can handle frost. Then, decide the best planting time for it. Also, when planting, ensure that your seed is disease-free and plant in straight rows for a beautiful garden.

Additionally, hill the seed. Hilling involves placing various seeds on a single spot at definite intervals in the row. Most gardeners use this style to plant cucumbers, melons, squash, and sweet corn. Or consider drilling, which involves spacing the seed using your hand or a drill.

Also, remember to space your seeds correctly and plant at a proper depth.

Play with Colors

Incorporate more color in your garden. The good news is that there are many low-maintenance, colorful, and hardy plants you can consider. Some of them don’t even require you to spend a lot of time raking or trimming.

Some plants that can brighten up your yard include Purple Prickly Pear, Mexican Fire Barrels, Golden Barrels, and Mescal Ceniza.

Choose Your Plants Wisely

If you are going to mix crops, make sure that they have similar needs. Note that if you mix plants with low, moderate, and high water needs, you’ll have a hard time keeping a healthy landscape and meeting the needs of each plant. You may overwater some plants and underwater others.

Therefore, avoid this by planting crops with almost the same needs. For instance, pumpkin and squash go well together. Do some research to determine the best combinations.

Think of Design When Grouping

A well-designed garden is every farmer’s dream, and how you group your plants determines the appearance of your garden. Check ideas from professional designers and see what works for you. You can design your garden in a sculptured and planned design with the same types of two or three plants in neat arrangements.

For instance, you can have one round group, another triangular, and another group of tall plants together. This creates a visually appealing arrangement.
