Planting & Care

Where to Plant

Sunlight: Mars Grapes require full sun, meaning at least 8 hours of direct light daily, to develop high sugar content and deep blue color. While they can grow in partial shade, you will face increased disease pressure and significantly smaller, more acidic fruit clusters.
Soil: These vines prefer deep, well drained loamy soil with a pH between 5.5 and 6.5. If you have heavy clay, plant in a raised mound to ensure water drains away from the roots, as "wet feet" will quickly lead to root rot.

Watering Requirements

During the first two years of establishment, provide 1 inch of water per week to help the deep root system take hold. Once mature, Mars is remarkably drought tolerant, but inconsistent moisture during fruit swell can cause the grapes to crack or remain small. Aim for deep soakings at the base of the plant rather than frequent light sprinkles to encourage roots to grow downward.

Pruning Tips

This variety produces fruit on new growth coming from one year old wood, so dormant pruning in late winter is essential. Use the "Four Arm Kniffin" system or a similar trellis method to remove up to 90 percent of the previous year's growth, leaving only a few select "fruiting canes" with about 10 buds each. Thinning the vine like this ensures the plant puts its energy into high quality fruit rather than a massive tangle of unproductive leaves.

Fertilizer Needs

Apply a balanced 10-10-10 fertilizer in early spring just as the buds begin to swell to support vigorous new growth. Avoid high nitrogen fertilizers after midsummer, as this encourages soft, green growth that will not harden off before winter, making the vine vulnerable to freeze damage. If your vine is growing more than several feet per year, skip the fertilizer entirely to prevent "all leaves and no grapes" syndrome.

Understanding Our Container Sizes

At Nature Hills, our plants are sold in industry-standard nursery containers. You will notice we use the word "container" rather than "gallon." Container numbers follow a nursery trade size standard, not liquid volume. The number tells you the plant's size category and general maturity level. A larger container means a more established plant with a stronger root system.

Container Sizes

Quart

Plant age: 6 months to 1 year
Best for: Ground covers, perennials, ornamental grasses
What to expect: Our smallest and most affordable size. Well-suited for planting in multiples across a large area. Allow 1 to 2 seasons for full establishment.

#1 Container

Plant age: 1 to 2 years
Best for: Shrubs, perennials, smaller trees
What to expect: About the size of a large coffee can. A well-developed root system in a manageable size. Good value choice when you have time to let the plant grow into the space over a season or two.

#2 Container

Plant age: 2 to 3 years
Best for: Shrubs and trees where you want faster establishment
What to expect: A noticeable step up from a #1 in both plant size and root development. Good choice when you want visible presence without going to a larger size.

#3 Container

Plant age: 3 to 4 years
Best for: Most plants, most situations — flowering trees, shade trees, evergreen shrubs
What to expect: Our most popular size. Strong, developed root system. Plants in a #3 container make an immediate visual impact from day one. If you want a head start rather than waiting seasons for a plant to fill in, this is typically the right choice.

#5 Container and Larger

Plant age: 4 to 5+ years
Best for: Specimen plants, privacy screens, maximum instant impact
What to expect: Large, mature plants ready to make an immediate statement in your landscape. We also carry #7 and larger sizes for select varieties.

Why "Container" and Not "Gallon"?

Nursery container sizes follow an industry trade standard established for the nursery and horticulture industry. The number is a size designation, not a measurement of liquid volume. Actual soil volume varies by plant type, root mass, and growing medium. Using "container" is the accurate industry term. When you see #1, #2, or #3, think of it as the plant's size tier, not a gallon measurement.

Root Pouch Containers

Some Nature Hills plants arrive in a Root Pouch, a breathable fabric container made from 100% recycled materials. Root Pouches encourage denser root development through air pruning, which discourages root circling and promotes a stronger, more fibrous root ball at the time of planting.

There are two types. Knowing which one you have changes how you plant:

Degradable (brown or tan fabric): Plant the entire pouch directly in the ground. The fabric breaks down naturally in the soil over time.
Non-degradable (black or gray fabric): Remove the pouch before planting. Cut the bottom open with scissors, then peel the sides away. The fibrous root ball will hold its shape.

Not sure which type you have? Check the tag on your plant or contact us and we will confirm.
