Product description
This is a premium, historic dessert grapevine famous for producing large, luscious, incredibly sweet black grapes. Traditionally grown in grand Victorian glasshouses, it is a heat-demanding vine that requires optimal conditions to turn its internal starches into the complex sugars needed for a premium harvest.
To care for 'Frankenthaler', you must provide the absolute hottest, most sheltered sun-trap on your property—a baking south-facing brick wall is ideal. The soil must be exceptionally well-draining, as wet roots will ruin the harvest. You must strictly manage the summer canopy by thinning out leaves so the sun physically hits the grape clusters, and prune the woody framework hard in deep winter while the vine is dormant.
Please Note: When purchasing plants, please consider that each live item is unique and may therefore differ from the images shown, which are for illustration purposes only. The plant will be supplied in a growers pot. Depending on season, some plants may be pruned back to encourage growth and deciduous plants may arrive without leaves.

Garden Plant Size Guide
Plants in larger pots can be multiple years older than their smaller counterparts with more mature root systems and foliage. This makes them able to thrive as a full size plant in your garden quicker than smaller alternatives.
The most common size of pot that garden plants come in are 9cm/1L/3L/5L this is in reference to the diameter at the top of the pot.
9cm potted plants still remain the most popular cost effective option though, they just may take a little patience to allow them to grow into full maturity once planted in your garden.

Instructions
Top Tip
This is a premium dessert grape that demands intense heat. Give Vitis Frankenthaler the absolute hottest, most sheltered sun-trap you have on your property to ensure the fruit swells and sweetens.
How to Water
To water Vitis Frankenthaler, soak deeply every ten days in year one to drive roots down. Once mature, let the soil dry out, but maintain moisture when its premium grapes swell. Always water the soil, not the leaves.
How to Plant
To plant Vitis Frankenthaler, dig a hole twice as wide as the rootball but exactly the same depth. Incorporate plenty of horticultural grit into the excavated soil to guarantee the rapid drainage this vine demands. Position the plant so the top of the rootball is flush with the soil surface. Backfill firmly, guide the tender tendrils toward your bottom wire, and water deeply to eliminate underground air pockets.
