If I have questions or I would like to order some grafted plants what do I do?

Please contact your local TriEst Ag sales staff or one of our Sales Coordinators.

Can I supply my own seed or can you supply the seed for me?

We like to always supply your seed. However, you can supply your own seed but we cannot guarantee we will deliver the number of plants you ordered because we probably don’t have any experience with the lot and batch number. Also, we only take unopened seed bags with disease certification.

How much do I need to decrease my plant population when using grafted watermelons?

When planting grafted watermelon, we recommend planting about 2/3 the number of plants you would if you were planting non-grafted watermelons. For example, if you would plant 1,800 non-grafted plants per/acre, we recommend planting 1,200 grafted plants per/acre.

Do I need to use the same pollinizer ratio when using grafted plants?

If using grafted pollinizers then yes use your normal ratio. If using standard or non-grafted pollinizers then a higher ratio is recommended. However, we do not recommend using non-grafted pollinizers with grafted seedless.

Do grafted plants cause my watermelons to increase in size?

Short answer is yes. We do see bigger sizes in grafted watermelons because of the vigor of the rootstock and the lower plant population. It is very important to pick the right variety of watermelon to get the size you need.

What rootstocks do you use for watermelons?

C. maxima x C. moschata or interspecific hybrid squash. We are beginning work with the Carolina Strongback, a new citron rootstock cultivar, as well.

What are the differences in the two watermelon rootstocks?

The interspecific squash has good vigor and good resistance. However, it does not have any nematode resistance. The Citron has good vigor, good disease resistance, and nematode resistance as well.

Do you offer pinched tomatoes?

Yes, we can pinch tomatoes above the cotyledons or at the second true leaf.

What types of tomatoes do you graft and what rootstocks do you use when grafting?

We can graft all types of tomatoes for all types of cultural practices. We try to match a rootstock with your variety based on your cultural practice and what issues you may be having.
