Bulk: RST-04-105-T Hybrid Tomato Rootstock

I planted multiple types of rootstock and this was the only variety that sprouted. I just grafted my tomatoes and don't have any results yet.

I purchased 20 seeds to use in my elementary horticulture class. I planted them in 3 six packs. I also planted some heirloom varieties in separate six packs at the same time, using the same soil source. None of the RST seeds germinated, whereas all of the heirloom seeds did. I was very frustrated as these seeds are very expensive.

I have planted with this rootstock for 3 years now and every year I have gotten better at it! These produce tomato plants that outlast my non-grafted plants by 3 months. I find the real benefit is that they produce fruit longer into the season. I live in zone 9. The roots are pencil thick and stretch way out underground. No disease and I plant in the same beds every year. I joke that the stock looks like the hulk compared to other plants. The main challenge is getting them started - you will kill many plants before finding success. I found more success grafting the scion when the plant is young (2 weeks) and using the smaller grafting clips. Good luck!
