(Best months for growing Tomatillo in Canada - Zone 6a Temperate Warm Summer regions)

  • S = Plant undercover in seed trays
  • T = Plant out (transplant) seedlings
  • Easy to grow. Grow in seed trays, and plant out in 4-6 weeks. Sow seed at a depth approximately three times the diameter of the seed. Best planted at soil temperatures between 21°C and 27°C. (Show °F/in)
  • Space plants: 70 cm apart
  • Harvest in 10-14 weeks. Husk splits when fruit is ripe..
  • Compatible with (can grow beside): Will happily grow in a flower border
  • Tomatillo Plant (CC BY-SA 3.0 WikiMedia)
  • Young tomatillo

NB: Tomatillos are not self-fertile so you need to have at least two plants for cross-pollination. Tomatillos are from the same family as Cape Gooseberries, with a papery husk round the fruit.

Tomatillo plants are similar in growth to tomatoes and spread about 1 - 1.5 m. Can be supported but are happy spreading themselves around. The plants are very productive so 2 or 3 plants may be enough for the average household.

Tomatillos will cope with cooler weather than tomatoes. The fruit will swell to fill the husk as they ripen. Do not use fertiliser.

When buying seed, check that it is Ph.ixocarpa not Ph.peruviana otherwise you will grow Cape Gooseberries instead of Tomatillos.

Culinary hints - cooking and eating Tomatillo

Use in spicy sauces with or to replace tomatoes.
They are the base of salsa verde in Mexican cookery.

Re tomatillos: I planted only one tomatillos plant (didn't realize I should have a spouse for it); fort several weeks it grew and grew but there were no indications of fruit; then the little yellow flowers started sprouting and producing fruit. I have made Salsa Verde, a delicious sweet potato/tomatillo bisque and spaghetti sauce, but I still have loads of tomatillos on my counter, in my fridge, in my freezer. This plant doesn't know how to quit. Frost is called for tonight so I suspect my plant will fall victim to winter pretty soon. My problem is that so many of the fruits were small, running from 1/2 to one inch across. Any suggestions for 2023 on how to get maybe less but larger fruit?

Look up the internet about picking off the lateral growth. Where the leaf joins the main stem a piece of growth comes out there. Pick it off.

Do you have to have 2 plants in order for it to produce fruit?

yes, these plants need a partner to pollinate, I have found 4 plants is a good sweet spot to get enough tomatillos to do some sauce making (Salsa Verde) . I hope you found your answer already as it's now so late in the season! Good Luck.

I am in Calgary Alberta and this spring I took a few tomatillo's and sliced them into 1/4 to 1/2 inch slices and planted them into dirt right away. After I started to see small plant sprouts I took the slices out of the smaller pots and planted them right into the large planter for the rest of the grow season I will be back in the fall to let you know just how they faired

Hi Annie, Wondering how your Tomatillo experiment worked out? I’m wanting to give it a try out here on the west coast!

Hello , I live In Northern California .Our location is Inland from Ocean. We do get plenty of sun in summer months into October . Do I need to cover gooseberry in afternoon heat ? I got this plant from a friend .I am learning about this Gooseberry Tomato. I want to know whether I can grow this plant behind another taller Purple Tomatillo in a separate barrel about 2 feet away and achieve cross pollination successfully ? Thank you ,Judy
