The best time to start growing cucumbers outdoors from seed is between April and May when you no longer have to worry about spring frost in most regions.

If you want to start your gardening project even earlier in the year, you may be better off pre-growing cucumber seedlings indoors and transplanting them outdoors once it gets warmer.

Instead, you may be better off growing cucumbers at home during the main season in spring and summer since you would just see much better results on average.

Instead of trying to grow multiple batches of cucumber seeds at different times of the year, you may be better off focusing on just one single batch of cucumber plants during the main season since later batches may just not get ready before winter frost hits.

How to water cucumber plants in Colorado?

While your plants are still small and it is rather cool outdoors during the first months of the year, you may want to water your cucumber plants in Colorado only a little bit.

However, once your plants get bigger and it gets warmer outside, you may have to water your plants almost daily so they don’t dry up and can grow in a proper manner.

Since radiation and heat are not a big deal for your plants in the early months of the year, you don’t have to protect your cucumber plants from the sun in an active manner.

Instead, you can just let them grow and once your plants get bigger, they will become more resistant to the heat anyway.

Wild animals like rabbits, voles and deer may also try getting their share of your cucumber plants and you may therefore want to install a fence or use a scarecrow to keep away those hungry intruders as best as possible.
